Mechanism of Action
As a key component of the skin's natural moisturizing factors (NMF), these amino acids help regulate skin hydration and pH. Derived from pea protein, it functions as a humectant, effectively drawing moisture into the skin and establishing a protective barrier to mitigate transepidermal water loss. This action results in improved skin texture, increased suppleness, and a visibly plumper appearance. Furthermore, its rich amino acid profile, including lysine and proline, supports collagen production, which is crucial for maintaining skin elasticity and minimizing the visibility of fine lines and wrinkles. It also provides antioxidant benefits, aiding in the combat against oxidative stress.

The Formula
Formulation
Stability
Pea protein isolates, the source of these amino acids, demonstrate solubility ranging from 30-40% at pH 4-5 and 40-70% at pH 6-8. Functionality and solubility can be compromised by denaturation at alkaline pH values above 10. As a surfactant, it is expected to disperse in both aqueous and oil phases, and should be precisely formulated to ensure non-irritating properties.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed amino acid alkyl amides, including this ingredient, safe for cosmetic use when formulated to be non-irritating. Manufacturers are advised to minimize residual peptides and ensure that free diethanolamine (DEA) levels do not surpass 0.64% if triethanolamine (TEA) is present in the formulation. No specific SCCS or FDA status was identified in the research data.
