HPMC E5

KimaCell®Hypromellose E5 is pharma grade hydroxypropyl methyl cellulose,
pharmaceutical excipients play an important role in the development and
production of formulations. For example, in sustained-release preparations,
polymer materials such as cellulose ether are used as pharmaceutical excipients
in sustained-release pellets, various matrix sustained-release preparations,
coated sustained-release preparations, sustained-release capsules, sustained-
release drug films, and resin drug sustained-release preparations. Preparations
and liquid sustained-release preparations have been widely used. In this
system, polymers such as cellulose ether are generally used as drug carriers to
control the release rate of drugs in the human body, that is, it is required to
release slowly in the body at a set rate within a certain time range to achieve
the purpose of effective treatment.

HPMC E5 Uses

KimaCell® hydroxypropyl methylcellulose e5 are basically in the middle and
high-end fields of the pharma industry, with high added value. Due to strict
quality requirements, the production of pharmaceutical-grade cellulose ether is
also relatively difficult. It can be said that the quality of pharmaceutical
grade hydroxypropyl methylcellulose products can basically represent the
technical strength of cellulose ether enterprises. Cellulose ether is usually
added as a blocker, matrix material and thickener to make sustained-release
matrix tablets, gastric-soluble coating materials, sustained-release
microcapsule coating materials, sustained-release drug film materials, etc.

Natural cellulose ether is a general term for a series of cellulose derivatives
produced by the reaction of alkali cellulose and etherifying agent under
certain conditions. It is a product in which the hydroxyl groups on cellulose
macromolecules are partially or completely replaced by ether groups.
