Abstract
A new method for evaluating the agglomerating property of granular detergents was devised. It is useful for comparing commercial products, screening new products, and for studying anticaking agents. This method differs from prior methods, as detergent is fluidized by conditioned air in a reverse conical tower, and agglomeration is evaluated from the lowering of level of fluidized particles because of agglomeration. The height of the fluidized particles is inversely proportional to particle size, and the level of fluidized particles becomes lower more rapidly with ease of agglomeration. The coefficient of variation (σ/−x) of the method is about 10%, and it is shown that the method coincides with the tendency of detergents to agglomerate in the carton.
