Antimicrobial Agents/Preservatives (Cosmetic Ingredients)

Antimicrobial and preservative agents are incorporated into cosmetic formulations to prevent two types of contamination: primary contamination during manufacturing and secondary contamination after the product is opened and used by consumers.
These ingredients suppress the growth of microorganisms that may enter from external sources and contaminate the product, and over time, they help eliminate microbes to prevent product degradation.
