Paraffin wax is a by-product of the oil industry, extracted from crude oil
The process of making paraffin wax involves heating slack wax, which is a combination of oil and wax and a by-product of lubricating oil refinement. The wax is then mixed with a solvent such as ketone and cooled. As it cools, the wax crystallizes out of the solution, leaving only oil. This mixture is then filtered into two streams: solid (wax plus some solvent) and liquid (oil and solvent). The solvent is then recovered through distillation, resulting in "product wax" or "press wax" and "foots oil". The product wax may undergo further processing to remove colours and odours, and it is then supplied in either liquid or solid form.
The use of paraffin wax in candles has been a topic of debate due to concerns about its potential toxicity and environmental impact. Some studies have suggested that burning paraffin wax candles release harmful fumes linked to asthma and lung cancer. However, the European Candle Association and the National Candle Association have defended the use of paraffin wax, citing a 2007 study that found no production of benzene in any of the candle waxes tested, including paraffin wax.
Despite the debate, paraffin wax remains a popular choice for candle-making due to its ability to produce a better scent throw and its clean-burning qualities. It is also used in various other applications, including lubrication, electrical insulation, crayons, cosmetics, and food additives.
In conclusion, paraffin wax is a by-product of the oil industry, extracted from crude oil through a refining process. It has a range of practical uses, with candle-making being a prominent application. While there are ongoing discussions about its potential health and environmental impacts, paraffin wax continues to be widely used due to its desirable characteristics.

It is widely used in candles, cosmetics, and food additives
Paraffin wax is a widely used material, especially in candles, cosmetics, and food additives. It is a soft, colourless, or white solid derived from petroleum, coal, or oil shale. It consists of a mixture of hydrocarbon molecules containing 20 to 40 carbon atoms. Paraffin wax is solid at room temperature and begins to melt at temperatures above approximately 37°C (99°F). Its high boiling point of over 370°C (698°F) makes it ideal for candles.
Paraffin wax has been used in candle-making for centuries, and today, it is estimated that 95% of candles on the market use paraffin wax. It is a popular choice due to its affordability, consistent burn, ability to hold fragrance and colour, and attractive finish. Paraffin wax candles are also known for their strong scent throw and ability to hold a large amount of fragrance without affecting burn quality, making them ideal for aromatherapy. However, there are concerns about the potential health risks of burning paraffin candles, as studies have shown that they can release harmful chemicals, such as benzene, toluene, and formaldehyde, into the air.
In addition to candles, paraffin wax is used in cosmetics and skincare products, such as Vaseline, where it acts as a moisturiser. It is also used as a food additive and coating in various products, including candy, chocolates, chewing gum, and hard cheeses like Edam. Food-grade paraffin wax is non-digestible and passes through the body without being broken down. It is important to note that while paraffin wax has many uses, it is a non-renewable resource and there are ongoing debates about its potential toxicity and environmental impact.
The use of paraffin wax in candles, cosmetics, and food additives offers both advantages and considerations. While it provides functional and aesthetic benefits, such as improved scent throw and consistent burning, there are health and environmental concerns associated with its use. As a result, alternative options, such as soy and coconut wax, are also gaining popularity alongside paraffin wax in these applications.

Paraffin candles have a better scent throw than other waxes
The use of paraffin wax in candles is a highly debated topic. Paraffin is a by-product of the oil industry, derived from crude oil during the refining process. It is a type of petroleum wax, which is a broad category that includes several types of wax products derived from crude oil.
One of the benefits of paraffin wax is its ability to produce a better scent throw than other waxes. Paraffin wax is commonly used for aromatherapy because it can hold a large amount of fragrance without affecting the burn quality. When comparing the scent throw of a paraffin candle to that of a soy candle, the scent throw is typically stronger in paraffin candles. This is because soy wax is denser than paraffin, requiring more heat to burn, which can take longer to release the fragrance. As the wax melts, the flame's heat vaporizes the liquid wax, diffusing the fragrance oil into the air. Since paraffin burns more easily, it will generally release the fragrance more easily, resulting in a stronger scent throw.
However, it is important to consider the potential health and environmental concerns associated with paraffin wax. Some sources claim that burning paraffin wax releases potentially harmful chemicals, such as volatile organic compounds (VOCs) and phthalates, which can compromise indoor air quality. These chemicals have been linked to adverse health effects, including headaches, shortness of breath, and coughing. On the other hand, other sources argue that the amount of these chemicals released into the air is minimal and that most people are not affected by them.
Additionally, the type of paraffin wax used in candles is crucial. Fully Refined Paraffin undergoes a stringent purification process, resulting in less than 0.5% oil content. This type of paraffin is food-grade and is commonly used in candles, ensuring a high level of purity and safety.
In conclusion, while paraffin candles offer a better scent throw than other waxes, it is essential to consider the potential health and environmental implications associated with paraffin wax. Candle-makers and consumers can make informed decisions by weighing the benefits of a stronger scent throw against any potential risks.

There are debates about the toxicity of paraffin wax, with some claiming it releases harmful chemicals
Paraffin wax is a hotly debated topic in the candle-making world. It is a type of petroleum byproduct, derived from crude oil, coal, or shale oil. Paraffin wax is commonly used to make candles due to its affordability, consistent burn, and ability to hold fragrance and colour. However, there are concerns about its potential toxicity and impact on the environment.
Some sources claim that paraffin wax releases harmful chemicals when burned, including toluene, benzene, and formaldehyde. Toluene is a colorless, water-insoluble liquid that occurs naturally in crude oil and is emitted from gasoline fumes, vehicle exhausts, and cigarette smoke. Benzene is also a colorless liquid derived from natural gas and crude oil. Both toluene and benzene are known carcinogens, and exposure to them has been linked to respiratory issues, headaches, fatigue, and nausea.
However, it is important to note that the levels of these chemicals released by paraffin wax candles are relatively low, and other everyday exposures, such as poor air quality, are more likely to cause significant health issues. Additionally, the type of paraffin used for candles is Fully Refined Paraffin, which has undergone a stringent purification process to remove impurities and reduce the amount of harmful chemicals present. This is in contrast to other types of paraffin waxes like Slack Wax and Scale Wax, which are not used in candle-making and retain higher levels of toxins.
The debate around paraffin wax also includes discussions about its environmental impact. As a byproduct of the non-renewable crude oil industry, the production of paraffin wax contributes to air pollution and environmental degradation. Burning paraffin wax candles releases carbon emissions and particulate matter, further contributing to air pollution. However, it is important to consider that all candles, regardless of their wax base, likely contain some level of toxicity due to the presence of fragrance oils.
While there are valid concerns about the potential health and environmental risks of paraffin wax, it is also widely used and loved for its affordability, accessibility, and ability to hold fragrance. Ultimately, the choice of whether to use paraffin wax or alternative waxes like soy, beeswax, or coconut wax comes down to personal preference and priorities.
