Consumers can be confident that a well-made and properly burned candle, whether scented or unscented, will burn cleanly and safely. Although there are no known health hazards associated with the use of scented candles, unfounded concerns about the safety of man-made fragrances vs. \u201cnatural\u201d fragrance materials and essential oils continue to populate the media. The fragrances approved for candle usage \u2013 whether synthesized or \u201cnatural\u201d \u2013 do not release toxic chemicals.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Validated scientific studies have shown that all major candle waxes exhibit the same basic burn behavior and produce virtually identical combustion byproducts, both in terms of composition and amount. To date, no peer-reviewed scientific study has ever collected or analyzed any emissions data on any candle wax, including petroleum-based paraffin, and proven them to be harmful to human health.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

VOCs are compounds that are composed primarily of carbon, oxygen, and hydrogen that can evaporate into the air. In addition to its evaporation capability, you can identify VOCs by your ability to smell them. Therefore, nearly all fragrance ingredients in a candle are VOCs.<\/p>

Not all VOCs are bad, unlike what you may have heard on the news.\u00a0 Every time you walk into a botanical garden or a forest, you are surrounded by VOCs from the plants. Many fragrance ingredients in a candle are identical to VOCs in nature.\u00a0 Other fragrance ingredients do not exist in nature, but are instead made in a laboratory.<\/p>

A fragrance\u2019s safety level is not dependent on whether it comes from nature or a lab. It is also contingent on the concentration of the specific VOC in the air.\u00a0 To ensure fragrances (VOCs) from candles are safe, fragrance formulas are reviewed against the safety standards established by the International Fragrance Association (IFRA).\u00a0 Each ingredient in the fragrance and the finished product is required to meet the specifications set down by IFRA to be compliant with the standard. If the fragrance and product meet the standard, then the fragrance VOCs in that particular product are considered safe for human use.<\/p>

The federal government, along with California and several other states, have established VOC regulations for consumer products such as candles and air fresheners.\u00a0 They limit the concentration of VOCs in these and many other consumer products. These regulations have a very specific definition of what they consider a VOC. VOCs that do not evaporate easily are not considered VOCs under these regulations, but they are still volatile compounds.\u00a0 These VOC limits on consumer products are not based on any health concerns about the VOCs themselves. Instead, the limits exist to minimize the interaction between VOCs and other chemicals in our atmosphere.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Although millions of Americans regularly use scented candles without any negative effects, it is always possible that a particular fragrance might trigger a negative reaction in a very small percentage of sensitive individuals. Individuals with known sensitivities to specific fragrances may want to avoid candles of those scents. In addition, consumers should remember to burn all candles, whether scented or unscented, in a well-ventilated area.\u00a0\u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

No. Lead wicks have been officially banned in the United States since 2003, and before then they were primarily limited to inexpensive imported candles. NCA members voluntarily agreed to not use lead wicks in 1974, and long supported the elimination of lead wick use.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The oils found in certain fragrances may slightly increase the small amount of soot produced by a candle, but wick length and flame disturbance are the primary factors that impact sooting in a properly-formulated candle.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

No. The minuscule amount of soot produced by a candle is the natural byproduct of incomplete combustion. Candle soot is composed primarily of elemental carbon particles, and is similar to the soot given off by kitchen toasters and cooking oils. These everyday household sources of soot are not considered a health concern, and are chemically different from the soot formed by the burning of diesel fuel, coal, gasoline, etc.<\/p>

The production of candle soot can also be minimized in the following ways:\u00a0 Trim the wick to \u00bc inch before every use to promote proper flame height, place the candle away from drafty areas to avoid flame flickering, and ensure that the wax pool is free of debris.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

When you light a candle, the heat of the flame melts the wax near the wick. This melted or liquid wax is then drawn up into the wick by capillary action. The flame\u2019s heat vaporizes the liquid wax to produce water vapor and carbon dioxide (the same byproducts that humans produce when exhaling).<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

No. All types of quality candle waxes have been shown to burn cleanly, safely and in the same manner.

Although modern technology has introduced greater efficiencies and quality control in candle-making, most candles are made through the timeless process of a wick into wax, which is then molded, dipped, extruded, pressed, rolled, drawn or filled into a desired shape and size.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Metal-core wicks are sometimes used in container candles and votives to keep the wick upright when the surrounding wax liquefies during burning.

A well-made candle will create virtually no smoke when burning properly. Consumers often incorrectly believe their candles are sooting because of the wax type, fragrance, colorants or additives used in the candle\u2019s formulation, but sooting is primarily due to flame and combustion disturbances. If the wick becomes too long, or an air current disturbs the flame\u2019s teardrop shape, small amounts of unburned carbon particles (soot) will escape from the flame as a visible wisp of smoke. Any candle will soot if the flame is disturbed.<\/p>

To avoid this, always trim the wick to \u00bc inch before every use and be sure to place candles away from drafts, vents or air currents. If a candle continually flickers or smokes, it is not burning properly and should be extinguished. Allow the candle to cool, trim the wick, make sure the area is draft free, then re-light.\u00a0<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

Maximum burn times vary from candle to candle, so it is important to follow the manufacturer\u2019s instructions. Always extinguish a candle if the flame gets too close to the candle holder or container. For a margin of safety, discontinue burning a candle when 2 inches of wax remains (\u00bd inch if a container candle or jar candle).<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t
