talc
talc powder is one of the most widely used minerals in the world that is extracted from the mine and is a soft and white mineral substance. This powder is used in cosmetic, medical, pharmaceutical, food industries as well as plastic and electronic industries. Talc absorbs moisture and keeps the skin free of any fat and makes the skin soft and supple. Also, due to the presence of many minerals, it prevents skin complications such as hives, and for this reason, it is used in baby powder. As mentioned, talcum powder is also used in cosmetic industries
But what is the reason? The pigments used in cosmetics are so thick that they cannot be used directly without a diluent, so the main choice of cosmetic companies as a diluent is talcum powder.
