OUTLOOK ON CANDLES FOR FALL-WINTER 2007-2008

October 11th, 2007

Re-print form Natrional Candle Association http://www.candles.org/index.html

Candles of every imaginable shape, color and fragrance continue to capture the fancy of American consumers, whether they’re seeking to add a distinctive decorative element or sensory aesthetic to their homes.

Nearly half of all American women say they specifically use candles as part of their decorating scheme, and the growing popularity of “scenterior” design – combining fragrance and color to create a full sensory aesthetic in the home – is a driving force in candle sales.

Not surprisingly, the season’s newest candle fragrances and colors reflect the latest emerging fashion and design themes. Nuanced colors reminiscent of Old World opulence are taking center stage, along with calming but complex fragrances that hold a hint of the exotic. Greyed and inky blues, fresco golds, blondes and apricots, burnt reds, subtle gray-greens, charcoals, chocolates, metallic neutrals, and deep dusky purples define the new color palette.

The latest offerings in candle fragrances reflect the same ethereal opulence. Lush but unusual blossoms, such as peonies, sweet peas and Asiatic lilies, are capturing consumer imaginations. And while more traditional floral and citrus scents remain popular, they’re often tempered with subtle notes of patchouli, amber, pepper, teas or exotic orientals

In addition to home décor candles, consumers continue to purchase scented candles for mood setting. Here the trend is toward a luxury “spa” look and style. Clear glass cylinders (with or without lids) remain the most popular. Unlike home décor candles where color abounds, spa-style candles tend to feature white, ivory or the palest of pastel wax colors to focus attention on the fragrance. Lavender and vanilla scents remain perennial favorites, but the fragrances are sophisticated and soft. Subtle notes of mint, ginger, amber, cassis, patchouli, pepper, hazelnut, jasmine, gardenia, pink grapefruit, currant, berries and rosemary are often favored.

An estimated 80 percent of all candles sold in the U.S. are scented, reflecting America’s continuing love of fragrance in home, fashion and lifestyle purchases. Overall, annual U.S. retail sales of candles are estimated at $2 billion, excluding candle accessories.

Diameter Estimate for Irregular jars

October 2nd, 2007

 The process of wick selection for a container candle includes determining the diameter or effective surface area of the container that they candle will be poured into. Sometimes this is easy like when the container is an apothecary or melt jar, which is like a cylinder and has a single diameter or can be more difficult when the shape of the container is irregular and has a changing diameter from the top to the bottom as with a honey pot or bulb style container jar.

If too large a wick is selected there may be excessive heating of the container during burning where the diameter is small and if too small a wick is selected tunneling may occur where the diameter is large.

Using the maximum diameter as the estimate of the container’ diameter can be misleading if there is a large deviation between the smallest and largest diameter of the jar. Some ‘shapely’ containers have more than an inch variation between the largest and the smallest diameter and to complicate the estimate further these diameters only exist at one point in the jar and aren’t representative of  the jars wicking needs. Thus, taking an average of these two numbers can be misleading as well.

Since only one wick or set of wicks is going to be used over the life of the candle the best estimate for the effective diameter would be a true average. An easy and direct method to estimate a containers average diameter uses data on the height that the container candle will be poured to in the jar and the volume of the container at this point. A simple relationship between the volume of a cylinder and the actual volume of the container can be used to determine true average diameter of the container.

The process goes like this:

Measure your containers volume by marking a line on the container where the wax pour will stop. Fill the container up to this point with room temperature water and then pour that amount of water out into a measuring cup or graduated cylinder, if you have one, of appropriate size Record this value; say 16 ounces for example’s sake. (If you have a scale handy a more accurate method is available to measure the volume of water added using the difference between the weight of the container before and after the water is added to the container. Take this difference value and divide by 1.043 and you have the volume of water in ounces). Next measure the distance from the inside bottom of the jar to the pour line you previously marked. Record this value; say 3 inches. Using the following equation relates the diameter of a cylinder with the same volume and height of your container to your container’s average diameter:

Average Volume = 2 x Sqrt( 1.8047 x Vc / Pi / h)

Where Vc = the volume of your container, here 16 ounces

                        Pi = 3.14159

                        1.8047 converts ounces to cubic inches

                        h = the height of your pour line, here 3”

