ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to novel light duty liquid cleaning compositions with high foaming properties and having the appearance of suspended beads therein which contains a sulfonate surfactant, an ethoxylated alkyl ether sulfate surfactant, a nonionic surfactant, gelatin beads containing an oil, a crosslinked polyacrylate type polymer, an inorganic magnesium salt, a polyethylene glycol and the balance being water.
BACKGROUND OF THE INVENTION
Nonionic surfactants are in general chemically inert and stable toward pH change and are therefore well suited for mixing and formulation with other materials. The superior performance of nonionic surfactants on the removal of oily soil is well recognized. Nonionic surfactants are also known to be mild to human skin. However, as a class, nonionic surfactants are known to be low or moderate foamers. Consequently, for detergents which require copious and stable foam, the application of nonionic surfactants is limited. There have been substantial interest and efforts to develop a high foaming detergent with nonionic surfactants as the major ingredient. Yet, little has been achieved.
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, as shown in U.S. Pat. No. 3,658,985 wherein 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 0.8-20% 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 based on the alkali metal silicate content and containing five basic ingredients, namely, 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 property of these detergent compositions is 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 is 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 specific class of anionics utilized in this patent is the very same group of anionic detergents expressly excluded in present invention in order to eliminate the alkanol ethoxylate sulfation process and the potential dioxane toxicity problem. Furthermore, this patent finds heavily foaming detergents undesirable for the purpose of washing socks.
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 effect 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 polyoxybutylene polyoxyethylene nonionic detergent, an anionic surfactant, a fatty acid alkanolamide and a polyoxyalkylene glycol fatty ester. But, none of the exemplified compositions in contains an active ingredient mixture wherein the nonionic detergent is present in major proportion, 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

fatty acid monoethanolamide foam stabilizer.
U.S. Pat. 5,866,529 teaches a light duty liquid cleaning composition containing gelatin beads and a Laponite clay, wherein this patent specifically excludes polyacrylic acid polymeric thickeners.
However, none of the above-cited patents discloses a high foaming, liquid detergent composition containing a nonionic surfactant, two high foaming anionic surfactants, an inorganic magnesium salt, polyethylene glycol, an oil containing gelatin bead, a crosslinked polyacrylate polymer and water wherein the composition does not contain any polymeric thickeners such as cellulosics or xanthan gum or a Laponite clay.
SUMMARY OF THE INVENTION
It has now been found that a high foaming liquid light duty liquid cleaning composition has desirable cleaning properties, mildness to the human skin and improved aesthetics. Accordingly, one object of the invention is to provide novel, high foaming, light duty liquid detergent compositions containing a nonionic surfactant, suspended oil containing gelatin beads and a polyacrylate type polymeric thickener.
Another object of this invention is to provide novel, liquid detergent compositions containing a nonionic surfactant, two anionic surfactants, an inorganic magnesium salt, polyacrylate type polymer, suspended oil containing gelatin beads and water [wherein the composition does not contain any builder salts, polymeric thickeners such as cellulosics or xanthan gum, alkyl glycine surfactant, Laponite clay, cyclic imidinium surfactant, N-polyvinyl pyrrolidone homopolymer, copolymer of N-polyvinyl pyrrolidone and dimethyl-aminoethyl methacrylate, or abrasives].
Still another object of this invention is to provide a novel, liquid detergent with a desirable high foaming and cleaning properties which is mild to the human skin.
Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
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 cleaning compositions of this invention comprises a water soluble, ethoxylated, nonionic surfactant, two anionic surfactants selected from the group consisting of water soluble organic sulfates and organic sulfonates, suspended oil containing gelatin beads, wherein the composition does not contain any formate, HETDA, abrasives, builder salts, polymeric thickeners such as cellulosics or xanthan gum, a Laponite clay, fatty acids, alkyl glycine surfactant or cyclic imidinium surfactant.
