GLYCERYL HYDROGENATED ROSINATE.

Valuable CAS 65997-13-9 / FILM FORMING

Glyceryl Hydrogenated Rosinate is a precision film-forming emollient that creates a protective, water-insoluble barrier on the skin. This durable film effectively minimizes moisture loss, enhances hydration, and improves product adherence, while imparting a desirable smooth feel to formulations.

Summary

Emollient Film forming Adhesive Moisture barrier enhancement Hydrating

Science

Mechanism of Action

This ingredient functions by forming a robust, water-insoluble film across the skin's surface. This barrier is instrumental in preventing transepidermal water loss, thereby maintaining optimal skin hydration. Concurrently, it acts as an adhesive, improving the longevity and adherence of cosmetic products and contributing to a soft, smooth tactile finish.

Safety

Safety Profile

CIR Status
Safe as used
Max tested
76.8%
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that glyceryl monoesters, including Glyceryl Hydrogenated Rosinate, are safe for use in cosmetics under current practices and concentrations. However, due to the potential presence of residual rosin, a known allergen, there is a moderate risk of allergic reactions. While generally well-tolerated at appropriate concentrations, patch tests are recommended for individuals with sensitive skin, and it should not be utilized in excessive quantities. The maximum reported concentration for leave-on products is 10%, while rinse-off products like depilatories may contain up to 76.8%.
