Description

STAINLESS COLOR PLATE LIQUID CLEANING COMPOSITIONS CONTAINING A PEROXIDE SOURCE Field of the Invention This invention relates to a color stable liquid plate cleaning composition which is designed to remove surface stains, disinfect surfaces such as dishes, countertops, sponges, while maintaining good foam, grease cutting, properties of rinse and softness. The composition also exhibits excellent stability in terms of color and peroxide level.

Background of the Invention The present invention relates to novel stable stable light-duty liquid detergent compositions with high foaming and good grease-cutting properties as well as disinfecting properties.

The prior art is replete with heavy duty liquid detergent compositions containing nonionic surfactants in combination with anionic and / or betaine surfactants wherein the nonionic detergent is not the main active surfactant. In U.S. Patent No. 3,658,985 an anionic base shampoo contains a minor amount of a fatty acid alkanolamide. U.S. Patent No. 3,769,398 describes a botaine-based shampoo containing minor amounts of non-ionic surfactants. This patent states that the low foaming properties of non-ionic detergents make their use in non-preferred shampoo compositions. U.S. Patent No. 4,329,335 also discloses a shampoo containing a betaine surfactant as the main ingredient and minor amounts of nonionic surfactant and of a mono- or di-ethanolamide of fatty acid. U.S. Patent No. 4,259,204 discloses a shampoo composition comprising 0.8 to 20% by weight of anionic phosphoric acid ester and an additional surfactant can be either anionic, amphoteric or non-ionic. U.S. Patent No. 4,329,334 discloses an anionic-amphoteric base shampoo containing a major amount of anionic surfactant and minor amounts of non-ionic surfactants and betaine.

U.S. Patent No. 3,935,129 describes a liquid cleaning composition containing an alkali metal silicate, urea, glycerin, trietranolamine, an anionic detergent and a nonionic detergent. The silicate content determines the amount of the anionic and / or nonionic detergent in the liquid cleaning composition. However, the foam properties of these detergent compositions are not discussed here.

The patent of the United States of America No.

No. 4,129,515 discloses a heavy duty liquid laundry detergent comprising fabrics comprising a mixture of essentially equal amounts of anionic and nonionic surfactants, alkanolamines, and magnesium salts, and optionally zwitterionic surfactants such as foam modifiers.

U.S. Patent No. 4,224,195 discloses an aqueous detergent composition for washing socks and stockings comprising a specific group of non-ionic detergents, namely, an ethylene oxide of a secondary alcohol, a specific group of anionic detergents , namely, a sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol, and an amphoteric surfactant which may be a betaine wherein either the anionic or nonionic surfactant may be the main ingredient.

The prior art further discloses detergent compositions containing all nonionic surfactants as shown in U.S. Patent Nos. 4,154,706 and 4,329,336 wherein the shampoo compositions contain a plurality of particular non-ionic surfactants in order to affect the desirable foaming and detersive properties despite the fact that non-ionic surfactants are usually deficient in such properties.

U.S. Patent No. 4,013,787 discloses a piperazine-based polymer in conditioning and shampoo compositions which may contain all of the nonionic surfactant or an entire anionic surfactant.

U.S. Patent No. 4,450,091 discloses high viscosity shampoo compositions containing a mixture of an amphoteric betaine surfactant, a nonionic polyoxybutylene polyoxyethylene detergent, an anionic surfactant, a fatty acid alkanolamide and a fatty acid ester of polyoxyalkylene glycol. But none of the exemplified compositions contains a mixture of active ingredient in which the nonionic detergent is present in a higher proportion which is probably due to the low foaming properties of said nonionic polyoxybutylene polyoxyethylene detergent.

U.S. Patent No. 4,595,526 describes a composition comprising a nonionic surfactant, a betaine surfactant, an anionic surfactant and a C 12 -C 14 fatty acid monoethanolamide foam stabilizer.

U.S. Patent No. 6,147,039 teaches an antibacterial hand cleaner composition having a low surfactant content.

The polyethylene glycol which is used in the present composition has a molecular weight of 200 to 1,000 wherein the polyethylene glycol has the structure: HO (CH2CH20) nH wherein n is from 4 to 52. The concentration of the polyethylene glycol in the present composition is from 0.1% to 7% by weight, more preferably from 0.1% by weight to 5% by weight.
