ABSTRACT

With the production phaseout of chloro¯uorocarbons (CFCs) and other ozone-depleting chemicals and increased awareness of workplace safety, many di¥erent cleaning solvents have been introduced. d-Limonene, a naturally occurring substance extracted from citrus rind during the juicing process, has shown great e¥ectiveness in the cleaning market and is experiencing a growing acceptance as the solvent of choice in a number of di¥erent applications. d-Limonene is a non-water-soluble solvent. It can be used straight or blended with an emulsi©cation system to produce a water dilutable/rinsable product. It is capable of e¥ectively removing organic dirt loads ranging from light cutting oils and lubricants to heavy greases, such as cosmoline.
