<p>The present invention provides for a composition suitable for removing proteinaceous material comprising water, an emulsifier, a chelating agent, one or more mineral acids, and a surfactant; wherein: the emulsifier is a polyether nonionic emulsifier or an amine oxide; the chelating agent is an alkylaminophosphonic acid, a hydroxyalkylphosphonic acid, or an alkylphosphonic acid carboxylic acid; the one or more mineral acids are present in an amount such that the pH of the composition is less than about 4.5; and the surfactant is a compound of formula (I): wherein R1, R2, and R3 are independently (C1-C6)alkyl wherein any alkyl group can be substituted with one or more (C1-C6)alkoxy or hydroxy; R4 is (a) or (b) wherein R5 and R6 are independently (C1-C6)alkylene, wherein any alkylene group can be substituted with one or more (C1-C6)alkoxy or hydroxy; R7 is (C1-C6)alkylene wherein the alkylene group can be substituted with one or more (C1-C6)alkoxy or hydroxy; q has an average value between about 1 and about 100; r has an average value between about 1 and about 100; and X is halo, RCOO-, PO42- or SO42- wherein R is (C1-C6)alkyl.</p> |
