Description

Isophorone (CAS 78-59-1 ) is a cyclic ketone solvent used across industrial coatings, specialty chemical synthesis, and flavoring applications. With FEMA 3553 designation, it is also recognized in flavor formulation under the alternate commercial name Isoforone. Its slow evaporation rate and strong solvency make it a preferred carrier in high-solids systems where controlled drying is critical. In coatings and lacquers, it dissolves nitrocellulose, epoxy, and polyurethane resins effectively. This solvent supports high-build formulations where solvent balance directly affects film quality. It functions as a reaction medium and intermediate in the synthesis of isophorone diamine and isophorone diisocyanate. These are key building blocks for polyurethane systems. In personal care manufacturing, it serves as a carrier solvent in nail lacquers and specialty cosmetic formulations requiring controlled evaporation rates for optimal application. At permitted use levels, it contributes a fruity, herbal note to flavor compositions targeting baked goods and beverages. Isophorone is supplied as a clear liquid in drum and IBC quantities for various industrial needs. Bulk tanker options are available for larger industrial volumes. Technical grade is the standard offering for coatings and synthesis applications. Food and flavor-compliant material is available to meet specific purity requirements. This material is designed to meet the necessary standards for use in regulated flavor formulations. Our supply chain ensures consistent quality and availability for both industrial and food-grade applications globally. Contact us for supply of Isophorone Request Quote
