Sodium carboxymethyl cellulose CMC physical and chemical properties

1. hygroscopicity Carboxymethylcellulose sodium CMC has the same water absorption as other water-soluble glues. Its humidity balance increases with the increase of humidity and decreases with the increase of temperature. The higher the D.S, the greater the air humidity, and the product’s The str... Read More

Application of hydroxypropyl cellulose in solid preparation

Hydroxypropyl cellulose, a pharmaceutical excipient, is divided into low-substituted hydroxypropyl cellulose (L-HPC) and high-substituted hydroxypropyl cellulose (H-HPC) according to the content of its substituent hydroxypropoxyl group. L-HPC swells into a colloidal solution in water, has the pro... Read More

Properties of Cationic Cellulose Ether Solution

Properties of Cationic Cellulose Ether Solution The dilute solution properties of a high-charge-density cationic cellulose ether (KG-30M) at different pH values were studied with a laser scattering instrument, from the hydrodynamic radius (Rh) at different angles, and the root mean square radius ...

What is the viscosity of hydroxypropyl methylcellulose hpmc?

What is the viscosity of hydroxypropyl methylcellulose hpmc? Putty powder for interior walls generally has a viscosity of 100,000. The cement mortar has higher requirements for adjustment, and the viscosity of 150,000 is easy to use. In addition, the most critical role of HPMC is to lock water, f... Read More

Instant type hydroxypropyl methylcellulose

Instant type hydroxypropyl methylcellulose 1. The water content is too high, resulting in too low content, which is equivalent to reducing the concentration of the solution. 2. The viscosity is low, and some marked viscosity does not match the actual viscosity. 3. Stir even after adding the ingre... Read More
