What it is
Oryzanol is a naturally occurring mixture of ferulic acid esters of sterols and triterpene alcohols, obtained from rice bran oil. It is valued for its antioxidant character and ability to condition the skin, and ferulic acid derivatives are widely studied for their ability to absorb UV light and stabilize formulas. In sunscreens it is used as a supporting antioxidant and conditioning agent rather than as an approved UV filter.
Safety & warnings
Oryzanol is generally well tolerated and is not a commonly cited allergen. It is used at low levels and is broadly regarded as low-irritation.
Origin & sourcing
Natural; isolated from rice bran (Oryza sativa) oil.
