About

A quaternary ammonium surfactant with both PEG and quaternary functionalities, used for its conditioning and antimicrobial properties in rinse-off products.

PEG/PPG-1/25 Diethylmonium Chloride is a cationic surfactant combining PEG and quaternary ammonium chemistries. The PEG chain reduces the cationic charge density, making it milder than traditional quats. The diethylmonium structure is not specifically restricted in EU CosIng. Quaternary ammonium compounds with short PEG chains are generally considered safe in rinse-off formulations, though they are typically avoided in leave-on products due to potential eye irritation.

Skin benefits

  • Antimicrobial and conditioning properties
  • Static control in hair care formulations
  • Provides softening effects in skin cleansers

Known concerns

  • Mild eye irritation potential from quaternary ammonium structure
  • Avoid contact with eyes in rinse-off formulations
  • Generally not recommended for leave-on products
