The Formula
Formulation
Stability
This ingredient is stable across a broad temperature range and highly shear-resistant. Being anionic, it often requires neutralization (e.g., with AMP) to form clear solutions, thickening effectively up to pH 11.
Conflicts
- Cationic ingredients
- Nitrosating systems (risk of nitrosamine formation)
- Strong electrolytes (may reduce viscosity in some variants)
Safety
Safety Profile
The CIR Expert Panel deems it safe as used, with a crucial restriction: residual acrylamide monomer must not exceed 5 ppm. It should not be used with nitrosating systems to prevent nitrosamine formation.
