Pyrithione Chemical Properties,Uses,Production
Description
The sodium salt of N-hydroxy-2-pyridinethiones has a germicidal activity againts yeasts and fungi. Sodium omadine is a 40% aqueous solution of sodium pyrithione.
Uses
It is used in the metallurgical industry as a component of water-based metalwork fluids, of aceto-polyvinyl lattices, water-based printer's ink, lubrieant for synthetie fibers and anti-dandruff shampoos. A case was reported in a metallurgie worker.
Definition
ChEBI: A pyridinethione that is pyridine-2(1H)-thione in which the hydrogen attached to the nitrogen is replaced by a hydroxy group. It is a Zn2+ ionophore; the zinc salt is used as an antifungal and antibacterial agent.
