<p>A process for isomerization of natural jojoba oil, a wax-type ester is described. It is based on contacting jojoba oil, essentially all cis-configuration with an acidic bentonite-type clay at temperatures in the range 150-350.degree.C. The resulting isomerates, predominately of trans-configuration have melting points in the range 25.degree. to about 44.degree.C. Also included are useful isomorphous compositions of the trans-isomerates of jojoba oil with hydrogenated jojoba oil. These compositions are useful as candle waxes, non-stick cooking sprays, cosmetic vehicles, carriers for solid "detergent" soaps, leather treatments, hand modifiers for textiles including both woven and non-woven fabrics. The compositions consist of liquid, solid and semi-solid solutions of the components thereof. They are formed by heating to melting of the components and then cooling the solutions.</p> |
