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.
