Abstract
Abstract There is disclosed a cleansing composition, suitable for use as a denture cleansing composition, the cleansing composition comprising: (a) a pre-granulated mixture of an anhydrous perborate, a perborate monohydrate and a polymeric fluorocarbon compound, the ratio of the anhydrous perborate to the pervorate monohydrate being from 0.5:1 to 1.75:1 by weight, and the polymeric fluorocarbon being present in an amount of from 0.05% to 0.85% by weight based on the weight of the pre-granulated mixture; and (b) a monopersulphate compound, present in an amount of from 30% to 65% by weight based on the total weight of the cleansing composition. A process for preparing the cleansing composition is also disclosed. The composition can be tableted on a high speed tableting press and packaged using conventional foil packaging equipment without tablet fracture or chipping.

Claim 1
Independent Claim
97 words
A cleansing composition, suitable for use as a denture cleansing composition, the cleansing composition comprising: (a) a pre-granulated mixture of an anhydrous perborate, a perborate monohydrate and a polymeric fluorocarbon compound, the ratio of the anhydrous perborate to the perborate monohydrate being from 0.5:1 to 1.75:1 by weight, and the polymeric fluorocarbon being present in an amount of from 0.05% to 0.85% by weight based on the weight of the pre-granulated mixture; and (b) a monopersulphate compound, present in an amount of from 30% to 65% by weight based on the total weight of the cleansing composition.
Claim 2
Dependent Claim
97 words
A cleansing composition, suitable for use as a denture cleansing composition, the cleansing composition comprising: (a) a pre-granulated mixture of an anhydrous perborate, a perborate monohydrate and a polymeric fluorocarbon compound, the ratio of the anhydrous perborate to the perborate monohydrate being from 0.5:1 to 1.75:1 by weight, and the polymeric fluorocarbon being present in an amount of from 0.05% to 0.85% by weight based on the weight of the pre-granulated mixture; and (b) a monopersulphate compound, present in an amount of from 30% to 65% by weight based on the total weight of the cleansing composition.
Claim 3
Dependent Claim
32 words
A cleansing composition according to claim 1, further comprising sodium carbonate or calcium carbonate in an amount of from 8% to 10% by weight based on the total weight of the composition.
Claim 4
Dependent Claim
48 words
A cleansing composition according to claim 1 or 2, wherein the monopersulphate compound is an alkali metal monopersulphate, preferably potassium or sodium monopersulphate, or an alkaline earth metal monopersulphate present in an amount of from 40 to 50% by weight based on the total weight of the composition.
Claim 5
Dependent Claim
