Fine

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

A heavily ethoxylated Polysorbate 40 variant (80 mol EO) used as a skin-conditioning surfactant, particularly in products requiring high water solubility.

PEG-80 Sorbitan Palmitate is a highly ethoxylated polysorbate emulsifier derived from palmitic acid. It is not restricted under EU cosmetics law and is considered safe in routine cosmetic use. The high EO number (80) means a substantial polyethylene glycol fraction is present; while PEGs themselves are well studied and safe, the associated manufacturing impurity profile (including 1,4-dioxane) is regulated. No specific EU concentration limits apply to this ingredient.

Skin benefits

  • Strong surfactant and emulsifying properties
  • Improves solubility of lipophilic ingredients

Known concerns

  • Potential trace 1,4-dioxane from ethoxylation (EU-regulated impurity)
  • Elevated PEG content from high EO degree
