Limonene can be extracted from orange peels by juicing the orange peel and then distilling away the other components of orange oil. The juicing extraction process creates food grade d-Limonene, which can then be converted into technical grade by steam extraction of the orange peels.
d-Limonene is most often used in both household and industrial cleaning products, because it is a safe chemical that can be diluted with water or used as a powerful solvent for use in cleaning wipes, sprays and liquids. d-Limonene is also used in paint solid production or as a secondary cooling fluid. It also gives products an orange scent.
