Inorganic nanoparticles (NPs) of barium sulphate (BaSO4) were synthesized using the microemulsion route with various cosurfactants. Polyethylene glycol (PEG) was used along with cosurfactants methanol, propanol and hexanol to improve the solubility of polar compounds in non-polar compounds. The addition of alcohols from long carbon chain to small carbon chain increased the rate of intermicillar exchange and decreased the particle size. X-Ray diffraction (XRD) confirms the crystallite size range around 15-20 nm spherical morphology of the particles was observed using Scanning Electron Microscopy (SEM). The symmetrical vibration of SO4 -2 was confirmed by Fourier Transform Infrared (FTIR) at 1079 cm-1 and it stays same for all cosurfactants. Absorption was between 200-400 nm with a large band gap as confirmed by Ultraviolet-Visible (UV-Vis) Spectroscopy..
