What is Cyclohexanone?
Cyclohexanone (CAS 108-94-1), also known commercially as Sextone and Pimelin Ketone, is a cyclic ketone solvent. FEMA 3909.
Where is Cyclohexanone used?
- Coatings and lacquers: dissolves nitrocellulose, vinyl resins and synthetic rubbers where weaker solvents fall short
- Personal care and cosmetics: carrier solvent in nail products and specialty adhesive systems requiring controlled evaporation
- Flavor and fragrance compounding: flavoring agent where a mild, earthy ketone note is required
- Polymer and resin manufacturing: process solvent where high solvency power and controlled boiling point are procurement priorities
Commercial specifications
- Technical grade standard, purity typically 99% or higher
- Clear liquid in drum, IBC and bulk tanker quantities
