Science
Mechanism of Action
Upon neutralization, this crosslinked polymer expands to form a three-dimensional network, effectively trapping water and oil droplets to increase viscosity and stabilize formulations. This network also scatters light, contributing to a blurring effect.

Key findings
- 01 A 25% aqueous dilution was found to be non-irritating and non-sensitizing in a Human Repeated Insult Patch Test with 47 subjects.
- 02 Formulations containing 2% demonstrated low potential for skin irritation and sensitization in clinical HRIPT trials.

Stability
Requires neutralization with a base to achieve maximum viscosity, after which it exhibits high stability across a wide pH range.
Conflicts
- High concentrations of electrolytes/salts
- Cationic ingredients
- Strong acids (unless acid-tolerant grades)
Safety
Safety Profile
Safety is contingent on minimizing residual monomers (like acrylic acid) and ensuring the polymer is not polymerized in benzene.
