Protheragen-ING offers a wide range of tests to evaluate the efficacy and stability of preservatives in cosmetics.
Protheragen-ING can perform quantitative detection of commonly used preservatives in cosmetics, such as: benzoic acid, methylisothiazolinone, methylchloroisothiazolinone, benzyl alcohol, phenoxyethanol; 4-hydroxybenzoic acid methyl ester, etc.
