D-Limonene 94% - Food Grade

Product Overview

D-Limonene 94% - Food Grade is a high-purity terpene solvent extracted from citrus fruit peels. Chemically known as 1-Methyl-4-(1-methylethenyl)-cyclohexene, this colorless liquid offers superior solvency power compared to mineral spirits and other petroleum-based cleaners. With a minimum assay of 94%, it meets USP and Food Grade purity standards, making it suitable for use in facilities where high-quality inputs are required for equipment cleaning and process formulations.

Also known as Orange Oil or Citrus Terpene (CAS 5989-27-5), D-Limonene acts as a versatile industrial degreaser and cleaner. Its chemical structure allows it to effectively dissolve oils, greases, tars, and adhesives. As a biodegradable alternative to chlorinated solvents, it is widely used in parts washing, concrete cleaning, and general industrial maintenance. The specific gravity of approximately 0.845 ensures easy phase separation in aqueous systems.
