Compositions for souring and softening laundered textile materials, and stock solutions prepared therefrom

Claim 1

A stable dry solid composition for souring laundered textile material and imparting softness thereto consisting essentially of I. about 5-50% by weight of a softening agent for textile materials selected from the group consisting of (A) quaternized fatty amides corresponding to the following structural formulae ##STR3## wherein R is selected from the group consisting of monovalent alkyl radicals and sulfonated monovalent alkyl radicals containing about 8-22 carbon atoms, R' is selected from the group consisting of monovalent alkyl radicals and sulfonated monovalent alkyl radicals containing about 1-3 carbon atoms, Z is selected from the group consisting of monovalent alkyl radicals and sulfonated monovalent alkyl radicals containing 1-22 carbon atoms, n contains about 1-6 carbon atoms, X is an anion selected from the group consisting of halide, sulfate, phosphate, alkyl sulfate having about 1-3 carbon atoms in the alkyl group and alkyl phosphate having about 1-3 carbon atoms in the alkyl group, and Y is an integer having a numerical value equivalent to the valency of X, and (B) fatty amphoteric compounds corresponding to the structural formula ##STR4## wherein R, R' and n are as defined in (A) above, the said amphoteric compounds having non-acidic isoelectric ranges; and II. about 95-50% by weight of an acidic souring agent for freshly laundered textile materials selected from the group consisting of ammonium acid fluoride, sodium acid fluoride and potassium acid fluoride, the said ingredients I and II being present in amounts whereby a stable solid composition is produced for souring laundered textile materials and imparting softness thereto.
