Candles are a common household item, often used to create a relaxing atmosphere or to fill a room with pleasant scents. However, there has been concern over the potential health risks associated with burning candles, particularly those containing lead. Lead was previously used in candle wicks to make them stand up straighter and improve the candle's burn. While lead-cored wicks are now banned in several countries, there is still a risk of exposure to lead from older candles or non-compliant products. This paragraph will explore the topic of lead in candles, including the dangers of lead exposure, the steps taken to regulate lead-cored wicks, and the alternatives available to consumers.
Do candles contain lead?
| Characteristics | Values |
|---|---|
| Do candles contain lead? | Candle wicks in the United States don't currently contain lead. In 2003, the U.S. Consumer Product Safety Commission (CPSC) banned the sale and manufacture of candles with lead wicks. |
| Why was lead used in candle wicks? | Lead was used in candle wicks as a stiffening agent to keep the wick straight and out of the molten wax. |
| What are the dangers of lead in candle wicks? | Burning a candle with a lead-core wick releases five times the amount of lead considered hazardous for children and exceeds EPA pollution standards for outdoor air. Lead poisoning in children is associated with behavioral problems, learning disabilities, hearing problems, growth retardation, and numerous health problems. |
| How to identify candles with lead wicks? | Candles with lead wicks can be identified by a silvery or dark lead core in the fabric of the wick. Alternatively, you can rub the tip of the wick of an unburnt candle on a piece of paper, and if it leaves a gray mark, like a pencil, the wick contains a lead core. |
| What are some safe alternatives to lead-cored wicks? | Safe alternatives to lead-cored wicks include zinc, synthetic fibers, cotton, and paper. Most candle manufacturers now use these alternative materials in their wicks. |
| What are some non-toxic candle alternatives? | If you're looking for non-toxic candle alternatives, you can try beeswax candles, soy candles, or candles made from other plant-based waxes. |
| How to minimize the risks of burning candles? | To minimize the risks of burning candles, it is recommended to burn them for shorter periods, ensure proper ventilation, and choose candles made from natural sources, such as palm stearin, which produce less soot and release less dangerous chemicals. |

What You'll Learn
Candles with lead wicks have been banned in the US since 2003
The CPSC determined that candles with lead-cored wicks could present a lead poisoning hazard, especially to young children. Lead poisoning in children is associated with behavioural problems, learning disabilities, hearing problems, and growth retardation. Even exposure to small amounts of lead can contribute to the overall level of lead in the blood. Burning a candle with a lead-core wick releases five times the amount of lead considered hazardous for children and exceeds EPA pollution standards for outdoor air.
Candles with lead wicks were once popular because lead helped the wicks stand up straighter, and the candle burned better. However, the lead would then vaporize into the air, where it could be inhaled. Burning a candle releases chemicals, particulate matter, and pollutants that may be harmful to human health. Research has shown that burning multiple candles can elevate the air lead concentration above permissible exposure limits.
If you have a candle from before 2003, you can test for a lead wick by rubbing the tip of the wick on a piece of paper. If it leaves a grey mark, like a pencil, the wick contains lead. If you suspect a candle you have burned might have a lead wick, it is recommended to throw it out.

Lead in candle wicks can cause lead poisoning
In response to the health risks posed by lead-cored wicks, the Consumer Product Safety Commission (CPSC) in the United States banned the manufacturing, importing, and selling of candles with lead wicks in 2003. This ban came after a 30-year period during which the candle industry was expected to voluntarily regulate lead usage in wicks. Despite this voluntary agreement, a small percentage of candles sold in recent years still contained lead-cored wicks.
The presence of lead in candle wicks was due to its function as a stiffening agent, helping the wick remain upright and improving the candle's burn. However, as lead vaporizes into the air, it poses a significant health hazard, especially in enclosed spaces. Burning multiple candles with lead-cored wicks can exceed permissible exposure limits, increasing the risk of lead poisoning.
To identify candles with lead wicks, one can look for a silvery or dark lead core in the fabric of the wick. Additionally, rubbing the tip of the wick on a piece of paper will leave a grey mark if it contains lead. It is recommended to avoid using candles with lead wicks and to opt for candles made from natural sources, such as beeswax, soy wax, or palm stearin, which produce less soot and release fewer dangerous chemicals. Proper ventilation when burning candles is also advised to minimize potential health risks.

