A method for point-of-use generation of chlorine dioxide wherein the chlorine dioxide is generated quickly and at acceptable concentrations to avoid the need for subsequent dilutions and keeping the product non corrosive to the surface to be treated. A persulfate solution and a chlorite solution are mixed at a molar ratio of persulfate to chlorite of greater than 2. The chlorite solution is buffered to a pH of from 9 to 12. The persulfate solution is buffered to a pH of from 3 to 9.

An electrolytic device for the generation of hypohalous acid in aqueous solutions includes at least a single liquid chamber for receiving an aqueous solution containing halide ions therein, the single liquid chamber having an exterior wall and a solid anode contained within to provide for the oxidation of the halide ions, which, in turn, provides for the formation of hypohalous acid in aqueous solution, and a gas permeable cathode forming a portion of the exterior wall of the single liquid chamber, the cathode providing for the reduction of oxygen to provide hydroxyl ions in solution within the single liquid chamber to mix with the products generated at the anode. An embodiment of the electrolytic device including an anolyte chamber and a catholyte chamber separated by an ionomeric membrane is also described, whereby the anolyte chamber further includes an outlet including a pH control for determining and regulating the pH of the exiting anolyte effluent to between about 4 and 9. The product is suitable for disinfectant applications including as a hand sanitizer.

This invention relates to stable oil-in-water emulsions and to products based on such emulsions which contain a modified polymer which is a copolymer of a preponderant amount of an acrylic acid and a smaller amount of a long chain acrylate monomer which modified polymer renders the emulsions stable for over a year at room temperature and which imparts to the emulsions the quick breaking property whereby the emulsions break on coming in contact with an electrolyte or skin, instantaneously coalescing and releasing oil from the emulsions.

A process for the preparation of smooth oil and water emulsions of excellent texture and appearance comprising adding together emulsion-forming ingredients consisting essentially of oil, water, and surfactant; selecting as said surfactant a polyglycerol ester of a fatty acid having a fatty acid composition which is primarily palmitic and stearic acids, said ester having an average degree of polymerization in the range of about 2 to about 6, a hydroxyl number in the range of about 280-425, and a saponification number in the range of about 120-140; and intensively mixing said ingredients together at an elevated temperature; said mixing being carried out at a pH greater than about 7. In a preferred embodiment, the pH subsequent to mixing is reduced to about 5-7. 5, to produce a gelled emulsion having the texture and appearance of oil-rich emulsions, the proportions of oil and surfactant of the gelled emulsion being about 5-25% and 2. 5-10%, respectively, based on the weight of gel-forming ingredients.
