The reaction product is usually soluble or at least dispersible in the molten vehicle. Some plastic coatings are water dispersible to aid recycling and repulping. Using surfactant dopants, the polyaniline can be made dispersible and hence useful for practical applications. Coartem Dispersible contains the same ratio of artemether and lumefantrine as Coartem. Third, the source should be sufficiently dispersible to effectively contaminate the area around the explosion.