Candles without lead wicks include tapers, beeswax, and soy candles
Lead was commonly used in candle wicks to make them stand up straight and burn better. However, when burned, candles with lead-cored wicks can release unsafe levels of lead into the air, which can be inhaled and cause lead poisoning. Lead poisoning is especially dangerous for young children and can cause behavioural problems, learning disabilities, hearing problems, and growth retardation.
Due to these health concerns, there is now a ban on the manufacturing, importing, and selling of candles with lead wicks. This ban was implemented in 2003 by the U.S. Consumer Product Safety Commission (CPSC) and applies to all domestic and imported candles. As a result, most candles today do not contain lead wicks. Candles without lead wicks include tapers, beeswax, and soy candles.
Tapers, commonly used as dinner candles, use cotton wicks and do not contain lead. Beeswax candles are also a non-toxic alternative to traditional candles. Soy candles are another option made from soy wax, which is derived from soybeans. These candles are natural and minimize the amount of particulate matter released into the air.
If you are unsure whether a candle contains a lead wick, you can rub the tip of the wick on a piece of paper. If it leaves a grey mark, similar to a pencil mark, the wick contains lead. It is recommended to dispose of such candles immediately.

How to identify candles with lead wicks
Lead was added to candle wicks to make them stand up straighter and improve the candle's burn. However, this lead would then vaporize into the air and could be inhaled, causing lead poisoning, especially in children. Lead poisoning in children is associated with behavioural problems, learning disabilities, hearing problems, and growth retardation.
In 2003, the US Consumer Product Safety Commission (CPSC) banned the sale and manufacture of candles with lead wicks, as well as the import of lead-containing candles from other countries. This ban came after a 30-year period during which the candle industry was supposed to voluntarily "self-regulate" the use of lead in wicks.
Despite this ban, you may still have candles with lead wicks in your home, especially if they are old. To identify candles with lead wicks, you can try the following methods:
- Look for a silvery or dark lead core in the fabric of the wick.
- Rub the tip of the wick of an unburnt candle on a piece of paper. If it leaves a grey mark, like a pencil, the wick contains lead.
If you suspect a candle may have a lead wick, it is best to throw it out. To reduce your exposure to particulate matter and potentially harmful chemicals, it is recommended to burn candles for shorter periods and to ventilate your room after extinguishing them. Natural candles, such as those made from palm stearin, beeswax, or soy wax, release fewer pollutants and are healthier options.

Burning candles releases chemicals, but proper use minimises health risks
Candles are a popular way to create a soothing atmosphere and fill a room with delightful scents. However, there have been concerns about the potential health risks associated with burning candles, particularly those with lead-core wicks. The good news is that candles with lead-core wicks have been banned since 2003, and most manufacturers stopped using lead in their candles much earlier, in the 1970s.
Lead-core wicks and their dangers
Lead was historically used in candle wicks to make them stand straighter and improve the candle's burn. However, when a candle with a lead-core wick is burned, it can release lead particles into the air, which can then be inhaled. Lead accumulation in the body can lead to lead poisoning, which is particularly dangerous for young children and can cause behavioural problems, learning disabilities, hearing issues, and growth retardation.
Current regulations and alternatives
In 2003, the US Consumer Product Safety Commission (CPSC) banned the sale, manufacture, and import of candles with lead-core wicks. This ban applies to all domestic and imported candles. As a result, candles manufactured and sold today do not contain lead-core wicks. Instead, candle manufacturers use safe alternatives such as zinc, synthetic fibres, cotton, and paper for wicks.
Minimising health risks
While burning candles can release chemicals, proper use can minimise potential health risks. The European Candle Association offers the following advice for handling candles:
- Avoid burning candles in drafty areas.
- Trim the wick if it exceeds 5 to 10 millimetres in length.
- Extinguish the candle by using a candle snuffer or dipping the wick into wax instead of blowing it out.
- Ensure proper ventilation during and after burning a candle.
Additionally, it is recommended to reduce the amount of time candles are burned. While there is no definitive rule, it is generally advised not to burn them continuously for extended periods.
Non-toxic alternatives
If you are concerned about the potential health risks of burning candles, there are non-toxic alternatives available, such as beeswax, soy wax, or other plant-based candles. Essential oils can also be used to create aromatherapy benefits and pleasant scents without the worry of releasing harmful pollutants.
