Our company are a developer and the producer of a new form of silver - nanoparticles of metal silver in the nulvalentny Ag0 form, without the found amounts of impurity silver in a cationic form (salts, complexes, oxides, akvakationa, clusters, etc.).
Nanoparticles are synthesized on the unique patent technology which does not have analogs in the world. Average diameter of particles in a product of 4 - 12 nanometers, thus, all silver belongs to nanorange, i.e. this product belongs to nanoproducts.
Bezionny, metal silver, owing to absence in its composition of impurity of toxic cationic silver (the II group of danger), is nontoxical and safe (when drawing on skin - to the 4th class of low-dangerous substances according to classification of GOST 12.1.007-76). Since concentration of 1,87 mkg/ml and below, nanoparticles have no toxic effect on culture and do not damage animal cages. At the same time, at the expense of the small diameter, narrow distribution by the sizes, such nanoparticles have own biocidal and virulitsidny effect, comparable with modern antibiotics.
According to results of researches of concentration of Ag0 5-0,1 ppmproyavlyayut bactericidal action, concentration of 0,05 ppm-bakteriostatichesky.
Nanodispersion possesses high sedimentatsionny stability, to influence of light, long resistance to influence of salts (NaCl, phosphates, carbonates, etc.).
Now we arranged industrial production of nanodispersion "A concentrate of colloidal KND-S-K silver Cosmetic raw materials". Concentration of active metal as a part of KND-S-K substance (a liquid form - to 1% 10 000 mkg/ml, powders - to 20%). This dispersion is delivered to various producers as cosmetic raw materials for production of various production of perfumery and cosmetic and medical appointment.
New nanodispersions can be used for preservation and disinfection of water and drinks, especially in the conditions of emergency situations, or for ensuring their long storage (for example, instead of sulfate of the silver used for preservation of water of space stations, submarines, etc.).
