Hair dyes (oxidative)

Description

Oxidation hair dyes form permanent colours from uncoloured precursors on and in the hair, which are permanently adhering and cannot be washed out. An alkalising agent (eg gel or cream with ammonia) lets the hair swell so that the colour precursors and oxidants (eg lotion or solution with hydrogen peroxide) penetrate more easily into the interior of the hair. Based on the colourless colourant precursors (referred to as developer and coupler), dyes are formed by means of an oxidant which are permanently anchored in the hair. The final colour result is attributable to different couplers and developers (substituted diaminobenzenes, aminophenols or dihydroxybenzenes). Depending on the colouring capacity it is distinguished between intensive colouring, oxidative tinting, hair colours or colorations. Usual application forms are caring cream, gel or shampoo formulations. The basis of the cream colours is made up of ethoxylated or sulphated fatty alcohols, fatty amides or ethoxylated vegetable oils. These products are often complemented by caring components such as cationic polymers and lanolin derivatives. Hair dyeing gels are oily liquids which form a gel when mixed with hydrogen peroxide. They are formulated on the basis of soaps (AMMONIUM OLEATE), ethoxylated non-ionic, surface-active substances or anion / cation complexes or mixtures of these substances. Colouring shampoos have a similar composition to gels but contain in addition foaming raw materials. Furthermore, oxidative hair colorants also contain antioxidants (eg sodium sulfite or ascorbic acid), thickeners and perfume oils.

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.
