What it is used for and where

Industry

It is a  bicyclic heterocyclic system corrosion inhibitor for copper and alloys, silver, cobalt, aluminum and zinc.

It demonstrated higher thermal stability than 1,2,3-triazole and is advantageous in many near-neutral solutions and not appreciably mineralised by UV irradiation.

Used in:

• antifreeze fluids, aircraft de-icing
• metal cleaning
• copper antioxidant
• corrosion protection
• machine dishwashing detergents for silver protection 

Cosmetics

Antimicrobial agent. This ingredient is able to suppress or inhibit the growth and replication of a broad spectrum of microorganisms such as bacteria, fungi and viruses by making the stratum corneum temporarily bactericidal and fungicidal.
