Science
Mechanism of Action
The molecule features positively charged amino groups that are electrostatically attracted to negatively charged, damaged sites on the hair cuticle or skin surface. This selective bonding allows it to form a flexible, non-occlusive film that reduces static and fills structural irregularities while remaining resistant to premature rinsing.

Key findings
- 01 A 24-week longitudinal study demonstrated that a regimen utilizing 0.5-5.0% of this ingredient alongside antioxidants significantly enhanced hair anchorage, resulting in an average retention of 2,400 additional fibers.
- 02 Comparative safety and performance assessments by the CIR indicate that this modified silicone provides superior conditioning on damaged surfaces compared to traditional dimethicone due to its targeted deposition mechanism.

Dusting Analysis
While often used at higher levels in rinse-off products, functional benefits for surface smoothing and scalp health begin at 0.5%. Levels below 0.1% in leave-on repair formulas may indicate 'label dressing' rather than active performance.
The Formula
Formulation
Stability
Highly stable across a pH spectrum of 3.5 to 9.0; however, its hygroscopic nature requires airtight storage to prevent atmospheric moisture absorption which can cause raw material haziness.
Synergies
- Antioxidants
- Cyclomethicone
- Cationic surfactants
Conflicts
- Anionic surfactants (may reduce foam volume)
- Low-shear aqueous mixing
Safety
Safety Profile
Due to its high molecular weight, the ingredient is not absorbed through the skin, minimizing systemic exposure concerns.
