Dissolving process
HPMC will agglomerate when directly added to water and then dissolve. In this way it dissolves very slow and hard. Suggested methods as followers:
1. In hot water.
HPMC does not dissolve in hot water. The primary HPMC can be uniformly disperse in hot water. Then cool down in two ways:
A) Add hot water in container and heated to over 70 centigrade. Add HPMC gradually while slowly, stir. At the beginning, HPMC float on the top of water, then turns into slurry state stir and cool down.
B) Add water in container to 1/3 or 2/3 of its content. Heated to over 70 centigrade add HPMC by sequence of a). Make it disperse to form slurry state. Add cool water or ice to the resideual content, stir and cool down the mixture.
2. Powder combination.
Mix HPMC with identical volume of other powder, disperses them sufficiently then add water to the
