Science
Mechanism of Action
This ingredient reduces water's surface tension due to its amphiphilic structure, enveloping oily impurities for easy rinsing. At higher concentrations, it can disrupt skin barrier lipids.

Dusting Analysis
This ingredient functions as a rinse-off cleansing and foaming agent, where 'dusting' in leave-on formulations is not a relevant concern for efficacy or safety.
The Formula
Formulation
Stability
Stability and viscosity improve as pH increases towards neutral. High pH might impact skin compatibility, and thermal decomposition can cause pH drift in aqueous solutions.
Conflicts
- Cationic surfactants
- Strongly acidic environments
- High electrolyte/salt concentrations
Safety
Safety Profile
The CIR Expert Panel found it safe when formulated to be nonirritating, with irritation being concentration- and pH-dependent. Related salts have been used up to 3%.
