Abstract:
A stable disinfectant non-aqueous concentrate comprising:a) at least one mono or dialdehyde containing 2 to 11 carbon atoms; b) at least one glycol or polyol containing 2 to 10 carbon atoms; and, c) at least one lithium-based buffer soluble in said concentrate; d) wherein said glycol or polyol are present in a molar ratio of said glycol or polyol to said mono or dialdehyde to sufficiently displace the water of hydration from binding to said mono or dialdehyde in favor of binding to said glycol or polyol, wherein the concentrate contains substantially no free water such that deterioration of the mono or dialdehyde by internal polymerisation is no more than 10 percent over two years at room temperature and wherein said concentrate is maintained at a pH of about 5 or above.
