Science
Mechanism of Action
Its ethylamine oxide units carry a cationic charge that binds to negatively charged keratin, offering adhesion and anti-static effects. Hydrophobic stearyl acrylate segments form a surface film, reducing moisture loss and frizz, while its large molecular weight ensures surface retention.

The Formula
Formulation
Stability
Highly stable in alkaline environments (pH 8-11) and typically supplied as a liquid dispersion (pH 6.5-8.0). It tolerates heat up to 40°C for long-term storage.
Conflicts
- Strongly anionic thickeners may cause complexation
- Highly acidic environments (below pH 4) may affect film flexibility and solubility
Safety
Safety Profile
This large, high-molecular-weight polymer is considered non-toxic and non-penetrating. Formulations should maintain residual monomer levels, such as acrylic acid, below 100 ppm to mitigate potential irritation.
