More Information
Summary: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 comprises the steps of (i) neutralising an anionic surfactant precursor with a source of alkali, (ii) adding Na2SO4 and Na2CO3 to form a slurry and (iii) spray-drying the obtained slurry to form a granule, whereby the molar ratio of Na2SO4 to Na2CO3 is in range of 1 : 0.9 to 1 : 1.3, and whereby the double salt Na2SO4.Na2CO3 is formed and whereby the slurry comprises a polycarboxylate polymer. There is also provided a spray-dried detergent carrier granule comprising at least 40% by weight of an anionic surfactant and suitable for use as a granular detergent composition or a component thereof, comprising (i) linear alkylbenzene sulphonate (LAS), soap and mixtures thereof, and (ii) the double salt Na2SO4.Na2CO3 obtainable by the process of the present invention. A third aspect is a detergent composition comprising such granules.
