Cheap candles have been the subject of scrutiny in recent years, with many people wondering if they are toxic. The short answer is: it depends. While candles today no longer use lead-core wicks, the wax they are made of and the fragrances they emit may be harmful. Paraffin wax, for example, releases toxic compounds such as acetone, benzene, and toluene when burnt. These compounds are known carcinogens and are associated with asthma and allergies. However, soy wax and beeswax candles are often touted as non-toxic alternatives, though the former's link to the soybean industry has raised environmental concerns. Ultimately, while most candles adhere to safety standards, scented candles can cause issues for people with asthma or allergies.
Are cheap candles toxic?
| Characteristics | Values |
|---|---|
| Toxic compounds | Paraffin wax candles release toxic compounds into the air, including acetone, benzene, and toluene, which are known carcinogens. |
| Health risks | Exposure to these compounds can cause eye irritation, a dry mouth or throat, headaches, skin rashes, shortness of breath, and dizziness. |
| Wick safety | Lead wicks were officially outlawed in the US in 2003. However, older candles manufactured before this date may still contain lead. |
| Fragrance safety | Natural fragrances derived from essential oils are generally considered safe. Synthetic fragrances, on the other hand, are typically made from petroleum-based chemicals and can release toxic particles when burned. |
| Alternative wax options | Soy wax, beeswax, and vegetable-based waxes are marketed as non-toxic alternatives to paraffin wax, but their effectiveness in reducing toxicity is debated. |
| Scented candle considerations | While scented candles conform to safety standards, they can cause problems for individuals with asthma, allergies, or other respiratory issues. |

Cheap candles may contain paraffin wax, which releases toxic compounds when burnt
A 2009 study by South Carolina State University found a link between paraffin wax candles and harmful fumes, connected to lung cancer and asthma. The study also showed that paraffin candles produce soot, which can be inhaled and reach the deepest parts of the lungs, the lower respiratory tract, and the alveoli. Paraffin candles are cheaper to produce than other types of wax candles, which is why they are so widely used.
However, there are alternatives to paraffin wax candles. Soy wax candles, for example, do not contain toxic pollutants and produce significantly less soot. They burn at a lower temperature and last longer. Beeswax candles are another option, which can help clean the air as they release negative ions, clearing pollen, mold spores, bacteria, and viruses.
It is worth noting that scented candles, whether the scent is natural or synthetic, can cause problems for people with asthma or other respiratory issues, as well as allergies. Natural fragrances are derived from essential oils, while synthetic fragrances are usually made from petroleum-based chemicals.

Lead wicks were outlawed in 2003, but older candles may still contain them
Candles have been the subject of some controversy, with many people asking if they are toxic. While the fragrances used in scented candles are typically safe, wicks have been a major concern. In the past, candle wicks were made with lead to make them stiffer. However, lead wicks were officially outlawed by the United States Consumer Product Safety Commission in 2003.
Despite this, older candles may still contain lead wicks, and it is important to exercise caution when using or purchasing candles made before 2003. Lead wicks can release harmful and carcinogenic chemicals into the air when lit. To check if a candle contains lead, rub a piece of white paper against the unburnt wick. If the wick leaves a mark that resembles pencil, it contains lead.
It is worth noting that members of the National Candle Association, including major brands such as Yankee Candle and Bath and Body Works, voluntarily agreed to stop using lead wicks in 1974. Therefore, even candles manufactured before 2003 may not contain lead. However, it is always better to be cautious, especially if you have concerns about the potential presence of lead in older candles.
Today, candle wicks are typically made from cotton or paper, which are safe alternatives. However, it is important to be aware of the type of wax used in candles, as some types of wax, such as paraffin wax, can release toxic compounds when burnt. Soy wax and beeswax are considered safer alternatives to paraffin wax, although they may not be suitable for vegans. Overall, while lead wicks have been outlawed, it is important to be vigilant, especially when using older candles that may predate the 2003 ban.

