There are disclosed co-granules coated with hydroxymethyl cellulose and containing: b1) cyclic sulfonimine, b2) bleach activator selected from the group consisting of tetraacetylethylenediamine, decanoyloxybenzoic acid or mixtures thereof, and b3) carboxymethyl cellulose as binder, wherein the binder consists of the carboxymethyl cellulose of component b)3 which has a solubility of at least 1 g of carboxymethyl cellulose in 1 L of water at 25&#xb0; C. and wherein the coating comprises hydroxymethyl cellulose in an amount of from 5 to 20 wt. % of the coated co-granules.

Co-granules, detergents and cleaning agents and use thereof

The present invention provides granules containing one or more bleaching catalysts selected from the group of manganese salts or manganese complexes and at least one binder selected from the group of acid organic compounds coated with 0.1 to 3% by weight, referring to the total amount of the granules, with a polyvinyl alcohol-containing coating, wherein the coating comprises at least 80% of polyvinyl alcohol or mixtures thereof, in relation to the total weight of the coating.

Coated granules, use thereof, and washing and cleaning agents containing same

Disclosed are compounds of formula (I)(ROOC)&#x2014;R(OH)&#x2014;COO&#x2014;(CH&#x2014;O)&#x2014;OC&#x2014;R(OH)&#x2014;(COOR)&#x2003;&#x2003;(I)wherein Rand Rindependently of one another are hydrogen, a metal cation, an ammonium cation, C-C-alkyl, cycloalkyl with three to nine ring carbon atoms, aryl with five to ten ring carbon atoms, aryl that is substituted with one or two alkyl groups, aryl that is connected via an alkylene group with the carboxyl group, &#x2014;(CH&#x2014;O)&#x2014;H or &#x2014;O&#x2014;R(COOR1),Rand Rindependently of one another are aliphatic hydrocarbon residues with one to eight carbon atoms,a and b independently of one another are integers from 1 to 4,c is an integer from 0 to 4,d is an integer from 1 to 4,n is 2, 3 or 4, andm is 1, 2, 3 or 4, with the proviso thatRand Rmay be different within a molecule within the given definitions. These compounds are characterized by a very good complexation power for metal cations and can be used in detergents and cleaning agents, in oil extraction and for water softening.
