Copper pyrithione (CPT) is an antifungal and antibacterial agent. It can make it through two processes, namely water extraction and ethylene glycol extraction.

It is produced by reacting copper hydroxide with a 2,4-pyridine dicarboxylic acid in the presence of sulfuric acid.

The former involves the treatment of copper sulfate with sodium hydrosulfite, while the latter requires the treatment of pyridine with ethylene oxide followed by acidification of its solution.

It is a light blue-colored compound that is soluble in organic solvents and water.  It is an antifungal agent that interacts with sebum, an oily substance secreted by the skin to lubricate and protect the skin and hair.


Copper pyrithione, also known as CPT, is antifungal and antibacterial agent. It is often used to treat skin conditions such as dandruff.

It works by inhibiting squalene peroxidation of hair follicles by inhibiting the fungus that causes this condition. Some products combine copper pyrithione with other dandruff-fighting ingredients, such as ketoconazole.

It is also used in sunscreens, cosmetics, paints, polishes, and lubricants. It is used as an anti-caking agent in the food industry.

It is also used in marine antifouling paints to prevent aquatic organisms such as crustaceans and algae from adhering to hull plates.
