ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to novel light duty liquid detergent compositions with high foaming and good grease cutting properties and which has a reddish peach color and is color stable at room temperature between a pH of 2 to 11.
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 non ionic 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.
SUMMARY OF THE INVENTION
It has now been found that a reddish peach colored liquid cleaning composition can be formulated with a surfactant, FD&C Red No. 40 dye and, optionally a D&C Acid Red No. 33 dye, sodium bisulfite and a preservative and water wherein the composition is colored stable at room temperature at a pH of 2 to 11.
Cleaning compositions that are formed just using FD&C Red 40 dye in the presence of sodium bisulfite are reddish peach in color, when the composition is first made. At a pH of 9 these cleaning compositions are color stable but at a pH of about 5 to about 7 the cleaning composition is not color stable and a color change from reddish peach to yellow occurs.
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, reddish peach colored light duty liquid detergent of this invention which is color stable at room temperature in a pH range of 2 to 11 comprises a surfactant, a preservative, sodium bisulfite, FD&C Red 40 dye, optionally, a D&C Acid Red No. 33 and water.
DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a reddish peach colored solution which is color stable at room temperature between a pH of 2 to 11 which comprises approximately by weight:
(a) 0 to 40%, more preferably 2% to 40% of at least one surfactant selected from the group consisting of an ethoxylated nonionic surfactant, an anionic surfactant, C

fatty acid monoalkanol amide such as lauryl myristal monoethanol amide, an alkyl polyglucoside surfactant, an amine oxide surfactant and a zwitterionic surfactant and mixtures thereof;
(b) 0.005% to 0.15% of a preservative;
(c) 0.0001% to 0.00010% of a red dye which is FD&C Red Dye No. 40 and can further include a D&C Acid Dye No. 33;
(d) 0.04% to 0.12% of sodium bisulfite; and
(e) the balance being water, and wherein the composition has CIE values under D65 illumination of L* of about 91 to about 92, more preferably about 91.1 to about 91.8; a* of about 18 to about 19; more preferably about 18.25 to about 18.75; and b* of about 6.4 to about 7.4, more preferably about 6.0 to about 7.2.
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

where R is a higher alkyl group of 6 to 23 carbons and R

is an alkyl group of 1 to 17 carbons or hydrogen to for
