About
Rice bran sterols — a phytosterol-rich fraction of rice bran (including gamma-oryzanol) used to support the skin barrier. Well-tolerated and widely used in modern skincare.
Oryza sativa (rice) bran sterol is a purified phytosterol fraction isolated from rice bran oil, dominated by beta-sitosterol, campesterol, and the ferulate ester gamma-oryzanol. In cosmetics it functions as a skin-conditioning and antioxidant agent and as a plant-based alternative to cholesterol for barrier-repair claims. Typical use levels are 0.1-2%. Phytosterols as a class have a long CIR safety record (safe as used in cosmetics) and EU CosIng lists the ingredient without restriction. Main real-world concerns are oxidation of the ester component in poorly preserved systems and, rarely, cross-reactivity in users with severe grain allergies. No IARC classification; no GHS hazard pictograms.
