Hygroscopicity and agglomerativity of sodium dodecylbenzenesulfonate-sodium sulfate system were determined at 35°C, and 48.592.0, and 80.090.0% relative humidities respectively.<BR>The seven sulfonates containing various structures, described in the previous report were used, and the test materials were prepared by spray-drying with sodium sulfate.<BR>The hygroscopicity increases as the aromatic nucleus is located near the center of the alkylchain, or as the side chain is more branch d. The agglomerating rate which was determined by specialy designed appratus has the same trend as the hygroscopicity.<BR>It was shown that there is a correlation between hygroscopicity and agglomerativity of the dodecylbenzenesulfonate-sodium sulfate systems.
