Abstract: Compositions having antimicrobial activity contain surface functionalized particles comprising an inorganic copper salt which has low water solubility. These types of inorganic salts may also be introduced in porous particles to yield antimicrobial compositions. The compositions may optionally comprise additional antimicrobial agents, salts with high water solubility, organic acids, salts of organic acids and their esters. The compositions may be added to various fluids used in the petroleum extraction industry, or used as coatings on components used in this industry. These antimicrobial materials may be used for reducing both anaerobic and aerobic bacteria and are also useful for reducing corrosion of ferrous components caused by anaerobic bacteria. Although such compositions may be used for any antimicrobial application, and some of the other important uses of these compositions are in wound care, personal care and waste processing.

Abstract: Compositions having antimicrobial activity contain particles comprising at least one inorganic copper salt; and at least one functionalizing agent in contact with the particles, the functionalizing agent stabilizing the particle in a carrier such that an antimicrobially effective amount of ions are released into the environment of a microbe. The average size of the particles ranges from about 1000 nm to about 3 nm. Preferred copper salts include copper iodide, copper bromide and copper chloride, most preferred being copper iodide. Preferred functionalizing agents comprise materials with a molecular weight of 60 or above, which include amino acids, other acidic materials, thiols, hydrophilic polymers, emulsions of hydrophobic polymers and surfactants. The functionalized particles are preferably made by a grinding process.
