摘要:A composition and method for inducing and inflicting damage to cell membranes of microorganism by inducing changes in membrane permeability caused by polycation-induced membrane pores. The control of Clostridium difficile spores with an efficacy of 99.99% on hard surfaces is provided. The invention includes the application of an evaporation-induced self-assembly, surfactant-mediated synthesis or self-condensing polymer, which forms a film which is both flexible on the surface as a nano-polymeric coating and with refractive index yielding a transparent coating. The polymeric matrix includes various biocidal polymeric cationic quaternary salts, one being a silyl quaternary having a kinetic zeta potential to disrupt bacterial spores functions. The polymeric matrix consist of multiple small molecule biocides as well as polymerics biocide combinations not otherwise seen to develop an surface topography of peaks and troughs in the nano range to resist bacterial adhesion factors and subsequent biofilm formation. The surfactants induce self-assembly film topography.

摘要:Wood preservative systems comprising (a) a biocidal effective amount of (i) at least one di C8-C12 alkyl quaternary ammonium carboxylate having the formula wherein R1 and R2 are a C8-Cl2 alkyl group; R3 is a substituted or unsubstituted, interrupted or uninterrupted C1-C100 group; l and q independently are 1, 2 or 3 and (l) (q) is 1, 2, or 3; and n is 0 or an integer from 1 to 50; (ii) at least one di C8-C12 alkyl quaternary ammonium borate having the formula wherein R1 and R2 are defined as above, and a is 2 or 3, but when a is 2, b is 0 or 1, and when a is 3, b is 0, 1, or 2; or (iii) a combination of (i) and (ii); and (b) a solvent are provided. These carboxylate quats as well as carboxylate quats wherein R1 is a C1-C20 alkyl or aryl-substituted alkyl group and R2 is a C8-C20 alkyl group are preferably prepared by an indirect or a direct synthesis. The indirect synthesis includes reacting a corresponding quaternary ammonium carbonate with a carboxylic acid, while the direct synthesis method includes reacting a corresponding quaternary ammonium chloride with a metal carboxylate salt. The metal-free wood preservative systems can be applied to wood substrates.
