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.

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.

Functional performance of silicified microcrystalline cellulose versus microcrystalline cellulose: a case study

Drug Development and Industrial Pharmacy, 2009
During the development of a tablet dosage form of an investigational compound, R411, several aspects were identified as critical quality attributes that required optimization. The use of nonsolvent processing prevented the moisture-induced physical changes in the drug product but presented manufacturing challenges related to sticking during compression

The mechanical properties of compacts of microcrystalline cellulose and silicified microcrystalline cellulose

International Journal of Pharmaceutics, 2000
The mechanical properties of compacts of unlubricated microcrystalline cellulose and silicified microcrystalline cellulose were evaluated using the diametric tensile test. The results suggested that, under comparable testing conditions, compacts of silicified microcrystalline cellulose exhibited greater strength than those of microcrystalline cellulose.

Adsorption of an Amine Drug onto Microcrystalline Cellulose and Silicified Microcrystalline Cellulose Samples

Drug Development and Industrial Pharmacy, 2003
The adsorption of a model amine drug (tacrine hydrochloride) from aqueous solution onto 21 microcrystalline cellulose (MCC) based samples has been investigated. The MCC source (manufacturer) affected adsorption. The adsorption appeared to be fully reversible.

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

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.
