POLYVINYL ISOBUTYL ETHER.

Insufficient Data CAS 9003-44-5 / FILM FORMING

Polyvinyl Isobutyl Ether is a synthetic polymer employed in cosmetic formulations primarily for its film-forming and binding capabilities. It contributes to enhanced product texture and durability by creating a stable, cohesive film on the skin's surface.

Summary

Film-forming agent Binder

Science

Mechanism of Action

Upon application, Polyvinyl Isobutyl Ether forms a continuous and stable polymeric film on the stratum corneum. This film acts as a physical matrix, which not only improves the longevity and texture of the cosmetic product but also aids in binding other ingredients together.

Stability

This polymer exhibits stability towards both dilute and concentrated alkaline solutions, as well as dilute acids. Optimal storage conditions require a cool, dry environment (10-30℃), shielded from light and heat, to maintain its integrity.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Polyvinyl Isobutyl Ether has not been subject to specific safety review by the Cosmetic Ingredient Review (CIR) or the Scientific Committee on Consumer Safety (SCCS) for cosmetic applications. While the polymer itself (CAS 9003-44-5) is not classified with GHS hazards, its monomer, Vinyl Isobutyl Ether (CAS 109-53-5), is recognized as causing skin irritation (H315) and serious eye irritation (H319). The FDA lists the polymer as an indirect additive in food contact substances, which is not directly applicable to its safety in topical cosmetic use.

Verdict

Insufficient Data

While Polyvinyl Isobutyl Ether demonstrates functional properties as a film-former and binder, the absence of specific cosmetic safety assessments and clinical efficacy data for skin benefits warrants a cautious approach to its inclusion in precision skincare formulations.
