Abstract
A cleansing composition is disclosed comprising at least one oxidizing agent including an alkali monopersulfate salt, in an amount of from 35% to 60% by weight, a bleaching promotor selected from alkali metal and alkaline earth metal halides in up to about 20% by weight, a perborate salt in an amount sufficient to inhibit metal tarnish and corrosion and a compound providing ammonium ion in an amount effective to inhibit emission by the composition of chlorine-like odor or flavor. The composition forms a solution having a pH in the basic range. Solutions containing the present cleaning composition exhibit improved tarnish and corrosion resistance, particularly in the instance where the solutions are used to clean dental appliances having metal parts.
Claims57
A cleansing composition comprising:
- (a) an oxidizing agent containing a monopersulfate salt in an amount of from 35% to 60% by weight;
- (b) a bleaching promoter selected from alkali metal and alkaline earth metal halides, in an amount up to about 20% by weight;
- (c) a perborate salt present in amounts sufficient to inhibit tarnish and corrosion of metal;
- and
- (d) a compound providing ammonium ion in an amount effective to inhibit evolution from said cleansing composition of chlorine-like odor and taste.
The composition of claim 28, wherein said builders are selected from the group consisting of alkali metal carbonates, alkali metal phosphates, and mixtures thereof;
- said sequestrants comprise polyfunctional organic acids, and their alkali metal salts;
- said pH stabilizers comprise sodium hydroxide;
- and said colorants comprise at least one food, drug and cosmetic or drug and cosmetic grade dye or lake.
The composition of claim 29, wherein said builders are selected from sodium carbonate, trisodium phosphate, and mixtures thereof, in a total amount ranging from 20 to 40% by weight;
- said sequestrants comprise the alkali metal salts of ethylenediamine tetraacetic acid in an amount of from 0.3-3.5% by weight;
- and said colorants are selected from food, drug and cosmetic grade dyes or lakes having the individual colors blue, red and green, and mixtures thereof in amounts of up to about 0.5% by weight.
A cleansing composition comprising:
- (a) an oxidizing agent comprising a monopersulfate salt in an amount of from 35% to 60% by weight;
- (b) a bleaching promoter comprising an alkali metal halide in an amount of from 10% to 20% by weight;
- (c) a perborate salt present in an amount of at least 7% by weight to inhibit tarnish and corrosion of metal;
- and
- (d) a compound providing ammonium ion in an amount effective to inhibit evolution from said cleansing composition of chlorine-like odor and taste, said compound present in an amount sufficient to provide from about 0.09% to about 6% of said ammonium ion, based on its monovalent form.
A cleansing composition exhibiting improved tarnish resistance and reduced evolution of chlorine-like odor and taste when disposed in a solution, comprising:
- (a) an oxidizing agent containing a monopersulfate salt in an amount of from 35% to 60% by weight;
- (b) a bleaching promoter comprising an alkali metal halide in an amount ranging from 10% to 20% by weight;
- (c) a perborate salt in an amount of from 7% to 20%, to inhibit tarnish and corrosion of metal;
- and
- (d) a compound providing ammonium ion selected from the group consisting of ammonium chloride, ammonium sulfate, ammonium citrate, ammonium phosphate and mixtures thereof, said compound present in an amount sufficient to provide from about 0.09% to about 6% of said ammonium ion based on monovalent ammonium.
