Science

Mechanism of Action

POTASSIUM ACRYLATES/C10-30 ALKYL ACRYLATE CROSSPOLYMER operates by forming a cross-linked acrylic network that efficiently absorbs water, thereby creating a robust gel matrix. This matrix effectively thickens the formula, suspending ingredients to ensure their uniform distribution. Its unique composition, featuring both hydrophilic and hydrophobic elements, enables it to stabilize emulsions by effectively blending oil and water phases. Additionally, it provides shear-thinning properties for effortless application and a non-greasy skin feel, while contributing to product longevity and forming a protective barrier on the skin.

Stability

Optimal gelling and thickening properties are activated upon neutralization to a pH range of 6.0–7.0. This ingredient significantly enhances emulsion stability, preventing the separation of oil and water components, and contributes to the stability and longevity of cosmetic products by safeguarding sensitive active ingredients. While offering good electrolyte tolerance, some older forms may experience unrecoverable viscosity loss with high concentrations of salts; however, manufacturers are continually developing improved structures.

Synergies

  • Enhances the stability and longevity of active substances within formulations.
  • Improves overall product stability by preventing oil-water phase separation.

Conflicts

  • Significant loss of viscosity in some forms upon the addition of high concentrations of electrolytes (salts).

Safety

Safety Profile

CIR Status
Safe with restrictions
Max tested
5%
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed this ingredient safe for use in current cosmetic practices and concentrations, provided it is not polymerized in benzene. For forms polymerized in benzene, data were insufficient for a general safety determination, necessitating a risk assessment for benzene, with recommended maximum concentrations of 0.4% for leave-on products and 1.1% for rinse-off products. It is generally regarded as non-comedogenic and non-irritating to the skin in typical cosmetic formulations; however, undiluted concentrations have produced minimal to moderate irritation in some studies.
