ABSTRACT OF THE DISCLOSURE There is disclosed, in one aspect, a process for disinfecting a substrate. This process comprises contacting the substrate with a composition comprising a chlorine-dioxide liberating compound, such as sodium chlorite, with sufficient organic acid other than lactic acid to lower the pH of the composition to less than about 7. The organic acid has the formula Image (I) R' and R2 may be the same or different and may be selected from the group consisting of hydrogen, methyl, -CH2COOH, -CH2OH, -CHOHCOOH, and -CH2C6H5. The pK of the organic acid is from about 2.8 to about 4.2. In another aspect, the present invention provides a synergistic composition for disinfecting a substrate. This composition comprises the chlorine dioxide liberating compound and organic acid discussed hereinabove as well as a vicinal polyhydroxy compound such as glycerin. In yet another aspect, there is disclosed a process for disinfecting a substrate using this synergistic composition.
