Description
A colorless solvent with a lemon-like odor that is occurs naturally from the oils of lemon, orange, caraway, dill, and bergamot. Limonene is used as a wetting and dispersing agent in liquid soaps, inks, perfumes, paints, varnishes, floor waxes, and furniture polishes. It is also used as a solvent for alkyd resins, Rosin, waxes, and Rubber compounds.
