Abstract
Abstract A clear, aqueous hard surface, essentially streak free, cleaning composition, comprising (a) a surfactant selected from the group of (i) polyoxyethylene/polyoxypropylene block copolymers having a number average molecular weight of from about 3000 to 7000, a percent hydrophile content of about 10 to 60 percent (ii) an alcohol ethoxylate of the formula ##STR1## wherein R is an alkyl chain whose length is from about 8 to 15 carbon atoms, x is a number from about 4 to 15, y is a number from about 0 to 15, and z is a number from about 0 to 5, and mixtures thereof; and (b) 3 to 5 percent by weight organic solvents and water. The composition may also include a synergistic amount of a polycarboxylate copolymer comprised of a combination of copolymerized monomer units, monoethylenically unsaturated mono- and dicarboxylic acids, diolefins and alkyl vinyl ethers. The general structure of said copolymer is as follows: ##STR2## wherein X═H, Na, or similar alkaline metals; A═H, COOH, COONa or similar salts, or an alkyl group having a chain length of 6 to 20 carbon atoms and preferably 6 to 10 carbon atoms, and m and n are numbers such that the monomer ratio is in the range of about 3:1 to 1:3 and a total average molecular weight of the copolymer is from 1,000 to 70,000.
