FAQ

How does copper ion antibacterial action differ from silver ion?
Copper ions generate reactive oxygen species causing oxidative damage, while silver ions mainly disrupt cell membranes and DNA. Copper offers broader spectrum action in some cases.
Is the copper ion antibacterial agent safe for direct skin contact products?
Yes, it complies with safety standards for skin-contact applications but it is recommended to follow local regulations and do compatibility testing.
Can this agent be used in transparent plastics?
Due to its natural color, it may impart a slight tint; suitability depends on the specific product requirements.
What is the typical shelf life?
Generally 12 to 24 months if stored properly in sealed containers away from moisture.
Are there environmental concerns with copper ions?
Copper is a natural element and biodegradable; however, usage concentrations should comply with environmental regulations.
