Preservatives for Cosmetics
Several products in the market contain ingredients which make cosmetic systems very difficult to preserve. For example, personal care products contain significant amounts of water and other ingredients that may be susceptible to contamination by microorganisms like bacteria, fungi and molds.
In order to prevent such happenings, formulators include preservatives
in their formulations. Depending on the type of preservative selected, they can kill or inhibit the growth of micro-organisms, and protect a formula from microbial contamination.
While applying a cosmetic for personal care use it should be assured that its free from any contamination. Product must be preserved adequately to kill the microorganisms that are introduced by the consumers themselves. However, one also must be careful with over-preserving a product as too much preservative in a product is not good either.
