Description

Cyclohexanone (CAS 108-94-1), also known commercially as Sextone and Pimelin Ketone, is a cyclic ketone solvent used across industrial and specialty chemical applications. With FEMA 3909 status, it also holds a recognized position in flavor and fragrance work. Its solvency strength and compatibility with resins and polymers make it a practical choice.

In coatings and lacquer formulations, it dissolves nitrocellulose, vinyl resins, and synthetic rubbers where weaker solvents fall short. It is a key component for high-performance systems. Personal care and cosmetic formulators use it as a carrier solvent in nail products and specialty adhesive systems requiring controlled evaporation. It ensures consistent application and finish.

In flavor and fragrance compounding, its FEMA-approved status permits use as a flavoring agent where a mild, earthy ketone note is required. It serves as a versatile process solvent. It also functions as a process solvent in polymer and resin manufacturing, particularly where high solvency power and controlled boiling point are procurement priorities for the facility.

The product is supplied as a clear liquid in drum, IBC, and bulk tanker quantities. Technical grade is the standard commercial offering, with purity levels typically at 99% or higher. Food-grade and flavor-compliant specifications are available for applications requiring regulatory alignment. All batches are tested to ensure they meet the necessary industrial requirements.
