HPMC CAS NO.9004-65-3

HPMC CAS NO.9004-65-3 can be widely used for pharmaceutical field,construction field and industry field.

HPMC CAS NO.9004-65-3 

HPMC is water-soluble polymer which is produced by treating water-insoluble cellulose chemically. HPMC when dissolved in water, offers a variety of functions such as thickening, surface activity, protective colloid, water retention, shape retention etc. And these functions have been used in wide variety of fields from pharmaceuticals, food, civil engineering and construction industry, ceramics, cosmetics etc.

 Application

This product is a multi-purpose medicinal materials can be used as thickener, dispersant, emulsifier and film-forming agent. Made in the drug tablet film coating, adhesive, can significantly improve the dissolution rate of drugs can enhance the waterproof tablets. Also as a suspension, ophthalmic preparations, controlled release formulations such as skeletons and floating tablets. HPMC and other synthetic polymers and colloidal drug binding, can prevent water and alcohol drugs from the transparent gel to separate the water and improve water retention, is also being food, cosmetics and other areas used as a thickener, emulsifier and improve Rheological properties, as well as to other daily-use chemical industry, etc. Currently this product has become the main material for plant capsule.And also  HPMC can be applied to building materials and material

for PVC.

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  to the water.
