Science
Mechanism of Action
It creates a thin, continuous film on skin or hair to provide smoothing, moisture occlusion, and improved water resistance. It also stabilizes emulsions by increasing the viscosity of the aqueous phase.

The Formula
Formulation
Stability
Highly stable across a broad pH range of 4-9, it is resilient to high shear processing and maintains stability in polar organic solvents.
Conflicts
- High concentrations of electrolytes/salts (can cause viscosity loss)
- Cationic surfactants
- Strongly acidic environments (below pH 4.0 may cause precipitation)
Safety
Safety Profile
The CIR deems acrylates copolymers safe when formulated to be non-irritating. Residual monomer levels, such as acrylic acid, should be kept at technically feasible low levels to prevent potential sensitization.
