Patent ID: 7622434

Claim:
A gel composition comprising: (a) a sodium hypochlorite solution that is not prepared by the partial electrolysis of a sodium chloride solution; (b) at least one viscosity-enhancing agent chosen from magnesium aluminum silicates, smectite clays, allophone, kaolinite, nacarite, halloysites, sodium montmorillonite, calcium montmorillonite, sauconite, vermiculite, nontronite, saponite, hectorite, bentonite, attapulgite, sepiolite, palygorskite, and mixtures thereof; and (c) at least one electrolyte chosen from USP sodium chloride, USP citric acid, and NF hydrochloric acid, wherein the gel composition has a pH value ranging from about 10.4 to about 11; wherein the sodium hypochlorite is present in the gel composition in an amount ranging from about 0.0125% to about 1% by weight with respect to the total weight of the gel composition; wherein the at least one viscosity-enhancing agent is present in the composition in an amount ranging from about 0.1 to about 10% by weight relative to the total weight of the composition; and wherein the at least one electrolyte is present in the composition in an amount ranging from about 0.01 to about 10% by weight relative to the total weight of the composition.
