Made of carbon, hydrogen, oxygen, and nitrogen, and sometimes sulfur and phosphorus., and Hydrolyzed Rice Bran Protein may also be used in cosmetics and personal care products. The ingredients made from rice may be used in a wide varity of cosmetics and personal care products.

Scientific Facts

Oryza sativa is one species of rice. Rice is the world’s largest crop and serves as a staple food for a large part of the world’s human population. Oryza Sativa (Rice) Bran Oil is a light yellow oil expressed from rice bran.

Crude Rice Bran Oil is non-edible due to the large amounts of fatty acids and waxes present in the mixture. The fatty acids and waxes are removed to obtain refined Rice Bran Oil, which is used extensively in cooking in Asian countries.

Safety Information

The Food and Drug Administration (FDA) permits Rice Bran Wax to be directly added to food. Rice Bran Wax is also on the list of indirect food additives that may be used as releasing agents. The safety of the ingredients made from rice has been assessed by the Cosmetic Ingredient ReviewThe Cosmetic Ingredient Review (CIR) was established in 1976 as an independent safety review program for cosmetic ingredients. The CIR Expert Panel consists of independent experts in dermatology, toxicology, pharmacolgy and veterinary medicine. The CIR includes participation by the U.S. Food & Drug Administration and the Consumer Federation of America. (CIR) Expert Panel. The CIR Expert Panel evaluated the scientific data and concluded that Oryza Sativa (Rice) Bran Oil, Oryza Sative (Rice) Germ Oil, Rice Bran Acid, Oryza Sativa (Rice) Bran Wax, Hydrogenated Rice Bran Wax, Oryza Sativa (Rice) Bran Extract, Oryza Sative (Rice) Extract, Hydrolyzed Rice Bran Extract, Hydrolyzed Rice Extract, Oryza Sativa (Rice) Germ Powder, Oryza Sativa (Rice) Bran, Oryza Sativa (Rice) Starch, Hydrolyzed Rice Protein, and Hydrolyzed Rice Bran Protein were safe as a cosmetic ingredient in the current practices of use and concentrations as reflected in the safety assessment.

CIR Safety Review: Information on phytosterolSterols derived from plants. gamma-oryzanol, found in rice were included throughout the CIR report. To facilitate the review, the ingredients derived from rice were placed into four groups, oils, fatty acids and waxes; extracts; bran, starch and powder; and proteins.

The available data, including dermal irritation and sensitization tests and mutagenicity studies did not suggest any toxicity of the oils, fatty acids and waxes (Oryza Sativa (Rice) Bran Oil, Oryza Sative (Rice) Germ Oil, Rice Bran Acid, Oryza Sativa (Rice) Bran Wax, and Hydrogenated Rice Bran Wax). The CIR Expert Panel also noted that the fatty acidA natural organic compound that consists of a carboxyl group (oxygen, carbon and hydrogen) attached to a chain of carbon atoms with their associated hydrogen atoms. The chain of carbon atoms may be connected with single bonds, making a ‘saturated’ fat; or it may contain some double bonds, making an ‘unsaturated’ fat. The number of carbon and hydrogen atoms in the chain is what determines the qualities of that particular fatty acid. Animal and vegetable fats are made up of various combinations of fatty acids (in sets of three) connected to a glycerol molecule, making them triglycerides. composition of the ingredients in the oils, fatty acids, and waxes group included fatty acids that were previously determined safe.

Based on composition information and skin testing (irritation and sensitization tests) the CIR Expert Panel were also able to conclude that the extracts (Oryza Sativa (Rice) Bran Extract, Oryza Sative (Rice) Extract, Hydrolyzed Rice Bran Extract, and Hydrolyzed Rice Extract), bran, starch, and powder (Oryza Sativa (Rice) Bran, Oryza Sativa (Rice) Starch,Oryza Sativa (Rice) Germ Powder), and the proteins (Hydrolyzed Rice Protein, Hydrolyzed Rice Bran Protein) could be safely used in cosmetics and personal care products. The CIR Expert Panel noted that trace amounts of pesticides and polychlorinated biphenyls (PCBs) have been reported in Rice Bran Oil used for cooking. They indicated that pesticides and PCBs should not exceed currently reported levels for rice-derived ingredients in cosmetics and personal care products.
