ORYZA SATIVA (RICE) BRAN OIL
Natural and essential oils are commonly extracted from parts of the plant such as leaves, seeds, nuts, and flowers. Rice bran, on the other hand, is extracted from the by-product of rice grain, the bran called chaff. This oil contains linoleic, oleic and alpha-linolenic unsaturated fatty acids which moisturize the skin. It also contains fat soluble compounds such as tocopherols, tocotrienols, carotenoids and gamma-oryzanol. Rice bran is the only vegetable that contains gamma-oryzanol, a potent antioxidant more powerful than vitamin E. Research shows the content of gamma-oryzanol is ten folds than that of vitamin E in rice bran as well.
Uses:
- Emollient
- Antioxidant
- Softens and smooths the skin
- Sooth
