Abstract
Preservatives have been used and known to mankind since a very long time. These are used in cosmetics to increase the shelf life of product so that aroma, taste and the cosmetics itself can be stored for a longer period of time. Also cosmetics degradation is prevented by them. Preservatives, whether natural or artificial, work as in three different ways: Antimicrobial, Antioxidants and Act on enzymes. In antimicrobial, the growth of microbes like bacteria and fungi is inhibited. In antioxidants the process of oxidation is either delayed or stopped. And the one that acts on enzymes stops the ripening or aging of cosmetics product. Preservation is important part in many industries, such as the cosmetic and pharmaceutical industries, as the shelf life of many cosmetic and pharmaceutical products is important. The present review is an extensive compilation of various preservatives obtained from plant, synthetic and microbial source.The safety of preservatives is always coming into question. Since these are all biologically active products, they all have potential for being toxic, or irritating, or sensitizing.
