Carbopol is crosslinked acrylic acid. Carbopol can be used in developing formulations for transdermal, oral, rectal use. It is forms strong gel in low concentration. Therefore, it can be used in low concentration in developing controlled release formulations. This increases the cost effectiveness and number of formulation options. In spite of its effectiveness, carbopol is one of the most efficient however underutilized polymer in oral controlled drug delivery system development. This is attributed to the difficulty in processing the carbopol. Carbopol has poor flow characteristics and stickiness. Objective of our research is to eliminate processing difficulties of carbopol using hot …
