Candles: Is paraffin more dangerous than vegetable waxes?

When you light a candle at home, you probably don't immediately think about what's in it. However, there are several types of wax used to make candles, and they don't all have the same impact on your health. The question many people ask is: " Is paraffin really worse than vegetable waxes, like soy or rapeseed? " Let's take a closer look, in a simple way.

To begin with, what is paraffin?

Paraffin is a wax derived from petroleum. It is often used in industrial candles because it is easy and inexpensive to produce. However, when it burns, it can release substances that are potentially harmful to health, including certain hydrocarbons, which are irritating or toxic chemical compounds.

Important : If you choose a paraffin candle, always check the country of manufacture or origin. Paraffin produced within the European Union meets strict standards, thus limiting potential health risks.

And what exactly are vegetable waxes?

Vegetable waxes, such as soy or rapeseed wax, are made from plants. They are often perceived as a healthier alternative because they come from renewable sources (plants) and because they appear to produce less smoke and fewer toxic substances when burned.

But what do scientific studies say? Is it really better to choose these vegetable waxes?

What do scientific studies say?

Scientific studies are rather reassuring: they indicate that under normal conditions of use (good quality candles, properly ventilated room), the health impact of candles, whether made of paraffin or vegetable wax, generally remains low.

However, there are some interesting differences to note:

1. Released chemical substances (VOCs)

When they burn, all candles release volatile compounds (called VOCs), but paraffin can produce slightly more problematic substances, such as certain toxic hydrocarbons (e.g., toluene) or formaldehyde, although the amounts remain small.

Vegetable candles, such as those made from soy or rapeseed oil, generally release fewer of these irritating compounds. This is particularly important for people with sensitivities or respiratory problems.

2. Fine particles and soot

Whether the wax is vegetable-based or not, all candles produce fine particles when they burn. These particles are very small, almost invisible, but can irritate the respiratory tract in large quantities. The good news? If you use quality candles with a well-suited wick and avoid drafts, both paraffin and vegetable wax candles produce very little visible soot and few harmful particles.

3. The risks of allergies and respiratory irritation

Here again, vegetable waxes have the advantage: they are generally better tolerated. Candles made from vegetable wax (soy or rapeseed) less often cause minor irritation of the eyes, nose, or throat than paraffin candles. This is a significant benefit for people with asthma or allergies.

However, be aware that the main allergy risk often comes from the fragrances added to candles, and not really from the wax itself. So, whatever your choice, always check the ingredients, especially the fragrances.

Conclusion: What to choose?

To put it simply:

• Vegetable wax candles (soy, rapeseed, etc.) are generally a little better tolerated and slightly healthier than paraffin candles.
• Paraffin used properly (correct quality, good ventilation, EU origin) does not constitute a real danger to health either, but it can produce more irritating compounds.

For regular use, or if you have sensitivities or asthma, vegetable wax candles are a better option. But in any case, always choose a good quality candle, ventilate your home well when lighting them, and peacefully enjoy the warm atmosphere they create!

At Ely's Candle , we have chosen to use exclusively vegetable wax (soy or rapeseed) from French suppliers.
