Science
Mechanism of Action
With their low molecular weight, Oat Amino Acids readily penetrate the stratum corneum, delivering hydration deep within the skin layers. They act as humectants, drawing and retaining moisture, and contribute to the skin's natural moisturizing factors. Furthermore, these amino acids help buffer skin pH, support the integrity of the skin barrier, and soothe irritated skin. As foundational components of proteins, they also contribute to cellular repair, improve skin elasticity, and exhibit properties that can reduce inflammation.

Formulation
Stability
The raw material demonstrates optimal stability within a pH range of 4-5. For emulsion formulation, it should be incorporated into the water phase at temperatures below 40°C (104°F). While higher pH (above 8, especially 9-10) can increase the solubility of parent oat proteins, maintaining a pH above 9.5 for extended periods may lead to protein denaturation and alteration of the amino acids.
Safety
Safety Profile
The CIR Expert Panel has determined that alpha-amino acids, including those derived from oat, are safe for cosmetic use within standard practices and concentrations, provided they are formulated to be non-irritating and non-sensitizing. The 'L-' amino acid forms are also recognized as Generally Recognized As Safe (GRAS) direct food additives by the FDA.
