Abstract
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) a quaternized fatty amide, an aqueous emulsion of partially oxidized polyethylene or a fatty amphoteric compound as the softening agent, (b) hydrofluorosilicic acid, ammonium silicofluoride, zinc silicofluoride, ammonium acid fluoride, potassium acid fluoride, or orthophosphoric acid as the souring agent, and (c) water. When in the form of a stable dry solid, the composition may contain (a) a quaternized fatty amide or fatty amphoteric compound as the softening agent, and (b) ammonium silicofluoride, potassium silicofluoride, sodium silicofluoride, zinc silicofluoride, ammonium acid fluoride, sodium acid fluoride or potassium acid fluoride. A method of preparing the liquid composition is provided which insures that it remains stable and homogeneous while awaiting use. Stable homogeneous aqueous stock solutions are also prepared from the liquid or solid compositions of the invention.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
153 words
A stable homogeneous liquid composition for souring laundered textile materials and imparting softness thereto consisting essentially of I. about 0.5-25% by weight of a softening agent for textile materials, the softening agent being a fatty amphoteric compound corresponding to the structural formula ##STR4## 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, and n is about 1-6, the said amphoteric compounds having non-acidic isoelectric ranges; Ii. about 3-50% by weight of an acidic souring agent for laundered textile materials selected from the group consisting of ammonium acid fluoride and potassium acid fluoride; and Iii. about 25-96.5% by weight of water; the said ingredients I, II and III being present in amounts whereby a stable homogeneous liquid composition is produced.
Claim 2
Dependent Claim
153 words
A stable homogeneous liquid composition for souring laundered textile materials and imparting softness thereto consisting essentially of I. about 0.5-25% by weight of a softening agent for textile materials, the softening agent being a fatty amphoteric compound corresponding to the structural formula ##STR4## 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, and n is about 1-6, the said amphoteric compounds having non-acidic isoelectric ranges; Ii. about 3-50% by weight of an acidic souring agent for laundered textile materials selected from the group consisting of ammonium acid fluoride and potassium acid fluoride; and Iii. about 25-96.5% by weight of water; the said ingredients I, II and III being present in amounts whereby a stable homogeneous liquid composition is produced.