                        Sqrt is the square root function

Example:  Average Volume = 2 x Sqrt( 1.8047 x 16 / 3.14159 / 3) =  3.5 inches 

The calculated diameter is the best diameter to use when selecting a range of wicks to test in your container jar candle as it represents the smallest error in fitting the perfect wick during the entire burn of your candle

Colorants Used In Candles

September 27th, 2007

Re-printed from National Candle Association http://www.candles.org

Candles are available in a seemingly endless palette of colors, from luminescent shades of ivory to deep rich jewel tones, pastels, metallics and chromatic layers. In addition, candle manufacturers introduce new hues and shades each year, reflecting the emerging color trends in interior design and fashion.

Although candle color is the second-most important factor (after fragrance) for influencing consumer purchasing decisions, color and fragrance are closely linked. In fact, research has shown that consumers expect the color of a scented candle to mirror their psychological perception of the fragrance. A cinnamon-scented candle, for example, is expected to fall somewhere in the red-bronze palette, while “mountain breeze” draws expectations of a candle in the pale blue or green shades.

Reputable candle manufacturers must combine the art and beauty of color with the science of candle formulation to develop aesthetically pleasing candles that will burn properly and safely. Selecting the proper type and amount of colorant to use in a candle will vary according to the type of wax, wick and fragrance used in formulating the candle.

Dyes vs. Pigments

Specially-formulated pigments and dyes are used to color candles. Dyes have different properties from pigments, and are used to create different effects. In general, pigments are used to coat the outside of a candle with color, while dyes are used to color the candle throughout.

Dyes

Available in both liquid and powder form, dyes give a candle its translucent color. Dyes also provide the candlemaker with a large degree of control over a color’s shade. Because dyes are easily combustible, they will not clog a wick, and generally have a minimal effect on the burn performance of a candle.

Pigments
 
Pigments are microscopic, suspended color particles that create a solid wall of color, similar to paint. They do not dissolve, migrate or “bleed,” and thus are not as susceptible to color fade as dyes.  Pigments usually do not burn well, and the color particles will clog a wick if burned.  This makes them unsuitable for a candle that is colored throughout and meant to be burned, but useful for coating the outside of the candle.

Both pigments and dyes are safe when used as intended, and there are no known health concerns with either type of colorant. NCA members use high-quality dyes and pigments that are recognized as safe for combustion.

Colorant Formulations

Reputable candle manufacturers work closely with colorant companies to develop color formulations that will match the burn characteristics of the candle and provide the exact desired shade. The addition of colorants will not cause a properly-formulated candle to soot. Sooting is primarily a function of wick length and flame disturbance. Candle dyes can be affected by heat, light, fragrance and other agents in a candle. These harmless reactions can slightly alter a candle’s color over time, but will not affect the candle’s burn properties or safety.

Fragrances Used In Candles

September 27th, 2007

Re-printed fron National Candle Association http://www.candles.org 

The addition of fragrance to a candle formulation is commonplace in the United States. In fact, an estimated 75 percent of candles sold in the U.S. are scented. Candle manufacturers work closely with fragrance companies to develop scented formulations that are not only pleasing, but will burn safely and properly.

The aroma from a lighted scented candle is released through the evaporation of the fragrance from the hot wax pool and from the solid candle itself. Like unscented candles,

properly-formulated scented candles will primarily produce water vapor and carbon dioxide when burned. The only difference is that a fragrance is also released with a scented candle.

Most scented candles contain a combination of natural and synthetic fragrances These fragrance materials may be derived from essential oils or from synthetic aroma chemicals. A well-made candle will contain only fragrance materials approved for candle use; the addition of fragrance to a candle formulation should be carefully monitored to ensure that the candle will burn cleanly and properly.

Candle manufacturers can select from an estimated 500 to 800 aroma chemicals and essential oils to develop scents that are both pleasing to consumers and compatible with candle use. These fragrance materials are safe, high-quality ingredients that are also found in many perfumes, bath soaps, lotions and shampoos.

Various health and safety tests are conducted on the raw fragrance materials that are used in candles and other consumer products. Reputable candle manufacturers use only expertly-formulated fragrances specifically approved for candle use.

