A process for making neutral sugar surfactant granules involving: (a) providing a water-containing alkaline sugar surfactant selected from the group consisting of an alkyl oligoglycoside, an alkenyl oligoglycoside, a fatty acid-N-alkyl polyhydroxyalkylamide, and mixtures thereof; (b) providing a thin-layer evaporator or dryer having rotating internals; (c) neutralizing the water-containing alkaline sugar surfactant to a pH of from 6.8 to 7.5 to form a neutralized water-containing sugar surfactant; (d) introducing the neutralized water-containing alkaline sugar surfactant into the thin-layer evaporator or dryer; and (e) drying the water-containing alkaline sugar surfactant in the thin-layer evaporator or dryer until it has a residual water content below 2% by weight.

Method for producing neutral sugar surfactant granulates

A process for producing solid detergent granular materials is presented involving (a) forming an aqueous surfactant paste of an anionic surfactant, an amphoteric surfactant or mixtures thereof, and (b) drying and granulating the aqueous paste in a horizontal thin-layer evaporator or dryer having rotating fittings, wherein the drying is carried out at a temperature of 120&deg; C. to 130&deg; C. The process produces granules having a bulk density greater than 600 grams/liter and a uniform particle size distribution.
