FIELD: soap industry.
SUBSTANCE: invention relates to preparing detergent granules by spray drying process, wherein detergent granules are obtained by bringing in contact, in fluidized bed granulator, acidic precursor of anionic surfactant, sulfuric acid, and a solid carbonized neutralizing agent having average particle size d3.2 between 10 and 50 μm. Amount of sulfuric acid constitutes at least 50% of the total weight of anionic acidic precursor and sulfuric acid.
EFFECT: reduced volume density and improved tackiness and volume compaction percentage.
