The present invention provides a process for removal of excess dye from newly manufactured printed or dyed fabric or yarn, comprising treatment with a rinse liquor comprising at least one enzyme selected from the group consisting of enzymes exhibiting peroxidase activity or laccase activity, an oxidation agent, and at least one mediator comprising N-hydroxyacetanilide.

Process for removal of excess dye from printed or dyed fabric or yarn

The present invention provides a process for removal of excess dye from newly manufactured printed or dyed fabric or yarn, comprising treatment with a rinse liquor comprising at least one enzyme selected from the group consisting of enzymes exhibiting peroxidase activity or laccase activity, an oxidation agent, and at least one mediator selected from the group consisting of aliphatic, cyclo-aliphatic, heterocyclic or aromatic compounds containing the moiety >N&mdash;OH, in particular 1-hydroxybenzotriazole.

The present invention provides a process for removal of excess dye from newly manufactured printed or dyed fabric or yarn, comprising treatment with a rinse liquor comprising at least one enzyme selected from the group consisting of enzymes exhibiting peroxidase activity or laccase activity, an oxidation agent, and at least one mediator selected from the group consisting of aliphatic, cyclo-aliphatic, heterocyclic or aromatic compounds containing the moiety &gt;N--OH, in particular 1-hydroxybenzotriazole.

The present invention relates to novel variants of Coprinus cinereus peroxidase showing excellent hydrogen peroxide stability.

Peroxidase variants

Enhancers such as acetosyringone

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.

Dye transfer inhibition

Detergent compositions

Dye transfer inhibition and novel peroxidase

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.

Sugar derivatives containing both long and short chain acyl groups as

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:
