Biocidal aldehyde composition

Abstract

A novel combination of a biocide (Glutaraldehyde), a surfactant (BAK), in an alcohol/water solution, plus functional excipients. The Glutaraldehyde and BAK are combined in specific concentrations in an alcohol-solution form, with the other functional excipients specifically for the intended application. An embodiment for the oil and gas recovery industry is described in which the excipients Glutaraldehyde and cidal agent and BAK surfactant synergistically improve oil recovery. An embodiment for the in the healthcare industry (e.g., medical instrument sterilization) is described in the form of an immersion solution, spray, or pre-moistened cleaning wipette, with excipients including Trienthanol Amine, Glycol Ether, and Sulfonic Acid and water. In both cases the Glutaraldehyde in combination with the BAK works in synergy to kill bacteria and especially SRBs more effectively. The foregoing constituents are combined in preferred concentrations within acceptable ranges to provide a synergistic neoteric formulation that combines biocidal molecules in a biological chemical system that actively transports itself into the cells, through biofilm and cell wall/membranes, thereby overcoming penetration restraints to improve kill and kill time, without the need for activation or any time or temperature control. This is an effective example of synergistic complementarity.
