These are vegetable fats that are extracted by crushing seeds (rosehip
seed and grapeseed), nuts (sweet almond, coconut and macadamia), fruits
(avocado and jojoba) and leaves (aloe vera). Essential oils will not
dissolve in water. Carriers are used to dissolve as well as dilute
essential oils to a concentration of 1-3% before applying to the skin.
Carrier oils are vulnerable to heat, light and air and must be protected
to avoid rancidity.
