Science
Mechanism of Action
This protein acts as a potent antioxidant, effectively neutralizing free radicals to defend the skin from environmental stressors. It demonstrates anti-tyrosinase and anti-melanogenic properties, aiding in the reduction of hyperpigmentation and promoting a more uniform skin tone. By forming a protective film, it enhances the skin's ability to retain moisture, ensuring sustained hydration. Furthermore, Oryza Sativa Bran Protein stimulates fibroblast growth and supports the synthesis of collagen and elastin, which helps diminish the appearance of wrinkles and improves skin firmness. It also strengthens the skin's barrier function, normalizes keratinocyte processes, and possesses antimicrobial activity that can inhibit acne-associated bacteria, alongside potential anti-inflammatory effects.

Formulation
Stability
Rice bran protein exhibits minimum solubility around its isoelectric point of pH 4. However, its solubility significantly improves at higher pH levels, specifically increasing as pH is raised from 8 to 12. Deamidated forms of the protein show enhanced solubility across various temperatures and pH values, with films formed at pH 10-12 becoming fully water-soluble when heated to 120°C.
