Bleaching (detergent) compositions are disclosed comprising a peroxide bleaching agent and a novel cationic peroxyacid bleach precursor having at least one of the following groups (A) and (B) :
wherein R₁ and R₂ are each individually H, or a substituent group containing at least one carbon atom, provided that R₁ and R₂ are not both H.
The novel bleach precursor of the cationic nitrile type shows no tendency to deliquesce under normal atmospheric conditions.

The present invention relates to a method for producing an organic composition containing a functional component selected from the group consisting of a thermoplastic polymer, an enzyme, a setting agent, a paraffin, an oil, a colorant and a hair or skin care substance. The method includes providing an n-nonyl ether, a functional component which is able to react with an n-nonyl alcohol component, and, if appropriate, at least one further additive substance; and mixing the n-nonyl ether, the functional component and the at least one further additive substance. The invention further relates to a method for producing and using a molded article, a method for producing an item to be packaged, the use of at least one n-nonyl ether, a method for producing and/or cleaning the surfaces of boreholes, drilling devises or drill cuttings, and also to methods for producing an oil or a gas.

A bleaching composition for laundry fabrics is provided, comprising:
hydrogen peroxide or a source of hydrogen peroxide;
a bleach catalyst comprising a ligand which forms a complex with a transition metal, the complex catalysing bleaching of stains in the presence of peroxygen bleach or a peroxy-based or -generating bleach system; and
a dye transfer inhibiting agent.
The bleaching composition provides effective bleaching performance on fabric stains without unacceptable transfer of dyes between fabrics.

The invention relates to a liquid bleaching composition for catalytically bleaching substrates, especially laundry fabrics, with atmospheric oxygen or air. A liquid bleaching composition is provided comprising an organic substance which forms a complex with a transition metal, the complex catalysing bleaching of a substrate by atmospheric oxygen, and a liquid carrier or solvent, wherein the composition is substantially devoid of peroxygen bleach or a peroxy-based or -generating bleach system. Also provided is a method of bleaching a substrate comprising applying the liquid bleaching composition to the substrate. Also provided is a method of treating a textile by contacting the textile with the liquid bleaching composition, whereby the complex catalyses bleaching of the textile by atmospheric oxygen after the treatment.

A bleaching composition for laundry fabrics is provided, comprising:
hydrogen peroxide or a source of hydrogen peroxide;
a bleach catalyst comprising a ligand which forms a complex with a transition metal, the complex catalyzing bleaching of stains in the presence of peroxygen bleach or a peroxy-based or -generating bleach system; and
less than 4.0% by weight of a peroxyacid bleach precursor.
The bleaching composition provides effective bleaching performance on fabric stains without causing unacceptable dye damage or dye fading of the fabrics after repeated washes.
