Abstract:
The aqueous hard surface cleaner composition, consisting essentially of:about 0.02 to 0.2% by weight of a surface tension reducing agent selected from the group consisting of linear aliphatic pyrrolidone surfactants, acetylenic diols, fluorinated surfactants, low HLB silicones, and mixtures thereof;about 0.01 to 0.1% by weight of a superwetting agent selected from the group consisting of di- or tri-siloxane glycol ethers, amine glycol ethers of the formula H.sub.2 N--(CH.sub.2).sub.x --(OCH.sub.2 CH.sub.2).sub.y --OH, where x=2-4 and y=4-10, low volatile organic content acetylenic diols, di- or tri-siloxane glycerol polymers with a glycerol based hydrophilic head, amine glycerol polymers with a glycerol based hydrophilic head, and mixtures thereof;about 0.75 to 3% by weight of an organic agent which is a mixture of dipropylene glycol methyl ether, N-methyl pyrrolidone and propylene glycol n-propyl ether in equal proportion;water, wherein the pH of the aqueous composition is in a range of about 4 to 9;optionally, about 0.5 to 1.0% by weight of an emulsifier;optionally, a chelating agent;optionally, an organic acid and/or an organic amine to adjust the pH of the aqueous composition to said pH range; andoptionally, a biocide.
