About

PEG-30 glyceryl isostearate — a mild non-ionic emulsifier and solubiliser, popular in cleansing oils and balms. Well-tolerated at cosmetic levels; the usual PEG-class 1,4-dioxane purity caveat is the main concern.

Skin benefits

  • Mild non-ionic emulsifier for oil-in-water systems
  • Frequently used in cleansing oils and balms
  • Good skin tolerance
  • Helps solubilise fragrance and oils

Known concerns

  • PEG-based — possible 1,4-dioxane and ethylene-oxide trace residues if not purified
  • Generally mild but can cause irritation on damaged skin
  • No significant concerns at cosmetic concentrations of purified material
