Science
Mechanism of Action
This botanical ingredient acts as a gentle, yet effective, surfactant, characterized by its excellent biodegradability and inherent affinity for the skin. Its primary mechanism involves regulating skin moisture content, providing a moisturizing effect that leaves the skin feeling supple post-cleansing. The L-arginine component further enhances these benefits by functioning as a humectant to attract and retain moisture, promoting tissue repair, supporting collagen synthesis, enhancing microcirculation, and offering antioxidant protection. Notably, it can also mitigate potential irritation when co-formulated with other detergents.

Safety
Safety Profile
The CIR Expert Panel concluded that α-amino acids, including Arginine, are safe for cosmetic use up to 18% concentration. Amino acid alkyl amides, a broader category likely encompassing Arginine Cocoate, are also considered safe under current cosmetic practices when formulated to be non-irritating. L-arginine itself is generally recognized as safe (GRAS) by the FDA in direct food additives and is approved for use in various drug products, indicating a robust safety profile.
