Definitions

• Still another object of this invention is the provision of a detergent in precursor form which substantially alleviates the above mentioned problems of the detergent trade.
• Another object of this invention is to provide a deter gent composition that is safe to substantially allsurfaces in high concentrations for short periods of time if applied directly to a surface moistened with water.
• a solution comprising water, a nonionic detergent of the class consisting of ethoxylated alkyl phenols, preferably an ethoxylated nonyl or octyl phenol containing from 9 to mols of ethylene oxide repeating units; a resin of the alkylene maleic anhydride type such as a methyl vinyl ether maleic anhydride copolymer or ethylene maleic anhydride copolymer, preferably the former; and a small amount of an alkaline agent such as an alkali hydroxide, preferaby sodium hydroxide is composed and briefly heated at elevated temperature, about F, for a short time period, about 30 minutes, during which interaction between the nonionic and the polymer occurs resulting in partial esterification of the carboxyl groups of the copolymer.
• a nonionic detergent of the class consisting of ethoxylated alkyl phenols, preferably an ethoxylated nonyl or octyl phenol containing from
• the mixture is allowed to cool; then cast upon a suitable surface and allowed to dry either spontaneously or by supplying hot air to the exposed surface.
• suitable surface examples include glass, plastic treated surfaces such as polyethylene, polyvinyl chloride and Teflon.
• the film prepared as just described can be of any desired thickness. It can be readily stripped from the receiving surface and cut to any desired dimension. For example, a film having a thickness of about 18 mils and an area of about 18 square inches when dissolved in one gallon of water provides an effective detergent solution.
• a pliant, non-tacky, self-sustaining film having a water content of about 2% by weight and formed by casting upon a receptive surface to permit evaporation of water from a solution consisting of about 83 parts of water, 10 parts of an ethoxylated nonyl phenol having from 9l() mols. of ethylene oxide, 4 parts of methyl vinyl ether maleic anhydride copolymer, and about 3 parts of a 20% w/w sodium hydroxide solution; said solution being heated to about 195F. for about thirty minutes, then cooled to the point of clarity at which the pH is about 4.0-4.4.
