Science

Mechanism of Action

Rice amino acids demonstrate robust skin penetration, delivering intense hydration and restoring optimal moisture balance by attracting and retaining water as hygroscopic compounds. They actively reinforce the skin barrier, providing defense against external aggressors like pollution and UV radiation. This ingredient stimulates collagen synthesis, enhancing skin elasticity and visibly reducing the appearance of fine lines. Concurrently, it offers significant antioxidant protection, calms irritation and redness through anti-inflammatory properties, and contributes to a brighter, more even skin tone by addressing dark spots. Furthermore, it aids in regulating sebum production, making it beneficial for oily or acne-prone skin, and supports natural desquamation for a smoother skin texture. Fermented forms, yielding smaller peptides, are observed to offer enhanced skin barrier penetration and collagen stimulation.

Stability

Rice amino acids integrate seamlessly with other cosmetic actives. While specific pH ranges for rice amino acids are not detailed, related rice protein isolates exhibit low solubility between pH 4-7, with solubility significantly increasing as pH approaches 9. Optimal stability for succinylated rice glutelin emulsions is observed at pH 9, with highest oxidative stability at pH 7. Formulations incorporating fermented rice ingredients tend to be stable and pH-balanced.

Safe as used
Sensitization risk Low

The CIR Expert Panel has deemed alpha-amino acids, a category encompassing rice amino acids, and other rice-derived ingredients like Hydrolyzed Rice Protein, safe for use in cosmetics under current practices. Non-human in vitro studies indicate no dermal or ocular irritation. While allergic reactions are exceptionally rare, a precautionary patch test is advised for individuals with highly sensitive skin. No specific SCCS or FDA status was identified.
