About

A higher molecular weight PPG-quaternary ammonium compound with longer PEG chains, providing enhanced substantivity compared to lower PPG analogs.

PPG-40 Diethylmonium Chloride shares the same core diethylmethylammonio structure as PPG-9 and PPG-25 analogs with a longer PPG chain (PPG-40), increasing hydrophobic character. EU Regulation 1223/2009 permits quaternary ammonium compounds without specific restriction entries, with the longer polymer chain providing enhanced substantivity in conditioning formulations.

Skin benefits

  • Enhanced substantivity for long-lasting conditioning
  • Provides antistatic benefits in hair care applications

Known concerns

  • Mild skin and eye irritation possible at high concentrations
  • Not recommended for leave-on above typical use concentrations
