Science
Mechanism of Action
As a sugar-based surfactant with a high HLB of approximately 13, it reduces surface tension to emulsify oils and debris for easy rinsing. Its unique glucose-derived structure prevents the denaturation of skin proteins, while its molecular interaction with microbial cell walls enhances the permeability of active preservatives, allowing for lower overall preservative concentrations.

Clinical Evidence

Key findings
- 01 NICNAS 2016 safety evaluation confirmed no public health risk in rinse-off applications at concentrations up to 3%.
- 02 In vitro assessments of related amino acid alkyl amides demonstrate zero dermal irritation at levels between 1.85% and 2.05%.

Dusting Analysis
Because it functions primarily as a surfactant and solubilizer rather than an active 'hero' ingredient, it is rarely used at marketing-only 'dusting' levels; it is typically included at functional concentrations to achieve formula stability and foam quality.
The Formula
Formulation
Stability
Highly stable due to a robust amide bond that resists hydrolysis across a broad pH spectrum. It is cold-processable and excellent for stabilizing foam in sulfate-free systems.

Safety
Safety Profile
Safety is concentration-dependent; while the raw 100% concentrate is a severe eye irritant, diluted cosmetic use at or below 3% is considered safe for rinse-off products.
