The Formula
Formulation
Stability
This copolymer demonstrates excellent stability and thickening properties, ideally within a pH range of 6.3 to 8.0. It is miscible with ethanol or water when neutralized and can be solubilized in oil systems with long-chain amines.
Conflicts
- Cationic raw materials (compatibility requires evaluation)
- High concentrations of non-polar products (may decrease solubility)
- Under-neutralization (may lead to grittiness)
Safety
Safety Profile
The CIR Expert Panel concluded safety with restrictions, primarily recommending acrylamide monomer concentration not exceed 5 ppm. European regulations specify maximum residual acrylamide content for cosmetic products.
