Publication number: 20080234166Abstract: Composition and method for bleaching are presented. The composition includes a reactor and an oxidizing agent. The reactor includes a core that contains an oxidizer reactant and generates dioxirane, percarboxylic acid, chlorine dioxide, hydroxyl radicals, and/or N-halo-amine when contacted by a main solvent. A reactor wall surrounds the core and controls diffusion of the main solvent to the core through the pores. The reactor wall has a substantially lower solubility in the main solvent than the oxidizer reactant and the generated product such that the reactor wall remains substantially intact until generation of the product is substantially complete. The oxidizing agent is in contact with the main solvent. The oxidizing agent, which may be a hypohalite donor, chlorine dioxide donor, halo-amine donor, percarboxylic acid donor, hydroxyl radical donor, persulfate(s), or a hydrogen peroxide donor, has an order of selectivity that is different from the product generated in the reactor.Type: ApplicationFiled: September 16, 2005Publication date: September 25, 2008Inventors: Perry L. Martin, Roy W. Martin

Patent number: 7375072Abstract: A builder-containing laundry detergent or cleaning composition is comprised of: (1) alkali metal percarbonate; (2) a water-soluble builder block which comprised of: a) from 5% by weight to 35% by weight of citric acid, an alkali metal citrate, an alkali metal carbonate, and/or an alkali metal hydrogen carbonate, b) up to 10% by weight of alkali metal silicate having a modulus in the range from 1.8 to 2.5, c) up to 2% by weight of phosphonic acid and/or alkali metal phosphate, d) up to 50% by weight of alkali metal phosphate, and e) up to 10% by weight of polymeric polycarboxylate, wherein at least two of components b), c), d) and e) are present in amounts greater than 0% by weight, and (3) a soil release-capable alkyl or hydroxyalkyl cellulose derivative. The soil release-capable action of cellulose derivatives is particularly marked when they are used in laundry detergents or cleaning compositions which comprise alkali metal percarbonates and contain only water-soluble builders.Type: GrantFiled: August 10, 2005Date of Patent: May 20, 2008Assignee: Henkel Kommanditgesellschaft auf AktienInventor: Josef Penninger
