Jojoba oil comes from the beans of a shrub like plant, mild odor, it is favored as a carrier oil due to its molecular stability. The absorption properties of this oil are similar to our skins own sebum making it great for the skin and scalp treatments. Jojoba oil may become cloudy and solidify as the temperature drops. This is a normal process that occurs from the hardening of the fats and waxes, and it will become stable at or around room temperature. Because Jojoba is not an oil but rather a wax, its shelf life and stability is considerably higher then most oils and rancidity is very rarely a concern.
