About

A long-chain PEG-2000 ethoxylated bilirubinamide analogue with very limited safety information, posing similar concerns to its shorter-chain PEG-36 counterpart.

Methoxypolyethylene glycol 2000 bilirubinamide shares the same bilirubinamide core as the PEG-36 variant but carries a substantially longer polyethylene glycol chain (average MW 2000). High-MW PEG derivatives are generally considered low risk for systemic absorption due to their size, but concerns regarding residual monomers, peroxidation of PEG chains on storage, and unknown ecological profiles persist. No EU CosIng entry or safety assessment was found for this specific ingredient.

Skin benefits

  • Potential antioxidant activity from bilirubin scaffold
  • High MW PEG may contribute to film-forming humectant effect

Known concerns

  • No established EU safety assessment or authorised use
  • Potential for PEG peroxidation by-products over time
  • Residual monomer content from polymerisation
