Science
Mechanism of Action
By utilizing a dual-affinity structure—a hydrophobic C12-16 alkyl chain and a hydrophilic polyoxyethylene chain (5 moles)—it lowers interfacial tension to create stable oil-in-water emulsions. It organizes into micelles that encapsulate sebum and environmental debris, allowing them to be rinsed away without disrupting the skin's lipid barrier.

Key findings
- 01 Clinical dermal testing confirmed that while undiluted forms may be reactive, aqueous solutions at 25% exhibit significantly lower irritation potential, supporting its safety in finished formulations.
- 02 Technical evaluations demonstrate that concentrations between 1-5% effectively stabilize emulsions and improve the solubility of hydrophobic actives without the irritation typical of anionic surfactants.

Dusting Analysis
This is a functional excipient rather than a marketing active; its presence at low concentrations is typically for emulsion stabilization rather than consumer-facing claims.
The Formula
Formulation
Stability
Highly stable across a broad pH spectrum and resistant to hard water. With an HLB value of approximately 10.5, it is optimized for oil-in-water (O/W) systems.
