ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to novel light duty liquid detergent compositions with high foaming and good grease cutting properties.
FIELD 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 surfactant, lauryol ethylene diaminetriacetate and water.
Accordingly, one object of this invention is to provide novel, high foaming, light duty liquid detergent compositions containing a surfactant and lauryol ethoylene diamine triacetate and water 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 a surfactant, 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.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a light duty liquid detergent which comprises approximately by weight:
(a) 5% to 40%, more preferably 8% to 35% of at least one surfactant selected from the group consisting of an ethoxylated nonionic surfactant, an anionic surfactant, an alkyl polyglucoside surfactant, an amine oxide surfactant, and a zwitterionic surfactant;
(b) 0.5% to 10% more preferably 0.75% to 8% of lauryol ethylene diamine triacetate; and
(c) the balance being water wherein the composition does not contain a glycol ether solvent, a polyoxyalkylene glycol fatty acid, a mono- or di-saccharides, a builder, a polymeric thickener, a clay, ethylene diamine tetraacetic acid, alkali metal salt, hydroxyethylene diamine tetra acetic acid sodium salt, abrasive, silicas, alkaline earth metal carbonates, alkyl glycine surfactant or cyclic imidinium surfactant.
Suitable water-soluble non-soap, anionic surfactants include those surface-active or detergent compounds which contain an organic hydrophobic group containing generally 8 to 26 carbon atoms and preferably 10 to 18 carbon atoms in their molecular structure and at least one water-solubilizing group selected from the group of sulfonate, sulfate and carboxylate so as to form a water-soluble detergent. Usually, the hydrophobic group will include or comprise a C

alkyl, alkyl or acyl group. Such surfactants are employed in the form of water-soluble salts and, the salt-forming cation usually is selected from the group consisting of sodium, potassium, or magnesium, with the sodium and magnesium cations again being preferred.
Examples of suitable sulfonated anionic surfactants are the well known higher alkyl mononuclear aromatic sulfonates such as the higher alkyl benzene sulfonates containing from 10 to 16 carbon atoms in the higher alkyl group in a straight or branched chain, C

alkyl toluene sulfonates and C

alkyl phenol sulfonates.
A preferred sulfonate is linear alkyl benzene sulfonate having a high content of 3- (or higher) phenyl isomers and a correspondingly low content (well below 50%) of 2- (or lower) phenyl isomers, that is, wherein the benzene ring is preferably attached in large part at the 3 or higher (for example, 4, 5, 6 or 7) position of the alkyl group and the content of the isomers in which the benzene ring is attached in the 2 or 1 position is correspondingly low. Particularly preferred materials are set forth in U.S. Pat. No. 3,320,174.
Other suitable anionic surfactants are the olefin sulfonates, including long-chain alkene sulfonates, long-chain hydroxyalkane sulfonates or mixtures of alkene sulfonates and hydroxyalkane sulfonates. These olefin sulfonate detergents may be prepared in a known manner by the reaction of sulfur trioxide (SO

) with long-chain olefins containing 8 to 25, preferably 12 to 21 carbon atoms, and having the formula RCH═CHR
1
where R is a higher alkyl group of 6 to 23 carbons and R
1
is an alkyl group of 1 to 17 carbons or hydrogen to form a mixture of sultones and alkene sulfonic acids which is then treated to convert the sultones to sulfonates. Preferred olefin sulfonates contain from 14 to 16 carbon atoms in the R alkyl gro
