TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: In the composition (C1), the nanoparticles of bentonite powders intercalated with the metal ions contain ions of Ag+, Zn2+, Cu2+, where the ratio by weight of nanoparticles intercalated by ions of Ag+:Zn2+:Cu2+ is 1:(0.2-0.8):(0.2-0.5); the nanoparticles of bentonite powders, intercalated with the metal ions, contain only ions of Ag+ and Zn2+ in the ratio by weight between them of nanoparticles intercalated by ions of Ag+:Zn2+ is 1:(0.2-0.8); the nanoparticles of bentonite powders, intercalated with the metal ions, contains only ions of Zn2+ and Cu2+ in ratio by weight between them: nanoparticles intercalated by ions of Zn2+:Cu2+ is 1:(0.2-0.5); and the dispersed nanoparticles of bentonite powders have mainly dimensions up to 70 nm. The composition (C1) is in liquid form containing the nanoparticles of bentonite powders intercalated by Zn2+ ions and by at least one ion selected from Ag+ and Cu2+, compounded with a polar solvent in a ratio nanoparticles of bentonite:polar solvent as 1:20. Preferred Process: In the process, the fractions of bentonite powder obtained at the end of the stages (b), (c), (d) are dispersed in such a way that nanoparticles of bentonite with dimensions of not greater than 70 nm are obtained, and then are compounded among them; the fractions of bentonite powder obtained at the end of the stages (b), (c), (d) are first compounded among them and then dispersed in such a way that nanoparticles of bentonite with dimensions of not greater than 70 nm are obtained; the dispersion of the bentonite powders, up to nanoparticles with dimensions mainly not superior to 70 nm, is performed by repeated intensive mixing in a plenty of water and successive decanting, drying and grinding in a suitable mill; and the dispersion of the bentonite powders, up to nanoparticles with dimensions of not greater than 70 nm is performed by mixing the powder with deionized water in a ratio 1:10 and then applying an ultrasonic dispersant.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The polar solvent is water; or is a 40% hydro-alcoholic solution. ACTIVITY - Fungicide; Antibacterial; Dermatological; Antiulcer; Vulnerary. An efficacy of composition comprising silver (Ag+), copper (Cu2+), zinc (Zn2+) ions and water, was evaluated for antibacterial activity, on Staphylococcus aureus, in terms of diameter of zone of a growth inhibition of microorganism around of standard disk having diameter of 5 mm. A composition containing copper ion and water was used as control. The test/control showed diameter of zone of a growth inhibition of microorganism of 19/14 mm, respectively.    MECHANISM OF ACTION - None given.    EXAMPLE - A semifinished product was cleaned from acid anions, dried up and modified by 10-20% water solution of silver nitrate (at red illumination). It was apply to 15% water solution of silver nitrate. The process of modification was carried out at its keeping in the specified solution and at a temperature corresponding to its solubility in water. The obtained modified semi-finished product was repeatedly washed out for removal of sodium salts, filtered and dried at 200-800 degrees C. The consumption of water solutions for the treatment semi-finished product (5 g) was bentonite:water solution as 1:20. After drying, a bentonite powder (4.8 g) without salts of sodium and intercalated by ions of silver (Ag+) was obtained.
