Candle dyes are usually aniline dyes, which are chemical-based and can be toxic. While some sources claim that dyes are safe when used as intended, with no known health concerns, others suggest that brightly coloured candles may contain toxins. It is important to note that candle waxes are still coloured using toluene derivatives and benzidine-based dyes, which have been linked to cancer. Additionally, synthetic fragrances in candles have been associated with hormone disruption and abnormal cell reproduction, leading to potential tumour growth. As such, it is recommended to opt for candles made from natural materials and scented with essential oils.

Candle dye is usually an organic compound that dissolves in wax
However, it is important to note that the NCA also mentions that candle dyes can be affected by heat, light, fragrance and other agents in a candle. This means that the safety of candle dyes may depend on factors such as the type of wax, wick and fragrance used in formulating the candle.
Some candle manufacturers have expressed concern over the use of chemical dyes and have opted to search for and test candle dyes that are "all-natural". These manufacturers encourage consumers to ask the manufacturer for more information about the origins and contents of the dye.
There are also non-toxic and non-irritating candle dye options available on the market, which are made from food-grade ingredients and do not produce any gas or affect the smell of the candle fragrance when mixed with wax. These dyes are a safer alternative to potentially toxic candle dyes and are suitable for those who wish to avoid exposure to harmful substances.
Overall, while candle dye is usually an organic compound that dissolves in wax, it is important to be aware of the potential risks associated with certain types of candle dyes and to choose candles made with non-toxic and natural ingredients whenever possible.

Some candle dyes are toxic, while others are non-toxic and non-irritating
Candle dyes are usually aniline dyes, which are chemical-based and may be toxic. These dyes have scary MSDS (Manufacturers Safety Data Sheets). As such, some companies choose not to use them, prioritising health over aesthetics. The National Candle Association (NCA) notes that both pigments and dyes are safe when used as intended, and there are no known health concerns with either type of colourant. Reputable candle manufacturers work with colourant companies to develop safe and aesthetically pleasing colour formulations.
However, it is important to note that the NCA also mentions that candle dyes can be affected by heat, light, fragrance, and other agents in a candle. This suggests that the safety of candle dyes may depend on various factors and conditions.
Some candle dyes are advertised as non-toxic and non-irritating. For example, OSBANG offers a range of oil-based candle dyes in 20 colours that are marketed as non-toxic and non-irritating. These dyes are made from food-grade ingredients and are said to be safe for candle-making. They are also claimed not to produce gas or affect the smell of the candles when mixed with wax.
It is worth mentioning that candle dyes and fragrances are considered non-essential ingredients, yet they are often what attract consumers to purchase a candle. This creates a dilemma for manufacturers who want to create pure and healthy products while also appealing to consumers.
To make informed decisions, consumers should carefully review the ingredients and ask manufacturers for more information about the origins and contents of the dyes used in their candles, especially when claims of ""all-natural" or "eco-friendly" are made.

Burning scented candles indoors releases harmful gases and pollutants
Scented candles are a popular product, with the US market for them estimated to be worth around 2 billion USD annually. However, burning scented candles indoors can release harmful gases and pollutants. Studies have shown that indoor candle burning can expose people to dangerous levels of organic pollutants, with higher quantities of pollutants such as formaldehyde, CO2, and volatile organic compounds detected than background levels.
The discharge of combustion gases like carbon monoxide or nitrogen oxide can contaminate the interior environment. A number of polycyclic aromatic hydrocarbons that have been identified as carcinogens, such as naphthalene, anthracene, and pyrene, were also found in candle fumes that are products of wax, aroma substances, or combustion dyes. The most common complaints from those exposed to scented candles include vertigo, headaches, mucosa irritation, respiratory issues, watery eyes, sneezing, a stuffy nose, chest tightness, and a dry or irritated throat.
Candle dyes and fragrances are non-essential ingredients that are added to enhance the aesthetic appeal and scent of the candle. While some candle dyes are non-toxic, others may contain toxins, and it can be difficult to ascertain the exact ingredients used. In general, brightly coloured candles are more likely to contain synthetic dyes, and it is recommended that consumers opt for candles manufactured from natural materials, such as beeswax or soy wax, and scented with essential oils rather than synthetic perfumes, to reduce exposure to pollutants.
It is worth noting that not all candle dyes are harmful, and some manufacturers produce non-toxic and non-irritating candle dyes. These dyes are made from high-quality, food-grade ingredients and do not produce any poisonous or harmful substances when burned. However, it is always a good idea to be cautious and well-informed about the products we use, especially when burned and inhaled.

Synthetic fragrances in candles have been linked to abnormal cell reproduction and tumour growth
Candle dyes and fragrances are non-essential ingredients that are added to candles to make them more attractive to consumers. However, these additives are often synthetic and may contain toxins. For example, candle waxes are still coloured using toluene derivatives and benzidine-based dyes, which have been associated with urothelial cancer development.
Similarly, synthetic fragrances in candles have been linked to abnormal cell reproduction and tumour growth. In 2001, the EPA reported that synthetic fragrances were shown to cause "possible mutagenic and genotoxic effects". These fragrances have also been shown to contain hormone disruptors, which are linked to abnormal cell reproduction and may result in tumour growth.
The use of scented candles has been linked to an increased risk of developing bladder cancer. This is due to the presence of substances such as benzopyrene, which has been associated with chromosome aberrations that are significantly linked to the risk of bladder cancer and colorectal adenoma. Synthetic fragrances used in scented candles also occasionally contain phthalates, a group of hormone-disrupting chemicals that can mimic and block hormones, even at very low levels.
Phthalates can interfere with various bodily functions, including:
- Reproductive processes: Phthalates can modify the release of hypothalamic, pituitary, and peripheral hormones, resulting in abnormal reproductive development and reduced fertility.
- Nuclear receptors: Phthalates can interfere with nuclear receptors, membrane receptors, and intracellular signaling pathways.
- Gene expression: Phthalates can modulate gene expression associated with reproduction.
The fragrance industry is not required to disclose the hidden ingredients in their products, leaving consumers unaware of the potential dangers. It is important to note that natural alternatives, such as essential oils, are often safer and free from harmful chemicals. However, they may be more expensive due to the labour-intensive and costly production process.

Crayons are not recommended for use as candle dye as they will clog the wick
While colouring your candles at home can be a fun activity, it is important to be cautious about the materials used. Candle dyes are usually aniline dyes, which are chemical-based and have concerning safety data sheets. Many people are attracted to candles due to their colour, and manufacturers must balance aesthetics with safety.
Crayons, for example, are not recommended for use as candle dye. The wax used in crayons is different from candle wax and is not meant to be burned. When crayons are used as dye, they will clog the wick as the candle burns, leading to poor burning performance. This is because crayon pigments, like other pigments, do not burn well and will produce soot, smoke, or other byproducts that affect the flame quality, scent diffusion, and overall burning experience. The wick is vital for even burning, and the additional substances from the crayons can clog the wick, impeding proper airflow. This can cause uneven burning, a diminished flame, or even the candle being extinguished prematurely.
If you are looking for natural alternatives to candle dyes, consider using herbs like comfrey, lavender, and rosehip to add interesting colours to your wax. This method works because the colour is dissolved in the wax, similar to a dye. However, do not mix ground herbs or spices directly into the wax, as this will result in a clogged wick.
It is important to prioritise safety when making candles and avoid using any materials that could interfere with the burn quality or cause a hazard.
