Paraffin Candles: Facts vs. Myths — Are They Really Harmful?

In the world of home ambiance and self-care, few items are as beloved as a beautifully scented candle. But as awareness grows around health and sustainability, so do questions. One of the most common: Are paraffin candles harmful to your health?In this article, we explore the scientific background, clear up misconceptions, and provide some insight into the choices behind natural candle-making.

What Is Paraffin Wax?

Paraffin wax is a petroleum by-product derived from the oil refining process. It has long been used in candle production due to its low cost and its efficiency in dispersing scent. One lesser-known fact is that paraffin burns at a higher temperature, which means it requires less fragrance to produce a noticeable scent throw.However, the downside of this higher burn temperature is that it can release trace chemicals into the air, especially when candles are burned for prolonged periods or in poorly ventilated spaces.

What Does the Research Say?

Some studies, such as one conducted in 2009 by South Carolina State University, found that paraffin candles may release small amounts of substances like toluene and benzene—compounds that can be harmful in high concentrations. While these emissions were minimal and within safety limits during average use, they have sparked concern among consumers looking to reduce chemical exposure at home.Organizations such as the European Candle Association maintain that paraffin candles are safe when used properly, but it's clear that a growing number of people prefer alternatives that align better with personal health and sustainability values.

Our Approach to Natural Candle Making

At The Candle Salon Group, we exclusively use plant-based wax — specifically, rapeseed wax.(Brassica Napus) This local and renewable wax burns cleanly and evenly, produces little to no soot, and is biodegradable.Unlike paraffin, Brassica napus wax burns at a lower temperature, which allows for a slower, longer-lasting fragrance release. We also choose not to use soy wax or beeswax — the reasons behind that choice will be the topic of a future post.Importantly, all our candles are free from phthalates and parabens — two synthetic additives that have been linked to hormone disruption and skin sensitivities in various studies. Transparency in ingredients is a value we hold dearly.

Summary

While paraffin candles are generally considered safe under typical conditions, many individuals are turning to natural wax alternatives for peace of mind, environmental reasons, or health considerations. Plant-based waxes such as Brassica napus offer a clean-burning, sustainable option without compromising on fragrance or ambiance.Understanding what goes into your candles helps you make informed choices about the products you bring into your home — and that’s always a good thing.
