About

A higher-ethoxylation PEG stearate — a gentler emulsifier than its low-EO cousins. More water-soluble, less penetrating, and well-tolerated. Standard PEG dioxane-purity caveat applies but is well-controlled.

Skin benefits

  • Stable emulsions even in challenging formulas
  • Lower penetration potential
  • Compatible with sensitive skin
  • Helps solubilize oils

Known concerns

  • Trace 1,4-dioxane risk
  • Synthetic-derived
