摘要： The invention relates to a method for producing anionic surfactant granulates by simultaneous neutralization of acid anionic surfactants with bases, drying and granulation in a horizontal thin-layer evaporator or dryer, characterized in that the acid anionic tensides and/or bases are used as aqueous preparations with a solids content in such a way that the overall amount of water in the installation does not at any time exceed 15 wt. %.

摘要： The invention relates to a novel method for producing neutral sugar surfactant granulates, wherein aqueous alkaline-adjusted pastes containing a) alkyloligolycosides and/or alkenyloligoglycosides and/or (b) fatty acid N alkylpolyhydroxyalkyamides with a solids content of at least 20 wt. per cent are simultaneously dried in a horizontally arranged thin-layer evaporator or dryer with rotating fixtures until a residual water content of less than 2 wt. per cent is obtained and they are transformed into pieces. The inventive method is characterized in that the sugar surfactant pastes are neutralized immediately before entering the thin-layer apparatus. The products are characterized by a specially high color quality and storage stability.

摘要： The invention concerns a process for preparing solid raw materials for washing agents by simultaneously drying and granulating aqueous pastes of anionic and/or amphoteric surfactants in a horizontal thin film evaporator or drier with rotating fittings, the drying process being carried out at a temperature ranging from 120 to 130 °C. Hydrolysis-free, light-coloured, pourable products are obtained which have a uniform grain spectrum and high bulk density.
