  • Patent number: 6518234
    Abstract: A process for the production of detergent particles, comprises feeding an acid precursor of an anionic surfactant and a neutralising agent into a horizontal thin-film evaporator/drier comprising a mixing region, a drying region and a cooling region. The resultant detergent particles are graded to separate an oversize granule fraction in which at least 70 wt % of the particles have a minimum diameter of 1000 &mgr;m. This fraction is fed back into the process.

  • Patent number: 6514930
    Abstract: A process for the production of detergent particles comprises feeding an acid precursor of an anionic surfactant, a neutralizing agent and aluminosilicate detergency builder into a horizontal thin-film evaporator/drier. The evaporator/drier comprises a mixing region, a drying region and a cooling region. Neutralization of the acid precursor is effected, together with granulation, drying and cooling, to form the detergent particles. At least some of the aluminosilicate builder is fed into the thin-film evaporator/drier between the drying region and the cooling region and/or into the cooling region. When all of he aluminosilicate builder is fed into the cooling region, the aluminosilicate is in an amount of more than 20% by weight of the particles exiting the cooling region.

  • Publication number: 20030022808
    Abstract: In order to improve the dispersion of nonionic surfactant into wash water from a granule in which the nonionic surfactant is carried on a water-insoluble granular material, the nonionic surfactant is intimately mixed with a structurant which is a non-soap ionic surfactant in finely divided particulate form. A preferred structurant is an anionic surfactant, for example, primary alcohol sulphate.
