Quaternium-79 hydrolyzed keratin (inci)

Quaternium (see also Polyquaternium) refers to complex quaternary ammonium compounds. Quaternary ammonium compounds, also called quats, have quaternary nitrogen atoms, i.e. all four hydrogen atoms of the ammonium ion (nitrogen atom) are replaced by organic residues. The compounds are therefore cationic, i.e. they have a positive charge. " hydrolyzed keratin refers to keratin peptides (these are often obtained from spring proteins by the action of keratinases of Bacillus subtilis AMR (Villa AL et al. 2013). The aim is to obtain a high degree of hydrolysis and a final product containing a large variety of free amino acids).

Quaternium-70 hydrolyzed keratin is used in cosmetic formulations. The substance acts as an antistatic agent (reduces static charges by neutralizing the electrical charge on the surface, for example of hair), as a hair conditioning agent (makes hair easy to comb, smooth, soft and shiny and gives it volume) and as a skin care product.
