The glycerin obtained from the biodiesel production was purified by fractioned distillation at reduced pressure, where it was achieved a product superior to the norms ASTM D1257-07 for industrial glycerin. Crude glycerin was tested as raw material for the production of solid soap, using 40 g of NaOH, diluted in 250 mL of water, for each liter of methanol free glycerin, at 60 – 70 ^oC. The soap was reformulated as paste soap, and liquid soap. Laboratory analysis demonstrated that paste and liquid soaps presented similar properties to several commercial soaps, with the advantage that they improve the skin conditions after they were used. The lubricant and moisture properties of the crude glycerin were also used, testing it in the cure and mold stripping of concrete structures. The stripping was made with some technical and environmental advantages, as it was compared with other products, as used motor oils. Its use as curer showed that it increased the resistance of the structures where it was applied. It is concluded that these applications of crude glycerin offer a value-added to this byproduct, making more profitable the biodiesel production.
