Is Silicified Wet-Granulated Microcrystalline Cellulose Better than Original Wet-Granulated Microcrystalline Cellulose?

Pharmaceutical Development and Technology, 1999
The purpose of this study was to investigate the effect of granulating water level on the physical-mechanical properties of microcrystalline cellulose (MCC) and silicified microcrystalline cellulose (SMCC). Granulations containing either MCC or SMCC were manufactured at different water levels using a high-shear mixer and were then tray-dried. The water

Fourier transform infrared spectroscopy analysis for hydrothermal transformation of microcrystalline cellulose on montmorillonite

Applied Clay Science, 2014
Specifying the interactions between montmorillonite and cellulose is helpful for understanding the evolution of biomass in soil and the geological formation of fossil fuels in nature.

Microcrystalline cellulose in tableting

Journal of Pharmaceutical Sciences, 1966
The development of microcrystalline cellulose has made available to the pharmaceutical industry an extremely valuable tableting agent. It was found that tablets of plain microcrystalline cellulose will tend to soften and swell when exposed to humid conditions, but the effect is reversed upon the removal of increased humidities.

Coagulation of microcrystalline cellulose dispersions

Journal of Colloid and Interface Science, 1969
Abstract The coagulation effects on microcrystalline cellulose sols of simple ions, hydrolyzed metal ions, chelate complexes, and a series of alkylammonium chlorides differing in length of the hydrocarbon chain have been investigated. It was found that these sols are much more sensitive towards electrolytes than typical lyophilic colloids.

MICROCRYSTALLINE CELLULOSE STABILIZEDEMULSIONS

Journal of Dispersion Science and Technology, 1986
ABSTRACT Miorocrystalline cellulose stabilized emulsions (o/w) were evaluated by means of brightfield and polarized light microscopy, freeze-etch electron microscopy, droplet size analyses and rheologic measurements. These studies indicated that miorocrystalline cellulose (Avicel RC591 ) forms a network around emulsified oil droplets.

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.

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 ...

Adsorption of cationic amylopectin on microcrystalline cellulose

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1993
Abstract The effects of electrolyte concentration and pH on the adsorption of cationic amylopectin on microcrystalline cellulose were investigated. The adsorbed amount in the pseudo-plateau of the isotherm showed a maximum as a function of the electrolyte concentration. We compared the data with a recent theory on polyelectrolyte adsorption.

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.

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 ...
