Candles are a great way to unwind and relax, but are the ones you're burning safe and healthy? Conventional candles can release harmful chemicals and volatile organic compounds (VOCs) that can affect your health. To avoid potential health risks, opt for candles made from natural, non-toxic ingredients such as soy wax, beeswax, or coconut wax. These natural waxes burn cleaner and produce fewer harmful byproducts. You should also look for candles scented with pure essential oils rather than artificial fragrances, which can contain chemicals with negative health effects. Additionally, choose candles with wicks made from natural materials like cotton, hemp, or wood, instead of metal wicks which can release heavy metals when burned. Prioritize candlemakers that disclose all their ingredients and avoid those that use vague terms like `fragrance' to hide potentially toxic chemicals. By making informed choices, you can enjoy the ambiance of candles while supporting both your health and the planet's well-being.

What You'll Learn
Natural waxes: soy, beeswax, and coconut
Natural waxes such as soy, beeswax, and coconut are often touted as nontoxic alternatives to paraffin candles. Paraffin candles are made from paraffin wax, a by-product of petroleum refining, and are considered highly toxic and environmentally unfriendly. Natural waxes, on the other hand, are marketed as cleaner and healthier options.
Soy wax is a popular choice for those seeking non-toxic candles. However, it is important to note that soy beans are one of the most highly pesticide-controlled crops, and the process of turning soy beans into wax involves chemicals. Additionally, the soy industry is not as sustainable as it claims to be, with soy crops contributing to deforestation and eco-system strain. While soy candles may emit less toxic soot compared to paraffin candles, they still release pollutants into the air when burned.
Beeswax candles have gained popularity for their air-purifying properties. The negative ions released from burning beeswax can neutralise indoor pollutants, providing relief for individuals with asthma, allergies, and hay fever. Beeswax candles are also believed to be suitable for people with chemical and fragrance sensitivities due to their lack of irritating toxins. However, it is important to carefully read labels as some "pure" beeswax candles may contain a significant proportion of toxic paraffin wax.
Coconut wax, derived from hydrogenated coconut oil, is another natural alternative to paraffin. It can be used by itself or blended with other waxes, such as soy. Coconut wax has a lower melting point compared to soy, which can make it less suitable for certain climates and shipping considerations. Additionally, the appearance of pure coconut wax candles may be less smooth than desired, with some users reporting wrinkled or lumpy tops.
While natural waxes like soy, beeswax, and coconut offer advantages over paraffin, it is important to recognise that any burning candle will emit some level of pollution. The key distinction lies in the type and amount of pollutants released, with natural waxes generally considered to be less toxic and, in some cases, capable of improving air quality.

Paraffin wax and its toxic chemicals
Paraffin wax is a by-product of gas and oil refineries, derived from petroleum, coal, or shale oil. It is popular due to its affordability, practicality, ease of use, and cost-effectiveness. However, it has significant drawbacks. Paraffin wax is not biodegradable, is derived from non-renewable resources, and releases toxins during combustion. It has been found to contain known carcinogens (cancer-causing agents) and other toxic chemicals, such as benzene, toluene, formaldehyde, naphthalene, tri-decane, tetra-decane, penta-decane, hexadecane, and volatile organic compounds (VOCs).
The toxins released by paraffin wax can lead to various health issues. Exposure to these toxins can cause sore eyes, headaches, nasal congestion, fatigue, nausea, and allergies. Repeated exposure to toluene can cause respiratory depression, and acute exposure can irritate the mucous membranes of the respiratory tract. Accumulation of fluid in the lungs and respiratory arrest may occur with repeated exposure. Additionally, the toxins in paraffin wax are linked to respiratory irritation and the exacerbation of respiratory conditions, such as asthma.
To avoid the potential health risks associated with paraffin wax, it is recommended to opt for candles made from natural, plant-based waxes such as beeswax, soy wax, or coconut wax. These natural waxes burn cleaner, produce fewer harmful by-products, and are biodegradable and environmentally friendly. They also often use natural fragrances or essential oils, reducing exposure to synthetic chemicals.
It is important to note that while non-toxic candles are a healthier choice, adequate ventilation is still recommended when burning any type of candle to ensure good indoor air quality. Additionally, it is worth considering not just the wax but also the wick material and fragrance source. Pure cotton wicks, for example, are less likely to release toxic chemicals into the air. Transparent ingredient lists and ingredient sources are also important to consider when choosing candles.

