Cleaning composition comprising saturated dialkyl cationic surfactants

The specification discloses improved compositions which both clean a surface and are believed to deposit thereupon a layer of cationic surfactant which assists the release of soil subsequently deposited upon the said surface. These comprise a surfactant mixture, wherein said surfactant mixture itself comprises: a) at least 65 % wt on total surfactant of nonionic surfactant; b) less than 1 % wt on total surfactant of anionic surfactant; and c) 0.1-35 % wt on total surfactant of a cationic surfactant which is a substantially ethylenically saturated dialkyl quaternary ammonium compound.
