Abstract

An aqueous disinfecting solution, a concentrated version of the solution, and a dry powdered composition which may be dissolved in water to provide the solution. The solution has a pH of from 0.6 to 7 and comprises (a) hydrogen peroxide in a concentration of from 0.01 to 6% w/w; and (b) at least one component chosen from cyclic carboxylic acids and aromatic alcohols, in a concentration of from 0.01 to 10% w/w, all based on the total weight of the solution. The cyclic carboxylic acids are preferably 2-furan carboxylic acid, benzoic acid and salicylic acid and the aromatic alcohol is preferably benzyl alcohol. Furthermore, the solution may contain surfactants, corrosion inhibitors, hydrotropes, cation sequestering agents, hydrogen peroxide stabilizers, solvents, thickeners, skin conditioning agents, antifoams, and pH buffers.
