Science
Mechanism of Action
As an anionic surfactant and water-in-oil emulsifier, it works by integrating with the skin's natural lipid barrier to minimize trans-epidermal water loss (TEWL). It facilitates a smooth application experience by preventing the 'soaping' effect in emulsions while simultaneously attracting and holding moisture within the stratum corneum.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical evaluation at 3.0% indicates significant enhancement in hydration and sensory performance in both anhydrous and emulsion-based systems.
- 02 Safety testing at 7.0% demonstrated zero irritation across multiple cohorts, though certain 2.5% hair-care formulations suggested potential for irritation, highlighting the importance of proper stabilization.
Transparency
Dusting Analysis
Typically utilized at functional levels between 2% and 5% to achieve emulsification; levels below 1% in heavy creams may indicate it is being used for label claims rather than structural integrity.
