About
ISOBUTYL METHYLBUTYRATE is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.
Isobutyl methylbutyrate is a branched-chain ester functioning as a fragrance ingredient with characteristic fruity, apple, and banana notes. It is not listed on EU Annexes II or III and carries no GHS hazard statements, consistent with its favourable toxicological profile as a simple aliphatic ester.
