Lotions, salves, creams, body oils, massage oils, bath oils, lip balms and other moisturizing skin care products are made using carrier oils. Some carrier oils are odorless but most have a faintly sweet, nutty aroma. Carrier oils do not evaporate but can go rancid over time. A longer shelf life can be had by adding vitamin E.
The olive oil we are going to use is a cold pressed, virgin oil. It you are going to heat your plant materials in the oil you do not need to purchase the cold pressed oil.
