Science
Mechanism of Action
This quaternary ammonium compound utilizes a permanent positive charge to anchor itself to the naturally negative surface of the skin and hair. This 'substantive' binding creates an ultra-thin, breathable protective film that smooths the stratum corneum, neutralizes static, and significantly reduces surface friction for improved glide.
Research
Clinical Evidence
High confidence0.25%
Key findings
- 01 Established as the safety ceiling for leave-on applications to ensure no irritation while maintaining film-forming benefits.
- 02 Demonstrated efficacy in stabilizing wax and oil dispersions, providing primary emulsification without the tackiness associated with shorter-chain quats.
Transparency
Dusting Analysis
Because it is effective at very low concentrations (safety-capped at 0.25% for leave-on products), presence at 0.1% is functional and not considered dusting.
The Formula
Formulation
Stability
Highly stable in acidic environments; its C22 behenyl chain provides superior hydrophobicity, making it exceptionally effective for oil-in-water emulsions.
Synergies
- Fatty alcohols
- Non-ionic surfactants
- Silicones
Conflicts
- Anionic surfactants (SLS/SLES)
- Carbomer thickeners
- Soaps
- Nitrates
Safety
Safety Profile
The 0.25% restriction is specifically for leave-on products; rinse-off products may utilize higher concentrations if formulated for non-irritancy.