Fragrance Questions & Answers

Q: Are scented candles safe?
A: Yes. Decades of research and a history of safe use in the marketplace support the safety of fragrances in candles. A well-made candle produces water vapor and carbon dioxide when properly burned; the only difference with a scented candle is that a small amount of fragrance is also released. Reputable candle manufacturers use only fragrances approved for candle use, and test their candles to ensure a clean and proper burn.

Q: What makes a candle an aromatherapy candle? Most fragranced candles are not true “aromatherapy” candles.
A: Aromatherapy calls for creating physiological or therapeutic effects through the use of essential oils extracted from plants and absorbed in the body through massage, ingestion or smell. Many scented candles do not contain essential oils; those that do rarely contain amounts large enough to produce true aromatherapy effects. Instead, most scented candles create pleasing psychological effects from the ambient aroma of fragrances. This is often referred to as “aroma-chology.”

Q: Do scented candles soot more than unscented candles?
A: Although the oils found in certain fragrances may slightly increase the small amount of soot that a candle may produce, a well-formulated scented candle will burn cleanly and will not produce any significant amount of soot. As with any candle, the primary factors that cause sooting are flame instability and a too-long wick, not fragrance or color or wax type. NCA-member candle manufacturers work closely with fragrance manufacturers to ensure that fragrances are appropriately incorporated into candle formulations to result in scented candles that burn safely and properly.

Q: Are scented candles that use essential oils safer?
A:No. A natural ingredient is not necessarily any safer than a manufactured or synthesized ingredient, and some essential oils are extremely toxic to humans in very small amounts. NCA members are committed to using fragrances that are safe and approved for use in candles, whether “natural” or synthesized.

Q: Is there such a thing as too much fragrance in a candle?
A: Yes. For every candle formulation, there is a maximum amount of fragrance that can be added before the candle will no longer burn properly. NCA members carefully monitor the addition of fragrances to ensure that their scented candles will burn cleanly and safely. There have been some reports of homemade and craft-fair candles containing too much fragrance, or fragrances not approved for candle use. This can lead to improper burn performance or excess sooting.

Q: Are lead-core wicks found in scented candles?
A: It’s unlikely. Lead-core wicks have been banned from the U.S. since 2003, and members of the National Candle Association – which account for more than 90% of candles made in the U.S. – have not used lead wicks for more than 30 years. Reputable manufacturers use cotton, cotton-paper, zinc-core or tin-core wicks, all of which are known to be safe.

Q: Are the fragrances used in scented candles tested for health effects and safety?
A: Health and safety studies are conducted for fragrance materials, including toxicological and dermatological tests. The Research Institute for Fragrance Materials (RIFM) tests individual fragrance materials, develops testing protocols, and collects fragrance safety data from around the world. RIFM submits its finding to the International Fragrance Association, which establishes safety guidelines and standards for fragrance manufacturers worldwide.

Q: Do scented candles emit dangerous amounts of toxic pollutants into the air?
A: No. A properly-formulated candle, whether scented or unscented, will primarily produce water vapor and carbon dioxide when burning correctly. While microscopic amounts of organic compounds or special ingredients used to formulate a particular scented candle may be released when a candle is burned, they are too minimal to pose a health risk.

Q: Are scented candles triggers for asthma and allergies?
A: Millions of Americans, including allergy and asthma sufferers, use scented candles without any negative effects. However, it is always possible a particular fragrance may trigger a negative reaction in sensitive individuals. People with known sensitivities to specific fragrances may wish to avoid candles of those scents. In addition, consumers should remember to burn all candles, scented or otherwise, in well-ventilated areas.

Wicks – Facts

September 27th, 2007

Re-printed from National Candle Association http://www.candles.org

Most consumers usually think of a candle’s shape, color or fragrance as its most important element. Most candle manufacturers, though, would probably say it’s the wick that makes the candle.

The purpose of a wick is to deliver fuel (wax) to the flame. Acting like a fuel pump, the wick draws the liquefied wax up into the flame to burn. Different wick sizes allow for different amounts of fuel to drawn into the flame. Too much fuel and the flame will flare and soot; too little fuel and the flame will sputter out.

All wicks consist of a bundle of fibers that are either twisted, braided or knitted together. These fibers absorb the liquefied wax and carry it to the flame by capillary action.

