Wet Granulation Process : Pharmaceutical Guidelines

Wet granulation involves the massing of a mix of dry primary powder particles using a granulating fluid.The fluid contains a solvent which can be removed by drying, and should be non-toxic.Typical solvents include water, ethanol and isopropanol and methylene chloride either alone or in combination. The granulation liquid may be used alone or, more usually, as a solvent containing a dissolved ...

Granulation techniques and technologies: recent progresses

Feb 18, 2015· Introduction. Granulation, a technique of particle enlargement by agglomeration, is one of the most significant unit operations in the production of pharmaceutical dosage forms, mostly tablets and capsules. 1 During the granulation process, small fine or coarse particles are converted into large agglomerates called granules. Generally, granulation commences after initial dry mixing of the ...

Part One Sol Gel Chemistry and Methods

The easy agglomeration or aggregation of fine particles (sol particles) is caused by attractive van der Waals forces and/or minimization of the total surface or interfacial energy of the system. In order to prevent aggregation (i.e., to stabilize the sols), repulsive forces of comparable dimensions are required that must be overcome during ...
