The invention relates to a process for reducing the minimum inhibitory concentration (MIC) of a biocide against at least one strain of bacteria and/or at least one strain of yeast and/or at least one strain of mould in an aqueous preparation. The invention further relates to the use of a water soluble source of lithium ions for reducing the minimum inhibitory concentration (MIC) of a biocide against at least one strain of bacteria and/or at least one strain of yeast and/or at least one strain of mould in an aqueous preparation.

Disclosed are compositions comprising a) an antimicrobial agent, which is selected from the group consisting of biocides containing halogen atoms and/or containing phenolic moieties, formic acid, chlorine dioxide, chlorine dioxide generating compounds, dialdehydes; components containing an antimicrobial metal such as antimicrobial silver, and b) a polyamine, especially a polyethylenimine. The polyamine is effective as a booster for the antimicrobial agent.

An antimicrobial abrasive article comprising a nonwoven substrate material impregnated with a first and second formulation. The first and second formulations have persistent residual antimicrobial effectiveness against one or more microbial organisms. The first and second formulations include one or more antimicrobial agents and abrasive particles uniformly dispersed in a polymer composition. The first and second antimicrobial agents can be the same or different. The polymer compositions can be the same or different.

A process is described for stabilizing an aqueous preparation against microbial growth. Also described, is the aqueous preparation stabilized against microbial growth as well as the use of a source of at least one metal oxide and/or its hydrated form for reducing the amount of an antimicrobial agent against at least one strain of bacteria and/or at least one strain of yeast and/or at least one strain of mold in an aqueous preparation. The use of a composition including at least one antimicrobial agent and a source of at least one metal oxide and/or its hydrated form as an antimicrobial composition in an aqueous preparation, is also described. In addition, the use of magnesium oxide, magnesium hydroxide, calcium oxide, calcium hydroxide, half burnt dolomite, burnt dolomite, beryllium oxide, beryllium hydroxide, strontium oxide, strontium hydroxide, barium oxide, barium hydroxide, and mixtures thereof for increasing the pH of an aqueous preparation to a pH of above 8 and the use of an aqueous preparation stabilized against microbial growth in paper, plastics, polymer compositions, paint, coatings, concrete and/or agriculture applications are described.
