Abstract: The present study was undertaken for the analytical characterization of Carbopol polymer (Carbopol 940 and Carbopol 934). Purity and the crystalline or amorphous nature of two grades of polymer were evaluated. Fourier Transform Infrared (FTIR) analysis was performed by FTIR Spectrophotometer interfaced with infrared (IR) microscope operated in reflectance mode. The spectra were collected over the wave number from 400 to 4000 cm-1 at room temperature. Raman spectroscopic analysis for the two grades of polymer was performed by a low resolution potable Raman Spectrometer (Raman system R-3000), using 785 nm solid state diode laser, with fibre optic sampling probe. The Raman spectra were collected over the wave number from 140 to 2500 cm-1 at room temperature. X-ray powder diffraction (XRD) data for Carbopol polymer were obtained using a powder diffractometer. The two grades of polymer were scanned from a Bragg angle 2θ between 100 and 700. The obtained data were tabulated in terms of th...
