Science
Mechanism of Action
This quaternary ammonium compound carries a strong positive charge, enabling it to electrostatically bind to negatively charged skin and hair. On the skin, it forms a uniform film that smoothes texture and acts as a conditioning barrier to retain moisture.

The Formula
Formulation
Stability
Highly stable across a broad pH range of 2-9, though extreme pH may reduce viscosity. It is heat tolerant up to 80°C and is typically incorporated into the water phase.
Conflicts
- Highly anionic surfactants (may form complexes or precipitate)
- Strongly anionic thickeners like Carbomer (can cause clumping)
- Soap-based systems (at very high concentrations)
Safety
Safety Profile
The CIR Expert Panel (2022) concluded it is safe in current practices when formulated to be non-irritating. European regulations (Annex III) also permit its use, subject to purity criteria for residual acrylamide monomers.
