Abstract
1,220,998. Free-flowing washing powders. DEUTSCHE GOLD-UND SILBER-SCHEIDEANSTALT. 19 March, 1968 [25 March, 1967], No. 13176/68. Heading C5D. A process for the production of a free-flowing washing powder mixture comprises (a) spraying into a free-fall zone an active-oxygen compound (e.g. alkali metal perborate) which can be fused in its own water of crystallization, the compound being sprayed in the form of a melt and the melt optionally containing additional water over and above the water of crystallization, and (b) blowing into the resultant spray cone a solution, suspension or powder containing washactive substances (i.e. surfactants), washing auxiliaries (i.e. substances which, although not surfactants, take part in or assist the washing action, for example silicates, polyphosphates, soda and cellulose glycolates) and optionally other additives. A granulate is removed from the end of the free-fall zone and may subsequently be dried. According to a modification of the process, all or part of the wash-active substances are mixed with the melt of activeoxygen compound prior to spraying. In the case of alkali metal perborate melts, 0À5-5% by weight (based on the perborate) of watersoluble compounds of magnesium, cadmium or zinc (e.g. magnesium chloride) may be added as stabilizer and the perborate melt may have been formed by reaction between metaborate and hydrogen peroxide. In examples, the preparation of washing powders containing such ingredients as sodium perborate, sodium silicate, sodium sulphate, sodium pyrophosphate, sodium tripolyphosphate and alkyl sulphate or alkyl benzene sulphonate surfactants is described.
