Patent number: 5855621Abstract: The transfer of a textile dye from a dyed fabric to another fabric during washing or rinsing is inhibited by adding an enzyme exhibiting peroxidase activity or an enzyme exhibiting a suitable oxidase activity to the wash liquor in which said fabrics are washed and/or rinsed. Peroxidase is produced extracellularly by some strains of Bacillus pumilus. The novel peroxidase preparation from B. pumilus is a microperoxidase, i.e. it contains hemopeptide as an active component. The preparation has improved stability at high temperature, at high pH and at high concentrations of hydrogen peroxide. It can be produced without undesired catalase activity.Type: GrantFiled: May 23, 1995Date of Patent: January 5, 1999Assignee: Novo Nordisk A/SInventors: Ture Damhus, Ole Kirk, Gitte Pedersen, Manuel Garcia Venegas

Patent number: 5688757Abstract: Certain sugar derivatives have bleach-activating effect both on "hydrophilic" stains (e.g. tea or red wine) and on "hydrophobic" stains (e.g. grass or tomato sauce). The compounds in question are derivatives of pentoses or hexoses, having a long-chain acyl group and one or more short-chain acyl or aroyl groups attached through ester bonds. Optionally, a short-chain alkyl group is attached through a glycosidic bond. These compounds are non-toxic and biodegradable, and can conveniently be prepared by methods known in the art.Type: GrantFiled: January 7, 1994Date of Patent: November 18, 1997Assignees: Novo Nordisk A/S The Procter & Gamble Co., Novo AlleInventors: Ture Damhus, Ole Kirk, Frederick Edward Hardy

Patent number: 5534435Abstract: The invention relates to a process for converting peroxycarboxylic acids to carboxylic acids, the process comprising treating a peroxycarboxylic acid of the general formula I:R--CO--OOH (I)wherein R is a linear or branched alkyl group, an aryl group or an aryl-alkyl group each of which may optionally be substituted with one or more hydroxy, halogen, alkoxy, amino, alkylamino, sulfo, sulfoxy, sulfono, amido, carboxy, percarboxy or nitro groups, with an enzyme catalyst to form the corresponding carboxylic acid of the general formula II:R--CO--OH (II)wherein R has the meaning indicated above.Type: GrantFiled: February 8, 1995Date of Patent: July 9, 1996Assignee: Novo Nordisk A/SInventors: Sven E.

Patent number: 5431849Abstract: Esters of monosaccharides and their lower alkyl glycosides are effective both as suffactants and as bleach activators (peracid precursors). The compounds are non-toxic and biodegradable. They act as nonionic suffactants and are effective in soil removal from textiles, e.g. of fatty soiling. In the presence of a hydrogen peroxide source, the sugar derivatives are perhydrolyzed during the washing process to form long-chain peracid. This enhances the bleaching effect, especially on hydrophobic stains.Type: GrantFiled: June 19, 1991Date of Patent: July 11, 1995Assignee: Novo Nordisk A/SInventors: Ture Damhus, Ole Kirk, Frederick E.
