Mar 17，2023

Copper pyrithione is Pyridinethione derivative, and it 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. Copper pyrithione is effective biocide used to control algae, fungi and bacteria. It is used in anti microbial formulation for antifouling paints and as biocide and preservator for textiles, rubber, leather and fiber.

Preparation

A process of preparing a composition containing particles of copper pyrithione comprising:

reacting zinc pyrithione with a copper salt in the presence of a non-reactive polymer or non-polymer binder,

wherein from greater than 20 wt % to 90 wt % of the copper pyrithione particles have a particle size of greater than 10 microns as determined by laser light scattering using a particle size distribution analyzer.

First aid measures

First-aid measures general:Never give anything by mouth to an unconscious person. Do not induce vomiting. If you feel unwell, seek medical advice (show the label where possible).

First-aid measures after inhalation : Allow breathing of fresh air. Allow the victim to rest. If you feel unwell, seek medical attention.
