Why are we talking about it?

Mineral oils are accused of forming an impermeable film on the surface of the skin. Consumer associations have raised the question of the potential presence of undesirable compounds in mineral oils. The facts: Mineral oils are known in cosmetics as occlusive. This does not mean that they suffocate the skin (which does not breathe), but that the film they form on the skin's surface limits insensible water loss, which puts them in the category of moisturisers. They do not clog pores or cause imperfections. The term mineral oil covers a wide range of ingredients, whose characteristics (structure, viscosity etc.) vary, but which are all composed of hydrocarbons known as “saturated”. Mineral oils used in cosmetics are refined to a high, pharmaceutical grade of purity (1). Mineral oils used in lip products are safe enough to be ingested (2). Mineral oils do not penetrate the skin barrier; they are moreover inert and perfectly tolerated, which makes them a good ally to fragilized skin. Key points to take away: Mineral oils are very well known cosmetic ingredients and are very safe to use (1), both on the skin and on the lips. The purity criteria required in cosmetics limit the presence of undesirable compounds to a minimum, without any health risk (2). The fact that they do not penetrate the skin barrier as well as their occlusive nature are assets in the care of the most fragile skins. They are even used in medical environments in the management of damaged skin (burns, wounds).

Understanding your cosmetics

How are cosmetics kept safe in Europe?

Strict laws make sure that cosmetics and personal care products sold in the European Union are safe for people to use. Companies, national and European regulatory authorities share the responsibility of keeping cosmetic products safe.

What should I know about endocrine disruptors?

Some ingredients used in cosmetic products have been claimed to be ‘endocrine disruptors’ because they have the potential to mimic some of the properties of our hormones. Just because something has the potential to mimic a hormone does not mean it will disrupt our endocrine system. Many substances, including natural ones, mimic hormones but very few, and these are mostly potent medicines, have ever been shown to cause disruption of the endocrine system. The rigorous product safety assessments by qualified, scientific experts that companies are legally obliged to carry out cover all potential risks, including potential endocrine disruption.

Are cosmetics tested on animals? No!

In the European Union, testing cosmetics on animals has been fully banned since 2013. Over the last 30 years, long before a ban was in place, the cosmetics and personal care industry has invested in research and development to pioneer alternatives to animal testing tools to assess the safety of cosmetics ingredients and products.

What about allergens in cosmetics?

Many substances, natural or man-made, have the potential to cause an allergic reaction. An allergic reaction occurs when a person’s immune system reacts to substances that are harmless to most people. A substance that causes an allergic reaction is called an allergen. Cosmetics and personal care products may contain ingredients that can be allergenic for some people. This does not mean that the product is not safe for others to use.
