Oryzanol
What is Oryzanol?
Oryzanol, also called gamma-oryzanol, originates from rice bran oil, specifically its unsaponifiable fraction. This natural lipid-soluble compound consists of ferulic acid esters linked to plant sterols and triterpene alcohols, such as cycloartenol and 24-methylene-cycloartanol ferulates. In cosmetics, it features in moisturizers, sunscreens, hair conditioners, and styling products. It works by creating a protective barrier on skin and hair surfaces, enhancing moisture retention and smoothness. Its antioxidant capacity neutralizes free radicals from oxidation, while antistatic effects improve hair manageability by boosting conductivity and minimizing flyaways. In formulations, it stabilizes emulsions and contributes to product texture without greasiness.
