3. Viscosity Specification

Note: Any other special requirement for the product can be satisfied through the negotiation.

【Properties】

Achieving a desired drug-release profile has traditionally involved blends of different molecular weights of particular polymers. Blending, however, can increase release-profile variability. HPMC is developed to obviate the need for blending and offer a potential solution to the problem of dissolution variability.

Features and Benefits:

- Increase predictability and reproducibility of drug release profiles
- Decrease research and development time needed to optimize blend ratio
- Decrease manufacturing time- no need to blend and manage multiple raw materials
- Opportunity to develop custom excipients

【Packaging】

HPMC pharma grade is packed in 2 layer LDPE bag and sealed in the Drum, it is very safe to store and transport. the standard packing is 25kg/drum

【Transportation and Storage】

The product should be kept in the original bag and stored in the dry and clean place far away from the source of heat and not put together with other chemicals .
