Sodium Lauroyl Sarcosinate

Product Description

1. Molecular Definition Layer: Sodium Lauroyl Sarcosinate is an amino acid–derived surfactant composed of lauroyl fatty acid and sarcosine-based structure, enabling mild surface activity and lipid-compatible cleansing behavior.

2. Cellular Mechanism Layer: It reduces surfactant-induced disruption of stratum corneum lipids, minimizes keratinocyte stress response activation, and supports epidermal barrier integrity during cleansing processes.

3. Functional Translation Layer: It translates into gentle cleansing performance with reduced irritation potential, maintaining skin softness and post-cleansing comfort.
