CMR Substances and Phthalates: What You Need to Know to Protect Your Health

In a world where indoor air quality has become a major concern, it's essential to consider the components of the products we use every day, especially scented candles. CMR substances and phthalates, while widely used in industry, raise many concerns due to their potentially harmful effects on health. In this article, let's discover what they are, their dangers, and how to make informed choices for a healthier home.

What is a CMR Substance?


CMR substances are compounds classified as carcinogenic, mutagenic, or reprotoxic. These three categories define the risks they can pose:

• Carcinogens: Likely to promote the development of cancers.

• Mutagens: Can alter the DNA of cells.

• Reprotoxic: Having harmful effects on fertility or fetal development.


These substances are found in certain chemicals used to scent or stabilize candles. Although regulated in Europe, their presence, even in small quantities, remains a source of concern for many health-conscious consumers.


Did you know? In 2020, a study conducted by ANSES highlighted the presence of CMR substances in many interior products, including candles and room fragrances.

Phthalates: Compounds to Avoid


Phthalates are chemicals used as plasticizers or perfume fixatives. They help prolong the diffusion of fragrances, but they are also criticized for their harmful effects:

• Endocrine disruptors: They can interfere with the hormonal system, causing imbalances.

• Impact on reproduction: Some studies have suggested a link between exposure to phthalates and fertility problems.


Good to know: Many candle manufacturers are now choosing alternatives to phthalates to meet the growing demand for healthier products. Consult the survey conducted by Que Choisir to better understand the risks associated with toxic substances.

Why Are These Substances Problematic in Candles?


When a candle is lit, it releases not only its fragrance, but also the chemical compounds present in its composition. If CMR substances or phthalates are used, they can be released into the air in the form of microparticles, increasing the risk of inhalation.


Case in point: A candle containing phthalates can release harmful fumes, especially in poorly ventilated spaces. This can lead to irritation, headaches, or long-term health impacts.


To avoid these risks, choose non-toxic candles made from natural wax, such as rapeseed wax. Find out more in our article on the benefits of rapeseed wax .


How to Choose Healthy and Natural Candles?


To avoid exposure to these substances, choose candles with more environmentally friendly compositions:

1. Opt for vegetable waxes: Such as rapeseed or soy wax, which are biodegradable and free from controversial substances.

2. Check the fragrances used: Choose scented candles with essential oils or fragrances without phthalates or CMR substances.

3. Focus on transparency: Look for manufacturers who clearly detail the composition of their products.
