2149403 9412259 PCTABS00032 A composition comprising a solution which comprises a hydrocarbyl polysaccharide, a non-ionic surfactant and an antifoam component, which antifoam component forms a separate phase on dilution with water, thereby reducing the foam which would normally arise from the hydrocarbyl polysaccharides, which is especially useful when it is necessary to spray the composition. The composition is useful as an adjuvant for example in agrochemical formulation, for example growth regulators, herbicides, and especially pesticides (such as insecticides, fungicides or acaricides), or as in the cleaning of hard surfaces, for example bottles. A concentrate and a corresponding dilute formulation e.g. for such purposes, in which an appropriate chemical agent is present, and processes for preparing and using the composition, concentrate and dilute formulation.
