Crude glycerin which was obtained during the production of biodiesel with 50 LBP production unit from pongamia seeds was analysed for the free fatty acid, viscosity, pH, color, odour and density and were found that 1.82 %, 118 csts, 8.0, dark brown, unpleasant and 1.5g/cm3 respectively. The crude glycerin was treated with lye for the preparation of soap with different concentrations. The combination of glycerin (1000ml), water (100ml), sodium hydroxide lye (50g) and raw caustic soda (10g) and lemon juice (50ml) was shown better result with respect to removing of stains, household utensils and oil equipments and pH was in the usability range of 8.0
