Dihydroisophorone

Dihydroisophorone (CAS 873-94-9, EC 212-855-9) is a cyclic ketone solvent also known as 3,3,5-trimethylcyclohexanone. It carries no assigned E-code and is not classified as a food additive. It is commercially available as a racemic mixture under the designation (±)-dihydroisophorone.

In personal care formulations, dihydroisophorone functions as a solvent and carrier, dissolving active ingredients and fragrance components that resist water-based systems. It is also used as a flavoring agent in certain applications, where its mild, woody-minty odour profile contributes directly to the sensory character of the finished product. Its low volatility relative to lighter ketones supports controlled evaporation in leave-on formulations.

Dihydroisophorone is supplied as a technical-grade liquid and falls under REACH registration requirements for EU market access. It is classified under HS code 29142200 for customs purposes. Packaging formats typically follow standard industrial conventions; buyers should confirm grade specifications and documentation with the supplier prior to order.
