Claims34
A denture cleansing composition in powder form derived from a mixture comprising:
- (a) a pregranulated compressed mixture of an anhydrous perborate in an amount of from about 5% to about 25% by weight of said composition, a perborate monohydrate and a lubricant and compression aid, wherein the weight ratio of anhydrous perborate to said perborate monohydrate in said pregranulated mixture is from about 1:3 to about 1:1 the amount of perborate monhydrate in the premixture being reflected by the ratio;
- and
- (b) a monopersulfate compound in an amount of from about 15% to about 27% by weight of said composition;
- (c) a non-granulated perborate monohydrate wherein the total amount of granulated and non-granulated perborate monhydrate is in an amount of from about 30% to about 45% by weight of said denture cleansing composition;
- (d) an effective amount of one or more proteolytic enzymes to disrupt the proteinaceous material in plaque;
