PEG-200 HYDROGENATED CASTOR OIL/IPDI COPOLYMER.

Insufficient Data CAS 207620-98-2 / SKIN CONDITIONING

PEG-200 Hydrogenated Castor Oil/IPDI Copolymer is a castor oil-derived polymer designed to enhance cosmetic formulations by thickening oil phases and forming clear gels. It also effectively suspends particulates for uniform product texture and acts as a skin conditioning agent.

Summary

skin conditioning emulsifying surfactant thickens oils forms clear oily gels suspends particles

Science

Mechanism of Action

This copolymer functions primarily as a versatile skin conditioning agent. As a polyethylene glycol derivative, it exhibits surfactant and emulsifying properties, facilitating the stable blending of oil and water components within a formula. It further contributes to formulation aesthetics by increasing viscosity in oil-based systems, creating clear, gel-like textures, and maintaining even suspension of dispersed particles like pigments or mineral filters.

Stability

Polyethylene glycols and their derivatives, including this copolymer, generally exhibit good stability and are not highly susceptible to microbial degradation, often mitigating the need for additional preservatives. Related PEG-60 Hydrogenated Castor Oil is noted to maintain stability at a neutral pH.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

While related PEG Castor Oils (up to 50%) and PEG Hydrogenated Castor Oils (up to 100%) have been deemed safe by the CIR Expert Panel when formulated to be non-irritating, PEG-200 Hydrogenated Castor Oil/IPDI Copolymer was specifically noted for exclusion from these broader safety conclusions, meaning it has not been directly evaluated for safety by the CIR. A general concern for PEG ingredients is the potential presence of 1,4-dioxane, a manufacturing byproduct, which requires rigorous purification to mitigate. EWG classifies PEG-200 Hydrogenated Castor Oil as 'Restricted' for its VERIFIED products due to potential toxic impurities if safety guidelines are not met, particularly in inhalable forms.

Our Assessment

Verdict

Insufficient Data

This ingredient offers valuable multifunctional properties for formulation, including thickening, emulsifying, and skin conditioning, with a low reported irritancy and comedogenicity; however, direct safety assessments for this specific copolymer by regulatory bodies are currently lacking, warranting careful consideration and rigorous quality control for 1,4-dioxane purity.
