General-purpose cleaning compositions |
(57) A general purpose cleaning composition comprises 0.01 to 90% by weight of a nonionic
surfactant, 0.005 to 50% by weight of a cationic surfactant which has a sanitising
action, and 0.003 to 20% by weight of a non-anionic polymer which has an adsorptive
affinity to hard surfaces. The inclusion of the non-anionic polymer in general-purpose
cleaners containing a nonionic and a cationic detergent provides a significant streak
free benefit in the cleaned surfaces.
