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

A stable dry solid composition for souring laundered textile materials and imparting softness thereto consisting essentially of

• I. 5-50% by weight of a fatty amide softening agent for textile materials corresponding to the structural formula ##STR8## wherein R is selected from the group consisting of monovalent alkyl radicals and sulfonated monovalent alkyl radicals containing about 8-22 carbon atoms, R.sub.2 is selected from the group consisting of hydrogen and ##STR9## wherein R is as defined above, R.sub.3 is selected from the group consisting of hydrogen and monovalent alkyl radicals containing 1-2 carbon atoms, and m is 2-6;
• and
• Ii. 95-90% 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 2-20 carbon atoms and having a primary ionization constant between about 10.sup.-1 and 10.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.
