摘要： Spray-dried granulates useful as washing or cleaning products or as components of such products, both for household and industrial use, contain at least 1 % by weight anionic surfactants and may have apparent densities of at least 550 g/l. These granulates may be produced by spraying slurries that contain saccharic acids or salts of saccharic acids. The use of saccharic acids or their salts at the same time lowers the viscosity of the slurries, so that more concentrated slurries may be sprayed, increasing the output of spraying towers without increasing their energy consumption.

摘要： Spray-dried granulates suitable as washing or cleaning agents or as components thereof, both for household and industrial use, have less than 550 g/l apparent density and contain 1 to 30 % by weight non-ionic surfactants, but less than 1 % by weight anionic surfactants and less than 0.2 % by weight soap. In order to increase their apparent density, saccharic acids or salts of saccharic acids are added. The use of said saccharic acids or their salts reduces at the same time the viscosity of the slurries, so that more concentrated slurries can be sprayed and the performance of the spraying tower plants can be increased without increasing energy consumption.
