Safety score · 0–100

Good

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A higher-ethoxylation version of PEG glyceryl tristearate, functioning as a solubilizer and emulsifier for oils and fragrances in water-based products.

This 20-mol EO adduct of glyceryl tristearate acts as a lipophilic emulsifier and fragrance solubilizer. The higher degree of ethoxylation increases its water solubility compared to lower-EO variants. Similar high-molecular-weight PEG esters have received CIR approval when properly purified. Under EU Regulation (EC) No 1223/2009, these substances are regulated as standard cosmetic raw materials with no specific annex restrictions, though manufacturer purity specs must be met.

Skin benefits

  • Excellent fragrance solubilization in clear aqueous products
  • Provides stable emulsions at low use levels

Known concerns

  • Residual 1,4-dioxane must be controlled during manufacturing
  • May contribute to emulsification issues in formulations with very high oil phases
