Is Paraffin Wax Really Harmful? What the Science (and Marketing) Say
Share
At Moon Wick Candle Co., we believe in transparency. While our candles are primarily made of coconut, apricot, and soy, they contain a small amount of paraffin for optimal scent throw and performance. But is paraffin safe to burn, or something to avoid?
Let’s unpack the facts, backed by research, and look at how some of the fear around paraffin may be rooted more in marketing than in science.
🔬 What the Research Says
In 2007, the Bayreuth Institute of Environmental Research conducted one of the most thorough studies on candle wax emissions, analyzing candles made from paraffin, soy, stearin, and beeswax. (Read the summary PDF here)
Key findings:
🔹 All major wax types burned cleanly and safely.
🔹 Emissions across wax types were nearly identical in composition and volume.
🔹 All results showed no toxic chemical levels, well below indoor air quality limits.
👉 Conclusion: When burned properly, paraffin wax is safe and does not release harmful levels of pollutants into the air.
💡 So, Why the Fear Around Paraffin?
Many of the concerns surrounding paraffin wax began in the early 2000s when soy candles started gaining popularity. In order to promote soy as a more “natural” and “safe” alternative, some brands highlighted that paraffin is derived from petroleum, while also citing outdated or poorly designed studies that cast doubt on its safety. This was a strategic marketing move, not necessarily rooted in strong scientific evidence.
🕯️ Why We Use Paraffin in Our Blend
At Moon Wick, we choose to include a small amount of paraffin wax in our candles because it:
✨ Improves scent throw, helping fragrance fill a room more effectively.
✅ Burns cleanly and safely when made with high-quality ingredients and proper wicks.
We test each formula to ensure it meets our standards for performance, aesthetics, and air quality.
✅ Candle Safety Tips
No matter which wax you use, follow these safety practices:
✂️ Trim your wick to ¼ inch before each burn.
⏳ Only burn candles for 3–4 hours at a time.
🌬️ Use in a well-ventilated area, away from fans, curtains, and pets.
🔚 Final Thoughts
It’s easy to get swept up in marketing madness, especially when they claim to protect your health. But when we step back and look at the research, it becomes clear: Paraffin wax is not harmful when used in properly formulated candles.
At Moon Wick, we’re committed to offering beautiful, safe candles with ingredients you can feel good about. Whether you love natural waxes or a high-performance candle, we’re here to blend the best of both worlds.
