UIV Chem Mono nano Silver  solution  appearance:white to brown solution (depends to concentration),and all the solution are transparent(except the Mono nano silver solution for gel)!

UIV Chem Mono nano Silver  solution during the production process with nano-silver similar monomer, monomer nano silver can also be directly dispersed in water to obtain. Therefore, The solution does not contain other chemical components, safety, non-toxic, environmental protection, and can be widely used in medical and health and other fields. Broad-spectrum bactericidal with lasting effect. The performance of anti-bacterial, toxic, skin irritation, mucous membrane of the target had been the boost in SGS test.

Procurement suggestions

Mono nano silver solutions (CAS 7440-22-4) for antimicrobial use must specify particle size (typically 10–20nm), concentration (e.g., 10–100 ppm), and stabilizer type (e.g., citrate) to ensure efficacy and safety. Supplier documentation should include TEM images, zeta potential data, and ISO 22196/JIS Z 2801 test reports against E. coli or S. aureus. Avoid products with undisclosed additives or unstable aggregation. Applications span wound dressings, textiles, or surface coatings—but verify regulatory status: in the EU, nano silver may be classified as a biocide (BPR); in the US, EPA or FDA oversight may apply. Storage in amber glass away from light preserves colloidal stability. Prioritize suppliers with GMP-like controls and clear safety data sheets to mitigate toxicity or environmental risks.
