DETERGENT OR CLEANSING AGENT, COMPOSITE OR TREATED PARENT PRODUCTS FOR THEIR PREPARING AS FORMED PARTICLES AND METHOD OF THEIR PREPARING Russian patent published in 2003 - IPC

FIELD: detergents. SUBSTANCE: invention relates to method of preparing rapidly dissolving, thickened, formed particles of detergent or cleansing agents or composites or treated parent products for their preparing, respectively, and to detergent or cleansing agents prepared by this method that characterized by enhanced consumption's quality. Indicated method involves preparing a preliminary mixture comprising separate parent components and/or composites at the room temperature under normal pressure (1 bar) as solid form with melting point 45 C, not below; at least one anionic surface- active substance and at least one water-soluble binding agent that is taken among group including the following components: modified branched and linear polyethylene glycols, 1,2-polypropylene glycols, low- molecular polyvinyl-pyrrolidones, oxyalkylated saturated alcohols and oxo-alcohols, oxyethylated fatty acid methyl esters, branched and linear oxyethylated fatty acids, compounds containing hydroxyl groups and functional groups of ethers, swollen anhydrous polymers, alkylglycosides of the general formula RO(G)_x, fatty acid polyhydroxylated amides and their mixtures taken in the amount from 2 to 15 wt.-% (as measured for preliminary mixture). Binding agent is in solid form at temperatures below 45 C and under pressure 1 bar and under conditions of processing as melt and total water content in preliminary mixture does not exceed 15 wt.- % being this water is not in free liquid form. Then preliminary mixture is converted to formed particles with filled weight above 600 g/l using pressure at temperature 45 C, not less. EFFECT: improved method of preparing. 20 cl, 2 tbl