Metal wicks and their health concerns
While candles are a great way to relax and unwind, it is important to be aware of the potential health risks associated with burning them. Metal-cored wicks, in particular, have been a cause for concern due to the presence of lead, which can be released into the air during burning. Lead is a toxic substance that can have harmful effects on human health, including headaches, nasal congestion, and allergies.
Lead-cored wicks were commonly used in candle-making to add rigidity to cotton wicks, but their health risks became widely known in the 1970s, leading to a voluntary discontinuation by most manufacturers. However, some candle manufacturers resumed using lead-cored wicks after 1974, and it was not until 2003 that wicks containing lead were officially banned in the USA. Despite the ban, there were still concerns about the potential presence of lead in metal-cored wicks, especially those made of zinc and tin.
Scientific studies on zinc and tin metal-cored wicks have shown that they release a negligible amount of lead, which is considered undetectable. Nonetheless, some candle companies, like Wick & Spice, have completely avoided the use of metal cores in their wicks, opting for pure cotton and paper for stability. This ensures that their customers are not exposed to any potential health risks associated with metal-cored wicks.
To ensure the safest candle-burning experience, it is recommended to opt for candles made with plant-based waxes, fragrances, and wicks. Natural materials like beeswax, soy wax, and coconut wax are considered healthier alternatives to traditional paraffin candles, as they burn cleaner and produce fewer harmful byproducts. Essential oils and botanical ingredients are also preferred over synthetic fragrances to reduce exposure to potentially harmful chemicals.
Additionally, it is important to prioritize transparency and choose candle makers that are willing to disclose their ingredients. Certified organic candles are a good option as they adhere to strict standards, ensuring that no harmful chemicals or synthetic processes are used in their production. By being mindful of these considerations, consumers can create a healthier and more eco-friendly environment in their homes while still enjoying the ambiance and relaxation that candles offer.

Natural fragrances and essential oils
Essential oils for candle-making include citrus, lemon, lavender, ylang-ylang, eucalyptus, and peppermint, among others. Eucalyptus oil is a popular choice for candles burned during the winter or for people with allergies or asthma due to its antiseptic and antibacterial properties. Lemon oil provides a mood boost and improves focus and concentration. Lemongrass oil has a powerful citrus scent and has been used to treat stress, migraines, nausea, and ulcers.
Fragrance oils are also used in candles and are blends of natural and synthetic ingredients. Synthetic aroma compounds are lab-created ingredients that mimic natural fragrances or introduce new, unique scents not found in nature. Solvents and diluents are added to fragrance oils to help maintain their liquid consistency and allow them to mix easily with other products. While essential oils deliver pure, plant-based aromas, fragrance oils are often preferred in candle-making due to their scent stability, longevity, and throw.
To ensure the use of non-toxic fragrance oils, it is important to look for oils that are certified nontoxic and prioritize transparency in listing ingredients.

Eco-friendly packaging and sustainability
Candles are a great way to relax and create a cosy atmosphere, but traditional candles can be harmful to both the environment and human health. Candles made from paraffin wax, for example, have been associated with indoor air pollution and health issues such as headaches and allergies.
However, there are eco-friendly alternatives that are better for the planet and human health. These candles are typically made from natural materials like beeswax, soy wax, or coconut wax, and they burn cleaner, producing fewer harmful byproducts.
The rise of eco-conscious consumers has led to a demand for products that align with environmental values. Candles are no exception, and companies are embracing eco-friendly practices to meet the needs of their customers.
One way to make candles more sustainable is to use plant-based waxes, such as wax blends made from rapeseed and coconut oils. These waxes are sourced from renewable crops and offer excellent performance while being kinder to the planet.
Another important aspect of sustainability is the choice of wick. Biodegradable and clean-burning wicks made from cotton and linen are widely compatible with plant-based waxes and provide a reliable and sustainable option. Wooden wicks, made from sustainably sourced wood, not only enhance the sensory experience with the crackling sound of a wood-burning fire but also align with eco-friendly brand values.
The type of fragrance used in candles can also impact their sustainability. Many traditional fragrance oils contain synthetic chemicals that can be harmful to the environment and human health. Essential oils, on the other hand, offer a completely natural and eco-friendly alternative.
In addition to the choice of materials, companies can adopt eco-friendly practices to reduce their environmental impact. This includes repurposing leftover wax, offering refillable candles, and using energy-efficient production processes.
Sustainable packaging is another way for candle companies to demonstrate their commitment to the environment. Kraft paper and cardboard are commonly used for candle boxes as they are sturdy, flexible, and can be moulded into various shapes and sizes. Plastic-free, zero-waste, recyclable, and compostable materials are also increasingly being used to package candles, reducing waste and adding brand value.
Overall, the rise of eco-conscious consumers has driven the development of eco-friendly and sustainable practices in the candle industry. From plant-based waxes and natural fragrances to reusable packaging and energy efficiency, candle companies are finding innovative ways to reduce their environmental impact and meet the needs of their environmentally conscious customers.
