Good

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

A light, liquid emollient made from PEG-2 and isononanoic acid — gives products a smooth, non-greasy glide and helps water-and-oil phases mix together.

PEG-2 diisononanoate is a diester of polyethylene glycol-2 (average 2 ethylene oxide units) with isononanoic acid (a branched C9 fatty acid). The short PEG chain gives this ingredient both hydrophilic and lipophilic character, making it an effective emulsifying or co-emulsifying agent. It is liquid at room temperature and contributes a dry, velvety skin feel. No EU restrictions apply to this ingredient in its standard cosmetic use.
