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

Claim 1

A stable homogeneous liquid composition for souring laundered textile materials and imparting softness thereto comprising: I. about 0.5-25% 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 ##EQU1## 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 about 1-22 carbon atoms, n is about 1-6, X is an anion selected from the group consisting of halide, sulfate, phosphate, alkyl sulfates having about 1-3 carbon atoms in the alkyl group and alkyl phosphates 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; B. quaternized fatty amines corresponding to the following structural formula ##EQU2## wherein R, R', X and Y are as defined in (A) above; C. An aqueous emulsion of partially oxidized emulsifiable polyethylene having a molecular weight of about 1000-10,000, and D. fatty amphoteric compounds corresponding to the structural formula ##EQU3## wherein R, R' and n are as defined in (A) above, the said amphoteric compounds having non-acidic isoelectric ranges; Ii. about 7.5-75% by weight of an acidic souring agent for laundered textile materials, the souring agent being a water soluble organic carboxylic acid containing about 2-10 carbon atoms and having a primary ionization constant between 10.sup. -1 and 10.sup. -5 , and Iii. about 0-92% by weight of water; the said ingredients I and II being present in amounts whereby laundered textile materials are effectively softened and simultaneously soured upon treatment with the said liquid composition, and the said ingredients I, II and III being present in amounts whereby a stable homogeneous liquid composition is produced.
