Oil obtained from the rice plant(oryza sativa) (rice bran oil), which is used as a foodstuff but also in the cosmetics industry. Rice bran oil is obtained from rice bran, which consists of the pericarp, seed coat, aleurone layer and embryo of the rice grain and is obtained when the brown raw rice is husked (polished). Depending on the variety, the bran contains approx. 16-32% oil, which is obtained by solvent extraction and refining. While native pressed rice germ oil is yellow-brownish and has a characteristic odor, the refined rice germ oil we offer as a cosmetic or edible oil is usually light yellow to clear and almost odorless. Very different qualities are available on the market, which differ significantly in the processing steps and their content of gamma-oryzanol (a mixture of phytosterols esterified with ferulic acid, which has an antioxidant effect), lecithins and tocopherols. Completely refined cosmetic rice germ oil usually contains only approx. 0.5-1% gamma-oryzanol absolute, 66% of the previously present tocopherols, no more phospholipids (lecithins), but still 95% of the originally contained phytosterols. Rice germ oil is used to varying degrees in the cosmetics industry. In terms of skin feel, it is a rather light, slightly greasy oil that gives emulsions a pleasantly "moist" and rather non-greasy character.
