The aim of this study was to develop sustained-release matrix tablets by means of injection moulding and to evaluate the influence of process temperature, matrix composition (EC and HPMC concentration) and viscosity grade of ethylcellulose (EC) and hydroxypropylmethylcellulose (HPMC) on
International journal of pharmaceutics, 408(1-2), 1-8 (2010-11-26)
The object of this study was to investigate the influence of static and dynamic forces on mechanical properties of the biocompatible polymer ethyl cellulose. Similar polymeric films containing 40% (w/w) of the plasticizer dibutyl sebacate were subjected to tensile forces

A novel perstraction system using liquid-core microcapsules for pesticide and herbicide removal from aqueous environments is proposed. The microcapsules contain an oil, dibutyl sebacate, surrounded by a hydrogel membrane. The extraction efficiency of the capsules was demonstrated with atrazine, methylparathion
