Sodium thioglycolate (CAS 367-51-1), also known as sodium mercaptoacetate or thioglycolic acid sodium salt, is a white crystalline powder used in depilatory cosmetics, perm solutions, rubber processing, and as the STG flotation depressant for copper-molybdenum separation.
Potassium hydroxide (chemical formula KOH), commonly called caustic potash or potash lye, is an inorganic alkali metal hydroxide and one of the strongest bases used in industry. It appears as a white, odorless solid — typically in pellet, flake, or powder form — and dissolves readily in water with a strong exothermic (heat-releasing) reaction.
