Science
Mechanism of Action
Operating as a gentle anionic surfactant, Sodium Cocoyl Rice Amino Acids reduces surface tension to efficiently lift dirt, excess oil, and environmental pollutants from the skin. Beyond its cleansing action, it functions as a skin-conditioning and replenishing agent, imparting emollient properties that soften and smooth the complexion. This ingredient is noted for its ability to produce a creamy, delicate foam, enabling effective yet non-irritating cleansing. It actively supports the skin’s natural moisture barrier, enhancing hydration, and can mitigate the potential for irritation from other, more potent surfactants within a formulation.

Stability
While amino acid-based surfactants can exhibit pH sensitivity, often performing optimally at a neutral pH, some demonstrate stability across a broader range. This ingredient is generally water-soluble, facilitating its integration into aqueous systems. It may contribute to pH buffering, helping to maintain a skin-compatible pH environment, typically between 5.0 and 6.5.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed amino acid alkyl amides, including Sodium Cocoyl Rice Amino Acids, safe for use in cosmetic formulations, provided they are formulated to be non-irritating. This specific ingredient is recognized as safe and is not associated with drying or sensitizing effects. There is no specific SCCS opinion available. A component, rice protein, holds FDA GRAS (Generally Recognized As Safe) status for food applications.
