US20080067470A1 - Methods and Solid Compositions for Generating Soapy and Non-Soapy Aqueous Solutions Containing Free Chlorine Dioxide - Google Patents
Patent for Hand soap with chlorine dioxide. Co-inventor John Thangaraj. "a relatively high yield of chlorine dioxide is obtained from a solid composition that has a relatively greater amount of acid and a relatively lesser amount of alkali chlorite salt. Conversely, a relatively low yield of chlorine dioxide is obtained from a solid composition that has a relatively lesser amount of acid and a relatively greater amount of alkali chlorite salt. For example, a solid composition comprising five (5) weight percent of sodium chlorite and forty (40) weight percent of acid will generate far more chlorine dioxide than a solid composition comprising seventy (70) weight percent of sodium chlorite and twenty (20) weight percent of acid. " "Coloring agents, dyes and fragrances are also not recommended for use in the solid compositions disclosed herein because they rapidly react with chlorine dioxide"
