Description

United States Patent 3,342,739 DETERGENT COMPOSITION Garland George Corey, Milltown, and Edward Joseph Kenney, llernardsville, N.J., assignors to Colgate- Palrnolive Company, New York, N.Y., a corporation of Delaware N0 Drawing. Filed June 1, 1964, Ser. No. 371,815 11 Claims. (Cl. 252--152) This invention relates to a detergent composition, and more particularly to a liquid detergent composition particularly suitable for hard surface cleaning as hereinafter described.

Presently, general purpose detergents used for cleaning hard surfaces, e.g. floors, walls, etc., are available in both powder and liquid form adapted to be dissolved in water and applied as solutions. Solid powders generally comprise mixtures of synthetic detergents or soap and alkali and exhibit the well-known disadvantages of powder products, e.g. dustiness, caking, harshness to the skin and difiiculties in measuring and dissolving. Similarly, liquid detergcnts'comprise mixtures of soap or synthetic detergent and alkali solubilized in water or mixtures of soap and hydrocarbon solu-bilized in Water and exhibit the disadvantages associated with these liquid products, e.g. harshness to the skin, temperature instability and a thin, watery appearance. Further, both classes of product generally tend to exhibit wide variations in foaming rability, e.g. thick, copious, long lasting foams which leave streaks and are difficult to rinse away and no-foam compositions which are often unsatisfactory because the average housewife associates foaming with cleaning.

Recognition of the foregoing disadvantages of the present liquid and powder general purpose detergents indicates that there is a definite need for a general purpose detergent composition which possesses desirable cleaning and foaming characteristics at use concentrations and at the same time is mild to the skin. Such characteristics are a significant feature of the invention which is described and claimed herein.

Generally, the new compositions of the invention consist essentially of about one part of la polyethenoxy organic nonionic detergent, about 0.4 to about 3 parts of an ethoxylated higher fatty acid alkylolamide condensate containing an average of about one to about four ethylene oxide groups and above 0.05 to about 0.3 part of fatty acids containing about 10-14 carbon atoms in the acyl group, the pH of a mixture of the above ingredients in a concentration of about 7-30% by. weight in water being from 6.9 to about 7.5.

More particularly, it has been found that a liquid detergent composition having superior qualities can be formulated which consists essentially of about 70-93% by weight of water and from about 7-30% by weight of a mixture of (a) about one part of a nonionic detergent selected from the class consisting of polyethenoxy ethers of alkyl phenols containing from about 3 to 10 carbon atoms in the alkyl group and about to 12 ethylene oxide groups and polyethenoxy ethers of higher aliphatic alcohols containing about to 20 carbon atoms in the aliphatic group and 1 to 10 ethylene oxide groups, (b) about 0.4 to about 3 parts of an ethoxylated higher fatty acid alkylolamide containing an average of one to about four ethylene oxide groups and selected from the class consisting of monoethanolamides, diethanolamides and isopropanolarnides of fatty acids containing about 10-14 carbon atoms in the acyl group and (c) about 0.05 to about 0.3 part of fatty acids containing about 10-14 carbon atoms in the acyl group, the pH of said composition being from the range of about 6.9 to about 7.5.

Patented Sept. 19, 1967 This detergent composition is characterized by many desirable properties. The described composition results in a liquid detergent product which is clear within the 40 F. F. temperature range, has a substantially neutral pH which is mild to the skin, has a desirable foam balance, e.g. high flash foam during dilution which falls to a low residual foam at use concentration to minimize rinsing and streaking problems, exhibits excellent detergency particularly with respect to waxed floors where cleaning is accomplished without significantly disturbing the wax surface so that a rebuifable surface results and exhibits a desirable viscosity of about to about 1000 centipoises as measured with a Brookfield Viscometer, Model HAP, using a #1 spindle at 10 rpm. These and other desirable features will be apparent as the invention is described.

