Abstract
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 mount such that the pH of the composition is less than about 4.5; and the surfactant is a compound of formula (I): ##STR1## wherein R.sup.1, R.sup.2, and R.sup.3 are independently (C.sub.1 -C.sub.6)alkyl wherein any alkyl group can be substituted with one or more (C.sub.1 -C.sub.6)alkoxy or hydroxy; R.sup.4 is EQU --[R.sup.5 --O].sub.q --H or EQU --[R.sup.6 --O].sub.q --[R.sup.7 --O].sub.r --H wherein R.sup.5 and R.sup.6 are independently (C.sub.1 -C.sub.6)alkylene, wherein any alkylene group can be substituted with one or more (C.sub.1 -C.sub.6)alkoxy or hydroxy; R.sup.7 is (C.sub.1 -C.sub.6)alkylene wherein the alkylene group can be substituted with one or more (C.sub.1 -C.sub.6)alkoxy or hydroxy; q has an average value between about 1 and abo…
