Machine cleaner product in the form of a water-soluble single- or multi-compartment pouch comprising a limescale removing composition and a water-soluble enveloping material.

Liquid cleaning composition (I), comprises: an anionic surface-active; and an electrolyte a cross linked copolymer (II) of methacrylic acid and alkyl acrylate (with 1-4 carbon) (lower than 0.5 wt.% of active material compared to the total weight of (I)), in an aqueous medium. Liquid cleaning composition (I), comprises: an anionic surface-active; an electrolyte a cross linked copolymer (II) of methacrylic acid and 1-4C alkyl acrylate (lower than 0.5 wt.% of active material compared to the total weight of (I)), in an aqueous medium; provided composition is different from the formulation comprising Carbopol aqua SF-1(30%) (RTM; acrylate compolymer) (0.9 wt.%), Atlas G-4280(72%) (RTM; polyethylene glycol-80 sorbitan laurate) (4.58 wt.%), Tegobetaine L7V(30%) (RTM; cocoamidopropyl betaine) (11.33 wt.%), Glycerin 917(99%) (99%) (RTM; glycerin) (1.9 wt.%), Polymer JR-400(RTM; polyquaternium-10) (0.14 wt.%), Dowicil 200(RTM; quaternium-15) (0.05 wt.%), Versene 100 XL(RTM; tetrasodium EDTA) (0.263 wt.%) and water (to make 100 %). An independent claim is also included for cosmetic process of cleaning of stain residues on human keratinous material, comprises applying (I) on the keratinous material, in the presence of water, and allowing to form a foam and eliminating the formed foam and the stain residues by rinsing with water.

A method is provided for forming an active material containing coating on a substrate. The substrate is suitably a wipe, cloth or sponge for household use, or a water-soluble household cleaning unit dose product. The method comprises the steps of: i) introducing one or more gaseous or atomised liquid and/or solid coating-forming materials which undergo chemical bond forming reactions within a plasma environment and one or more active materials which substantially do not undergo chemical bond forming reactions within a plasma environment, into an atmospheric or low pressure plasma discharge and/or an excited gas stream resulting therefrom, and ii) exposing the substrate to the resulting mixture of atomised coating-forming and at least one active material which are deposited onto the substrate surface to form a coating.

A cleaning tablet which has a plurality of discrete regions with differing compositions, characterised in that at least one first region of the tablet comprises at least 50 wt% (based on the weight of said region) of non-soap anionic surfactants;from 1 to 20 wt% (based on the weight of said region) of structurant materials; and from 1 to 30 wt% (based on the weight of said region) of diluent materials.

Disclosed are hand-held scrubbing devices of the type having a replaceable pad. These devices have a handle which is extruded and extremely flexible. The pads are multi-layer and may be pre-impregnated with a cleaner concentrate. A shipping/docking container for use therewith is also disclosed which has the capability of reducing its overall size once the product has reached the consumer.

The invention relates to a process for the preparation of a detergent containing one or more compounds having the formula RCONH(C₂H₄O)nCH₂COOH and/or salts thereof, where R represents a linear or branched aliphatic hydrocarbon group with 5-21 carbon atoms and n is a number from 1-20, by amidating, ethoxylating and carboxymethylating one or more fatty acids having the formula RCOOH and, if so desired, converting all or part of the ether carboxylic acid obtained to a salt thereof, characterised in that an oil or fat is started from and that this oil or fat is aminolysed in the presence of an alkali(ne earth) metal and the reaction mixture obtained is in the usual manner ethoxylayed, carboxymethylated and, if desired, converted in whole or in part to a salt.

A purifying agent for purifying soil or ground water which comprises a water suspension containing iron composite particles comprising ±-Fe and magnetite, and having an average particle diameter of 0.05 to 0.50 µm, an S content of 3500 to 10000 ppm and an A1 content of 0.10 to 1.50% by weight, and polyaspartic acid or a salt thereof. The purifying agent is capable of decomposing aliphatic organohalogen compounds or aromatic organohalogen compounds contained in the soil or ground water in an efficient, continuous and economical manner.
