Candles are a great way to create a cosy atmosphere, but some candles can release harmful chemicals when burned. These toxins can be released through the wax or fragrance oils, causing sinus mucus and even headaches. To avoid this, opt for candles made from plant-based waxes such as coconut, soy, or beeswax, which burn clean without releasing soot. It is also important to choose candles with natural, non-toxic fragrances and wicks made from cotton, hemp, or wood. Additionally, ensuring that your wicks are adequately trimmed will help to minimise smoke.

What You'll Learn
Clean-burning candles
While there is controversy over the existence of clean-burning candles, certain candles are marketed as nontoxic and clean-burning. These candles are made from plant-based waxes, including coconut, soy, and beeswax, and are claimed to burn without releasing harmful chemicals or soot. However, it is important to note that the fragrance industry is largely unregulated, and terms like "organic soy wax" may be misleading.
When shopping for clean-burning candles, it is recommended to look for candles derived from 100% essential oils and certified nontoxic synthetic ingredients. Transparency in ingredient lists is also key. While paraffin wax has been a subject of concern in the toxic candle debate, there is no conclusive evidence of its health risks. Nonetheless, plant-based waxes offer a natural and sustainable alternative.
To ensure a clean burn, proper candle care is essential. This includes trimming the wicks to the appropriate length and avoiding burning the candle for extended periods. It is recommended to burn candles for a minimum of 1-2 hours and a maximum of 4-5 hours. Rotating multiple candles can be a solution for those who wish to enjoy their scent throughout the day.
Some candle brands that prioritize transparency and nontoxic ingredients include Grow Fragrance, which offers 100% plant-based fragrances, and Fontana Candle Co., which uses beeswax as a key ingredient. When choosing a candle, it is advisable to research the brand and opt for those that use 100% natural wax to avoid inadvertently purchasing a paraffin blend.
While the existence of truly smokeless candles may be debated, following these guidelines can help consumers make more informed choices when seeking nontoxic and clean-burning candle options.

Natural wax candles
Another natural wax option for smokeless candles is beeswax. Beeswax candles are known for their clean burn and lack of synthetic chemicals. Fontana Candle Co., for instance, offers a range of beeswax candles scented with essential oils like cinnamon orange clove, ginger chai, and vanilla. These candles not only provide a natural glow but also fill your space with delightful aromas.
Some natural wax candles combine soy wax with essential oils to create unique and captivating fragrances. The Ilā candle, for instance, features a blend of rose damascena, rose geranium, tuberose, and vetivert essential oils. When burning, it produces a tall, slim flame without any smokiness, filling the room with a sweet and grassy fragrance. Similarly, ESPA's soy wax candle from their positivity range combines jasmine, rose geranium, bergamot, and orange to create a brightening and vibrant aroma.

Paraffin wax candles
To reduce the amount of soot produced, paraffin can be mixed with vegetable oils, such as soy, which burns slower due to its heat-retaining properties. This blend offers a compromise between paraffin's strong scent throw and soy's environmental benefits. However, it is important to note that soy wax is not a pure wax and also impacts the environment due to large-scale cultivation and the process of turning it into wax.
When using paraffin wax candles, it is important to ensure proper ventilation, not only to minimise soot but also to prevent carbon buildup from the burning wick, which is common across all types of candles. While some people associate headaches with candle wax, it is typically the fragrance that causes discomfort rather than the wax itself.
Overall, paraffin wax candles offer a smokeless option with functional and aesthetic benefits, making them a popular choice for creating ambient lighting in homes, events, and even religious ceremonies.

Synthetic fragrances
While essential oils are often used to scent candles, synthetic fragrances are also commonly used to create potent and long-lasting aromas. These synthetic fragrances are developed to perform exceptionally in candle-making, with some being specifically formulated for use with soy wax.
When creating synthetic fragrances, manufacturers may prioritise certain qualities such as strength and longevity. This is achieved through the careful selection and combination of chemical components. However, it is important to note that synthetic fragrances may contain potentially harmful substances. Inhalation of candle smoke could expose you to hundreds of different chemicals, and manufacturers are often not required to disclose all ingredients used. As such, some candle companies opt for natural fragrances, claiming that their products contain zero synthetic chemicals and are directly sourced from nature.
To ensure the safety of their products, some companies formulate their synthetic fragrances without phthalates and adhere to RIFM and IFRA standards for safety and purity. Additionally, some fragrances avoid carcinogens, mutagens, and other toxins, as well as ingredients on the California Prop 65 list. These measures aim to reduce potential health risks associated with synthetic fragrances.

Cotton, hemp, or wood wicks
Cotton wicks are a great option for smokeless candles. When crafted with a cotton core wick, candles tend to burn cleanly and without smoke. These wicks are lead-free and produce a dripless, smokeless flame. The Melt Candle Company, for instance, offers a set of three 3-inch sphere candles with a burn time of 40 hours, crafted with a cotton wick and high-quality wax to prevent dripping and ensure a smokeless burn.
Hemp wicks are not as commonly marketed as a smokeless option as cotton or wood wicks. However, some hemp wicks are designed to be smokeless.
Wood wicks are another popular choice for smokeless candles. Wooden wicks are naturally smokeless and environmentally friendly, as they do not produce smoke or pollute the environment. They are well-suited for aromatherapy candles, as they burn with a slight crackling sound and a pleasant scent. You can find wooden wicks in various sizes and shapes, such as the Visgaler and MadMedic brands, which offer thick wooden wicks that are 5.1 inches long and come with accessories like iron standers, wick stickers, and warning labels for DIY candle-making.
