About

A polyoxypropylene polyoxyethylene copolymer functioning as an emulsifier and solubilizer in cosmetic formulations. The PPG and PEG chain lengths influence its safety profile, with skin irritation possible at high concentrations.

PPG-1-Deceth-5 is a polyalkylene glycol ether emulsifier with both polypropylene glycol (PPG) and polyethylene glycol (PEG) segments. It is not listed in EU Annex II (banned substances) or Annex III (restricted substances) of the Cosmetics Regulation, indicating permitted cosmetic use. The ingredient serves as an emulsifier and solubilizer, and the mixed PPG/PEG structure may reduce the skin barrier disruption associated with purely ethoxylated compounds. However, as with many emulsifiers, it may contribute to skin dryness or irritation in sensitive individuals at high concentrations.

Skin benefits

  • Emulsifying agent for oil-in-water formulations
  • Solubilizer for fragrance and oil components
  • Improves product texture and consistency

Known concerns

  • May cause skin dryness or irritation in sensitive individuals at high concentrations
  • Ethoxylated component may contain trace residual ethylene oxide
  • PPG component may raise concerns for comedogenic potential
