Antimicrobial activity of Butyl acetate, Ethyl acetate and Isopropyl alcohol on undesirable microorganisms in cosmetic products
The microbiological contamination risk of a cosmetic product has to be assessed by the manufacturer, according to the composition, to determine whether microbiological testing is required. Certain ingredients in cosmetic formulations help to create an environment hostile towards microbial growth. In this study, the influence on microbial survival of some solvents used in nail varnishes was evaluated. The purpose of this study was two‐fold. The first was to define the thresholds to be considered for the exemption of products from microbiological testing. The second was to assess the cross‐contamination risk linked to the use on successive consumers of solvent‐based products in beauty salons.
