'Fragrance oil'(s), also known as 'aroma oils', 'aromatic oils', and 'flavor oils', are blended
synthetic aroma compounds or natural
essential oils that are diluted with a carrier like
propylene glycol,
vegetable oil, or
mineral oil. Aromatic oils are used in
perfumery,
cosmetics,
flavoring of
food, and in
aromatherapy.
To some people, synthetic fragrance oils are less desirable than plant-derived essential oils as components of perfume.
