Physicochemical comparison between microcrystalline cellulose and silicified microcrystalline cellulose

International Journal of Pharmaceutics, 1998
Abstract Silicified microcrystalline cellulose (SMCC) has been compared with a standard grade of microcrystalline cellulose (MCC) using several physicochemical techniques in order to elucidate any chemical or polymorphic changes in the material that could be attributed to the silicification process.

Microcrystalline Cellulose (MCC or Cellulose Gel)

2022
Microcrystalline cellulose (MCC) is one of the few relatively new ingredients available to the food industry. The manufacturing process most common to microcrystalline cellulose produced two divergent products. The first type of product is powdered microcrystalline cellulose.

True Density of Microcrystalline Cellulose

Journal of Pharmaceutical Sciences, 2005
Microcrystalline cellulose (MCC) exhibits unusual tableting properties, sometimes, inconsistent with its high plasticity. It is found that some of the unusual tableting properties of MCC can be explained in part by the use of inaccurate true density during tableting data analysis.

Thin-layer chromatography on microcrystalline cellulose

Journal of Chromatography A, 1965
Abstract “Avirin”, or “Avicel”, a microcyrstalline form of cellulose, has been with success in this laboratory for thin-layer chromatography. The material is employed without a binder and has, in this laboratory, essentially completely displaced the papergram because its speed, quality of separation, and the ease with which preparative plates may be ...

Rheology of Microcrystalline Cellulose-Carboxymethylcellulose Gels

Journal of Pharmaceutical Sciences, 1968
Rheological evaluations of MCC-CMC gels were employed to delineate their properties. It was concluded that the thixotropic nature of MCC-CMC gels depended upon the adsorption of the soluble CMC on the MCC. A certain degree of shear was required to unsheave the microcrystals. However, excessive shear reduced the degree of structuring.

Directional Bonding in Compacted Microcrystalline Cellulose

Drug Development and Industrial Pharmacy, 2001
The mechanical properties of compacts of microcrystalline cellulose (MCC) and silicified microcrystalline cellulose (SMCC) were evaluated by tensile testing, diametric compression testing, and compression testing. For tensile and compression testing, cubic specimens were carefully machined from MCC and SMCC compacts, and the tensile and compression ...

Microcrystalline Cellulose: An Overview

2017
Microcrystalline cellulose (MCC) is obtained from naturally occurring cellulose that has been purified and partially depolymerized. MCC is an excipient with wide-ranging applications in the pharmaceutical industry. Particularly, in the process of extrusion–spheronization, MCC has shown unsurpassed efficiency in terms of process control and end-product ...

Coagulation of microcrystalline cellulose dispersions

Journal of Colloid and Interface Science, 1989
Abstract The effect of particle shape on some aspects of the coagulation behavior of rod-like microcrystalline cellulose (MCC) dispersions is discussed. It is shown, by means of elementary DLVO theory and an ad hoc approximation for the angular dependence of the interaction between rod-shaped particles, that the torque between two MCC particles in a ...

Microcrystalline Cellulose Modified Waterborne Polyurethane

Materials Performance, 2012
Waterborne polyurethane (WPUR) was synthesized. Micro crystalline cellulose was used to prepare a series of modified WPUR. The mechanical properties of modified WPUR films showed higher tensile strength and elongation than the unmodified one. The water resistance of films was also greatly enhanced after modification.
