In recent decades, the world's population, especially the West, has begun to suffer the reverse of "technological progress": pollution of soil, air and water with noxious substances, pesticides, heavy metals, etc. This boomerang return is directly proportional to the increase in allergies, food intolerances, autoimmune and neuro-degenerative diseases. It is about aluminum, more precisely the toxicity of some of its forms used in food, medicine and cosmetics. The aim of this project is to inform, raise awareness and popularize the risks of using antiperspirants containing aluminum for human health. After an intense documentation we determined the aluminum content of some antiperspirants using complexometric titration. I also chose some recipes for obtaining deodorants from natural products that I obtained in the chemistry laboratory. Working on this project, I gained a lot of knowledge about the content of deodorants and the health hazards to which we are exposed. At the same time, we made natural deodorants that can successfully replace the commercial ones. Baking soda, starch and coconut oil are among the best known ingredients that fight against the unpleasant odors eliminated by our body. To this combination was added lemon juice and essential oils to create the desired smell. Do we continue to use products that we know nothing about or do we know could hurt us? Or, are we looking for natural, safe alternatives? There are a number of natural deodorants on the market that claim to have 100% safe ingredients. However, it is safest to produce our deodorant at home, from as few ingredients as possible, which we also tried in this project.
