A water-soluble pouch, a process for producing a water-soluble pouch and the use of an electrostatically charged powder for coating film material are provided.

Water-soluble pouches

The present invention relates to an article comprising: (a) a liquid composition comprising: (i) enzyme; and (ii) from 0% to 10% (by weight of said liquid composition) free water, preferably 0% to 5% free water; and (iii) carboxylic acid comprising 5 carbon atoms or less, and 1 or 2 carboxy groups; and (iv) chelating agent; and (v) enzyme stabilizing metal ion system consisting of calcium ions and magnesium ions, present in a weight ratio of calcium ion to magnesium ion of from 1:1 to 4:1; and (vi) from 0% to 0.2% (by weight of said liquid composition) source of borate ions; and (b) a water-soluble polymeric material that is capable of being cross-linked by borate ions, preferably a water-soluble polymeric material comprising poly-vinyl alcohol.

Detergent product

The present invention relates to detergent compositions, especially liquid, granular and tablet forms of laundry detergent compositions, that comprise improved hydrotropes, wherein the hydrotropes are organic molecules in which two polar groups are separated from each other by at least 5 aliphatic carbon atoms; liquid compositions that contain such hydrotropes have a viscosity, dilution profile and dissolution behavior that render the product effective and convenient for use as a liquid laundry detergent composition.

Detergent compositions comprising hydrotropes

Water-soluble pouches comprise water-soluble films coated by a zeolite powder having a specific oil absorption of 0.4 ml/mor more. Processes for producing such pouches use a zeolite powder having a specific oil absorption of 0.4 ml/mor more for coating the water-soluble pouch.

A process for making a non-phosphate, zeolite-built detergent tablet, the process comprising a first step of providing a detergent composition, a second step of forming a particulate material comprising the detergent composition, and a third step of compressing the particulate material in a tablet form, the process being characterized in that it further comprises a step of cooling the detergent composition below ambient temperature between the first and the third step.

Production process for detergent tablet

The present invention relates to photochemical singlet oxygen generators having enhanced fabric substantivity, said photochemical singlet oxygen generators useful as photobleaches in laundry detergent compositions. the present invention is also directed to methods for removing stains on fabric by contacting dirty and stained fabric with the photobleaching agents described herein.

Photochemical singlet oxygen generators having cationic substantivity modifiers

The invention relates to photochemical singlet oxygen generators useful as bleaching agents or anti-microbial agents in laundry detergent compositions or in hard surface cleaning compositions. The singlet oxygen generators described herein have enhanced singlet oxygen generation due to aromatic moieties teed to the molecules, said aromatic moieties absorbing ultra violet radiation then re-emitting the radiation as fluorescence at a wavelength absorbable by the singlet oxygen producing photosensitizer unit. The increase in the number of photons having an absorbable wavelength provides an increase in the production of singlet oxygen.

Photochemical singlet oxygen generations having enhanced singlet oxygen yields

Photosensitizing compounds suitable for use as laundry detergent photobleaches are disclosed. The disclosed compounds are phthalocyanine and naphthalocyanines comprising axial moieties selected for their hydrophobic character as measured by their ClogP. Also disclosed are methods for bleaching fabrics and methods for disinfecting hard surfaces.

Photobleaching compositions effective on dingy fabric

The present invention relates to photochemical singlet oxygen generators useful as bleaching agents for laundry detergent compositions or in hard surface cleaning compositions and as anti-microbials. The photochemical singlet oxygen generators comprise a heavy atom unit-containing axial unit wherein the heavy atoms overlap with the &pgr; electron cloud of the photosensitizer unit and enhance the quantum efficiency of the transition of an electron from exited singlet state to triplet state.