There are more than 100 unique wicks on the market today. The type of wax used in a candle, as well as the candle’s size, shape, color and fragrance materials all impact wick choice. Selecting the correct wick is critical to making a candle that burns cleanly and properly. Reputable candle manufacturers take great care in selecting a wick of the proper size, shape and material to meet the burn requirements of a particular candle.

Types of Wicks

Most high-quality wicks are made from braided, plaited or knitted fibers to encourage a slow and consistent burn. In general, twisted wicks are of lower quality than braided or knitted wicks. They burn much faster because their loose construction allows more fuel to quickly reach the flame. However, twisted wicks are useful for certain applications, such as birthday candles.

In general, wicks can be divided into four major types:

  • Flat Wicks. These flat-plaited or knitted wicks, usually made from three bundles of fiber, are very consistent in their burning and curl in the flame for a self-trimming effect. They are the most commonly used wicks, and can be broadly found in taper and pillar candles.
  • Square Wicks. These braided or knitted wicks also curl in the flame, but are more rounded and a bit more robust than flat wicks. They are preferred for beeswax applications and can help inhibit clogging of the wick, which can occur with certain types of pigments or fragrances. Square wicks are most frequently used in taper and pillar applications.
  • Cored Wicks. These braided or knitted wicks use a core material to keep the wick straight or upright while burning. The wicks have a round cross section, and the use of different core materials provides a range of stiffness effects. The most common core materials for wicks are cotton, paper, zinc or tin. Cored wicks can be found in jar candles, pillars, votives and devotional lights.
  • Special and Oil Lamp Wicks. These wicks are specially designed to meet the burn characteristics of specific candle applications, such as oil lamps and insect-repelling candles.

Wick Use in the U.S.

Approximately 80 percent of the wicks manufactured in the United States are made of all-cotton or cotton-paper combinations. The remainder are primarily metal- and paper-cored wicks.

Lead wicks were banned from the U.S marketplace in 2003, and for several years before that were found primarily in inexpensive foreign candle imports. NCA-member manufacturers voluntarily discontinued using lead wicks in the mid-1970s, and in 2000, asked all U.S. candle manufacturers to join its members in signing a formal pledge not to use lead wicks.

The metal-core wicks sometimes found in candles are typically zinc- or tin-core wicks. They are most often used in container candles and votives to keep the wick upright when the surrounding wax liquefies. Scientific studies have repeatedly shown both zinc- and tin-core wicks to be safe.

Wax – Facts and History

September 27th, 2007

Re-printed from National Candle Association http://www.candles.org 

Over the centuries, candle waxes have been developed from a variety of fats, oils and waxy-like substances derived from animals, insects, plants and rocks.

Scientists consider “wax” to be a generic term for classifying materials that have the following characteristics:

  • Solid at room temperature; liquid at higher temperatures
  • Primarily hydrocarbon in structure
  • Water repellent
  • Smooth texture; buffable under slight pressure
  • Low toxicity; low reactivity
  • Low odor
  • Combustible

Waxes are widely used throughout the world for a wide range of applications, including packaging, coatings, cosmetics, foods, adhesives, inks, castings, crayons, chewing gum, polishes and – of course – candles.

Development of Candle Waxes

“A tallow candle, to be good, must be half Sheep’s Tallow and half Cow’s; that of hoggs mekes ‘em gutter, give an ill smell, and a thick black smoak” Anonymous 18th Century

Early civilizations depended largely on the raw materials at hand to create candle wax. Ancient Egyptians and the Early Romans relied largely on tallow rendered from animals.

In China, beeswax was used for candles as early as the Tang Dynasty (618-907 A.D.), and candle wax derived from the Coccos pella insect had been developed by the 12th century. Extracts from tree nuts were used to make candle wax in early Japan, while in India they boiled the fruit of the cinnamon tree for candle wax.

Beeswax was introduced to Europe in the Middle Ages, but was rarely used in homes because of its great expense.

Over the centuries, the development of new waxes for candles has hinged on the availability of the raw material, the ease and economy of processing the raw material into a wax suitable for candle use, and the desirability of the wax in comparison to other available candle waxes.

Tallow was the typical everyday candle wax used in Europe and the Americas until the 18th century, when the whaling industry stimulated the development of spermaceti wax, a clean-burning, low-odor wax derived from the head oil of the sperm whale.

