Science
Mechanism of Action
This ingredient functions as a highly efficient viscosity-controlling agent and thickener. As a HASE polymer, it provides high thickening efficiency and exhibits shear-thinning rheology, which allows for smooth application while maintaining product stability and particle suspension in its resting state, thus improving overall texture and performance.

Dusting Analysis
POLYACRYLATE-33 primarily acts as a viscosity modifier and thickener, not an active ingredient with specific efficacy thresholds typically associated with 'dusting' or clinical efficacy claims related to direct skin benefits.
The Formula
Formulation
Stability
For crystal-clear formulations with high clarity and excellent salt tolerance, the final pH should be adjusted to above 6.3, with optimal polymer neutralization typically achieved at a pH of 6.5.
Conflicts
- Amphoteric surfactants above 3.0% w/w (for maintaining crystal-clear formulations)
- High surfactant content above 13% w/w (when intending to suspend standard beads and particles effectively)
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel, in a 2002 assessment including Polyacrylate-33 and related acrylates, concluded these ingredients are safe for use in cosmetics when formulated to avoid irritation. It is generally considered well-tolerated.
