ABSTRACT
Cosmetics are daily chemical industrial products that are applied, sprayed or dispersed by other similar methods on body surface for the purpose of cleaning, skin care, beauty and elimination of bad odors. Cosmetics are exposed to a large number of micro-organisms in the process of production, shipment and use. To mitigate the impacts of microbial contamination on the safety of cosmetics, manufacturers need to add preservatives to cosmetics. However, the excessive use of preservatives may cause skin contact allergy. This paper reviews the classification of preservatives in cosmetics and the detection methods of preservatives, compares and summarizes the research progress and advantages and disadvantages of preservative detection techniques.
