Science
Mechanism of Action
This crosspolymer functions by optimizing the rheological properties of formulations, acting as a gelling agent and texturizer to create smooth, easily spreadable products. It establishes a continuous film on the skin, contributing to enhanced moisture retention and a refined skin feel. Furthermore, it serves as an emulsifier and stabilizer, crucial for maintaining the integrity of oil-in-water systems.

Key findings
- 01 Research demonstrates that concentrations between 0.5% and 5% (w/w) effectively modify viscoelastic properties, with higher percentages (3-5%) yielding gel-like textures. A 3% (w/w) concentration proved optimal for emulsion preparation, balancing viscosity and emulsion stability.
- 02 Safety assessments confirm a non-sensitizing profile for skin at concentrations below 2.25% in Human Repeated Insult Patch Tests (HRIPTs), also showing no eye irritation in HET-CAM assays.

Formulation
Stability
This crosspolymer demonstrates good stability under typical environmental conditions. Its functional groups can undergo hydrolysis within a pH range of 4 to 9, yet it maintains its functionality effectively across this specified pH range and varying temperatures.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed this ingredient safe for cosmetic use at current concentrations, noting its large molecular weight limits skin penetration. Manufacturers are advised to implement current good manufacturing practices (cGMPs) to ensure that potential residual impurities, such as acrylamide, do not exceed 5 ppm in the finished product.
