  • Patent number: 9815780
    Abstract: Quaternary ammonium, betaine, or sulfobetaine compositions derived from fatty amines, wherein the fatty amine is made by reducing the amide reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives and a secondary amine, are disclosed. Quaternary ammonium, betaine, or sulfobetaine compositions derived from fatty amidoamines, wherein the amidoamine is made by reacting of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives and an aminoalkyl-substituted tertiary amine, are also disclosed. The quaternized compositions are advantageously sulfonated or sulfitated. In one aspect, the ester derivative of the C10-C17 monounsaturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. In other aspects, the ester derivative is a modified triglyceride N made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin.

  • Patent number: 9598359
    Abstract: Sulfonate compositions are disclosed. The compositions include alkanesulfonates, alkenesulfonates, sultones, and hydroxy-substituted alkanesulfonates. The sulfonates comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a sulfonating or sulfitating agent. In one aspect, the sulfonate composition is a sulfo-estolide made by reacting a metathesis-derived C10-C17 monounsaturated acid or octadecene-1,18-dioic acid with a sulfonating agent, optionally in the presence of a saturated fatty acid. The sulfonates are valuable for a wide variety of end uses, including cleaners, fabric treatment, hair conditioning, personal care (liquid cleansing products, conditioning bars, oral care products), paint additives, antimicrobial compositions, agricultural uses, and oil field applications.

In other aspects, the ester derivative is a modified triglyceride made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin.

  • Patent number: 8536112
    Abstract: Liquid cleaning compositions are described that comprise sulfo-estolide (SE) salts, particular sodium, lithium or ammonium salts of sulfo-estolides, and alkyl ester sulfonates. The liquid cleaning compositions are clear, stable and substantially free of precipitates due to the use of sodium, lithium or ammonium salts of sulfo-estolide rather than a potassium sulfo-estolide salt in the composition. The liquid cleaning compositions also have a total combined amount of saturated C16 and C18 fatty acids of less than about 5% by weight to prevent the formation of precipitates in the composition.
