Formula IngredientEmollientINCI: Oryza Sativa Lipids
Oryza Sativa Lipids are the lipid fraction isolated from rice (Oryza sativa L.), primarily composed of fatty acids including oleic acid (~38%), linoleic acid (~34%), palmitic, and stearic acids, along with antioxidants such as gamma-oryzanol, tocopherols, and tocotrienols. They function as an emollient and skin-conditioning agent, softening and smoothing the skin while reinforcing the lipid barrier to reduce transepidermal water loss. The balanced fatty acid profile closely resembles skin's natural lipids, making them well tolerated and readily absorbed.

Undiluted rice bran lipids were not irritants in animal skin tests, and were at most mildly irritating in clinical studies at cosmetic concentrations. Rice Bran Oil was not a sensitizer in guinea pig testing. No EU CosIng Annex II or III restrictions apply.
A mixture of rice bran oil and rice germ oil had a UV absorption maximum at 315 nm but was not phototoxic in a dermal exposure assay. No increased sun sensitivity is expected from topical use of oryza sativa lipids.
Animal reproductive studies (three-generation oral dosage at 10% rice bran oil) showed no adverse effects on conception rates, birth weights or litter sizes. The Cosmetic Ingredient Review (CIR) Expert Panel concluded rice-derived ingredients are safe as cosmetic ingredients at described concentrations. Topical use is considered low risk during pregnancy.
