Description
Diisobutyl ketone (CAS 108-83-8) is a ketone solvent also known commercially as Valerone and by the FEMA designation 3537. It carries no E-code classification. It is registered under REACH (EC 203-620-1) and traded under HS code 29141990.
In food and flavour applications, diisobutyl ketone functions as a flavorant at trace concentrations, contributing fruity and cheesy top notes to finished formulations. In personal care and cosmetics, it acts as a carrier solvent, dissolving fragrance compounds and resin-based film formers due to its moderate polarity and controlled evaporation rate.
Diisobutyl ketone is available in technical and flavour-grade forms, with flavour-grade material conforming to FCC specifications. It is supplied in standard drum and IBC formats and is fully compliant with REACH registration requirements for supply within the European Economic Area.
