The invention meets the needs above by providing a surfactant system, mixture or blend that can be used as a part of a soaking composition. The surfactant system is capable of forming emulsions with, and thus removing, oily and greasy stains. In a preferred embodiment the surfactant compositions of the invention can remove non-trans fat and fatty acid stains. The invention involves foaming soaking compositions that have some or part of the anionic surfactant present in the same replaced with an extended chain anionic surfactant.

Liquid detergent composition that includes a surfactant system and encapsulates. Methods for making and using such detergents.

Liquid detergent compositions having a surfactant system and encapsulates, where the surfactant system includes anionic alkoxylated alkyl sulphate surfactant. Methods of making and using such detergents.

Liquid compositions include: a) one or more anionic surfactants and b) one or more nonionic surfactants,
wherein they comprise the surfactants of components a) and b) in a total concentration of >25% by weight, based on the total weight of the liquid composition, and are free from alkanolamines and salts thereof. Upon combination with bleaches, the liquid compositions exhibit a significantly higher bleaching efficacy than comparable alkanolamine-containing compositions.

Aqueous hard surface cleaners and concentrates are disclosed. In one aspect, the cleaners comprise water, a monounsaturated C.sub.8-C.sub.14 fatty N,N-dialkylamide, and at least one anionic, cationic, nonionic, or amphoteric surfactant. The cleaners have a pH within the range of 6.0 to 9.0. Dilutable hard surface cleaner concentrates comprising the monounsaturated N,N-dialkylamide and a surfactant are also disclosed. Also included are aqueous hard surface cleaners which comprise a monounsaturated N,N-dialkylamide, and which by measure of ASTM D4488-95 A5 soil, provide superior percent cleaning at a pH less than 10 than they do at pH 10 and higher. Surprisingly, when a monounsaturated C.sub.8-C.sub.14 fatty N,N-dialkylamide is included in the aqueous hard surface cleaner or concentrate, rapid and thorough cleaning performance can be achieved even at relatively neutral pH. Consequently, the hard surface cleaners are effective on greasy soils, including baked-on soils, despite their low alkalinity.