Spermaceti remained the primary candle wax until the mid-1800s, when stearin wax and then paraffin wax were developed. Stearin wax, based on extracting stearic acid from animal fatty acids, was widely used in Europe. Paraffin wax, developed after chemists found a way to remove the naturally-occurring waxy substance from petroleum during refining, became the standard candle wax in the Western Hemisphere.

During the latter half of the 20th century, several synthetic and chemically synthesized waxes, including gels, were developed largely for specialty candle uses. Two vegetable-based candle waxes – soy wax and palm wax – were developed for commercial use in the candle market during the late 1990s by hydrogenating soybean and palm oils, respectively.

Paraffin is by far the most frequently used candle wax on a worldwide basis today. Beeswax is also used around the globe, although in significantly smaller quantities. Stearin candle wax is largely limited to European use. Soy wax, palm wax, gels, synthetic waxes, and synthesized waxes are also now used in candles, as are a variety of wax blends and customized wax formulations.

Candle Wax Facts

  • Prior to the 19th century, a “wax” candle typically referred to a beeswax candle
  • All waxes are primarily hydrocarbons, whether the wax is of animal, vegetable, or petroleum origin. The chemical composition of all waxes used for candle-making is similar
  • An estimated 1 billion pounds of wax are used in the candles sold each year in the United States
  • Candles account for the second largest use of waxes in North America, after packaging and package coatings
  • Paraffin is the most commonly used candle wax today. Beeswax, soy wax, palm wax, gels, and synthesized waxes are also used in candle-making for the U.S. market, as are blends of waxes
  • Waxes burn with a yellow flame due to the presence of carbon.
    No specific type of wax or wax blend is considered “best” for candlemaking. All candle waxes – when provided in high-quality format – have been shown to burn cleanly and safely
  • No candle wax has ever been shown to be toxic or harmful to human health.
    There is no such thing as a soot-free wax. All organic compounds when burned will emit some carbon (soot) due to incomplete combustion. Sooting is primarily a factor of wick length and disturbance of the flame’s steady teardrop shape
  • Reputable candle manufacturers use only high-quality waxes in their formulations

 

OUTLOOK ON CANDLES FOR FALL-WINTER 2007-2008

CANDLES ARE “SCENT-SATIONAL”

September 27th, 2007

Re-print from the National Candle Association http://www.candles.org/index.html 

VANILLAS, FLORALS ARE MOST POPULAR

Candle fragrance isn’t just an after-thought, it is the driving force among consumers deciding which candles they will purchase. Consumer surveys by the National Candle Association (NCA) have shown that 75 to 80 percent of candle users – both male and female – consider fragrance to be the leading factor in determining their purchase of a candle. Color is usually the second-most important factor.

“The demand for scented candles has continued to grow over the past decade, says Valerie Cooper, NCA executive vice president. “Consumers use scented candles to create atmosphere and enhance mood,” she adds. Approximately 80 percent of all candles sold in the U.S. are scented.

With more than 10,000 different candle scents to choose from, and continued consumer interest in using fragrance to relax or improve their sense of well being, the popularity of scented candles remains robust.

In addition, scientists are learning more about aromachology — how aromas alleviate stress, heighten mood, enhance sex drive and even affect alertness in the office by stimulating olfactory pathways to the brain. In general, scented candles produce aromachology rather than aromatherapy effects.

Strictly speaking, “aromatherapy” is a holistic or alternative medicine treatment that is designed to create physiological or therapeutic effects through the use of essential oils extracted from plants and absorbed in the body through massage, ingestion or smell. Many scented candles do not contain essential oils, while others rarely contain amounts large enough to produce true aromatherapy effects. Instead, most scented candles are aromachology candles, which create pleasing psychological effects from the ambient aroma of fragrances.

Guide to Popular Candle Fragrances:

Vanilla Category — For many years, vanilla and vanilla-based aromas have been the most popular candle scent throughout the seasons. The most popular vanillas today are often combined with other fragrances to create sophisticated vanilla scents. In terms of aromachology, vanilla is thought to promote relaxation, ease a queasy stomach, promote weight loss and serve as a natural aphrodisiac.

