Science
Mechanism of Action
It forms a continuous, flexible, and hydrophobic film on the skin's surface. This barrier reduces trans-epidermal water loss (TEWL), offers water resistance, and extends the wear of cosmetic formulations.

The Formula
Formulation
Stability
Practically insoluble in water in its raw state; requires neutralization with a base (e.g., TEA, KOH, or AMP) to become water-soluble or dispersible.
Conflicts
- Highly acidic environments (may precipitate)
- Strongly cationic ingredients (due to its anionic nature)
- Formulations with very high water content without adequate solvent or neutralization
Safety
Safety Profile
The CIR Expert Panel concluded safety when residual acrylamide monomer does not exceed 5 ppm; most leave-on applications are below 7%.
