Patent number: 11713245Abstract: An article for generating chlorine dioxide includes a canister containing a chlorine-dioxide generating composition. The articles in accordance with the invention are able to generate chlorine-dioxide gas, chlorine-dioxide solution, and chlorine-dioxide solution with surfactants. The canister includes at least one porous region that places an exterior of the canister in fluidic communication with an interior of the canister. The porous region, which in some embodiments, is realized as a mesh, is characterized by a size in a range of about 20 mesh to about 325 mesh.Type: GrantFiled: December 17, 2009Date of Patent: August 1, 2023Assignee: SIPKA INC.Inventor: John Appadurai Thangaraj

Patent number: 9834443Abstract: A composition for generating chlorine dioxide comprises active ingredients, a suitable hydrophobic compound, and a suitable super absorbent compound. A suitable hydrophobic compound will, among other characteristics, repel the solvent for at least the initial 30 seconds of exposure thereto. A suitable super absorbent compound will, among other characteristics, absorb at least 75 times its weight in solvent and will not gel until the chlorine-dioxide generating reaction is substantially complete.Type: GrantFiled: September 23, 2013Date of Patent: December 5, 2017Assignee: Sipka, Inc.Inventors: John Appadurai Thangaraj, Lakkaraju Dasaradhi

Publication number: 20080067470Abstract: Some embodiments of the invention provide solid compositions that, when exposed to or otherwise placed in an aqueous solution, will release chlorine dioxide and surfactants, producing a soapy, aqueous solution containing chlorine dioxide. These solid compositions comprise an alkali chlorite salt, a solid acid source, and a surfactant. In some other embodiments, the solid compositions produce a non-soapy aqueous solution containing chlorine dioxide. These solid compositions comprise an alkali chlorite salt and a solid acid source.Type: ApplicationFiled: September 12, 2007Publication date: March 20, 2008Applicant: SIPKA INC.Inventors: John Thangaraj, Lakkaraju Dasaradhi
