What You'll Learn
Paraffin wax is derived from petroleum, coal, or shale oil
Paraffin wax, also known as petroleum wax, is a soft, colourless, odourless, and flavourless waxy solid derived from petroleum, coal, or shale oil. It consists of a mixture of hydrocarbon molecules containing between 20 and 40 carbon atoms. Paraffin wax was first created by German chemist Carl Reichenbach in 1830. The process involved efficiently separating and refining waxy substances naturally occurring in petroleum. This marked a significant advancement in candle-making technology, as paraffin wax burned more cleanly and consistently than tallow-based candles and was cheaper to produce.
The process of creating paraffin wax starts with a multi-step process known as fractional distillation, where petroleum is separated into different components called fractions. The feedstock for paraffin is slack wax, a mixture of oil and wax that is a byproduct of lubricating oil refining. The first step is to remove the oil (de-oiling or de-waxing) from the slack wax through crystallization. Typically, the slack wax is heated, mixed with a solvent, and then cooled. As it cools, the wax crystallizes, separating it from the oil. This mixture is then filtered into solid and liquid streams. After distillation, the resulting products are called "product wax" or "press wax" and "foots oil". The lower the percentage of oil in the wax, the more refined it is considered.
Paraffin wax has a wide range of applications, including lubrication, electrical insulation, crayons, cosmetics, skincare, and candles. It is commonly used in candle-making due to its low cost and consistent burn. However, concerns have been raised about the potential health risks associated with burning paraffin wax candles. Research has shown that burning paraffin wax releases potentially harmful chemicals such as volatile organic compounds (VOCs) and phthalates. Exposure to these chemicals has been linked to adverse health effects, including headaches, shortness of breath, and coughing.
Additionally, paraffin wax has been found to contain known carcinogens, including benzene and toluene. These toxic chemicals are released into the air when paraffin wax candles are burned, potentially posing a health risk to those exposed. While some argue that the amount of toxins released is not significant enough to cause harm, others prefer to use alternative waxes, such as soy wax, beeswax, or plant-based waxes, which are considered safer and more sustainable options.
Paraffin wax is derived from petroleum, which is a byproduct of the gasoline production process. While paraffin wax has a range of practical uses, its connection to the petroleum industry has led to concerns about its environmental impact. Petroleum and its byproducts have had a negative impact on the planet, and some view paraffin wax as contributing to these environmental concerns. However, others argue that using petroleum byproducts can be seen as a way to make the most of already-extracted oil, contributing to sustainability efforts.

Burning paraffin wax releases carbon dioxide and harmful substances
Research has shown that burning paraffin wax releases potentially harmful chemicals, including volatile organic compounds (VOCs) and phthalates. Exposure to these chemicals has been linked to adverse health effects, including headaches, shortness of breath, and coughing. In addition to benzene and toluene, formaldehyde is another harmful substance released during the burning of paraffin wax. Formaldehyde is a known carcinogen and has been linked to an increased risk of developing urothelial cancer.
The release of these harmful substances poses subtle threats to human health, and prolonged exposure to particulate matter from candle smoke may lead to heart and lung problems. However, it is important to note that the impact of candle smoke on health may be minimal compared to other sources of pollution encountered daily. Nonetheless, it is advisable to minimise exposure to any type of smoke.
To reduce the potential health risks associated with paraffin wax candles, consumers can opt for candles made from natural materials such as beeswax or soy wax. These alternatives are considered safer and more sustainable, as they are derived from natural sources and do not contain the same toxic chemicals as paraffin wax. Soy wax, in particular, has a stronger fragrance and a lower melting point, ensuring that the scent profile of the candle is not compromised.

