Ethyl Tosylamide

Other names: ethyl-p-toluene sulfonamide

Harm score: 4 (Slightly harmful chemistry)

Ethyl Tosylamide, also known as ethyl-p-toluene sulfonamide, is an organic compound with the formula CH3C6H4SO2N(C2H5)2. Chemically, it is a derivative of sulfonamide. Ethyl Tosylamide is a white powder that is soluble in water, alcohol and ether. This substance is primarily used in the cosmetic industry, especially in the manufacture of nail polishes, to improve the adhesion of the nail polish to the nail and to prolong its life.

However, there is a certain controversy associated with the threatening use of Ethyl Tosylamide. Ethyl Tosylamide can be absorbed through the nails into the body and some studies suggest that it can cause allergic reactions. For this reason, its use in cosmetic products is restricted in some countries. For example, the European Union banned its use in cosmetics as early as 2004. In other parts of the world, however, Ethyl Tosylamide is still commonly found in some cosmetic products. Although it is safe in most cases, it is important to consider the potential risks. Although most people show no reaction to Ethyl Tosylamide, more sensitive individuals may experience irritation or allergic reactions.
