Abstract (en)
[origin: WO2014009101A1] There is provided a process for the production of a detergent granule comprising at least 40% by weight of an anionic surfactant and suitable for use as a granular detergent composition or a component thereof, which process comprises the steps of (i) mixing an anionic surfactant precursor with a source of alkali to form a neutralised paste, (ii) adding alkali metal salt of a polycarboxylic acid, up to 5% by weight alkaline silicate, polycarboxylate polymer and sodium carbonate to form a slurry and (iii) spray-drying the obtained slurry to form a detergent granule having an amorphous phase content of more than 60% by weight, whereby the molar ratio of the alkali metal salt of a polycarboxylic acid to sodium carbonate is in range of 0.4 to 1.6. There is also provided a spray-dried detergent granule comprising at least 40% by weight of an anionic surfactant, alkali metal salt of a polycarboxylic acid, up to 5% by weight alkaline silicate, polycarboxylate polymer and sodium carbonate and suitable for use as a granular detergent composition or a component thereof, obtainable by the process of the present invention. A third aspect is a detergent composition comprising such granules.
