SODIUM ACRYLATE/METHALLYLSULFONATE/METHOXY PEG-48 METHACRYLATE/SUCROSE COPOLYMER.

Questionable CAS 156175-47-2 / CHELATING

This copolymer acts as a potent chelating agent, effectively binding metal ions that can degrade cosmetic product stability and appearance. Beyond chelation, it also contributes to formulation texture, offering viscosity control, film-forming properties, and emulsion stabilization.

Chelating Viscosity Control Film-forming Emulsion Stabilization

Science

Operating primarily as a chelating agent, this ingredient sequesters free metal ions within formulations, preventing their detrimental effects on product integrity and aesthetic qualities. Its polymeric structure further enhances cosmetic stability by modulating viscosity, aiding in film formation, and stabilizing emulsions.

Stability

Its primary function as a chelating agent is pivotal for maintaining formulation stability by actively complexing with various metal ions.

Conflicts

  • This substance is incompatible with formulations seeking organic or natural certifications due to its ethoxylated components (PEG), which are associated with potential ethylene oxide contamination, a compound classified as a carcinogen.

Safety

CIR Status
Safe with restrictions
Sensitization risk Unknown

The CIR Expert Panel generally considers acrylate copolymers safe when appropriately formulated to be non-irritating. However, this specific ingredient has been labeled 'Muy Dudoso' (Very Doubtful) by certain sources, primarily due to the presence of ethoxylated (PEG) moieties. These components are typically restricted in organic or natural certified cosmetics over concerns about residual ethylene oxide, a recognized carcinogen.

Our Assessment

Questionable

While providing beneficial chelating and formulation-stabilizing properties, the presence of ethoxylated components (PEG) and its classification as 'Muy Dudoso' by some authorities warrant caution, particularly for formulations aiming for organic or natural certification.
