PHENOXYISOPROPANOL.

Valuable CAS 770-35-4 / PRESERVATIVE, SOLVENT

Phenoxyisopropanol functions primarily as a mild cosmetic preservative, crucial for inhibiting microbial proliferation and extending product shelf life. It additionally serves as an effective solvent, enhancing formulation stability and optimizing the dermal absorption of other active ingredients.

Antimicrobial Preservative Preservative Boosting Masking Solvent Stabilizer Penetration Enhancer

Science

Mechanism of Action

This compound exerts its preservative action by disrupting the cellular processes of bacteria, fungi, and other microorganisms, thereby preventing their growth and subsequent product degradation. As a solvent, it facilitates the uniform dispersion and stabilization of diverse components within a formulation. Furthermore, its ability to enhance the permeability of the skin barrier can augment the delivery and efficacy of co-formulated active substances. It also contributes to surface protection against harmful bacteria on the skin.

Considered generally safe for cosmetic use at concentrations up to 1.0%, as evidenced by its approval under Annex V of the EC Cosmetics Regulation following SCCS assessment. Higher concentrations, however, may induce skin irritation, characterized by redness, itching, discomfort, prolonged dryness, or mild dermatitis. It is considered a safer alternative to some other preservatives due to its lower irritation potential. Regulatory bodies, including the FDA and the European Medicines Agency, provide guidelines for its safe application.
