Science
Mechanism of Action
Functions by reducing water surface tension below 45 mN/m, enabling foam generation at the air-water interface while emulsifying sebum and debris at oil-water interfaces. The C12-15 carbon chain length optimizes the balance between cleansing efficacy and foam stability for thorough but manageable cleansing action.
Research
Clinical Evidence
High confidence10%
Key findings
- 01 Core surfactant studies demonstrate surface tension reduction below 45 mN/m at 0.5% with high foaming capacity in rinse-off applications
- 02 Structured liquid formulation research shows effective use at 1-15% as primary anionic surfactant with improved conditioning agent deposition

Dusting Analysis
As a functional surfactant requiring meaningful concentrations for efficacy, dusting is not applicable to this ingredient
The Formula
Formulation
Stability
Maintains stability in acidic to neutral conditions. Above pH 9.0, ammonium salts may release ammonia gas. Below pH 3.0, sulfate ester hydrolysis can occur.
Synergies
- Conditioning agents for improved skin deposition
- Other anionic and non-ionic surfactants for cleansing systems
Conflicts
- Cationic polymers
- Strongly alkaline ingredients
- Highly ethoxylated non-ionic surfactants
Safety
Safety Profile
CIR approval applies to rinse-off products; leave-on applications should use lower concentrations. Generally less irritating than sodium lauryl sulfate due to larger ammonium counter-ion structure.
