Orange oil is a versatile essential oil derived from the peel of oranges. This oil is popular in aromatherapy, skincare, and cleaning products due to its fresh and uplifting scent. Some of the common synonyms for the term "orange oil" include sweet orange oil, citrus aurantium dulcis oil, and neroli oil. These oils share similar characteristics and benefits, making them interchangeable in many applications. Another popular synonym is bitter orange oil, which has a sharper, more bitter scent than sweet orange oil.
