What You'll Learn
Candles with essential oils can kill bacteria
Candles are a popular way to create a cosy atmosphere and fill your home with your favourite scents. However, it's important to be aware of the potential impact that candles can have on indoor air quality. Most candles are made from paraffin wax, which is derived from petroleum and releases toxic chemicals such as benzene and toluene when burned. These toxins are known carcinogens, posing potential health risks to you and your loved ones.
Fortunately, there's a growing trend of candles made with natural ingredients, including essential oils. These candles offer an appealing alternative to traditional paraffin wax candles. Not only do they fill your home with delightful fragrances, but they also provide antibacterial benefits. Researchers have found that certain essential oils, such as eucalyptus, orange, thyme, and palmarosa, exhibit antibacterial properties when added to candles.
In a study conducted by researchers from the University of Southampton, candles containing essential oils were tested against E. coli and staph bacteria. The results were impressive, with the essential oil candles proving to be almost 100% effective in eliminating the bacteria. The study also compared the effectiveness of different essential oils, finding that orange oil worked better against E. coli, while palmarosa was more potent against staph bacteria.
The antibacterial properties of essential oil candles are believed to arise from the reaction between the oils, ions in the wick, and oxygen. This reaction gives the candles their bacteria-fighting power. However, it's important to note that candles alone are not a substitute for regular cleaning and disinfection. While they can help reduce bacteria in the air and on surfaces, they won't eliminate dirt or grease.
When choosing candles with essential oils, it's crucial to be cautious. Some manufacturers may use only a minimal amount of essential oil, filling the rest with synthetic chemicals. Always opt for candles made with 100% essential oils or choose unscented options. Additionally, if you have pets, be sure to check if the specific essential oil is safe for them, as some oils like cinnamon and peppermint can be toxic to animals.

Paraffin wax candles create carcinogens
Candles create a soothing ambiance and fill your home with lovely scents. However, they might be affecting the air quality in your home. Most candles are made from paraffin wax, which is derived from petroleum, coal, or shale oil. This means that burning paraffin wax releases toxic chemicals, such as benzene and toluene, which are known carcinogens. These toxins are the same as those found in diesel fuel fumes and can cause serious health issues.
Benzene is a colorless liquid derived from natural gas and crude oil, and it is used as a solvent. Toluene is also a colorless liquid that occurs naturally in crude oil, and it is emitted from gasoline fumes, vehicle exhausts, and cigarette smoke. In addition to these toxic chemicals, paraffin wax can also contain synthetic fragrances with undisclosed chemicals, some of which may be linked to reproductive issues.
The smoke from burning paraffin wax candles carries these toxic chemicals and pollutes the air you breathe. This can be especially harmful to individuals with existing health problems, children, the elderly, and pets. The Department of California's Hazard Communication Standard/OSHA regulation states that toluene can damage the central nervous system, resulting in headaches, nausea, dizziness, and insomnia. Even mild exposure to toluene can lead to frequent headaches, nausea, and fatigue.
To minimize the impact of paraffin wax candles on your indoor air quality, it is recommended to burn candles only in well-ventilated areas and to trim the wax to reduce smoke and soot production. However, switching to candles made from beeswax, soy wax, or other plant-based waxes is a healthier option, as these alternatives burn slowly, produce less soot, and do not release toxic chemicals.
While some sources question the validity of certain studies on the toxicity of paraffin wax, it is important to consider taking precautions or choosing healthier alternatives to ensure the safety and well-being of yourself and your loved ones.

