Abstract:
A liquid composition of matter, suitable as such, after dilution with water, or both as such and after dilution with water, for aiding in the removal of soils from soiled metal workpiece surfaces by mass finishing, said liquid composition comprising water and:(A) a concentration of a component selected from the group consisting of:(A.1) nonionic surfactant molecules that contain a moiety with the chemical formula --(C.sub.m H.sub.(2m-z) X.sub.z O).sub.v --, wherein m has the value 2, 3, or 4; z represents an integer with a value from 0 to 2m; X represents a halogen atom, and if z has a value of more than 1, may represent the same or a different halogen atom for each X; and v represents a positive integer; and(A.2) anionic, amphoteric, and both anionic and amphoteric alkali stable surfactants;(B) a concentration of a component selected from the group consisting of molecules, exclusive of molecules that are part of component (A), that include a moiety corresponding to general chemical formula I: ##STR2##wherein R represents a monovalent aliphatic moiety with the chemical formula --C.sub.n H.sub.(2n+1-y) F.sub.y, wherein n is an integer from 6 to 22, and y is an integer from C to (2n+1); and(C) one or more alkali metal silicates.
