Polymer inhibitor
WebThe optimal approach to polymer control in a styrene unit is to use a combination of inhibitor and retarder. This ensures polymer control during both normal operations and emergency shutdowns. During normal plant operations, a faster reacting true inhibitor provides superior polymer control versus a retarder such as DNBP. In fact, the faster ... The aim of this investigation was to formulate, characterize and evaluate etoricoxib (ET) loaded polymeric nanoparticles for topical delivery. For nanoprecipitation method, ethyl cellulose (EC) was used as polymers. All the formulations were prepared by varying the drug and polymer concentrations. The obtained nanoparticles were evaluated …
