Hypochlorite denture compositions and methods of use
First Claim
1. A method for cleaning dentures, said method comprising:
- contacting said dentures with a solid, one-layered composition in water, wherein said composition comprises;
a) a hypochlorite selected from the group consisting of calcium hypochlorite, magnesium hypochlorite and mixtures thereof;
b) a builder selected from the group consisting of carbonate, bicarbonate, sesquicarbonate and mixtures thereof;
c) at least 30% by weight of an acid selected from the group consisting of a carboxylic acid, a dicarboxylic acid, a sulfonic acid, an acid sulfate, an acid phosphate, and mixtures thereof;
d) a water-soluble polymer selected from the group consisting of a polycarboxylate, a sulfonated carboxylate, a polysulfonate, a polyvinylpyrrolidone, a polypyridinium salt, a polyquaternary ammonium salt, and mixtures thereof;
e) at least one anionic surfactant; and
f) at least one hydrotrope;
g) wherein the composition does not contain potassium hypochlorite, sodium hypochlorite, lithium hypochlorite, N-halogenated compounds, peroxides, persulfates, hydantoins, isocyanurates, carboxylic acids that also have hydroxyl, amino, amido, imino, or imido groups;
h) wherein the composition contains only one layer.

Abstract
A solid composition including calcium and/or magnesium hypochlorite, a builder (e.g., one or more of carbonate, bicarbonate, sesquicarbonate), an acid, a water-soluble polymer, at least one anionic surfactant, and optionally, a hydrotrope. The composition does not include any potassium hypochlorite, sodium hypochlorite, lithium hypochlorite, N-halogenated compounds, peroxides, persulfates, hydantoins, isocyanurates, or carboxylic acids that also have hydroxyl, amino, amido, imino, or imido groups. Upon dissolution of the composition in water, the calcium and/or magnesium hypochlorite and acid react to form hypochlorous acid. The use of hypochlorous acid, rather than direct use of an alkaline or alkaline earth hypochlorite results in a composition that is typically acidic rather than basic, and that results in improved cleaning. The composition is particularly suited for cleaning and disinfecting dentures.