Soy candles can 'smoke out' bacteria'
Candles are commonly made from paraffin wax, a petroleum byproduct. Burning paraffin wax releases toxins such as benzene and toluene, which are known carcinogens. The wicks of some candles may also contain lead, which can be dangerous if the lead concentration exceeds safe levels.
As a result of the potential dangers associated with paraffin wax candles, many people opt for candles made from alternative materials, such as beeswax, soy wax, or palm wax. Soy candles, in particular, have gained popularity due to their eco-friendly and non-toxic properties.
Soy candles are made from EcoSoya wax, which is free from genetically modified materials and is considered safe under the Food, Drug, and Cosmetic Act. They produce less soot and toxic chemicals than paraffin wax candles, making them a healthier alternative.
Additionally, soy candles can be infused with essential oils, such as eucalyptus, orange, and thyme, which have been shown to have antibacterial properties. Researchers have found that these essential oils can destroy bacteria such as Escherichia Coli and Staphylococcus Aureus, making soy candles an effective way to improve indoor air quality and hygiene.
However, it is important to note that candle smoke, even from soy candles, can still contain pollutants. Therefore, it is recommended to minimise smoke inhalation by trimming the wick, avoiding burning candles in drafty areas, and ventilating rooms after extinguishing candles.

Beeswax candles are natural and non-toxic
While candles can be a great way to create a soothing atmosphere, it's important to be aware of the potential dangers they pose to air quality. Most candles are made from paraffin wax, which is derived from petroleum. Burning paraffin wax releases toxins such as benzene and toluene, which are known carcinogens. Additionally, the fragrance component of candles may contain undisclosed synthetic chemicals, further contributing to indoor air pollution.
However, not all candles are created equal. Beeswax candles, for example, are a natural and non-toxic alternative to traditional paraffin wax candles. Beeswax candles are made from beeswax, which is a natural substance produced by honeybees. Unlike paraffin wax, beeswax burns slowly and evenly, producing little to no smoke or soot. This makes it a cleaner option for your indoor air quality.
Beeswax is also a non-toxic substance, meaning it won't release harmful chemicals into the air as it burns. This makes beeswax candles a safer option for individuals with respiratory issues or allergies. In addition, beeswax has a high melting point, which means that beeswax candles have a longer burn time compared to other types of candles. This not only makes them more cost-effective but also reduces the amount of waste generated over time.
Furthermore, beeswax candles often feature natural wicks made from materials such as cotton or paper, avoiding the use of harmful lead wicks. Some beeswax candles also incorporate essential oils, adding a pleasant fragrance to the candle while also offering potential aromatherapy benefits. It's important to note that not all essential oils are safe for everyone, so it's always a good idea to research the specific oils used in your candles, especially if you have pets or individuals with sensitivities in your household.
Overall, beeswax candles are a natural and non-toxic option for those looking to enjoy the ambiance of candles without compromising their indoor air quality or their health. With their slow burn, clean light, and potential aromatherapy benefits, beeswax candles offer a safer and more sustainable alternative to traditional paraffin wax candles.

Lead wicks can be dangerous
Candles can be a great way to improve the ambiance of a room and fill it with a pleasant scent. However, it's important to be aware of the potential dangers that candles can pose, especially those with lead wicks.
In 2003, the U.S. Consumer Product Safety Commission (CPSC) banned the manufacturing, importing, and selling of candles with lead-cored wicks due to concerns about lead poisoning, particularly in young children. Lead wicks had already been voluntarily removed by manufacturers in the 1970s, but a small percentage of candles continued to contain them. The ban was intended to protect consumers from the potential health hazards of lead exposure, which can be released into the air and deposited on surfaces in your home.
Lead is a toxic substance that can have serious health effects, even at low levels of exposure. Inhalation of lead particles can affect the central nervous system and lead to symptoms such as headaches, nausea, and irritability. Prolonged exposure to lead can result in more severe health issues, including damage to the brain and kidneys, and interference with the production of red blood cells.
To avoid the risks associated with lead wicks, it's important to be vigilant when purchasing candles. Firstly, look for candles with natural wicks made from materials like cotton, wood, or paper. These wicks are safer alternatives that won't release toxic substances into the air. You can also opt for candles made from natural waxes like beeswax, soy, or palm oil, which tend to be free of toxic chemicals.
Additionally, you can perform a simple test to check for lead wicks. Known as the "No-Lead Test," you simply rub the tip of an unburnt wick on a piece of white paper. If it leaves a light grey mark, similar to a pencil, the wick contains lead. If you already own candles and discover they have lead wicks, it's recommended to dispose of them safely and avoid burning them.
