Science
Mechanism of Action
As an alkali-swellable emulsion thickener, its carboxylic acid groups ionize and expand upon neutralization with a base. Hydrophobic 'Ceteth-20' side chains then associate, forming a structured network that increases viscosity and stabilizes emulsions through steric hindrance.

Stability
Supplied as an acidic aqueous emulsion, it develops viscosity upon neutralization and is highly stable in high-alkaline systems with good salt tolerance.
Conflicts
- Cationic surfactants
- Highly acidic environments (below pH 6.0)
- High concentrations of divalent salts
Safety
Safety Profile
The CIR Expert Panel found acrylates copolymers safe when formulated to be non-irritating, with strict control over residual monomer levels (typically <20-100 ppm).
