A method of treating coloured fabrics with a luminance (L*) less than 50, preferably black garments, which comprises contacting the fabrics with a wash liquor comprising 0.001-0.1 g/L of a hydroxyl C2-C4 alkyl derivative of a beta 1-4 polysaccharide, which is preferably hydroxyethyl cellulose, and a surfactant.

Method of laundering coloured fabrics

A liquid detergent formulation comprising:

Fabric detergent compositions

A laundry treatment composition comprising a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during a treatment process wherein the material undergoes during the treatment process, a chemical change by which change the affinity of the material for the fabric is increased.

Laundry treatment for fabrics

A built laundry detergent composition containing cationic detergent surfactant also contains from 0.05 to 5 wt % of iminodisuccinate (IDS) or hydroxyiminodisuccinate (HIDS). The composition provides improved moil and stain removal in conjunction with reduced dye fading of coloured fabrics.

Detergent compositions containing a cationic detergent and builder

A detergent composition having excellent color care properties when used to launder colored fabnrics. The composition comprises a dye transfer inhibiting polymer comprising one or more monomeric units containing at least one .dbd.N--C(.dbd.O) with the proviso that the dye transfer inhibiting agent does not comprise an -oxide group and a water soluble sunscreen.

Detergent composition comprising dye transfer inhibiting polymer and

An aqueous liquid detergent composition is substantially transparent in the absence of opacifier contains a sunscreen together less than 5 wt. % of detergency builder and/or comprises a water-miscible polar organic solvent. The solvent and fluorescer or ultraviolet absorbing agent are mixed together as a premix prior to incorporation in the composition as a whole.

Liquid detergent compositions and process for their preparation

The present invention relates to perfumed compositions comprising polymer and nonionic surfactant and is explained with particular reference to insect-repellent compositions which are a preferred embodiment of the invention. The invention provides an aqueous cleaning composition comprising: a nonionic surfactant, a carboxylate polymer, and, a perfume. Preferably the compositions of the invention are aqueous cleaning composition of pH 3.5-5.5 comprising:

Perfumed compositions comprising polymer and nonionic surfactant

A detergent composition which reduces the photofading of fabric. The detergent composition comprises a cationic UV-absorber and an anionic surfactant.

Fabric treatment compositions

A rinse conditioner giving excellent deposition of a fabric treatment agent onto fabric. The rinse conditioner comprising a fabric softening compound, a water insoluble oil and from 0.1% to 10% by weight of the total composition of a Fabric Treatment Agent, wherein the Fabric Treatment Agent has a c.logP of 3.0 or more.

Fabric conditioning composition

A laundry treatment product, in the form of a sachet containing a particulate bleaching detergent composition containing sodium percarbonate, has at least two compartments to enable the sodium percarbonate to be segregated from certain other ingredients, particularly zeolites. The sachet product exhibits improved bleach stability on storage. Sachets of water-soluble polyvinyl alcohol film are not insolubilized in the wash liquor since no sodium perborate is present to generate insolubilizing borate ions.

Laundry treatment product

A laundry treatment product, in the form of a single-compartment of multicompartment sachet capable of releasing its contents into the wash liquor during the laundry process, contains a particulate laundry treatment composition including a quaternary ammonium- or phosphonium-substituted bleach precursor, for example, cholyl-4-sulphophenyl carbonate, optionally together with a peroxy bleach compound and optionally together with one or more detergent ingredients. The sachet may be a self-contained whole wash product, or a bleach adjunct for use in conjunction with a separate detergent composition.

A stable heavy metal adjunct, particularly manganese adjunct, for use as a peroxygen bleach catalyst is disclosed which comprises a matrix of a heavy meal salt provided with a surface powder coating of desiccant microsized powdered material having a mean particle size of less than 25 .mu.m. A process for preparing said adjunct and bleaching and detergent compositions containing said adjunct are also disclosed. Preferred heavy metal is manganese and preferred surface powder coating is with microsized silicon dioxide (silica).

Heavy metal adjuncts, their preparation and use

A stable manganese adjunct for use as a bleach catalyst is obtained by having a manganese (II) cation bound to a 'ligand' forming either a true complex compound, a water-insoluble salt compound, or an ion-binding compound by absorption, which compound is then protectively embedded in a matrix of water-soluble or water-dispersible material. The adjunct is particularly suitable for incorporation in fabric-washing powder compositions containing a peroxide bleach without causing instablity to the composition and brown discoloration due to MnO.sub.2 formation.

Manganese adjuncts, their preparation and use

A photobleach system is disclosed comprising a synergistic mixture of an electron donor and a visible/ultraviolet radiation absorbing compound (a chromophore acceptor) which is capable of, in an excited electronic state, undergoing electron transfer from said electron donor. A composition comprising said photobleach system and use of the system or composition in bleaching dyes and textiles are also disclosed. A preferred electron donor is sodium sulphite. Preferred chromophore acceptors are water-soluble metallated phthalocyanines and naphtalocyanines.
