Science
Mechanism of Action
POLYACRYLATE-22 functions by creating a cohesive, continuous film upon application to the skin or hair. As a member of the polyacrylate family, it effectively absorbs water, which is key to its ability to increase the viscosity of aqueous solutions and stabilize oil-in-water emulsions in cosmetic formulations.

Dusting Analysis
No data regarding 'dusting' properties or thresholds for POLYACRYLATE-22 were identified in the research.
The Formula
Formulation
Stability
Optimal performance of polyacrylates, including related Sodium Polyacrylate, is observed in soft water with low salinity, facilitating proper dispersion and full chain elongation. The stability of related polyacrylic acid may be negatively impacted by residual persulfate.
Conflicts
- Hardness ions (can hinder dispersion and chain elongation for related polyacrylates)
- Residual persulfate (potentially detrimental to related polyacrylic acid stability)
Safety
Safety Profile
The CIR Expert Panel concluded that 126 acrylates copolymers, including POLYACRYLATE-22, are safe for use in cosmetics at current concentrations, provided the final formulation is non-irritating. Maximum reported concentrations reach 25% for film-forming applications. Related polymers demonstrated good tolerance in eye irritation tests at concentrations up to 20-30%. While no specific SCCS opinion was found for POLYACRYLATE-22, polyacrylates are recognized by the FDA as indirect food additives, indicating a broad safety profile.
