SURFACTANT GRANULATES AND METHOD FOR PRODUCING SURFACTANT GRANULATES

WIPO Patent Application WO2003048286

A3

The invention relates to highly soluble surfactant granulates with varying bulk densities and excellent solubility profile that comprise the neutralized form of an anionic surfactant acid and sodium carbonate and sodium hydrogen-carbonate. These granulates are obtained by neutralizing anionic surfactant acids with solid neutralizing agents, said neutralizing agents comprising sodium carbonate that at least partially reacts to sodium hydrogen-carbonate. The percentage of the weight portions of sodium carbonate to sodium hydrogen-carbonate in the end products is 2:1 or more and the water content of the end product is < 15 % by weight, preferably < 10 % by weight, more preferred < 5 % by weight and particularly < 2.5 % by weight, when determined by loss on drying at 120 DEG C.
