Science
Mechanism of Action
It thickens via two synergistic mechanisms: charge-induced polyelectrolytic chain extension upon neutralization and hydrophobic association, which builds a network with other formulation components.

Key findings
- 01 Functions as an effective suspending agent and thickener for oily conditioning agents in anionic shampoo systems (0.15% - 5%).
- 02 Provides 'no flow' behavior and high stability in styling gels (0.5% - 3%) when combined with carbomer-type thickeners.

The Formula
Formulation
Stability
Supplied as a low-viscosity liquid emulsion, it thickens instantly upon neutralization. It is salt-tolerant, shear-tolerant, and compatible with hydrogen peroxide, but loses viscosity below pH 5.5-6.0.
Synergies
- Carbomer-type thickeners
- Nonionic, anionic, and zwitterionic surfactants
Conflicts
- Highly acidic environments (below pH 5.5-6.0)
- Some strong cationic surfactants
Safety
Safety Profile
The CIR Expert Panel concluded it is safe when formulated to be non-irritating for leave-on dermal products up to 25%. Residual monomer levels are typically <100 ppm.
