  • Publication number: 20130225409
    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 sulfated. In one aspect, the ester derivative of the C10-C17 monoun-saturated acid or octadecene-1,18-dioic acid is a lower alkyl ester. 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.

  • Publication number: 20130225470
    Abstract: Fatty amide compositions and their derivatives are disclosed. The fatty amides comprise a reaction product of a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives with a primary or secondary amine. Derivatives made by reducing, quaternizing, sulfonating, alkoxylating, sulfating, and sulfitating the fatty amide are also included. The amine reactant can be diethylenetriamine or (2-aminoethyl)ethanolamine, which provide imidazoline amides or N esters, respectively. 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 made by self-metathesis of a natural oil or an unsaturated triglyceride made by cross-metathesis of a natural oil with an olefin. The compositions are valuable for cleaners, fabric treatment, hair conditioning, personal care, antimicrobial compositions, agricultural uses, and oil field applications.

  • Publication number: 20130217608
    Abstract: Laundry detergents useful for cold-water cleaning and boosted bargain detergents are disclosed. The detergents include a surfactant composition derived from a metathesis-derived C10-C17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives. For fatty alkyl ester sulfonate-containing detergents, the composition is selected from C10 betaines, C12 or C16 amidoamines, C12 ethanolamine amides, C16 amidoamine sulfonates, C18 diamidoamine dioxides, quaternized C18 diamidoamine betaines, sulfonated C18 low-EO fatty ester alkoxylates, C18 amidoamine carboxylates, and amidoamine oxides and sulfobetaines derived from cross-metathesis of palm or soybean oil. The bargain detergents include a performance booster selected from C12 low-EO fatty ester alkoxylate sulfonates, C18 amidoamine oxide esters, C18 amidoamine oxide carboxylates, and amidoamine sulfobetaines made from self metathesized palm or soybean oil.
