Glycine Soja (Soybean) Sterols

GLY

8/10

Concern level

High concern

A soybean-derived phytosterol mixture used in cosmetics as a skin-conditioning and barrier-supporting emollient. It helps improve product feel, supports the skin lipid barrier, and can reduce dryness by contributing to a more supple, moisturized skin surface. Because it is a mixture of plant sterols rather than a single defined molecule, several physicochemical values are not fixed.

Risks & Warnings

Generally low risk in cosmetic use. Main concern is rare sensitivity in individuals allergic to soy-derived materials. As a lipidic ingredient, it may feel rich in very oily or congestion-prone products, though it is not considered a high-risk pore-clogger. No meaningful pH-related hazards are expected.
