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 C 10 -C 17 monounsaturated acid, octadecene-1,18-dioic acid, or their ester derivatives. For fatty alkyl ester sulfonate-containing detergents, the composition is selected from C 10 betaines, C 12 or C 16 amidoamines, C 12 ethanolamine amides, C 16 amidoamine sulfonates, C 18 diamidoamine dioxides, quaternized C 18 diamidoamine betaines, sulfonated C 18 low-EO fatty ester alkoxylates, C 18 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 C 12 low-EO fatty ester alkoxylate sulfonates, C 18 amidoamine oxide esters, C 18 amidoamine oxide carboxylates, and amidoamine sulfobetaines made from self metathesized palm or soybean oil.

First claim

We claim:

1. A boosted bargain laundry detergent, comprising 1 to 70 wt. % of an anionic surfactant, 5 to 70 wt. % of a nonionic surfactant, and 0.1 to 5 wt. % of a metathesis-based performance booster selected from the group consisting of
(a) a C 12 low-EO fatty ester alkoxylate sulfonate having the structure:

(b) a C 18 amidoamine oxide ester having the structure:

(c) a C 18 amidoamine oxide carboxylate having the structure:

and
(d) an amidoamine sulfobetaine made from self-metathesized palm or soybean oil having the structure:

2. The detergent of claim 1 wherein the metathesis-based performance booster has at least 1 mole % of trans-Δ 9 unsaturation.

3. The detergent of claim 1 further comprising water.

4. A liquid, powder, paste, granule, tablet, molded solid, water-soluble sheet, or water-soluble sachet comprising the detergent of claim 1 .
