Detection and Quantification of Preservatives in Green Cosmetics

Abstract Preservatives are used in cosmetic formulations to provide protection against microbial growth to ensure the safety and the quality during their shelf life. Benzyl alcohol, sodium benzoate and sorbic acid are the preservatives that can be used in green cosmetic formulations. According to the cosmetic legislation usage of above indicated preservatives are restricted and thus determination and quantification of them from the cosmetic products have become important. In this study analytical methods are given to enable the determination of benzyl alcohol, sodium benzoate and sorbic acid. The methods are based on extracting the preservative agents from four different pharmaceutical form (solution, emulsion, gel and cream) of the various cosmetic matrices and later on detection in the scope of the basic chromatographic data and test parameters by High Performance Liquid Chromatography (HPLC) system with UV Detector.
