Hard surface liquid cleaning composition with anti-soiling polymer |
(57) An aqueous solution of an anti-static cationic quaternized polymer is used to deposit
the polymer as a soil releasing agent on hard surface, e.g. bathroom porcelain, tiles,
etc. in order to provide easier cleaning of the treated surface during subsequent
cleaning operation. A preferred polymer is based on recurring units of beta-(trialkyl
ammonium) alkyl methacrylate with a molecular weight of from about 5,000 to 50,000
or more.
