A powerfully sulfurous thioester with a pungent, catty top note that opens into ripe tropical-fruit and blackcurrant-bud facets. Extremely diffusive and persistent — used at trace levels it lends realistic passionfruit, guava and cassis effects; overdosed it reads as sweaty, urinous and mercaptan-like.AI · claude-opus-4-7

Colorless liquid
Poorly soluble in water, miscible with alcohol.
The odor varies according to origin and to the quality of the Thioglycolic acid used in the manufacture of the ester. Poorer grades yield esters of Hydrogen-sulfide-type odor.
This ester has little more than academic interest, but it may be formed in small quantities in cosmetic preparations when Thioglycolic acid and Ethylene glycol are used at the same time.
Produced by esterification of Ethylene glycol with Thioglycolic acid.
