All about Jojoba oil: benefits, properties and uses of the best known liquid wax in cosmetics.
What about Jojoba oil? I will tell you a secret: it is not a real vegetable oil, but a liquid vegetable wax, Jojoba wax!
The vegetable waxes are contained in the most different parts of the plants and the greatest quantity of vegetable waxes is produced by tropical plants or located in arid areas (where they are used to reduce the evaporation of humidity). Vegetable waxes:
- they are soluble in many organic solvents (ether, toluene …) but they are less soluble than real fats;
- they do not go rancid and are less easily hydrolysable than fats;
- due to the high molecular weight of their fatty acids, their saponification number is lower than that of fats. They are also characterized by a very high% unsaponifiable (sterols, higher saturated aliphatic alcohols, hydrocarbons, ..).
Among the most famous solid vegetable waxes there are: candelina wax, carnauba wax, Japanese wax, rice wax, palm wax, sugar cane wax, while among the liquid waxes Jojoba wax (or improperly but commonly called “jojoba oil “).
Jojoba oil: where it comes from
Jojoba wax is a liquid wax that is obtained from the seeds of Simmondsia californica*, a shrub that grows wild in the desert areas of California, Mexico and Arizona, an oil is extracted that differs markedly from the chemical point of view, from all the others vegetable oils.
A curiosity*: the name jojoba was originated from the “O’odham” population (correct name of the North American natives otherwise called Pima), who live in the Sonoran desert in the Southwest of the United States and Mexico, who treat sunburn with the ointment taken from oilseeds. Despite its scientific name (Simmondsia chinensis), jojoba has no relation to China. This incorrect name was due to a transcription error! the botanist Johann Link originally named the species as Buxus chinensis, after misinterpreting the words “Calif.” as “China” in the collection of Thomas Nuttall. The renaming was attempted as Simmondsia californica, but according to the rules of priority in the nomination must be privileged the specific name assigned first, and therefore the term “chinensis” remained.
Jojoba oil: characteristics
Jojoba wax (or “jojoba oil“) is golden yellow and if “of quality” should be pressed cold and filtered without the use of solvents. It has a melting point at 8 ° C, and should solidify below that temperature; if it does not, it means that it has been refined or mixed with cheaper oils.
Unlike vegetable oils, rich in triglycerides, jojoba is a wax rich in esters: more precisely, it is composed of 93% unsaturated fluid esters and for this reason it is very stable and has an excellent duration. The major component of jojoba wax is erucil 11-cis eicosinato (which makes up 43%). It also contains myristic acid and a lot of vitamin E. In cosmetics it is exploited, Jojoba wax, both the double unsaturation of esters and the excellent lubricating, protective and softening power.
