Candles are a great way to set the mood and awaken the senses through scent and sight, but are they harmful to our health? Many conventional candles contain toxins such as lead, formaldehyde, and other chemicals that can be dangerous, especially for those with respiratory conditions. These toxins can be released into the air we breathe, causing potential health issues. However, there is a growing trend of non-toxic candles made from natural ingredients like beeswax, coconut wax, and essential oils. These candles provide an eco-friendly and healthier alternative to traditional candles, without compromising on scent and style. With consumers becoming increasingly conscious of the products they use, it's important to explore whether popular candle brands, such as Yummi Candles, are taking steps towards creating non-toxic and environmentally sustainable products.

Yummi Candles' ingredients and wicks
Candles are primarily made of wax and a wick. Yummi Candles offers a hands-on experience in Toronto's Distillery District, where customers can create their own scented candles. They guide customers through the process of choosing fragrances from their catalogue and blending them with their proprietary plant-based waxes and premium wicks.
While the specific ingredients of Yummi Candles' wicks are not publicly disclosed, the company emphasizes safety and is a proud member of the National Candle Association (NCA). The NCA has voluntarily banned lead wicks and supports the removal of candles with lead wicks from store shelves. They also provide safety guidelines for burning candles, such as keeping wicks trimmed and ensuring proper ventilation to prevent incomplete combustion and sooting.
Most wicks manufactured in the United States today are made of 100% cotton, with no metal core. Cotton wicks are considered safe for candle-making, along with those made from paper, zinc, or other non-metallic materials. Yummi Candles' emphasis on safety and their alignment with NCA guidelines suggest that their wicks are likely made from these standard, non-toxic materials.
To ensure the safety of their customers, it is important for candle companies to be transparent about their ingredients. While the specific ingredients used by Yummi Candles may not be publicly available, their commitment to safety and the hands-on nature of their workshops suggest that they prioritize the well-being of their customers and the quality of their products.
Overall, the ingredients and wicks used by Yummi Candles are likely to be safe and non-toxic, given their alignment with industry standards and their focus on providing a positive candle-making experience for their customers.

Health and safety concerns
Candles are a popular way to enhance the ambiance and scent of a room, but it's important to be aware of potential health and safety concerns. While candles can be enjoyable, some may contain toxic ingredients that can negatively affect your health and the environment.
Firstly, let's talk about wicks. Candle wicks have historically been made from metal fibers, such as lead, which can release toxic substances into the air when burned. Lead has been linked to various health issues, and its presence in candles is a significant concern. To identify if a candle has a lead-core wick, you can perform a simple test: rub a piece of paper on the tip of an unused metal wick. If it leaves a gray pencil-like mark, it likely contains lead. It is recommended to choose candles with wicks made from safer materials such as cotton, paper, zinc, or non-metallic fibers.
Now, let's discuss the wax. Many conventional candles are made with paraffin wax, which is derived from petroleum. Burning paraffin wax releases chemicals like benzene and toluene, which are known carcinogens. These chemicals can cause serious health issues, including headaches, nausea, respiratory problems, central nervous system dysfunction, and even birth defects. Therefore, opting for candles made from natural wax alternatives, such as beeswax, coconut wax, or soy wax, is a healthier choice. These natural waxes are non-toxic and provide a cleaner burn.
Additionally, fragrance is an important consideration. Candles with artificial fragrances or those labelled as “fragrance" or "parfum" can be problematic. The term "fragrance" often serves as a catch-all term for various chemicals, including phthalates, which are known endocrine disruptors. These chemicals can have detrimental effects on your health. Instead, opt for candles that use 100% naturally derived essential oils or provide transparency about their fragrance sources.
Lastly, proper candle care is essential for safety. Always burn candles in proper candle holders or bases, ensuring they are well-ventilated and away from drafts to prevent incomplete combustion and sooting. Keep wicks trimmed, and extinguish candles when they get within 2 inches of their holders or decorations.
In conclusion, while candles can enhance your environment, it's crucial to prioritize your health and safety. By choosing candles with non-toxic wicks, natural waxes, and transparent ingredient lists, you can minimize potential risks. Additionally, following proper candle care practices will ensure a safer burning experience.

