Abstract: A method for manufacturing an automatic dishwashing composition in the form of a non-aqueous gel, the method comprising: (i) combining one or more non-ionic surfactants, a polar non-aqueous solvent and a rheology modifier to form a non-aqueous gel, the non-aqueous gel having a pH of less than 7 when measured as a dilution of 1 part in 100 parts of water by weight, wherein the rheology modifier is an alkali-swellable emulsion polymer or a hydrophobically-modified alkali-swellable emulsion polymer; and (ii) adding to the non-aqueous gel one or more active agents selected from the group consisting of builders, surfactants, polymers, enzymes, bleaching agents, bleach activators, bleach catalysts and corrosion inhibitors to form the automatic dishwashing composition.
Abstract: A method of making a detergent composition including the following steps in the recited order: providing an aqueous composition comprising a citrate salt; lowering the pH by adding a first, un-neutralized or partially neutralized, polyacrylic acid having a weight average molecular weight in the range of 1000 to 6000 to form a second mixture; increasing the pH by adding alkali metal carbonate and/or alkali metal bicarbonate to form a third mixture; and adding a second polyacrylic acid having a weight average molecular weight in the range of 1000 to 6000 to form a fourth mixture; wherein the detergent composition is preferably an automatic dishwashing detergent composition or a laundry detergent composition.

Abstract: A composition comprising: from 25 to 80 wt % of at least one vinyl acetate-vinyl alcohol copolymer, where the copolymer comprises at least 85 mol % vinyl alcohol units; from 1 to 25 wt % of at least one polyhydric alcohol; and from 5 to 50 wt % of a first active agent which is: a polymer comprising a monomer having at least one carboxylic acid group or a salt or ester thereof; a polymer comprising a monomer having at least one imine group or a salt thereof; or a polymer comprising a monomer having at least one aspartic acid group or a salt or ester thereof. A package containing the composition. A method of preparing the composition, the method comprising extruding the composition. A method of machine dishwashing, wherein the first active agent is released into wash water over the course of a plurality of dishwashing programs.

Abstract: A method of manufacturing an automatic dishwashing detergent product, provided as a discrete dosage unit and comprising a continuous, non-aqueous gel phase, includes manufacturing the gel phase by free radical polymerisation of monomer(s) in a non-aqueous reaction mixture to form a polymeric builder. The reaction mixture comprises at least one non-ionic surfactant which is an optionally end-capped alcohol alkoxylate; and one or more monomers comprising acrylic acid and optionally one or more further ?,?-ethylenically unsaturated acids, wherein no more than 0.1 wt % of the total amount of the monomer(s) are crosslinking monomer(s).

Abstract: A detergent composition comprising a subtilisin variant having the amino acid sequence set forth in SEQ ID NO: 1, and at least one additional ingredient selected from i) bleaches selected from percarbonates, persulphates and organic peracids, ii) aminocarboxylates, or iii) sulphonated polymers, or iv) organophosphoric acids or salts thereof and mixtures thereof is provided. Also provided is a detergent composition comprising a subtilisin variant having the amino acid sequence set forth in SEQ ID NO: 1, wherein the detergent composition is at least partially enveloped in a water soluble or water dispersible package. The compositions exhibit good performance on proteinaceous stains, even when formulated at alkaline pHs. A method of removing proteinaceous stains from surfaces comprising such stains is also provided.
