About
A very large polyethylene glycol polymer used as an emulsifier and humectant in cosmetic and pharmaceutical formulations.
PEG-135 is a high molecular weight polyethylene glycol polymer with approximately 135 ethylene oxide units, producing a large hydrophilic molecule that is poorly absorbed through the skin. It is not listed in EU Annex II (prohibited substances) or Annex III (restricted substances), indicating no specific safety concerns at current use levels. The high molecular weight significantly limits systemic exposure potential.