Scented candles can cause issues for people with asthma or allergies
While candles are no longer made with lead-core wicks, and their wax is non-toxic, scented candles can cause issues for people with asthma or allergies. Burning paraffin wax releases volatile organic compounds (VOCs) into the air, including acetone, benzene, and toluene, which are known to be carcinogenic and asthma and allergy triggers. These toxic compounds are also found in the exhaust from diesel car fumes. Symptoms caused by exposure to VOCs can include eye irritation, a dry mouth or throat, headaches, skin rashes, shortness of breath, and dizziness.
One study at South Carolina State University found that paraffin wax candles give off harmful fumes linked to lung cancer and asthma. Paraffin candles also produce soot, which can be inhaled and find its way into the deepest depths of the lungs, the lower respiratory tract, and alveoli. The chemicals released from paraffin candles can be especially harmful to people with respiratory conditions, such as asthma.
Natural fragrances in scented candles are created with essential oils derived from plants and flowers, while synthetic fragrances are man-made, usually from petroleum-based chemicals. Synthetic fragrances expose you to dangerous toxins, whereas essential oils are safe to inhale, as they "re-modulate themselves and work in a friendly way" once inhaled, according to Petits Rituels founder, Nathalie Allard.
Scented candles can cause problems for people with asthma or other respiratory issues, as well as trigger allergic reactions, with symptoms like sneezing, a runny nose, or blocked sinuses. If you are concerned about using scented candles but still want the candlelight ambiance, battery-powered or electric flameless candles are recommended.

Soy wax candles are a non-toxic alternative to paraffin wax
Candles are a popular way to fill your home with fragrance and create a cosy atmosphere. However, some candles may be damaging to both your health and the environment. One of the main concerns is the use of lead wicks, which can release harmful and carcinogenic chemicals into your home. Fortunately, lead wicks were outlawed in 2003, so this is no longer a concern for most candle buyers.
Another concern is the type of wax used in candles. Paraffin wax, a common ingredient in candles, releases toxic compounds into the air when burnt, including acetone, benzene, and toluene, all known carcinogens. Paraffin candles also produce soot, which can be inhaled and find its way into the deepest depths of the lungs, the lower respiratory tract, and alveoli. While the amount of these chemicals released is minimal, and most people are not affected, it is still a concern for those with respiratory conditions such as asthma.
While soy wax is a great alternative to paraffin wax, it is important to note that it is not without its drawbacks. Soy wax is generally more expensive than paraffin wax and has a shorter burning time. It also doesn't hold scent as well as paraffin wax, so you may not get the same level of fragrance. Additionally, over 90% of soybean crops in the United States are genetically modified and grown using pesticides, which may be a concern for some consumers.
Overall, if you are looking for a clean-burning, eco-friendly, and non-toxic alternative to paraffin wax, soy wax is a great option. However, it is important to consider your priorities when choosing a candle, as soy wax may not be the best choice for everyone.

Synthetic fragrances are usually made from petroleum-based chemicals
Cheap candles, like any other candle, can be made from a variety of waxes, including paraffin, soy, and beeswax. Paraffin wax candles are the most common type of candle and are made from petroleum, a non-renewable resource. When burned, paraffin wax releases toxic compounds into the air, including acetone, benzene, and toluene, all known carcinogens.
A 1986 report by the National Academy of Sciences found that 95% of the chemicals used in synthetic fragrances are derived from petroleum or crude oil. This includes benzene derivatives, which are carcinogenic. In addition to the health risks, synthetic fragrances are also a concern because they are not environmentally friendly. They are derived from non-renewable resources and can decrease indoor air quality.
It's important to note that not all synthetic fragrances are harmful. Many fragrances contain a mixture of synthetic and natural ingredients, and some synthetic fragrances can be made without toxins. Synthetic fragrances have benefits, including improved scent performance, flexibility, affordability, and environmental sustainability.
When it comes to the safety of candles, the wicks have also been a cause for concern. In the past, candle wicks were made with lead, which can release harmful and carcinogenic chemicals when burned. However, lead wicks were outlawed in the United States in 2003, and most candle companies no longer use lead wicks.
Overall, while cheap candles made with paraffin wax and synthetic fragrances may release toxic compounds into the air, the potential health risks are relatively low for most people. However, for individuals with asthma or allergies, the chemicals released from these candles can be especially harmful. It's important to be aware of the potential risks and take steps to minimize exposure if necessary.