Fruit Category — During the spring and summer months, the “fruits” as a fragrance category enjoy popularity with candle consumers. Top picks in this category include the citruses, black cherry, melon and melon combinations, apple, peach and pomegranate. Of the fruit scents, lemon has long been a favorite for stimulating the immune system, improving circulation, enhancing mental acuity and promoting relaxation.

Floral Category — The floral category includes fragrances such as rose, lilac and gardenia, as well as herb flowers. Tea rose, lilac, jasmine, and lavender are especially popular. In terms of aromachology, lavender is thought to promote relaxation and lift the mood, relieve headaches, improve the appetite and circulation, relieve insomnia and serve as a natural aphrodisiac. Jasmine is seen as decreasing anxiety, stimulating feelings of well being, easing cold symptoms and serving as a natural aphrodisiac.

Relaxation/Spa Category – This category includes fragrances such as ylang ylang, mint, ginger, green tea and eucalyptus, which are often used in day spas and resorts to create a sense of calm and well-being. Ylang Ylang is believed to decrease anxiety, slow breathing, lower blood pressure, lift the mood, improve circulation and reduce insomnia. Sandalwood, which also falls into this category, is believed to help regulate one’s mood, treat insomnia and reduce nervous tension.

Edibles Category – Beyond vanilla, fragrance experts in the candle industry have witnessed a surge in popularity of the edibles category. These scents — such as sugar cookie, apple pie, gingerbread, mocha, coffee, and hazelnut — are often associated with the pleasant aromas and comfort of grandma’s kitchen.

Scented Candles – A Market Study

September 27th, 2007

Since the explosion of candles sales in the 90’s there have been some major developments driving the market place, some news good some news not so good. Declines in the economy after September 11, 2001 has been universally felt in every category of discretionary spending, save a few. The good news is that the environmental fragrance market has actually increased sales volume in each year since that date and continues to grow, albeit, at a slow rate. This market includes scented candles, potpourri, reed diffusers, and incense.

Market growth – early years

Although considered by some to be a mature market the environmental fragrance market has been growing steadily since the 90’s boom and is estimated to be a $2.4 billion market at this time.

Heidi Kessler and Richard Roth decided to make their own soybean wax and start an organic candle business, Lumia Organic Inc., in the summer of 2003. Roth said soy wax candles started seven years (eleven years today) ago when people became aware of the fact that paraffin candles emitted large amounts of pollutants into the air. The trend for ecologically friendly or green technologies has grown and soy wax fits the specification nicely.

“The market for soy wax candles perhaps is growing at a rate of 80 percent per year,” Roth said. “Its the fastest-growing segment of the candle marketplace.”
 
Another perspective from the director of marketing at Hanna’s Candle Co is that the hottest product segment in the home fragrance category is scented candles, and the hottest trend in scented candles is soy.[1]

“It is amazing how quickly soy has soared in popularity among consumers,” says Annett Davidson.

The sudden increase in consumer awareness of and demand for soy candles is another manifestation of the class to mass trend that is driving the overall fragrance category, Davidson believes.

“Consumers want to be able to buy prestige fragrances at affordable prices, and the place they expect to do that is in a mass market retail store,” she says. “The same dynamic is apparent in home fragrances. Shoppers are turning to discount stores, drug stores and supermarkets to find the upscale soy candles they could only buy in department stores and other prestige outlets before.”[2]
 
The natural movement that is bringing new life to many mass market categories is also delivering shoppers to the $2 billion plus candle business. Retailers say the business is propelled by the true users, who tend to burn candles within a week of purchase. Many of these consumers are drawn to aromatherapy products and more and more demand “green” products.

“We see an opportunity with a great product line to start small and keep up with demand for candles that are all natural and fit into the channels dealing with wellness,” explained Rick Ruffolo, senior vice president of brand, marketing and innovation at Yankee Candle Co.,

Grocery and drug store chains and the ranks of natural-only stores such as Whole Foods, which are adding more mini clinics and boosting a health care image, are also logical doors for more aromatherapy and natural candles.

“We are looking at the channels who have embraced natural and wellness, and to align our efforts,” said Ruffolo. Among the retailers extending natural sets are Shaw’s, Fred Meyer, Harris Teeter, Dominick’s and Wegmans. Candles are merchandised in natural areas near foods and health and beauty aids.
 
