Role of plasticizer in membrane coated extended release oral
DBS is frequently used as a plasticizer for ethyl cellulose, and Eudragits based formulations due to their high compatibilities. Moreover, due to its highly hydrophobic nature, it helps to reduce the vapor transmission into the formulation upon storage while retaining the mechanical properties and drug release properties of the formulations
Dibutyl sebacate
Dibutyl sebacate ( DBS) is an organic chemical, a di butyl ester of sebacic acid. Its main use is as a plasticizer in production of plastics, namely cellulose acetate butyrate, cellulose acetate propionate, ethyl cellulose, polyvinyl butyral, polyvinyl chloride, polystyrene, and many synthetic rubbers (especially nitrile rubber and neoprene

Plasticizer Dibutyl Sebacate DBS with Best Quality - Hisea Chem
Uses The product DBS is used as the plasticizer for solid propellants and Their cladding layers, and also as the cold-resistant plasticizer For other polymers. Package It's packed in the closed metal bucket of 200 liters, Net weight 180 kg/drum.
Investigation of Plasticizer Selection for Extended Release
To further understand plasticizer effects and to determine effective plasticizer levels, thermal analysis was conducted on cast lms. A sample of ETHOCEL HP was dissolved in toluene: ethanol (80/20 w/w) solvent mixture at 10% w/w. Plasticizer combinations of OA:DBS at 50:50 or 75:25 ratio were added to the solvent
