Limonene is a chiral molecule, and biological sources produce one enantiomer: the principal industrial source, citrus fruit, contains (+)-limonene (d-limonene), which is the -enantiomer. [ 1 ] (+)-Limonene is obtained commercially from citrus fruits through two primary methods: centrifugal separation or steam distillation .
Consists of 90% d-Limonene. Used as a fragrance, in cleaning products and in flavoring foods. [8] Orcein – color (red) Orchil – color (red) Oregano (Origanum vulgare, O. heracleoticum, and other species) – Oregano oil – contains thymol and carvacrol; Orris root – Orthophenyl phenol – preservative; Oxidised polyethylene wax – humectant
The oil consists of approximately 90% D-limonene, a solvent used in household chemicals such as wood conditioners for furniture and—along with other citrus oils—detergents and hand cleansers. It is an efficient cleaning agent with a pleasant smell, promoted for being environmentally friendly and therefore preferable to petrochemicals.