Eco-friendly alternatives
While candles can create a warm and soothing environment, especially during the chilly fall and winter seasons, they might be harming your health and the environment. Many conventional candles are made with paraffin wax, also known as petroleum wax, which is not healthy or sustainable. Some candles also contain lead in the wicks, which can release toxins when burned.
- Organic beeswax candles: These candles are naturally non-dripping, do not smoke, and release negative ions into the air, which has a purifying effect by attracting allergens.
- Soy wax candles: Soy wax is a natural, renewable resource that can be sustainably sourced. It is often used as an alternative to paraffin wax, which is derived from petroleum.
- Coconut wax: Coconut wax is another natural, renewable, and sustainable alternative to paraffin wax.
- Electric wax warmers: Wax melts slowly melt and release their scent into your home without polluting the air with a lit wick.
- Room spray fresheners: You can make essential oil room sprays with all kinds of ingredients, such as vodka or witch hazel, to create a lasting scent in your home.
- Stovetop potpourri: Create a potpourri mix and add it to a pot of boiling water on your stove. As it simmers, it will fill your home with a wonderful scent. You can use dried or fresh fruit, such as cranberries, oranges, apples, and lemons.
- Incense: Incense creates smoke, which may not be preferred by some people, but it does not release the same kind of pollution as candles. Make sure to buy high-quality incense made with natural ingredients.
- Decorative fragrant natural elements: Decorate your home with fragrant dried spices like nutmeg, cloves, and cinnamon, or dried fruits like lime, orange, and lemon. You could also bring in pine branches or flowers to create a light and fresh scent.
When choosing candles, opt for those that come in reusable jars, especially hand-blown glass jars. Also, ensure the wicks are made from natural materials like cotton, wood, or paper, and avoid lead wicks. You can test for a lead wick by rubbing a piece of paper on the tip of an unused wick; a lead-core wick will leave a grey pencil-like mark, while zinc or tin will not.
Some recommended brands for non-toxic candles include Lite + Cycle, Ellis Brooklyn, Slow North, and P.F. Candle Co. These brands use natural ingredients, such as essential oils, soy wax, and wooden or cotton wicks, and adopt sustainable practices.

Candle care and maintenance
Candle Care Tips:
- Trim the wicks: Keeping candle wicks trimmed to around 6mm is crucial for a controlled flame and less smoke. Trimming also prevents black residue from forming around the candle jar and ensures the candle smells fresh every time.
- Maintain the wax pool: Keep the wax pool clear of wick trimmings, debris, and burnt matches.
- Avoid drafts: Air drafts can cause uneven burning and soot formation.
- Ventilate the room: Proper ventilation is necessary to prevent incomplete combustion and soot issues.
- Stable surface: Always place candles on a stable, heat-resistant surface or in a candle holder to avoid damaging furniture.
- Burn in a holder: Candles should be burned in proper candle holders or bases, kept 2.5 inches apart when burning outside a holder.
- Extinguish safely: To prevent hot wax from splattering, hold your finger in front of the flame and blow at it. Extinguish candles when they get within 2 inches of their holders or decorations.
- Avoid unattended burning: Never leave a burning candle unattended, and keep it out of the reach of children and pets.
- Storage: Store candles in a cool, dark place like a cupboard or basement to maintain their quality.
Candle Maintenance Tips:
- First burn: During the first burn, allow the candle surface to melt completely to prevent a rim of hard wax from forming.
- Do not burn completely: Stop using the candle when around 0.5 inches of wax remains to protect the container and prevent overheating.
- Clean the holder: After removing the spent candle, use a spoon to scrape the melted wax from the holder, then clean and dry it.
- Recycle: Reuse the glass container as desired. Clean any remaining wax with hot water, and repurpose the container as a pot for pens or a tealight holder.
By following these candle care and maintenance tips, you can enhance your candle-burning experience and prolong the life of your candles.
