대표청구항 ▼

A solid denture cleaning composition comprising a tartar dissolving amount of an acidic component which dissolves to provide an acidic solution when the composition is mixed with water and a neutralising component having a protective coating, in an amount such that, when the composition is mixed with water the protective coating is so affected that the neutralising component is released over a period of time to neutralise the initially acid solution to a pH of more than 5.5. A denture cleaning composition as claimed in claim 1 additionally comprising a bleaching agent selected from the group consisting of a salt of the acid H2SO5, a perborate salt and a percarbonate salt. A solid cleaning composition for dentures comprising a. an acidic component selected from the group consisting of sulphamic acid, acetodiphosphonic acid, citric acid, tartaric acid and sodium bisulphate; b. a sufficient quantity of an acid-neutralising component to neutralise said acidic component selected from the group consisting of a carbonate salt, a bicarbonate salt, a mixture of a carbonate with a bicarbonate salt, and a mixture of bicarbonate salt with a phosphate salt; c. a protective coating around the acid neutralising component comprising a polymer selected from the group consisting of a sytrene/acrylic ester copolymer, a styrene/allyl alcohol copolymer and a vinyl acetate/versatic ester copolymer, the composition being such that, when the composition is added to water the acidic component dissolves to give an acidic solution, and the protective coating formed around the acid-neutralising component so retards the release of the acid-neutralising agent that, for a period of time, the solution remains sufficiently acidic to remove tartar deposits.
