Abstract
Aqueous hypochlorite-containing cleansing compositions for use on porcelain enamel surfaces wherein said compositions contain a sufficient amount of water-soluble fluoride salt and a clay with cation exchange capacity to inhibit discoloration of the surface by the hypochlorite.
Claims11
An aqueous, hard surface cleansing composition comprising:
- a. from about 0.1% to about 50% of a compound which releases hypochlorite ions in aqueous solution;
- b. from about 0.1% to about 30% of a mineral clay having a cation exchange capacity of at least 3 milliequivalents of cation per 100 grams of clay;
- c. from 0% to about 25% of a surfactant which is compatible with hypochlorite;
- d. from 0% to about 65% of a particulate abrasive having a paticle size of from about 1 to about 250 microns and a specific gravity of from about 0.2 to about 2.2;
- e. from 0% to about 50% of a water-soluble, inorganic alkaline salt or mixture of such salts;
- f. an amount of a source of soluble fluoride ions which provides at least 0.01% of fluoride ions to said composition;
- and
- g. the balance of said composition comprising water.

An aqueous, abrasive hard surface cleansing composition comprising:
- a. from about 0.1% to about 30% of a mineral clay having a cation exchange capacity of at least 3 milliequivalents of cation per 100 grams of clay;
- b. from about 2% to about 25% by weight of a particulate abrasive material, substantially all of said material ranging in particle size from 1 micron to about 250 microns, said material having an average specific gravity ranging from about 0.2 to 2.2;
- c. from about 0.1% to about 10% of a bleaching agent which releases hypochlorite ions in aqueous solution;
- d. a source of fluoride ion in sufficient amount to provide at least about 0.01% fluoride ion in said composition;
- e. from about 1% to about 20% of an alkaline inorganic salt or mixture of such salts;
- f. from 0% to about 25% of a surfactant which is compatible with hypochlorite;
- and
- g. the balance of said composition comprising water.
