Improved compositions which 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 comprising surfactant, wherein said surfactant 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 quaternized polydimethylsiloxane, preferably one which comprises a cation of the general formula:[R1R2R3N-Z-[Si(CH3)2-O]nSi(CH3)2-Z-NR4R5R6]2+ wherein R1, R2, R3, R4, R5 and R6 are independently alkyl or hydrogen, Z is -CH2-CHOH-CH2O-(CH2)3- and n is 1-200. |