Paraffin wax candles may cause skin irritation
Paraffin wax candles have been found to contain known carcinogens, such as benzene, and emit toxic chemicals when burned. These toxins can be released into the air and inhaled, potentially causing health issues. While the wax itself is not directly applied to the skin, the fumes and resulting air pollution can cause skin irritation and other dermatological issues.
Paraffin wax is derived from petroleum, coal, or shale oil, and during the refining process, it is often bleached with dioxin and texturized with acrolyn, a known carcinogen. These additional chemicals can contribute to the release of toxic fumes when the paraffin wax is burned. The American Cancer Society specifically highlights benzene as a known carcinogen, with studies showing increased rates of leukemia in workers exposed to high levels of this chemical.
The potential health risks associated with paraffin wax candles extend beyond cancer concerns. The emission of volatile organic compounds (VOCs), phthalates, and particulate matter can lead to short-term symptoms such as headaches, nausea, dizziness, and fatigue. These symptoms are indicative of central nervous system disruption, as toluene, another chemical present in paraffin wax, can induce DNA strand breakdowns.
The skin, as the body's largest organ, is susceptible to these toxic fumes. While the irritation may not be directly applied like a topical product, the skin can absorb and react to the chemicals in the air. This can manifest as itching, exacerbation of existing skin conditions, or other forms of dermatological inflammation.
The extent of skin irritation caused by paraffin wax candles may vary among individuals, and other factors, such as the quality of the paraffin and the duration of exposure, also play a role. However, given the potential risks, it is advisable to opt for natural, sustainable alternatives, such as coconut, soy, or beeswax candles, which are free of harmful toxins and provide a cleaner burning experience.

Soy candles produce less soot and toxic chemicals
Paraffin wax is a common material used in candle-making due to its affordability and accessibility. However, concerns have been raised about the potential health risks associated with burning paraffin candles. Research indicates that burning paraffin wax releases potentially harmful chemicals, including volatile organic compounds (VOCs) and phthalates. Extended exposure to particulate matter released by burning paraffin candles may contribute to heart and lung problems. Additionally, paraffin wax, derived from petroleum, coal, or shale oil, contains known carcinogens like benzene and toluene. These toxic chemicals can induce DNA strand breakdowns and negatively affect the central nervous system.
As a result, consumers are increasingly seeking healthier alternatives, and soy candles have emerged as a popular option. Soy candles produce less soot and toxic chemicals than paraffin candles, making them a healthier choice. Soy wax is free from parabens, phthalates, and paraffins, and it burns without emitting petro-carbon soot, a byproduct of incomplete combustion of petroleum-based fuels. This makes soy candles a non-toxic, sustainable, and environmentally friendly alternative.
The benefits of soy candles extend beyond their reduced toxicity. Soy wax is derived from soybeans, a widely available crop in the United States, constituting 34% of global soybean production. However, it's important to consider the potential drawbacks of soy candles. Soy crops have been linked to deforestation, straining ecosystems, and impacting the livelihood of small farmers.
While soy candles offer a cleaner burning experience, it's still advisable to minimise smoke inhalation of any kind. Proper candle handling is crucial, including avoiding drafty areas, regularly trimming wicks, using a candle snuffer or dipping the wick in wax instead of blowing it out, and ventilating the room after extinguishing the candle.
In conclusion, soy candles are a healthier alternative to traditional paraffin candles due to their reduced soot and toxic chemical emissions. However, it is always recommended to practise safe candle usage and be mindful of potential environmental impacts associated with specific types of candle wax.

Burning paraffin wax releases volatile organic compounds (VOCs)
Research has shown that burning paraffin wax can release toxic VOCs, including known carcinogens. These VOCs have been linked to various health issues, including headaches, shortness of breath, coughing, irritation to the eyes, nose or throat, nausea, and even potential damage to the liver, kidneys, and central nervous system.
A 2005 study by the University of South Florida found that paraffin wax candles emit low levels of benzene even when unlit. Another study from South Carolina State University found that melting paraffin wax candles released toxic toluene and benzene, while soy candles did not. Toluene is a colourless, water-insoluble liquid that is naturally found in crude oil and emitted from gasoline fumes and vehicle exhausts. It is also used as a solvent in paint products, nail polish, lacquers, glue, and adhesives. Benzene is also a colourless liquid derived from natural gas and crude oil and is used as a solvent.
The potential health risks associated with exposure to VOCs from burning paraffin wax have led some people to seek alternative candle options, such as those made from beeswax, soy wax, or other plant-based waxes. These plant-based waxes burn at lower temperatures, last longer, and are derived from renewable sources. Soy candles, in particular, have been found to produce less soot and toxic chemicals than paraffin candles.
While the smoke from burning candles in a well-ventilated area is unlikely to significantly affect health compared to other sources of pollution, it is generally recommended to minimise exposure to any type of smoke. Experts advise ventilating rooms after burning candles and following candle care guidelines, such as trimming the wick and avoiding burning candles in drafty areas.
