POLY(METHYL STYRENE ISOPROPANOL KETONE).

Valuable CAS 163702-01-0 / LIGHT STABILIZER

This high molecular weight polymer primarily functions to safeguard cosmetic formulations. It acts as a light stabilizer, effectively preventing product degradation caused by UV exposure, thus maintaining the integrity and efficacy of skincare compositions over time.

Summary

Stabilizing agent Light stabilizer

Science

Mechanism of Action

POLY(METHYL STYRENE ISOPROPANOL KETONE) works within the cosmetic product matrix as a photostabilizer. It absorbs or reflects harmful UV radiation, thereby preventing the chemical breakdown of other light-sensitive ingredients and preserving the overall stability and performance of the formulation.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

While POLY(METHYL STYRENE ISOPROPANOL KETONE) has not been individually reviewed by the CIR Expert Panel, the broader category of 'Styrene and Vinyl-type Styrene Copolymers' is considered safe for cosmetic use, with percutaneous absorption deemed unlikely due to large molecular size. Related polymers like Poly(α-methylstyrene) have shown no adverse health effects or skin irritation. It is important to distinguish the polymer from its monomer, alpha-methylstyrene, which is classified as an irritant. INCI Beauty reports 'No penalty' across all safety categories for this ingredient, and The Good Scents Company lists no GHS classifications or specific toxicity concerns.
