Science
Mechanism of Action
This ingredient functions through ionic attraction; its positively charged hydroxypropyltrimonium groups anchor to the negatively charged keratin on the skin's surface. During the rinsing process, it undergoes coacervation—a liquid-liquid phase separation—which allows it to encapsulate and deposit lipid-replenishing emollients and other active ingredients directly onto the skin while reducing surface friction.

Key findings
- 01 Comparative sensory evaluations indicate that at concentrations of 0.1-1.5%, this ingredient provides superior wet/dry conditioning and higher coacervate formation than Polyquaternium-10.
- 02 Technical data shows that 0.5% in cleansing formulations significantly stabilizes foam and enhances post-wash skin feel compared to standard cationic guars.
Transparency
Dusting Analysis
Because its primary function is sensory enhancement and active deposition rather than a primary 'active' claim, it is rarely 'dusted' at sub-functional levels. However, concentrations below 0.1% may fail to provide the characteristic silky after-feel.
The Formula
Formulation
Stability
Highly stable across a broad range (pH 4–12), though peak clarity and viscosity development are best achieved between pH 4.0 and 8.0. In powder form, it requires acidification to hydrate fully.

Safety
Safety Profile
Reviewed as safe by the CIR Expert Panel. While styling products utilize up to 2.0%, some regulatory bodies like Health Canada suggest a 0.4% limit for specific rinse-off categories.
