Abstract:
A rinse aid composition for use in a dishwashing machine wherein said rinse aid composition provides improved proteinaceous soil-removing properties to soiled dishware, said composition comprising(a) 0.1% to 30% by weight of a cationic polymer containing 40-100 mole % of monomer units corresponding to formula I: ##STR6## in which R.sup.1 is hydrogen or a methyl group,R.sup.2, R.sup.3 and R.sup.4 are the same or different and represent hydrogen or a C.sub.1-8 alk(en)yl group, R.sup.8 is a linear, cyclic or branched alkylene group containing 2 to 8 carbon atoms, andX represents a monofunctional anion or the 1/m part of an m-functional anion,(b) 0.5% to 30% by weight of an aliphatic di- or tricarboxylic acid,(c) 0.5% to 30% by weight of nonionic surfactants selected from the group consisting of end-capped and OH-terminated fatty alcohol polypropylene glycol/polyethylene glycol ethers, alkyl polyglycosides, C.sub.6-22 fatty acid-N-alkyl polyhydroxyalkylamides, C.sub.6-22 fatty acid alkanolamides, C.sub.6-22 fatty acid-N-alkyl polyhydroxyalkyl amides, fatty alkyl amine oxides and mixtures thereof, and(d) 10% by weight to 98.1% by weight of water, based on the weight of said rinse aid composition; and(e) a solubilizer comprising cumene sulfonate or an alkali metal salt thereof.