A major conclusion according to some studies is that certain pockets of the country are populated by so-called ‘natural lifestyle’ consumers that could represent as much as 30 percent of the population. This means that consumers who are looking for healthier groceries will also want candles that will enhance their overall wellness. The candles carry attractive gross margins and are priced between $6 and $21.

Natural candle products are building sales rather than cannibalizing from existing candle sales, said Ruffolo. Yankee Candle Co.does think more and more shoppers have a burning desire for its natural formulations.[3]

Market Growth – today

A higher importance on comfort in lifestyle has consumers spending more money on home decor, creating a gain in 2005 candle sales. Shoppers who place higher emphasis on quality are willing to pay top dollar to make their homes look and smell nice with premium products. Scented candles have become a large home fashion category as people equate lighting and fragrant environments with a “feel good” factor. Candles have also become a popular gift trend, as the top-selling segment in the giftware industry last year was home decorative accessories. The category had $14.9 billion in sales, a 13% increase from $13.2 billion in 1998, according to Unity Marketing, Stevens, Pa.[4]
 
Annual United States retail sales of candles are estimated at about $2.4 billion. There are more than 400 commercial, religious and institutional manufacturers of candles in the U.S., plus many more small craft producers. About half the candle sales in the U.S. are of foreign-made products, with China the largest supplier nation.[5]
 
The National Candle Association (NCA) estimates that candles are used in seven of 10 households in the United States, with two-thirds of candle purchasers saying they use them once a week or more. Fragrance is by far the most important characteristic impacting candle purchases today, according to the NCA, with 75% of candle buyers saying it is either “extremely important” or “very important” to the selection process.

Market analysts at Mintel International claim that candle sales have fallen at an inflation-adjusted rate of 7 percent over the past five years, to $2.34 billion in 2006. They also predict sales will decrease another 1 percent by 2010 and that brand loyalty is sparse. According to one of Mintel’s surveys published earlier this year Some 36 percent of consumers said they were unaware of the brand of candle they bought in the past two years.
 
Contradicting the studies and reports by Mintel International Procter & Gamble Co., based on its own research, says the sales trend is actually up, not down. The Cincinnati-based consumer-products giant estimates scented-candle sales have been growing about 7 percent each year for the past four years.
 
So sure of its findings that nearly 90 years after the rise of electric lighting forced the company to stop making candles, P&G is selling candles again.  This time around, though, the company says its candles will do more than just light a room. The candles are the latest addition to P&G’s Febreze line of room sprays and plug-in deodorizers and represent an interesting experiment in brand extension. Febreze, though, is aiming to attach itself to a concept — freshness — rather than any specific item.

The candles also are P&G’s bid to make the leap from keeping house into decorating it. While Febreze’s plug-ins and spray cans are typically hidden in wall outlets and cupboards, P&G hopes its candles will wind up in more prominent places, such as on counters and end tables.[6]
 
A different Mintel study reports that the high-end segment is the only candle segment that continues to see strong growth, in large measure because luxury manufacturers have positioned their products as home decor items. As a result, the sales in the luxury segment rose from $132 million to $772 million in the period from 2004 through 2006.

The expansion of candles in the mass market has accounted for a significant proportion of the high-end growth. Initiatives such as the creation of Yankee Candle boutiques in Bed Bath & Beyond and Linens ‘N Things certainly helped raise awareness of the luxury part of the business and help lead their sales for fiscal 2006 to $687.6 million, a 14.4% increase over fiscal 2005.

The same Mintel study indicated that the percentage of people who purchase candles rose from 64% in 2002 to 77% in 2006 and reported that 65% of men said that they purchase candles. Almost one-third of consumers said that they now purchase candles once per month or more. Also, Mintel identified that companies still suffer from a lack of product distinction. In the study, even Yankee Candle got only 39% of responses regarding the candle brands purchased within the last two years, while 36% of candle buyers were hard pressed to name any brand they have purchased at all in the time period.[7]

Products and Sales

The consensus among retailers recently surveyed is that consumers are choosing candles by scent.

“It’s very seasonal,” says Tom Valentine, co-owner of Valentine’s, Newburyport, MA, “The old scents…like vanillas… no one seems that interested in anymore.”

“I don’t really see a trend,” agrees Stephanie Roe, owner of Mima & Co., Doylestown, PA. “If they smell the scent or like the shape they’ll pick it up.”

