Science
Mechanism of Action
This polymer enhances cosmetic formulations by efficiently absorbing water, which significantly increases viscosity and refines product texture for a desirable sensory experience. On the skin, its substantial molecular weight and cross-linked structure enable it to form a protective, non-penetrating film. This film helps to diminish transepidermal water loss (TEWL) and reinforce the skin's natural moisture balance, providing surface-level hydration.

Dusting Analysis
When handled in its powder form, inhalation should be carefully avoided due to potential respiratory irritation.
The Formula
Formulation
Stability
Optimal thickening efficacy is observed within a pH range of 6.0 to 9.0, with enhanced performance typically above pH 7. It disperses most effectively in soft water with minimal salinity. High concentrations of hardness ions, such as Ca+2, can lead to precipitation. Exposure to temperatures exceeding 100°C may compromise its 3D network structure and swelling capacity.
Conflicts
- High salinity
- Hardness ions (e.g., Ca+2)
- Residual acrylic acid levels above 300 PPM
- Temperatures exceeding 100°C
Safety
Safety Profile
The CIR Expert Panel considers acrylates copolymers, including similar polymers, safe for cosmetic applications when formulated to prevent irritation. Its large molecular size generally restricts skin penetration, thereby minimizing irritation. A critical restriction is maintaining residual acrylic acid below 300 PPM, as higher levels may potentially induce skin irritation. Inhalation of the powder form must be avoided.
