Lighting a scented candle is much more than simply illuminating or perfuming a room: it's about creating an atmosphere, awakening the senses, and enriching the inner experience. But not all candles are created equal. Most, made from paraffin wax , can alter air quality and negatively impact your olfactory comfort.
In this article, we will tell you more about this wax, also called "mineral wax":
What is paraffin and why should it be avoided?
Paraffin wax is a petroleum derivative, widely used for its stability and low cost . It is derived from the processing of crude oil . In hard or liquid form, it is used as a raw material in the manufacture of candles and scented candles . It makes up the majority of industrial candles, but its combustion can release:
-
Volatile organic compounds (VOCs) such as benzene or toluene,
-
Soot and fine particles , which pollute indoor air,
-
Risks of respiratory irritation , asthma and allergies.
Even when a paraffin candle is not burning, some substances can be released into the air. Its widespread use also has a significant environmental impact : petroleum is not renewable, and recycling wax residue is complex.

Why is paraffin used?
- Low cost compared to alternatives like soy wax or beeswax .
- Stable fuel at room temperature, with a suitable melting point .
- Easy to mold, color and combine with synthetic fragrances .
But this massive use has a hidden cost: the combustion of paraffin releases toxic substances and degrades indoor air quality .
The potential dangers of paraffin candles
Emissions and air quality
When a paraffin candle is lit , it releases high amounts of volatile organic compounds (VOCs) such as benzene or toluene , up to 11 micrograms of benzene per hour .
These fine particles can cause respiratory irritation, coughing or worsening of asthma , especially in a poorly ventilated space.
Environmental impact
Paraffin production relies on a non-renewable resource: oil . Its extraction and processing emit elemental carbon , contributing to greenhouse gases and global warming .
In addition, candle wax residue mixed with chemical dyes complicates the recycling of containers (metal, glass or ceramic jars).
Alternatives to paraffin candles
Plant-based waxes: a healthier solution
Candles made from soy wax , rapeseed wax or coconut wax offer a cleaner burn , with fewer fine particles and no heavy metal emissions.

Beeswax: tradition and nobility
Used for centuries, beeswax is a natural ingredient that releases a sweet honey scent. While its price remains high, its durability makes it an attractive alternative for those seeking a quality handcrafted candle .
Refillable and reusable candles
Another alternative is to opt for refillable natural candles . They reduce waste and extend the life of the containers. For example, you can use acandle wax refill to refill your favorite jar, rather than buying a new candle each time.
Beware of so-called “natural” candles
Not all candles sold as natural actually are. Some manufacturers mix vegetable wax and paraffin to reduce costs, or use fragrances containing phthalates and CMR substances (carcinogenic, mutagenic or toxic to reproduction).
Wax alone is not enough to guarantee a healthy candle: you also need to check
-
The composition of the perfumes (without phthalates or CMR substances)
-
The type of wick (preferably 100% cotton or wood)
-
Manufacturing (local, artisanal, responsible)

Practical tips to limit the risks
Using a candle safely
Regardless of the type of wax used , certain simple precautions can reduce health risks :
- Trim the wick to 5 mm before each use.
- Do not let the candle burn for more than 3 hours at a time .
- Ventilate the room after combustion.
- Never leave a burning candle unattended .
Recognizing a healthier candle
Before buying, take the time to check the label . A quality natural candle should clearly state:
- “paraffin-free” or “100% vegetable wax” ,
- “without CMR” (Carcinogenic, Mutagenic, Reprotoxic),
- “Phthalate-free” ,
- of French origin .
