Safety score · 0–100

Moderate

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

A PEG-20 modified rapeseed oil emulsifier, helps blend oil and water phases together in cosmetic formulations.

Bis-(Methyl Epoxidized Rapeseedate) PEG-20 falls between PEG-12 and PEG-32 in terms of PEG chain length. The generic CAS (2767294-14-2) covers all these related compounds. The safety profile reflects the balance between the shorter PEG chain (less penetration risk than PEG-32) and the epoxidized rapeseedate source material, which may contain residual epichlorohydrin or other processing chemicals.

Skin benefits

  • Emulsifier in cosmetic formulations
  • Skin conditioning from emollient rapeseedate moiety

Known concerns

  • Epoxidized oil allergen/sensitizer potential
