Abstract
A hydrocolloid product having improved dispersibility and wettability characteristics in aqueous medium is provided by dry blending in a heated state the hydrocolloid powder particles with molten, normally solid nonionic surfactant. The heated mixing state is at a temperature greater than the melting temperature of the solid nonionic surfactant. After suitable mixing, the resulting mixture of surfactant-coated powder particles is extruded to produce granules of the hydrocolloid-nonionic surfactant mixture, which granules are cooled to below the melting temperature of the nonionic surfactant to provide a readily water dispersible, readily wettable hydrocolloid product.
