    摘要: 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.

    摘要: 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.

    摘要: 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.
