  • Liquid and semisolid lubricant compositions, methods of making, and uses thereof
    Patent number: 11136525
    Abstract: Various liquid and semisolid lubricant compositions are provided, in particular lubricant compositions containing oil from the seeds of the Brassicaceae Orychophragmus violaceus, preferably those that have been esterified with one or more fatty acids such as palmitoleic acid, oleic acid, linoleic acid, lauric acid, palmitic acid, stearic acid, or a combination thereof. In various aspects, lubricant compositions are provided that include a petroleum or a synthetic base oil and about 40% or less by weight of a liquid lubricant composition containing oil from the seeds of the Brassicaceae Orychophragmus violaceus, preferably those that have been esterified with one or more fatty acids. In various aspects, semisolid lubricant composition are provided containing an emulsion of (i) a thickener and (ii) an oil from the seeds of the Brassicaceae Orychophragmus violaceus, preferably those that have been esterified with one or more fatty acids.

  • LUBRICANT COMPOSITIONS HAVING ENHANCED ESTOLIDE CONTENT, METHODS OF MAKING, AND USES THEREOF
    Publication number: 20210115352
    Abstract: Various liquid and semisolid lubricant compositions are provided, in particular lubricant compositions are provided which have been chemically modified to increase a concentration of triacylglyceride estolide content. The estolides can be produced via esterification with one or more fatty acids such as palmitoleic acid, oleic acid, linoleic acid, lauric acid, palmitic acid, stearic acid, or a combination thereof. Both liquid and semisolid lubricant compositions are provided.

  • Method of enhancing quality factors in cotton
    Patent number: 8097768
    Abstract: Preferred embodiments of this invention relate to a method for increasing fiber yield in a cotton plant by regenerating a whole cotton plant from a plant cell that has been transformed with a dominant negative allele for an endoplasmic reticulum located gene. The expression of this gene results in suppression of oil and protein biosynthesis in the developing seed and increased production of fiber in the plant.
