![]() To make things even worse, lavender oil seems to be cytotoxic from concentrations as low as 0.25% (concentration up to 0.125% were ok). The two main components are linalyl acetate (about 50%) and linalool (about 35%) and both autoxidise on exposure to the air forming strong contact allergens. Now, let us look at the cons: similar to a bunch of other essential oils, the main components of lavender oil are potentially irritating fragrant components. (The main components of the flower essential oil are linalyl acetate and linalool while it is 1,8-Cineole in the essential oil of the leaves.) We have found a study confirming this but it was the essential oil of the leaves and not the much more commonly used flowers and the two differ in their main chemical compounds very much. ![]() Lavender oil is also often claimed to have anti-inflammatory properties. It also has some local pain relieving and muscle relaxing magical powers. 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 oil being a wax ester is uniquely excellent at doing that.Īnother pro is that lavender oil has some nice antimicrobial and antibacterial properties. Third, jojoba oil 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 hand, it absorbs into the skin through pores and hair follicles then diffuses into the intercellular spaces of the outer layer of the skin to make it soft and supple. has this not fully proven theory that thanks to this, jojoba might be able to "trick" the skin into thinking it has already produced enough sebum, so it might have "skin balancing" properties for oily skin. Second, jojoba oil is the most similar to human sebum (both being wax esters), and the two are completely miscible. If you have some pure jojoba oil at home, you should be fine using it for years. (Many plant oils tend to go off pretty quickly). Even if you heat it to 370 C (698 F) for 96 hours, it does not budge. So being a wax ester results in a couple of unique properties: First, jojoba oil is extremely stable. ![]() 25-30% of human sebum is also wax esters to give us people environmental protection. Wax esters are on the outer surface of several plant leaves to give them environmental protection. Chemically, a wax ester is a fatty acid + a fatty alcohol, one long molecule. Mother Nature also created wax esters but for a totally different purpose. ![]() Mother Nature created triglycerides to be easily hydrolyzed (be broken down to a glycerin + 3 fatty acid molecules) and oxidized (the fatty acid is broken down into small parts) - this happens basically when we eat fats or oils and our body generates energy from it. The fatty acids attached to the glycerin vary and thus we have many kinds of oils, but they are all triglycerides. ![]() So what the heck is a wax ester and why is that important anyway? Well, to understand what a wax ester is, you first have to know that oils are chemically triglycerides: one glycerin + three fatty acids attached to it. ![]()
