    Abstract: There is prepared an aqueous stable suspension of a water insoluble silicate capable of binding calcium ions and it is used for the production of washing and cleaning agents. The suspension contains in addition to water components A and B wherein component A is a silicate capable of binding calcium and having the formula (Cat2/nO)x-Me2O3x(SiO2)y I and component B is a dispersing agent comprising a mixture of at least two fatty alcohols polyglycol ether based on isotridecyl alcohol or another aliphatic C13 alcohol and ethylene oxide having the following properties: (a) Fatty alcohol polyglycol ether having 4.5 to 5.5 EO units -Turbidity point DIN 53917 56 to 60 DEG C. -Solidification point +4 to -25 DEG C. -Viscosity at 50 DEG C. 13 to 28 m Pas -Density at 50 DEG C. 0.94 to 0.96 g/ml - (b) Fatty alcohol polyglycol ether having 6 to 8 EO units -Turbidity point DIN 53917 66 to 74 DEG C. -Solidification point +12 to -16 DEG C. -Viscosity at 50 DEG C. 18 to 28 m Pas -Density at 50 DEG C. 0.96 to 0.98 g/ml -

    Abstract: Aqueous bleaching agent suspensions based on a water-soluble peroxycarboxylic acid suspended in a carrier liquid in the presence of an organic thickening agent and of an acidifying agent exhibit an improved storage resistance over known suspensions with this base. This is achieved by means of pourable to pasty bleaching agent suspensions which contain a xanthan polysaccharide or agar polysaccharide as thickening agent and, in addition, a hydrate-forming neutral salt which desensitizes peroxycarboxylic acids. Preferred suspensions exhibit a pH of 2-5 and contain 10-30% by wt. diperoxydodecanedioic acid, 5-20% by wt. sodium sulfate and 0.1-1.0% by wt. xanthan. The use of non-dried, hydrophilized and optionally in situ desensitized peroxycarboxylic acids is especially preferred. The bleaching agent suspensions are prepared by homogeneously suspending the peroxycarboxylic acid in the thickened carrier liquid. The storage-resistant bleaching agent suspensions are used as laundry bleaching agents and for preparing cleaning agents and disinfection agents.

    Abstract: The adsorbent has a high absorption capacity for liquid to pasty ingredients of detergents and cleaners and has the following components: (a) 60 to 80 per cent by weight of a synthetic sodium silicate which is capable of cation exchange and contains bound water, (b) 0.1 to 8 per cent by weight of sodium silicate of the composition Na2O : SiO2 = 1 : 2 to 1 : 3.5, (c) 3 to 15 per cent by weight of a mixture of two different polyacrylic acids which have a different viscosity number, (d) 8 to 18 per cent by weight of water which can be removed at a drying temperature of 145 DEG C, (e) 0 to 5 per cent by weight of a nonionic surfactant containing polyol ether groups, where the adsorbent has an average particle size of 0.2 to 1.2 mm and the particles with a size of less than 0.05 mm do not comprise more than 2 per cent by weight and the particles with a size of more than 2 mm do not comprise more than 5 per cent by weight, and the bulk density is 400 to 700 g/l.
