Composition and method for increasing water and oil repellency of textiles and carpet

The present invention relates to a method for adjusting the pH of water in swimming pools or hot tubs or in drinking water by adding to the water an effective amount of a salt of urea and hydrochloric acid.

Method for adjusting the pH of swimming pool, hot tub, or drinking water

A method for the adjustment of pH in textile processing or other solutions, including recreational waters, that includes the use of urea sulfate or its equivalent.

Lowering the pH with an acid/base salt as a pH adjusting agent

A method to remove the build-up of water-insoluble metal salts on surfaces, and a method to lower the solids content of industrial liquids that contain water-insoluble metal salts using urea hydrochloride or its equivalent. Also disclosed is a method to use urea hydrochloride or an equivalent strong acid/weak base salt as acid replacements for a variety of purposes.

Method for adjusting pH in textile processing solutions with urea

Permanently soil resistant polymeric compositions that have fluorochemical dispersed throughout the polymer are prepared by melt extrusion of the fluorochemical with the desired polymer. Preferred polymers for extrusion with the fluorochemical are polyester, polypropylene, polyethylene, and polyamide.
