Description
Summary:This paper describes the determination of the glass transition temperature and the amorphicity of some natural gums. These two parameters are very important in pharmaceutical material science. Standard instrumental procedures were used in the determination. Results obtained were used to further characterize these functional polysaccharides that have been investigated in the formulation of some dosage forms, without to date adequately describing their thermal and crystal properties. Knowledge of the thermal and crystal properties will widen the horizon of usage of these emerging functional pharmaceutical excipients.
