Formulation
Stability
Supplied as an acidic powder, it requires neutralization with a base (e.g., TEA, NaOH) to become water-soluble. It can also be solubilized into oil systems by neutralizing with long-chain amines.
Conflicts
- Highly acidic environments (may precipitate)
- Cationic ingredients (may cause complexation/instability)
Safety
Safety Profile
The CIR Panel affirmed its safety for cosmetic use, emphasizing formulations must be non-irritating and contain less than 5 ppm residual acrylamide monomer. A 15% solution was found non-sensitizing and non-irritating in HRIPT tests.
