Fine

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

A low-ethoxylated sorbitan oleate (sorbitan monooleate with ~3 EO units) used as an emulsifier and surfactant in cosmetic formulations, closely related to Polysorbate 81.

PEG-3 Sorbitan Oleate is a sorbitol-derived ethoxylated ester of oleic acid (analogous to Polysorbate 81 with only 3 EO units rather than the typical 20). The low EO degree gives it somewhat more lipophilic character. EU Regulation 1223/2009 does not specifically restrict PEG-sorbitan oleates; they are permitted as surfactants and emulsifiers. Standard residual solvent testing (including 1,4-dioxane) is recommended per SCCS Notes of Guidance.

Skin benefits

  • Provides emulsification for oil-phase ingredients
  • Aids in creating smooth, stable cosmetic emulsions

Known concerns

  • Low EO degree slightly increases concern for skin interaction vs. higher-EO polysorbates
  • 1,4-dioxane residual monitoring required
