TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition preferably comprises (wt.%) volatile ketone (10-90) and volatile ester (10-90).Preferred Components: The hydrocarbon surfactant is an anionic surfactant e.g. sodium, magnesium or ammonium dioctyl sulfosuccinate, dodecyl sulfate or laureth sulfate and/or their acids, or a zwitterionic surfactant e.g. cocoamidopropyl betaine. The salt that is organic is sodium benzoate, magnesium benzoate, sodium acetate and/or magnesium acetate. The alcohol is ethanol and/or isopropanol. The neutralizing agent is 2-amino-2-methyl-1-propanol and/or dimethyl stearamine. The liquefied propellant gas is dimethyl ether; propane and butane; or a mixture of dimethyl ether, propane and butane. The volatile ester is methyl acetate, ethyl acetate, propyl acetate and/or butyl acetate. The volatile ketone is acetone.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The polymer, which has a molecular weight of 10-1000 kilo Daltons, is ethyl acrylate, methyl methacrylate and methacrylic acid copolymer; ethyl acrylate, t-butyl acrylate and methacrylic acid terpolymer; octyl acrylamide, acrylates and butylaminoethyl methacrylate copolymer; methacrylic acid, n-butyl acrylate and methyl methacrylate copolymer; methacrylic acid, n-butyl acrylate and ethyl methacrylate copolymer; butyl acrylate, methyl methacrylate, hydroxyethyl methacrylate and methacrylic acid copolymer; vinyl acetate, crotonates and vinyl neodecanoate copolymer; a butyl ester of vinyl methyl ether and maleic anhydride copolymer; an ethyl ester of vinyl methyl ether and maleic anhydride copolymer; a polymer which consists of polystyrene sulfonate monomers; a polymer which consists of 1-vinyl-2-pyrrolidone; vinyl acetate and vinylpyrrolidone copolymer; vinylcaprolactam homopolymer; a quaternary ammonium polymer formed by the reaction of diethyl sulfate and a copolymer of vinyl pyrrolidone and dimethyl aminoethylmethacrylate; and/or modified polyurethanes and unmodified polyurethanes. The silicone based surfactant is dimethicone copolyol and/or cyclomethicone.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The salt may also be inorganic, such as sodium chloride and/or magnesium chloride. The neutralizing agent may also be sodium hydroxide and/or potassium hydroxide. EXAMPLE - Both sodium benzoate and magnesium acetate, as tested using dynamic surface tension measurement, brought the surface tension difference of the 55% VOC test solution closer to that of the commercial product.
