Secret Physical and Chemical Residences

HPMC is a non-ionic cellulose ether made from natural cellulose. It liquifies quickly in cold water but does not liquify in warm water over its gelation temperature. The item develops clear, colorless solutions with great film-forming capacity. It stays steady over a large pH array (commonly 3– 11).

Thickness varies by grade. Common thickness varieties consist of 5 mPa · i te 100,000 mPa · i te 2% focus and 20 ° C. This enables customers to select the right kind for their specific demands– whether for enlarging, te taamuraa, or water retention.

Purity and High Quality Criteria

The product satisfies major pharmacopeial requirements, te USP-NF, EP, e JP, when used in pharmaceutical applications. For commercial use, it follows appropriate food and building sector standards.
