Abstract

Liquid and solid compositions are provided for souring and imparting softness to freshly laundered textile materials. When in the form of a stable homogeneous liquid, the composition may contain a quaternized fatty amide, a quaternized fatty amine, an aqueous emulsion of partially oxidized polyethylene or a fatty amphoteric compound as a softening agent, a water soluble organic acid containing about 1-20 carbon atoms and having a primary ionization constant between 10.sup..sup.-1 and 10.sup..sup.-5 as the souring agent, and water. When in the form of a stable dry solid, the composition may contain a quaternized fatty amide, a quaternized fatty amine or a fatty amphoteric compound as the softening agent, and a dry solid water soluble organic acid containing 2-20 carbon atoms and having a primary ionization constant between 10.sup..sup.-1 and 10.sup..sup.-5 as the souring agent. Stable homogeneous stock solutions are also prepared from the novel liquid or solid compositions of the invention.

Dependent claims

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..sup.-1 and 10.sup..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.

Ii. about 95-50% by weight of an acidic souring agent for laundered textile materials, the souring agent being a dry solid water soluble organic carboxylic acid containing about 2-10 carbon atoms and having a primary ionization constant between 10.sup..sup.-1 and 10.sup..sup.-5,
the said ingredients I and II being present in amounts whereby laundered textile materials are effectively softened and simultaneously soured upon treatment with an aqueous solution for souring textile materials containing the said dry solid composition, and
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.
