Abstract

See full text

Aqueous hard surface cleaners and concentrates are disclosed. In one aspect, the cleaners comprise water, a monounsaturated C8-C14 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 C8-C14 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.
