Carrier Oil

Carrier oil, also known as base oil or vegetable oil, is used to dilute essential oils and absolutes before they are applied to the skin in massage and aromatherapy. They are so named because theycarry the essential oil onto the skin. Carrier oils do not contain a concentrated aroma, unlike essential oils, though some, have a mild distinctive smell. Neither do they evaporate like essential oils, which are more volatile. Cold-pressing and maceration are the two main methods of producing carrier oils. Mineral oil should not be used as it is not absorbed by the skin. All carrier oils should be kept cool, and away from strong light, to retard rancidification. Rancid oils should be avoided. Refrigerating oils helps preserve their freshness but some oils should not be refirgerated . Very cold oils may appear cloudy, but regain their clear state on returning to room temperature.
