Science
Mechanism of Action
As a hydrophobically modified polymer, it forms a 3D network in water, effectively thickening aqueous solutions and stabilizing oil droplets without traditional emulsifiers. This structure delivers a cooling 'quick-break' sensory experience upon application.

The Formula
Formulation
Stability
This pre-neutralized polymer thickens without needing additional base. It is sensitive to pH extremes; below 4.0 may cause viscosity loss, and above 9.0 may release ammonia gas. Electrolytes and salts can significantly reduce its viscosity.
Conflicts
- Electrolytes and salts
- Cationic surfactants
- Polyvalent metal ions
- High concentrations of sodium chloride
Safety
Safety Profile
Deemed safe for use at current concentrations provided it is formulated to be non-irritating. Residual acrylamide content should be kept to a minimum (typically below 2-5 ppm).
