HDI/PPG/POLYCAPROLACTONE CROSSPOLYMER.

Valuable CAS 302791-95-3 / ANTICAKING

A synthetic polymer utilized in precision skincare for its multi-functional properties. It primarily acts as an anticaking agent and texture enhancer, while also delivering a subtle soft-focus and wrinkle-concealing effect on the skin. This ingredient contributes to a refined, creamy feel in formulations.

Summary

anticaking soft-focus wrinkle-concealing texture enhancer solubilizer solvent

Science

Mechanism of Action

This synthetic crosspolymer functions by forming a fine, film-like network on the skin's surface, creating a soft-focus effect that optically blurs the appearance of fine lines and wrinkles. Its polymeric structure also modifies the tactile properties of formulations, imparting a creamy, elegant texture. As an anticaking agent, it prevents agglomeration in powdered products, ensuring smooth application. Its polypropylene glycol (PPG) component further contributes to formulation stability and can serve as a solubilizer or solvent.

Dusting Analysis

Commonly dusted

As a powder-form ingredient, HDI/PPG/Polycaprolactone Crosspolymer was initially noted for 'insufficient data for chronic respiratory' concerns by the CIR Expert Panel. However, subsequent review determined its large molecular weight (>10,000 Da) limits skin penetration, and residual HDI monomer levels in topical formulations up to 2.4% were below detection limits (0.4 ppm). While topical application is considered safe, careful handling during manufacturing to minimize airborne exposure is a general best practice for powdered ingredients.

The CIR Expert Panel initially deemed data 'insufficient' for chronic respiratory concerns regarding HDI polymers, including this crosspolymer. However, for topical applications, its molecular weight exceeding 10,000 Da suggests negligible skin penetration. Furthermore, formulations containing up to 2.4% of this ingredient exhibited residual HDI monomer levels below detection (0.4 ppm). Consequently, the CIR Science and Support Committee extended a 'safe as used' conclusion for topical applications based on these mitigating factors.
