4. How can the quality of hydroxypropyl methylcellulose (HPMC) be determined easily and visually?
(1) Specific gravity: The higher the specific gravity, the better the quality.
(2) Whiteness: Most quality products have a good whiteness. Except for those with added whitening agents. Whitening agents can affect the quality.
(3) Fineness: The finer the fineness, the better the quality. The fineness of our HPMC is usually 80 mesh and 100 mesh, 120 mesh is also available.
(4) Transmittance: Put HPMC into water to form a transparent gel and observe its transmittance. The greater the transmittance, the less insoluble material. Vertical reactors usually have better transmittance and horizontal reactors have poor transmittance, but this does not mean that the production quality of vertical reactors is better than that of other production methods. There are many factors that determine the quality of the product in horizontal reactors, which have a high hydroxypropyl content and a high hydroxypropyl content, which is best for water retention.
