In this experiment it will be possible to prepare deodorant and antiseptic foot powder, perform crushing and screening techniques, understand what the eutectic mixture is and how to correct it and learn how to perform geometric dilution.

Mix 5% camphor and 1% menthol in a porcelain grate. Next, add zinc oxide (6%), grinding well. For the formulation to begin to solidify, add the vehicle (Talc), following the geometric dilution technique (proportions above 1:10). Finally, sift the final mixture with small sieves (ASTM 40), using baking paper. Fill the pharmaceutical preparation into the bottle you brought to practice.
