ISOPROPYL SORBATE.

Insufficient Data CAS 44987-75-9 / ANTIMICROBIAL

Isopropyl Sorbate functions as an ester-based antimicrobial preservative, crucial for maintaining the microbial integrity and extending the shelf life of cosmetic formulations by inhibiting the growth of bacteria and fungi.

antimicrobial preservative

Science

This ingredient operates by establishing an environment within formulations that actively inhibits the proliferation of microorganisms, including bacteria and fungi. As an ester of sorbic acid, its mechanism of action is consistent with its parent compound, disrupting vital microbial processes to prevent spoilage.
