Cupron Technology has been multiple-independently tested in laboratory settings against generally accepted clinical test protocols, utilizing standard Good Laboratory Practices (GLP) test conditions. Specific test results are maintained on file and available upon a qualified request.
In addition to specific safety testing performed on Cupron Technology, the risk of dermal sensitivity to copper is considered extremely minimal. Furthermore, longstanding commercial use of personal care products validates the laboratory results described above. That copper is considered safe to humans. Note the widespread (millions of women) and prolonged (more than 10 years by a single individual) use by women of copper internal medical devices (1) and over-the-counter wound healing treatments containing copper (2).
