Diethyl Succinate
An ester of succinic acid, used as a solvent and for scent.
What it does
It’s succinic acid joined to ethanol. The EU lists it as a solvent, a skin softener, a fragrance ingredient and a plasticizer, which keeps films flexible.
The evidence, graded
expert consensusUS safety reviewers (2012) assessed dicarboxylic acids and their salts and esters; their index lists diisopropyl adipate, diisopropyl sebacate and malonic acid under that report, and their conclusion names diethyl succinate. They say most of the acids adjust pH or add scent, and some esters condition or soften skin, or work as solvents. Data were missing for some, so they extended data on similar ones to the whole group, and judged the report’s ingredients safe as used.Fiume 2012 · International Journal of Toxicology ↗
