Science
Mechanism of Action
Defatted Rice Bran functions primarily as a robust antioxidant, actively neutralizing free radicals with its high concentrations of ferulic acid, vitamin E, and gamma-oryzanol, thereby mitigating oxidative stress and premature aging. It supports an even skin tone by reducing melanin overproduction, assisting in the visual reduction of dark spots. The ingredient enhances moisture retention through natural emollient properties, reinforcing the skin's moisture barrier and preventing transepidermal water loss. Its natural phytic acid provides gentle exfoliation, alongside promoting collagen and elastin synthesis, which contributes to improved skin texture and reduced appearance of fine lines. Furthermore, it calms stressed or reactive skin via anti-inflammatory B vitamins and phytocompounds, while offering photoprotective benefits against radiation-induced damage.

The Formula
Formulation
Stability
Defatted Rice Bran (DRB) consists of approximately 66% carbohydrates and 15% proteins, exhibiting high water absorption capacity post-oil extraction. Its extracts are readily water-soluble. Optimal solubility and emulsifying capacity for its protein components are observed between pH 4.0 and pH 9.0, with peak activity around pH 9.0. Due to its naturally coarse texture, fine milling or targeted extraction methods are typically required to ensure optimal stability and seamless integration into cosmetic formulations, preventing physical compatibility issues.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of rice-derived ingredients, including Rice Bran Extract, for cosmetic use under typical conditions. These ingredients are broadly recognized as non-allergenic, non-irritating, and hypoallergenic in topical applications, with no reported phototoxicity from clinical experience. While a specific maximum concentration for 'Defatted Rice Bran' is not specified, the safety assessment encompasses the general range of uses. There is no dedicated SCCS assessment for this specific ingredient, and FDA GRAS status for food applications does not directly translate to cosmetic use limits.
