Carrier oils also referred to as base oils or vegetable oils are used to dilute essential oils, CO2s and absolutes before applying to the skin. They carry the essential oil onto the skin. Different carrier oils offer different properties and the choice of carrier oil can depend on the therapeutic benefit being sought.Carrier oils are generally cold-pressed vegetable oils derived from the fatty portions of the plant. Unlike essential oils that evaporate and have a concentrated aroma, carrier oils do not evaporate or impart their aroma as strongly as essential oils. They can, however, go rancid. Our carrier oils are natural and unadulterated. Exceptions include buying carrier oils that have natural vitamin E added. Vitamin E acts as a natural preservative. Most oils bought in the grocery store are not cold-pressed. Instead, the oils are heated and therefore have less therapeutic benefit. Mineral oil is not used in aromatherapy because mineral oil is not a natural product. It is also said that mineral oil can prevent essential oil absorption into the skin. Cold Pressed - A method of mechanical extraction where heat is reduced and minimized throughout the batching of the raw material. This helps the oil maintain its original state, constituents, and depth. Temperatures are rigorously controlled to ensure that it does not exceed 80-90 degrees Fahrenheit. Although not a practical method of extraction for all vegetable oils on the market it is highly regarded as the extraction method of choice.
