FORMULATION AND CHARACTERIZATION OF LAKE COLOR OBTAINED FROM BLACK CARROT
AbstractColorants are mainly used to impart a distinctive appearance to the pharmaceutical dosage forms. The present study was carried out to develop aluminium lake color of a dye obtained from black carrot using different adsorbents (Aluminium oxide or aluminium hydroxide) in different ratio by simply mixing them to get dye adsorbed onto the surface of adsorbent. Adsorption experiment was carried out for 60 minutes. Aluminium oxide at a concentration level of 30% w/v found to be the choice of adsorbent after optimization because maximum adsorption of dye from reaction mixture after 60 minutes and maximum % yield. After optimization of adsorbent the effect of pH and temperature also studied by formulating lake by varying these two parameters. It was observed that a higher temperature (50oC) and a lower pH (3) favor the adsorption. The lake then characterized for various physicochemical properties like angle of repose, Carr’s index, hausner’s ratio, loss on drying, particle size and limit test for heavy metals. The lake was found to follow pseudo second order kinetics
