Background information on use in cosmetics

Butylene Glycol is a divalent alcohol in chemical terms. Alcohols such as butylene glycol are, together with water, the most important solvents for cosmetic preparations. Butylene glycol is primarily used as humectant for O/W emulsions. Alcohols are generally hydroxy derivatives of aliphatic and alicyclic saturated and unsaturated hydrocarbons. The systematic names are derived from those of the parent hydrocarbons by adding the ending -ol. Depending on the number of OH groups included in the molecule, reference is made to monohydric, bivalent (diols) or trivalent alcohols (triols). Depending on the position of the OH group(s) in the molecule it is distinguished between primary, secondary and tertiary alcohols. Especially the following alcohols are used as ingredients in cosmetic products: Ethyl alcohol (ethanol) and isopropyl alcohol (isopropanol) as well as the polyvalent alcohols glycerine (glycerol), propylene glycol, butylene glycol, pentylene glycol and hexylene glycol.

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.
