SCCS/1596/18 Final Opinion on Colloidal Silver (nano) __________________________________________________________________________________________ 3.1.1.6. Empirical formula Ag Ag0 H2O 3.1.2. Physical form Colloidal silver is described as water dispersion (colloid) of silver nanoparticles; it is a clear liquid with no odour. The following product specifications of the various forms of colloidal silver have been reported (Table 2): Table 2: Product specifications as provided by the Applicants Dispersions A B D J K L C E H I Concentration 100±10 ppm (mg/kg) 50 ppm (mg/kg) max 0.015 % silver Particle size (% of the total amount) Surface Area m2/g 1 m2/cm3 (VSSA) Surface charge (Zeta potential) REFs 1,3,4, 5,7,10, 11,43, 48,55 8 22 25,55 3-5 nm (80-85%) 5-100nm(15-20%) (BET) 1 2-5 nm (70-75%) 5-100nm(25-30%) 39 nm -41.6 (± F G 1000 ppm Lowest cut-off 1.56 nm Number weighted median 5.79 nm 192 m2/g (BET) 50 mV 16,17 10) mV *Colloidal silver dispersions A, B, C, D, J, K, L are the same dispersions submitted by seven different Applicants. Also dispersions F and G seem to be similar (same name and specifications). SCCS comment: Information on concentration in terms of both particle mass and particle number per volume must be provided for dispersions and per mass for dry powders. The content of ionic silver should also be provided for each material when dispersed in aqueous media. The data provided for surface area and VSSA for dispersions A, B, C, D, J, K and L do not seem to be correct. The large differences in surface charge for dispersions F, G and I need to be explained. 3.1.3. Molecular weight Molecular weight of silver: 107.87 g/moles 9 Ref.:13, 15
