2.  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. 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 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

3. Purpose of Application

HPMC,a multipurpose additive for pharmaceutical, can be functioned as thickener, dispersant, emulsifier, film forming agent, etc. It is used in tablets for dressing and binding to improve solubility of the drugs and reinforce tablets’ water prevention function. It can also be utilized as mixed suspending agent, additive for eye drops, sustainedrelease agent, etc. HPMC can be widely used in the fields of detergent and cosmetics industries as thickener and emulsion stabilizer to improve rheologic property. 

HPMC can be directly applied to food not only as emulsifier, binder, thickener or stabilizer, but also as packing material.

4. Packing

Net wt 25kgs in cardboard drum with PE lining or coated PP woven bag, stored indoors in dry and draughty place ;
