Abstract
Free-flowing granular dispersing agents for use in water-dispersible granule (WDG) agricultural chemical formulations are a composite substance comprised of an alkyl polyglycoside and a polymeric anionic dispersant. The granular composite dispersing agents can be used in granular or liquid agricultural chemical formulations, exhibit outstanding attrition resistance, excellent dispersional stability after accelerated aging and low moisture content when made into a paste. The composite dispersing agents are useful as primary dispersants in dry agricultural formulations (wettable powders and water-dispersible granules) and in aqueous suspension concentrates.
