Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 111 words
A cleaning and disinfecting composition comprising (a) an effective amount of at least one interhalogen selected from the group consisting of iodine chloride, iodide trichloride, iodine bromide, bromine chloride or mixtures thereof and (b) an amount of at least one acid which is not appreciably oxidized by the interhalogen selected from the group consisting of nitric acid, phosphoric acid, hydrochloric acid, sulphamic acid, sulphuric acid or mixtures thereof, effective to achieve cleaning and disinfecting, the interhalogen being present in an amount ranging from about 2 percent to about 25 percent, by weight, and the acid being present in an amount ranging from about 75 percent to about 95 percent, by weight.
Claim 2
Dependent Claim 111 words
A cleaning and disinfecting composition comprising (a) an effective amount of at least one interhalogen selected from the group consisting of iodine chloride, iodide trichloride, iodine bromide, bromine chloride or mixtures thereof and (b) an amount of at least one acid which is not appreciably oxidized by the interhalogen selected from the group consisting of nitric acid, phosphoric acid, hydrochloric acid, sulphamic acid, sulphuric acid or mixtures thereof, effective to achieve cleaning and disinfecting, the interhalogen being present in an amount ranging from about 2 percent to about 25 percent, by weight, and the acid being present in an amount ranging from about 75 percent to about 95 percent, by weight.
