Science
Mechanism of Action
This ingredient forms a continuous film on the skin or hair, improving water resistance and locking in moisture. As a rheology modifier, it thickens formulations by expanding polymer chains upon neutralization, which increases viscosity and suspends insoluble particles effectively.

Key findings
- 01 Demonstrates excellent suspending, stabilizing, and thickening properties in surfactant-based cleaning products at 1-5% concentration.
- 02 Considered safe for use up to 25% in leave-on dermal products, where it acts as a film former without significant toxicity.
- 03 Proven safe for use in nail formulations at concentrations as high as 98.6%.

The Formula
Formulation
Stability
Typically supplied as a low-viscosity aqueous emulsion, it achieves maximum thickening when neutralized with a base to a pH above 6.5. It remains stable across a wide temperature range but must be protected from freezing to prevent irreversible demulsification.
Conflicts
- Cationic surfactants
- Strong electrolytes/high salt concentrations
- Low pH environments
Safety
Safety Profile
Deemed safe in current practices and concentrations when formulated to be non-irritating. Residual monomers (e.g., acrylic acid) are strictly controlled below 20-1000 ppm to minimize any potential for sensitization.
