摘要: Particulate high bulk density non-spray-dried detergent compositions containing organic non-soap surfactant, zeolite builder and fatty acid soap as powder structurant, prepared by non-tower mixing and granulation processes involving in-situ neutralization of fatty acid to soap with aqueous sodium hydroxide, can suffer from localized particle yellowing on storage when perfume and/or fluorescer are present, due to the presence of areas of high alkalinity. Yellowing is reduced without loss of powder structuring if a defined, less than stoichiometric amount of sodium hydroxide is used for the fatty acid neutralization. Surprisingly, in bleaching powders improved bleach stability is also observed. The resulting powder can be defined in terms of a low "basic sodium" content.
