Safety score · 0–100

Fine

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

A short-chain PEG ether built on a branched propylheptyl alcohol — used as a mild surfactant and emulsion stabiliser. Generally well tolerated when purified, but published safety data is thin so it sits in the "fine with caveats" band.
