D'Limonene is obtained as a product of the citrus . It is the major component of the oil extracted from the rinds of citrus fruits. D'Limonene is lighter than water, and is usually colorless This product has a boiling range of 310-352 degrees Fahrenheit. It has a flash point of 119 degrees Fahrenheit and is considered a combustible liquid. It is not soluble in water. Depending on the composition, d-limonene can dissolve in solvents and surfactants.
As a straight solvent, d-limonene can replace many types of products such as fluorinated and chlorinated organic solvents, acetone, MEK (methyl ethyl ketone), mineral spirits, glycol ethers, and toluene. Since it is not water soluble, it can be used in typical water separation units. Straight d-limonene can be used in spray systems, as a wipe cleaner, in a dip bath and is a direct substitute for most other organic solvents.
Adhesive Remover, Asbestos shingle remover, Bathroom cleaner, Car wash, Carpet stain cleaner, Concrete cleaner (used in warehouse floor scrubbers or for cleaning oils and greases off concrete pads and parking structures), Cosmetic applications, Electronics cleaning, engine degreaser (automotive, aircraft, and aerospace industries), Floor cleaner, Fragrance additive, Graffiti remover, Grease trap maintainer, Hand cleaner, Heat transfer medium, Industrial odor control applications, Kitchen cleaner, Laundry pre-spotter, Lift station and sewage treatment applications, Marine vessel cleaner, Metal cleaner (industrial), Parts cleaner, Printing press cleaner, Recycling applications, Tar/asphalt remover, Tile remover, Wheel cleaner, Window cleaner. d'Limonene is also a possible candidate for a variety of medical applications including cancer and Aids research, and has been been noted to have insecticidal properties.
As a water dilutable and rinsable solution, d'Limonene must first be combined with a surfactant. These products are mostly used in household and institutional settings in place of caustic and other water-based cleaners. Both pre-diluted solutions of d'Limonene/surfactant or concentrated solutions which need to be diluted before use can be made. The use concentrations of d-limonene are usually 5-15%. Usually these solutions are used as wipe cleaners or as a spray. It can also be used in industrial settings where a water rinse for parts washing is desired to remove any residue which may remain.
Limonene is a clear, colourless liquid at room temperature with an extremely strong smell of Oranges. Limonene is a chiral molecule.

Safety & Precaution :
Solvent-resistant gloves should be worn when working with d-limonene. The best gloves to use are Nitrile, although Viton and polyethylene film gloves will work. d'Limonene has been classified as a slight skin irritant, because it can remove naturally occurring oils from the skin. This has not been shown to cause lasting damage.
Used straight, d-limonene can cause a certain amount of swelling of polymers, so any plastic materials must be chosen carefully. This includes equipment seals made of rubber, such as Buna-N, EPDM (ethylene-propylene diene terpolymer) or Neoprene. It is compatible with Viton. It can delaminate carpet backing. d'Limonene is biodegradable, but due to its low flash point, it must be treated as hazardous waste for disposal.
