It contains antioxidants and other nutrients. Jojoba oil is rich in the skin-nourishing antioxidant Vitamin E (known for keeping age-related changes at bay) plus Vitamins A and D. It also contains the minerals chromium, copper, and zinc, plus Omega 6 and 9 fatty acids.
What is the molecular weight of jojoba oil?
325.38 g/mol
The average molecular weight (MW) of JME was 325.38 g/mol, which was calculated from the FA profile. The main FA found in SME was linoleic acid (C18:2, 52.4%), with oleic (C18:1, 22.1%) and palmitic (C16:0, 11.4%) acids also noticed in considerable amounts.

Is jojoba oil a lipid?
Jojoba oil is a fatty acid-containing wax ester and is different from common vegetable oils, rich in triglycerides.
What is the pH of jojoba oil?
about 4.5-5
All plant oils are acidic, jojoba oil, the base of my cleansers has a pH of about 4.5-5 – ideal for restoring and maintaining the correct pH.
How is jojoba oil made?
Jojoba oil is obtained from the plant S. chinensis, a drought-resistant shrub found mainly in the Sonoran desert where it has very high economic value. Jojoba oil is extracted from the seeds by cold pressing. A crystalline, hard wax can be prepared by hydrogenation of the oil [29].
What is the density of jojoba oil?

What is argan oil made up of?
Argan oil is made from the kernels that grow on the argan trees native to Morocco. It’s most frequently sold as pure oil, which can be directly applied topically (directly to the skin) or ingested in order to provide several health benefits. It comes in supplement capsule form to be taken by mouth.
Does jojoba oil oxidize?
Jojoba oil is liquid at room temperature because of its unsaturated fatty acids. It does not oxidize or become rancid and does not break down under high temperatures and pressures. The stability shown by jojoba oil makes it especially useful for cosmetic applications.
Does jojoba oil have amino acids?
data shown in Tables 3 and 4 show that the essential amino acids of jojoba corresponded to 45.74% of the total amino acid content, and that the protein isolate showed good levels of most of the individual essential amino acids as compared with the amounts recommended by FAO/WHO/ UNU (1989).
What is the scientific name for jojoba oil?
Unlike vegetable oils and animal fats, jojoba (Simmondsia chinensis) oil is not a triglyceride but a mixture of long chain esters (97–98%) of fatty acids and fatty alcohols, and therefore is more properly referred to as a wax; however, jojoba oil-wax is the term in general use (Canoira et al., 2006).
Is jojoba oil polar or nonpolar?
Some examples of polar oils include the following: Avocado oil. Jojoba wax / Jojoba oil. Flaxseed oil.
What kind of oil is jojoba oil made of?
Jojoba oil. The terms “jojoba oil” and “jojoba wax” are often used interchangeably because the wax visually appears to be a mobile oil, but as a wax it is composed almost entirely (~97%) of mono-esters of long-chain fatty acids and alcohols, accompanied by only a tiny fraction of triglyceride esters.
What makes up 50% of jojoba seed by weight?
The oil makes up approximately 50% of the jojoba seed by weight, and simmondsin is one of its principal component. This oil is different from other common plant oils, since it is composed almost completely (97%) of wax esters of monounsaturated, straight-chain acids and alcohols with high molecular weights (carbon chain lengths from 36 to 46).
What can jojoba seed oil be used for?
Therefore, jojoba seed oil is used as a carrier substance for oxidation sensitive substances such as vitamin A. In addition, Jojoba liquid wax is useful in the stabilization of penicillin products. In fact, it has been shown to be the finest liquid wax for this purpose.
Why is jojoba oil considered to be shelf stable?
Jojoba oil is relatively shelf-stable when compared with other vegetable oils mainly because it contains few triglycerides, unlike most other vegetable oils such as grape seed oil and coconut oil. It has an oxidative stability index of approximately 60, which means that it is more shelf-stable than safflower oil, canola oil,…
