Jojoba liquid wax

Jojoba liquid wax : it is obtained by pressing the seeds, in particular the cotyledons, of Simmondsia chinensis, family Buxacee; large shrub with a long-lasting round shape, capable of exceeding 200 years of age.

The composition of the liquid wax, improperly called oil due to its fluid consistency, is characterized by the union of long chain unsaturated fatty acids (mainly C40 and C42) with monoethylene alcohols different from glycerol. The yellowish coloration of jojoba oil is determined by the presence of flavonoids and terpenoid-derived compounds, known as tocopherols and tocotrienols, which together constitute vitamin E. These constituents are the basis of the particular chemical properties of jojoba wax, consisting of greater fluidity, stability, flammability and oxidation resistance (thanks to the presence of tocopherols). The health-giving expressions of this wax, well known in the cosmetic and dermatological sector, are evident in a marked emollient property, which allows greater penetration, prompt epidermal absorption and high film-forming activity. Moreover, the antioxidant and protective properties make it particularly suitable as a functional ingredient in sunscreen products, due to its UV stability. Jojoba wax, which is also associated with a proven antibacterial activity, is also used in products for the scalp and hair, according to the ancient popular custom.
