Jojoba is native to a triangle of the Sonoran Desert whose corners are roughly Los Angeles (California), Phoenix (Arizona), and the southern tip of Baja California (Mexico). This area encompasses some of the earth’s most inhospitable land: in some places rainfall is as sparse as 3 inches (8 cm) a year, and temperatures soar as high as 130°F (54°C). Few crops could survive this blistering environment, but among the rocks, gravel, and sand, jojoba endures.
The severity of its native habitat endows the plant with a rugged, robust nature. Some of the most northerly jojoba plants get snowed on in winter. Some westerly ones grow in sand dunes, often exposed to ocean spray, which few other species can survive. The easterly ones are in dry deserts where some years rain refuses to come at all............
No other plant is known to produce liquids of this type (In recent years, loose claims that meadowfoam produces this kind of oil have been reported. However, it produces a glyceride oil much like rapeseed oil; to convert it into a jojobalike oil takes a series of chemical transformations). Jojoba apparently evolved unique enzymes and biosynthetic pathways to produce and metabolize (during seed germination) its unusual lipid. The chemical structure of the oil does not vary appreciably with plant type, growing location, soil type, rainfall, or altitude. For instance, plants throughout California and Arizona produce oil of virtually the same composition.
Most seeds contain between 45 and 55 percent oil, and average about 50 percent – more than twice the amount found in soybeans and somewhat more than in most oilseed crops. Extracting the oil is a straightforward process done with standard mechanical presses used for separating oil from peanuts, cottonseeds, soybeans, and other oilseeds. The presses extract about 76 percent of the oil in the first run and an additional 6-10 percent in a second pressing........
The jojoba industry is fast moving into the production stage, and it will have to resolve these uncertainties soon. In a year or two, yields will surpass the needs of the present cosmetics markets, and jojoba producers will have to move from providing a high-priced speciality product to providing a lower-priced industrial commodity.
Because of this transition, any recently quoted prices for jojoba oil ($40-$55 per gallon in mid-1985, the equivalent of $10-$14 per liter) are misleading for the long term.........
Until the early 1970s, sperm-whale oil was a common ingredient in high-quality lubricants. It was used notably in vehicle differentials and transmissions, in hydraulic fluids that need a low coefficient of friction, and in cutting and drawing oils. The high-pressure lubricants used worldwide – for example, those in most automobile transmissions – commonly contained 5-25 percent sperm oil. In some of these, unmodified sperm oil was used, but more often it was sulfurized; sometimes it was epoxidized, chlorinated, or phosphorylated before being added to the lubricant base stock.
The enactment of legislation to preserve the sperm whale banned all these uses. However, jojoba oil’s composition and physical properties are close enough to those of sperm oil to ensure its suitability as a substitute. In principle, it, too, could end up in most of the vehicle transmissions used around the world. Its oiliness and surface-wetting properties are particularly promising for extreme-pressure/extreme-temperature gear oils and greases. Its wetting properties mean reduced wear and its nondrying characteristics prevent gumming and tackiness.
