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, a fatty amphoteric compound, or a fatty amide as described hereinafter 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, a fatty amphoteric compound or a fatty amide as described hereinafter 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.
