Orange oil is an essential oil produced by glands inside the rind of an orange fruit. It is extracted or steam distilled as a by-product of orange juice production. It is composed of mostly (greater than 90%) d-limonene, and is therefore often used in place of pure d-limonene, which can be further extracted from the oil by distillation. Limonene is what gives citrus fruit their familiar aroma, and is therefore used in perfume and household cleaners for its fragrance. It is also an effective, environmentally friendly, and relatively safe solvent, which makes it an active ingredient of choice in many applications, such as, adhesive and stain removers, cleaners of various sorts, and strippers.
Orange oil can be used in biological pest control Green pesticides, and can kill individual and colonies of Ants and eradicate their "scent-pheromone trail" indicators to disrupt re-infestation. It is safe in areas such as kitchens.
