Good
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A water-soluble nonionic surfactant and emulsifier derived from oleic acid with 20 ethylene oxide units, valued for its mildness and broad formulation compatibility.
PEG-20 Dioleate carries a 20-unit ethylene oxide chain giving it strong hydrophilicity and minimal skin penetration potential. It appears in EU CosIng without restriction under Regulation 1223/2009 and is widely regarded as safe in cosmetic applications. SCCS Notes of Guidance require monitoring of 1,4-dioxane at ppm levels in line with good manufacturing practice.
Skin benefits
- Mild surfactant ideal for facial cleansers and sensitive-skin products
- Excellent emulsifying efficiency for clear gel and lotion systems
Known concerns
- 1,4-dioxane trace levels must be monitored
- Extremely low sensitisation or irritation risk in final products
