Lime peel oil is a pale yellow liquid produced from the rind of the key lime (Citrus × aurantiifolia). Key lime is a hybrid species descended from a type of wild citrus (Citrus micrantha) and citron (Citrus medica). It is considered native to Southeast Asia and cultivated in many tropical and subtropical regions around the world. Trees grow to around 5 meters tall, with sharp thorny branches bearing small white flowers and round fruit. The fruit yellows as it ripens, and is frequently harvested for use in cuisines, being particularly prized amongst limes for its tangy flavour. The juice is a main ingredient in the famous American dessert Key Lime Pie. The fresh peel, which is typically a waste product of the juice industry, can be used to produce lime essential oil by method of cold compression, steam distillation or hydrodistillation.

Lime oil is used in perfumery, cosmetics and personal care products for its fresh citrus notes in the creation of fragrances. It is also used in foods such as pickles, jams, marmalades, sorbets and sauces for its potent lime flavour.
