Mother Nature besides created wax esters but for a wholly different purpose. Chemically, a wax ester is a fatty acid + a fatty alcohol, one long molecule. wax esters are on the outer surface of several plant leaves to give them environmental protection. 25-30 % of human sebum is besides wax esters to give us people environmental protection.
so being a wax ester results in a couple of unique properties : First, jojoba petroleum is extremely stable. Like brainsick stable. even if you heat it to 370 C ( 698 F ) for 96 hours, it does not budge. ( many establish oils tend to go off pretty quickly ). If you have some pure jojoba vegetable oil at home, you should be fine using it for years.
second, jojoba oil is the most similar to human sebum ( both being wax esters ), and the two are wholly miscible. Acne.org has this not amply raise theory that thanks to this, jojoba might be able to “ trick ” the skin into thinking it has already produced adequate sebum, so it might have “skin balancing” properties for greasy skin .
Third, jojoba petroleum moisturizes the skin through a unique dual action: on the one hand, it mixes with sebum and forms a thin, non-greasy, semi-occlusive layer ; on the other pass, it absorbs into the skin through pores and haircloth follicles then diffuses into the intercellular spaces of the extinct level of the hide to make it soft and supple .
On balance, the point is this : in contrast to real plant oils, wax esters were designed by Mother Nature to stay on the surface and form a protective, moisturizing barrier and jojoba anoint being a wax ester is uniquely excellent at doing that .
