RECOVERY OF ALUMINUM FROM WASTE AND ITS USE IN THE SYNTHESIS OF ALUMINUM AND POTASSIUM ALUM USED IN THE PREPARATION OF ANTIPERSPIRANTS

In this work, with minimal costs and a good yield, aluminum from waste was recovered and transformed into the form of aluminum and potassium alum, a product with very good antiperspirant and antihemorrhagic properties and less aggressive than aluminum chloride, which is widely used in antiperspirant cosmetic products. The chemical method of synthesis used in our research is a simple one based on low energy consumption and the use of cheap resources. The synthesis of aluminum and potassium alum is proven by structural analysis, and the product obtained has been purified to ensure its possibility of use in the cosmetic industry. In the second part of the paper, an attempt to use the alum obtained in the preparation of an antiperspirant with simple and cheap components, as natural as possible, recognized for their beneficial properties on the body, is presented: collagen, as an anti-aging agent, and sodium bicarbonate, respectively borax, known as substances with antibacterial and antifungal action.
