Patent ID: 7186678

Claim:
A process for making granules of a surfactant composition having an improved dissolution rate in cold water comprising: forming a composition comprising (a) a nonionic surfactant comprising a hydroxy mixed ether; (b) a disintegrator component selected from the group consisting of polysaccharides, polyvinyl pyrrolidones, polyurethanes, polyethylene glycols, alginic acids, alginates, and mixtures thereof; and (c) optionally at least one co-surfactant wherein a weight ratio of total surfactant to disintegrator component is in a range of 10:1 to 1:10; and (d) compacting the composition to form granules wherein less than 20% by weight of the granules have a particle size outside a range of 0.02 mm to 6 mm whereby surfactant granules with an improved dissolution rate in cold water are formed.
