ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to novel light duty liquid detergent compositions with high foaming and good grease cutting properties.
BACKGROUND OF THE INVENTION
The prior art is replete with light duty liquid detergent compositions containing nonionic surfactants in combination with anionic and/or betaine surfactants wherein the nonionic detergent is not the major active surfactant. In U.S. Pat. No. 3,658,985 an anionic based shampoo contains a minor amount of a fatty acid alkanolamide. U.S. Pat. No. 3,769,398 discloses a betaine-based shampoo containing minor amounts of nonionic surfactants. This patent states that the low foaming properties of nonionic detergents renders its use in shampoo compositions non-preferred. U.S. Pat. No. 4,329,335 also discloses a shampoo containing a betaine surfactant as the major ingredient and minor amounts of a nonionic surfactant and of a fatty acid mono- or di-ethanolamide. U.S. Pat. No. 4,259,204 discloses a shampoo comprising 0.8 to 20% by weight of an anionic phosphoric acid ester and one additional surfactant which may be either anionic, amphoteric, or nonionic. U.S. Pat. No. 4,329,334 discloses an anionic-amphoteric based shampoo containing a major amount of anionic surfactant and lesser amounts of a betaine and nonionic surfactants.
U.S. Pat. No. 3,935,129 discloses a liquid cleaning composition containing an alkali metal silicate, urea, glycerin, triethanolamine, an anionic detergent and a nonionic detergent. The silicate content determines the amount of anionic and/or nonionic detergent in the liquid cleaning composition. However, the foaming properties of these detergent compositions are not discussed therein.
U.S. Pat. No. 4,129,515 discloses a heavy duty liquid detergent for laundering fabrics comprising a mixture of substantially equal amounts of anionic and nonionic surfactants, alkanolamines and magnesium salts, and, optionally, zwitterionic surfactants as suds modifiers.
U.S. Pat. No. 4,224,195 discloses an aqueous detergent composition for laundering socks or stockings comprising a specific group of nonionic 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 major ingredient.
The prior art also discloses detergent compositions containing all nonionic surfactants as shown in U.S. Pat. Nos. 4,154,706 and 4,329,336 wherein the shampoo compositions contain a plurality of particular nonionic surfactants in order to affect desirable foaming and detersive properties despite the fact that nonionic surfactants are usually deficient in such properties.
U.S. Pat. No. 4,013,787 discloses a piperazine based polymer in conditioning and shampoo compositions which may contain all nonionic surfactant or all anionic surfactant.
U.S. Pat. No. 4,450,091 discloses high viscosity shampoo compositions containing a blend of an amphoteric betaine surfactant, a polyoxybutylenepolyoxyethylene nonionic detergent, an anionic surfactant, a fatty acid alkanolamide and a polyoxyalkylene glycol fatty ester. But, none of the exemplified compositions contain an active ingredient mixture wherein the nonionic detergent is present in major proportion which is probably due to the low foaming properties of the polyoxybutylene polyoxyethylene nonionic detergent.
U.S. Pat. No. 4,595,526 describes a composition comprising a nonionic surfactant, a betaine surfactant, an anionic surfactant and a C

SUMMARY OF THE INVENTION
It has now been found that a high foaming liquid detergent properties can be formulated with a paraffin sulfonate, an alpha olefin sulfonate, an amine oxide, lauryol ethylene diaminetriacetate and water.
The present invention also relates to a formula containing an alkyl polyglucoside surfactant, an ethoxylated alkyl ether sulfate surfactant, at least one linear alkyl benzene sulfonate surfactant, an inorganic magnesium salt, optionally, optionally, triclosan, a fatty acid monoalkanol amide, lauryol ethylene diamine triacetate and water.
Accordingly, one object of this invention is to provide novel, high foaming, light duty liquid detergent compositions containing an alpha olefin sulfonate surfactant and lauryol ethylene diamine triacetate which has both good grease cutting and excellent disinfecting properties on hard surfaces.
To achieve the foregoing and other objects and in accordance with the purpose of the present invention, as embodied and broadly described herein the novel, high foaming, light duty liquid detergent of this invention comprises an alpha olefin sulfonate, a paraffin sulfonate, an amine oxide, lauryol ethylene diamine triacetate and water, wherein the composition does not contain an alkali metal salt of ethylene diamine tetraacetic acid or hydroxy ethylene diamine tetra acetic acid, a glycol ether solvent, a mono- or di-saccharides, a polyoxyalkylene glycol fatty acid, a builder, a polymeric thickener, a clay, a fatty acid alkanolamide, abrasive, silicas, alkaline earth metal carbonates, alkyl glycine surfactant or cyclic imidinium surfactant.
To also achieve the foregoing and other objects and in accordance with the purpose of the present invention, as embodied and broadly described herein the novel, high foaming, light duty liquid detergent of this invention comprises a linear alkyl benzene sulfonate, an ethoxylated alkyl ether sulfate, an alkyl polyglucoside, an inorganic magnesium compound, lauryol ethylene diamine triacetate and water, wherein the composition does not contain an alkali metal salt of ethylene diamine tetraacetic acid or hydroxy ethylene diamine tetra acetic acid, a glycol ether solvent, a mono- or di-saccharides, a polyoxyalkylene glycol fatty acid, a builder, a polymeric thickener, a clay, a fatty acid alkanolamide, abrasive, silicas, alkaline earth metal carbonates, alkyl glycine surfactant or cyclic imidinium surfactant.
