Bitter orange oil

Bitter orange oil (CAS 68916-04-1), also known as sour orange oil, is a cold-pressed or steam-distilled essential oil derived from the peel of Citrus aurantium. It delivers a sharp, distinctive citrus character used as a flavoring agent and fragrance ingredient across food, cosmetic, and pharmaceutical manufacturing.

In food and beverage production, it functions as a natural flavoring in liqueurs, confectionery, marmalades, and soft drink concentrates where a bitter citrus profile is required. Fragrance formulators incorporate it into fine perfumery and eau de cologne bases.

It is also used in functional fragrance blends for personal care products including soaps, lotions, and shampoos. Pharmaceutical and nutraceutical manufacturers use it as a flavoring excipient to mask bitterness in oral dosage forms and as a carrier in topical preparations.

In home care formulations, it contributes both fragrance character and solvent functionality to surface cleaners and air fresheners. Bitter orange oil is supplied as a mobile amber-to-yellow liquid, available in standard packaging ranging from small drums to bulk quantities.

It is offered in food-grade and cosmetic-grade specifications, with FEMA 2345 recognition supporting its use in flavoring applications. Buyers should confirm origin, extraction method, and compliance with relevant regional flavor and fragrance regulations when sourcing.