Lynni Megginson of LM Designs, Gaithersburg, MD, feels that color is as important as scent, at least when it comes to dissuading a buyer.

“Some of these way-out colors don’t translate well because they don’t fit with most customers’ home decor. The manufacturers try to coordinate the color of the candle with the scent, but I don’t think that’s important”, she says.

Retailers also reported strong sales for alternative sources of home fragrance, especially those without an open flame. Potpourri, plug-ins and candle warmers are popular, as are reed diffusers and fragrance lamps. Only one retailer felt that scent delivery systems were replacing candles sales, however. The rest said supplemental fragrancers are either purchased by customers who can’t burn candles (such as college kids in dorms or senior citizens), or for use where candles aren’t practical, such as in a bathroom.

Container candles are the big winners for almost everyone. That includes traditional, lidded jar styles as well as filled glass in smaller, design-oriented shapes, ceramics, tins and other options.

“Anything in a beautiful glass container,” explains Leigh Gill, George Watts & Son, Milwaukee, WI, when asked about her best sellers. “Something that’s more that just a candle, [like] a vase or a decorative piece that just happens to be a candle.”
 
Votives are also popular, in some stores eclipsing even container sales in numbers, if not dollars. The “sweet spots” for candle pricing are $10-$20 for basic consumers, $20-$30 for mid-range, and $30-$45 for high-end or luxury stores (sometimes even higher for a large piece that has home decor elements). When buying smaller, cheaper candles like votives and tarts, says Coppola, customers generally buy three or four at a time, bringing the total sale to the $10 range.[8]

The Science of Candle Wicks – 101

September 26th, 2007

The wick in a candle is often times an overlooked factor or certainly an under valued contributor to the performance of how a candle burns over its lifetime. An improperly wicked candle can lead to severe fire safety issues and is a known cause of indoor air pollution that can cause sooting of ceilings and walls and respiratory health issues. Thus the understanding of the science of how a wick works within a candle system can lead to a better choice during wick selection and a minimization of these risks.

The basic function of a wick within a candle system is to provide a place to develop and sustain a flame during burning. In its simplest form a wick can be a woven natural fiber such as cotton or as complex as a composite of several materials natural and man-made with a metallic core.

When a wick is lit the heat of the flame melts the wax at the top of the candle and the capillary action within the wick forms a pipeline that feeds the liquid wax to the flame. The liquid wax then vaporizes causing a chemical reaction to occur between the vaporized wax hydrocarbons and the oxygen in the air.When you take a look at the candle’s flame you will notice that the flame is nearly invisible near the wick and a yellow luminous zone surrounds it. It is there that the wax hydrocarbon molecules are broken down and release hydrogen and long unsaturated carbon chains. These carbon chains are actually tiny particles of soot that burn and release the yellow light of the candle’s flame.

If the correct ratio of oxygen to wax vapor exists at the wick the soot particles and hydrogen molecules are completely consumed or converted into heat, light, water and carbon dioxide, which are the byproducts of complete combustion. If there isn’t enough oxygen or if there is too much wax vapor at the wick the combustion will be incomplete and the flame will release the byproducts of complete combustion along with uncombusted soot and carbon monoxide. The uncombusted soot causes the wick to bloom or ‘mushroom’ and is also released in to the air along with the carbon monoxide forming air pollutants.

All flames that consume hydrocarbon vapors produce incomplete combustion and some systems produce more or less than other system do. The temperature of the flame, the mass of wax available for melting and its melting properties, the liquid transport properties of the wick (burn rate), and the length of the burning wick are some of the factors that determine the equilibrium ratio of oxygen to wax vapor that determine the amount of incomplete combustion.

For a given container candle system the container is fixed and so will be is its diameter and the mass of wax available for melting. The wax recipe is fixed and so will be its melting properties and flammability.  Thus the last controllable factor of significance is the wick. Given that there are many possible wick materials, combinations of materials and sizes to choose from selection of the wick can be a daunting task. Methodologies more efficient than trial and error can be employed to evaluate and determine if an optimum wick selection is possible for a given system. Experimental design is one of the methods and will be discussed in detail in another article.

The wick must be well matched to a given candle system so that it can deliver an optimum amount of vapor to the flame to reduce the rate of incomplete combustion and minimize the release of air pollutants into the home
