Description
United States Patent US. Cl. 252--545 7 Claims ABSTRACT OF THE DISCLOSURE A jellylike composition for the pre-washing treatment of textiles, comprising 8-30 wt. percent of a straight chain or branched chain alkylbenzenesulfonate, 10-62 wt. percent of a nonionic surfactant of the amphiphilic polyoxyethylene type and the remainder is water, the sum of said alkylbenzenesulfonate and said nonionic surfactant of the amphiphilic polyoxyethylene type being 25-70 wt. percent of the total weight of the composition.
BACKGROUND OF THE INVENTION Field of the invention The present invention relates to jellylike or semisolid detergent compositions containing, as essential ingredients, straight chain or branched chain alkylbenzenesulfonate, nonionic surfactant of the amphiphilic polyoxyethylene type and water. These compositions are suitably used by applying them to heavily stained portions of clothing, such as collars, cuffs, socks and underwear by a brush or by the users fingers and then placing the goods into a Washing machine. The compositions can also be used by applying them to materials which cannot be washed by vigorous hand washing or in a washing machine, such as frilly materials, laces and sweaters and then Washing the materials gently with a brush or by light pressing.
Description of the prior art As is well known, general purpose household detergents comprising a surfactant and a builder do not have sufficient power to remove oily dirt and, therefore, soiled materials washed therewith may yellow after storage for a long period of time. Heavily stained portions cannot be cleansed sufficiently by the usual washingprocess and, therefore, a more concentrated detergent solution is sometimes used. However, such a treatment is not preferred for general household use because of the difficulty of using same and/or it may damage the fabric or damage the shape of the clothing.
On the other hand, cleaning with solvents (dry cleaning) is suitable for removing oily dirt. However, this method has the disadvantage that water-soluble dirt and inorganic solid dirt cannot be removed. A system has been developed wherein a W/O detergent comprising a surfactant, a small quantity of water and a solvent'is used. However, this system is not suitable for general household use, because a large quantity of a solvent is required.
We have desired to incorporate in adetergent composition an amphiphilic substance having a high afiinity for oily dirt, as an agent for positively removing oily dirt from clothing, thereby contributing to the effective cleaning of clothing. 7
It has been found, however, that the efiect of the amphiphilic substances cannot be obtained if the amphiphilic substances are incorporated in an ordinary synthetic detergent composition and such composition is used for washing in the form of an aqueous detergent solution of a low concentration in the usual manner, because the amphiphilic substances can be used only in small amounts and they are difficultly soluble in water.
We have discovered the present invention after intensive investigations. We employ jellylike compositions, which are generally in the form of liquid crystals and which comprise a surfactant/amphiphilic substance/water system, and in which the amphiphilic substance exhibits an improved effect of removing oily dirt from textiles.
SUMMARY OF THE INVENTION The present invention provides jellylike or semisolid compositions containing three essential ingredients, namely, (1) 8-30 wt. percent, preferably 10-20 wt. percent, of straight chain or branched chain 'alkylbenzenesulfonate as a surfactant, (2) 10-62 wt. percent, preferably 15-50 wt. percent, of a nonionic active agent of the polyoxyethylene type as the amphiphilic substance and (3) the remainder is water. The sum of said alkylbenzenesulfonate and said amphiphilic nonionic active agent of the polyoxyethylene type in the composition is 25-70 wt. percent, preferably 35-50 wt. percent, based on the total weight of the composition.
The straight chain or branched chain alkylbenzenesulfonates used in the present invention are, for example, the alkali metal salts such as the sodium or potassium salts, or the organic amine salts such as the monoethanolamine and diethanolamine salts, of alkylbenzenesulfonates containing alkyl groups having 8-18 carbon atoms. Sodium salts of straight chain alkylbenzenesulfonates in which the alkyl group has 10-15 carbon atoms are particularly preferred.
The nonionic active agents of the amphiphilic polyoxyethylene type used in the present invention are those having an HLB value in the range of 5-11 including, for example, polyoxyethylene alkyl ethers containing alkyl groups of 8-22 carbon atoms and 1-8 oxyethylene units and polyoxyethylene alkylphenyl ethers containing alkyl groups of 8-18 carbon atoms and 1-8 oxyethylene units. Polyoxyethylene (4-6) nonylphenyl ethers and polyoxyethylene (3-5) dodecyl ethers are particularly preferred.
In order to obtain the synergistic effect on the deterging power of the compositions of the present invention and to obtain a jellylike or semisolid form, the amount of the surfactant is generally in the range of 8-30 wt. percent, preferably 10-20 wt. percent, and the amount of the amphiphilic substance is generally in the range of 10-62 wt. percent, preferably 15-50 wt. percent, both percentage ranges being based on the total weight of the composition. The amounts of each component vary within the above-stated ranges depending on the particular compounds of both components that are used. The sum of both components is 25-70 wt. percent, preferably 35-50 wt. percent, based on the total weight of the composition.
The jellylike detergent compositions according to the invention can be prepared by (A) dissolving the alkylbenzenesulfonate surfactant in water to obtain a homogenous solution and then adding the amphiphilic substance to the solution with stirring, or (B) by stirring together the surfactant, the amphiphilic substance and water. The former method is preferred to the latter, because it yields a more homogeneous mixture and thereby provides a harder or more viscous gel.
The jelly composition of the present invention is used by applying it to cloth, in an amount in the range of 0.3-1.0 g., preferably 0.5 g., per one piece of cloth of a size of 50 cmfl, by the users fingers or with a brush. The cloth'may be washed in a washing machine immediately after application of the composition. However, improved results are obtained by allowing the treated cloth to stand for about 30 minutes before washing it.
Further, even better results are obtained by brushing the surface after it has been treated with the composition according to the invention.
part of the amphiphilic substance contained in the jelly composition of the present invention may be replaced with a solvent such as ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, ethylene glycol monophenyl ether or diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, a wetting agent or a wetting promotor such as a dialkylsulfosuccinate. The dialkylsulfosuccinates to be optionally'used in the present invention are, for example, the alkali metal salts such as the sodium or potassium salts, or the organic amine salts such as the monoethanolamine and diethanolamine salts, of dialkylsulfosuccinates containing straight chain or branched chain alkyl groups having 6-10 carbon atoms. Sodium diethylhexylsulfosuccihate is particularly preferred. The solvent can be used in an amount of up to 6 Wt. percent of the composition and also the wetting agent or promoter can be used in an amount of up to 5 wt. percent of the composition.
By using the jelly detergent of the present invention, heavy dirt, particularly oily dirt on collars, cuffs, socks and underwear, can be removed easily as a result of the synergism of the amphiphilic substance and the alkylbenzenesulfonate surfactant and troublesome repetition of washing procedure is not required. The jelly detergent is suitable for washing materials which cannot be hand-washed by a vigorous crumpling action or which cannot be washed in a washing machine such as frilly materials, laces and sweaters, by spreading the composition of the invention on said materials and then washing them lightly with a brush or by light pressing.
The present invention will be further illustrated in the following representative Examples. In the Examples, parts are all by weight.
