Abstract
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: PA1 a) at least 65% wt on total surfactant of nonionic surfactant, PA1 b) less than 1% wt on total surfactant of anionic surfactant, and, PA1 c) 0.1-35% wt on total surfactant of a quaternized polydimethylsiloxane, preferably one which comprises a cation of the general formula: R.sub.1 R.sub.2 R.sub.3 N--Z--Si(CH.sub.3).sub.2 --O!.sub.n Si(CH.sub.3).sub.2 --Z--NR.sub.4 R.sub.5 R.sub.6 !.sup.2+ PA1 wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are independently alkyl or hydrogen, Z is --CH.sub.2 --CHOH--CH.sub.2 O--(CH.sub.2).sub.3 -- and n is 1-200.
