POLYACRYLATE CROSSPOLYMER-15.

Valuable / EMULSION STABILISING, FILM FORMING

Polyacrylate Crosspolymer-15 is a synthetic polymer engineered to enhance formulation stability and texture in skincare products. It functions as an emulsion stabilizer and creates a protective film, contributing to lightweight, non-sticky product consistencies. This ingredient is crucial for maintaining the integrity and sensory appeal of various cosmetic preparations.

Science

Mechanism of Action

This polymer acts as an effective rheology modifier, thickener, and stabilizer, crucial for achieving optimal product consistency and stability. It possesses the capacity to gel water, enabling the stable suspension of oil droplets and ensuring the uniform distribution of active ingredients throughout a formulation. Upon application, it forms a fine, protective film on the skin, which assists in retaining moisture and thereby supporting skin hydration.

Stability

Gels formulated with Polyacrylate Crosspolymer-15 exhibit robust stability across a broad pH range from 2.0 to 8.0. This polymer demonstrates high resistance to electrolytes and is compatible with common active ingredients such as hyaluronic acid, glycolic acid, mandelic acid, retinoids, and antioxidants without adverse chemical reactions. For cream-gel production, its incorporation into the oil phase (at warm or cold temperatures) facilitates effective emulsification and overall product stabilization.

Synergies

  • Other thickeners (e.g., gums, pectins, cellulose derivatives) for increased stability and viscosity.
  • Fatty alcohols (e.g., cetyl alcohol, cetearyl alcohol) to enhance texture and skin feel.
  • Anionic and nonionic surfactants to improve viscosity and foam density.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has determined that crosslinked alkyl acrylates, including Polyacrylate Crosspolymer-15, are safe when not polymerized in benzene. Data for ingredients polymerized in benzene were insufficient to determine safety. A related ingredient, Polyacrylate Crosspolymer-6, is not subject to use restrictions under European Union cosmetic regulations.
