Science
Mechanism of Action
As an acylated derivative of hydrolyzed silk protein, Lauroyl Silk Amino Acids possess a small particle size, enabling effective penetration into the dermal layers. It acts as a highly hygroscopic humectant, actively drawing and binding moisture to the skin, thereby establishing a robust moisture-binding barrier. Furthermore, it interlaces with the skin's inherent proteins, such as keratin, to maintain optimal hydration and form a protective surface. The amino acid components, particularly the sericin, contribute to these moisturizing effects through their abundant hydroxyl groups. This action supports improved skin elasticity and can contribute to a reduction in the visible appearance of fine lines by supporting the underlying collagen structure and significantly boosting moisture retention.

Stability
For optimal integration into cosmetic formulations, it is recommended to incorporate Lauroyl Silk Amino Acids during the cool-down phase below 110°C in heated processes, or directly into the water phase for cold-process formulations. Specific pH stability data for this ingredient within cosmetic contexts are currently not available.
Safety
Safety Profile
The CIR Expert Panel determined in September 2013 that amino acid alkyl amides, including Sodium Lauroyl Silk Amino Acids, are safe when used in cosmetic practices, provided they are formulated to be non-irritating. A slight irritant response was observed with sodium lauroyl silk amino acids at a concentration of 0.5% using the HET-CAM method, suggesting careful formulation is key to minimize potential irritation.
