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.

Properties

Appearance:Powder

Physical State:Solid

Solubility:Insoluble in water

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. In case of irregular breathing or respiratory arrest provide artificial respiration. Do not apply mouth-to-mouth resuscitation. Induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. 

First-aid measures after skin contact : Remove affected clothing and wash all exposed skin area with mild soap and water, followed by warm water rinse. Immediately flush skin with plenty of water for at least 15 minutes. If skin irritation occurs: Get medical advice/attention. 

First-aid measures after eye contact : Rinse immediately with plenty of water. Remove contact lenses, if present and easy to do. Continue rinsing. Obtain medical attention if pain, blinking or redness persists. First-aid measures after ingestion : Rinse mouth. Do NOT induce vomiting. Obtain emergency medical attention.
