Sodium pyrithione inhibits growth of fungi, yeast, mold and bacteria. Sodium and zinc salt of pyrithione N-oxide are widely used in cosmetics and shampoo. In acidic media, amine N-oxides are cationic and can act as a mild conditioner. They are used in body care products. Pyridinethione derivatives, belong to a class of cyclic sulfur organo products containing sulfur atom (S) and often oxygen (O), nitrogen (N), hydrogen (H), as well as other elements, can find application for making biologically active agents such as antiviral, antibacterial, antifungal agents.
