The new crop oil from jojoba (Simmondsia chinensis) is a skin-softener similar to sperm whale oil. In an effort to find new uses of this oil, we have converted jojoba liquid wax into two new products in mild chemical processes. Tetrahydroxyjojoba wax (THJF) is a colorless, stable, low-melting solid and jojoba ferulate, an ultra violet (UV) absorbing species by esterification of the tetrahydroxy...

beta-Ketoacyl-coenzyme A (CoA) synthase (KCS) catalyzes the condensation of malonyl-CoA with long-chain acyl-CoA. This reaction is the initial step of the microsomal fatty acyl-CoA elongation pathway responsible for formation of very long chain fatty acids (VLCFAs, or fatty acids with chain lengths > 18 carbons). Manipulation of this pathway is significant for agriculture, because it is the bas...

Oils of a significant value both as fuels as well as for cosmetic applications can be extracted from the fruits of the jojoba plant. After extracting the oil, the remains of the fruit can still be further utilized as a solid fuel in furnaces or feedstock to animals. In the present work, the solid waste jojoba remains have been processed chemically to extract more biodiesel oil. The physical and...

The oxidative stability indices (OSI) of several vegetable oils were determined at 11O°e. Meadowfoam oil, Limnanthes alba, was found to be the most stable oil with an OSI time of 67.3 h for refined oil and 246.9 h for crude oil. Other oils with good oxidative stabilities were refined high oleic sunflower and crude jojoba oil (Simmondsia chinensis) with OSI times of 49.8 and 34.5 h respectively....

Wax esters are esters of long-chain fatty acids and long-chain fatty alcohols which are of considerable commercial importance and are produced on a scale of 3 million tons per year. The oil from the jojoba plant (Simmondsia chinensis) is the main biological source of wax esters. Although it has a multitude of potential applications, the use of jojoba oil is restricted, due to its high price. In...

Jojoba liquid wax is a mixture of esters of long-chain fatty acids and fatty alcohols mainly C38:2-C46:2. The oil exhibits excellent emolliency on the skin and, therefore, is a component in many personal care cosmetic formulations. The virgin oil is a component of the seed of the jojoba (Simmondsia chinensis) plant which occurs naturally in the Sonora Desert in the United States and northwester...

This reaction is the initial step of the microsomal fatty acyl-COA elongation pathway responsible for formation of very long chain fatty acids (VLCFAs, or fatty acids with chain lengths >18 carbons). Manipulation of this pathway is significant for agriculture, because i t is the basis ...

Jojoba [Simmondsia chinensis, Simmondsiaceae, (Link) Schnieder], a native of deserts of the American Southwest, is unusual and perhaps unique amongst higher plants in that its seed storage lipids are liquid waxes rather than triglycerides. These waxes are esters of long chain (mostly; C20, C22, and C24), monounsaturated, fatty acids and alcohols. The waxes are produced in developing embryos dur...

The present work comprises the formulation and evaluation delivery system of transdermal drug with a view of developing and preparing a losartan potassium releasing system utilizing natural oils as permeation enhancers for transdermal applications. Matrix systems were prepared by using polyvinyl pyrrolidine and ethyl cellulose (EC) polymers by incorporating dibutyl phthalate as plasticizer and ...

the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...