A preferred embodiment is represented by a composition particularly suitable for the cleaning of waxed tiled floors consisting essentially of about 70-93% by weight of water and from about 730% by weight of a mixture of (a) about one part of a nonionic detergent selected from the class consisting of polyethenoxy ethers of alkyl phenols containing from about 8 to 10 carbon atoms in the alkyl group and about 5 to 12 ethylene oxide groups and polyethenoxy ethers of higher aliphatic alcohols containing about 10 to 20 carbon atoms in the aliphatic group and about 3 to 10 moles of ethylene oxide, (b) about 0.1 to about 0.7 part of a water soluble salt of an organic reaction product having in its molecular structure an anionic solubilizing group selected from the group consisting of S0 and S0 and an alkyl or aralkyl radical having about 8 to 18 carbon atoms in the alkyl group, (c) about 0.4 to about 3 parts of a mixture of an ethoxylated higher fatty acid alkylolamide containing an average of one to about four ethylene oxide groups and a nonethoxylated fatty acid alkylolamide, said alkylolamides being selected from the class of monoethanolamides, diethanolamides and isopropanolamides of fatty acids having about 10-14 carbon atoms in the fatty acyl group, the ratio of ethoxylated to non-ethoxylated fatty acid alkylolamides being from about 99:1 to about 25:75 and (d) about 0.05 to about 0.3 part of fatty acids containing about 10 to about 14 carbon atoms in the acyl group, said composition having a pH from the range of about 6.9 to about 7.5 and exhibiting a desirable viscosity within the range of about 125 to about 1000 centipoises.

The nonionic organic detergents which may be employed in the composition of the invention include the polyethenoxy ethers of a non nitrogen containing hydro phobic organic compound having at least eight carbon atoms in its molecular structure such as alkyl phenols and higher aliphatic alcohols.

The suitable polyethenoxy ethers of alkyl phenols are generally condensates of ethylene oxide with alkyl phenols. The phenols are generally monoalkylated and the total number of carbon atoms in the alkyl chain may vary from about 3 to 10 carbon atoms. The alkyl chain may be either branch chained, e.g. derived from polypropylene, or straight chained, e.g. ethylene derived and kerosene derived. The degree or proportion of hydrophilic ethenoxy groups will vary with the specific hydrophobic group, but generally will be suificient to confer the desired water solubility and detersive properties. Ususally at least about 5 and up to about 12 ethylene oxide groups can be present. As used herein the terms groups and moles are used interchangeably with respect to ethylene oxide. Suitable compounds include polyoxyethylene nonylphenol, polyoxyethylene octylphenol, and polyoxyethylene decyl phenol.

Other suitable polyethenoxy organic nonionic detergents are the polyethenoxy ethers of higher aliphatic alcohols of more than eight carbon atoms. Suitable fatty alcohols having the desired hydrophobic character, preferably 10 to 20 carbon in their molecular structure are lauryl, tridecyl, myristyl, cetyl alcohols and mixtures thereof condensed with an appropriate amount of ethylene oxide such as at least one, and preferably about 3 to 10 moles. The aliphatic group may be either straight chained, e.g. fatty derived and ethylene derived, or branch chained, e.g. oxo-alcohols.

The foregoing nonionic detergents may also be used in combination with each other. In addition, the nonionic detergents, or admixtures thereof, may be further combined with a suitable anionic detergent.

Among the suitable anionic detergents for use in conjunction with the described nonionic detergents are the water soluble salts of an organic reaction product having in its molecular structure an anionic solubilizing group selected from the group consisting of S and S0 and an alkyl or aralkyl radical having about 8 to 18 carbon atoms in the alkyl group. Suitable anionic detergents include the water soluble higher alkyl mononuclear aryl sulfonate salts and the water soluble alkali metal salts of the sulfuric esters of polyethenoxy ethers of alkyl phenols and higher aliphatic alcohols.

The water soluble higher alkyl mononuclear aryl sulfonate salt detergent having about 8 to 15 carbon atoms in the alkyl group which it is preferred to use is alkyl benzene sulfonate, though other similar detergents having a mononuclear aryl nucleus, such as alkyl toluene and alkyl Xylene sulfonates, may be used. The alkyl substituents may be branched such as nonyl, dodecyl and pentadecyl groups including mixtures thereof which are derived from polymers of lower mono-olefins, e.g. propylene. The alkyl group may be straight-chained in structure such as the n-decyl, keryl and dodecyl groups. Preferred examples of this class are the alkyl benzene sulfonates having an average of about 12 to 15 carbons in the alkyl group. These sulfonate detergents are used in the form of their water-soluble alkali metal or hydroxyalkyl ammonium salts such as the sodium or potassium or triethanolamine salts. It is understood that there may be small amounts of inorganic salts such as sodium sulfate in the sulfonated detergent resulting from the method of manufacture. In general, these inorganic sulfate salts should be maintained at as low a concentration as practicable.

The alkali metal salts of aliphatic primary and secondary alcohol sulfates such as sodium lauryl alcohol sulfate are also satisfactory anionic detergents.

The sodium, potassium or hydroxyalkylammonium salts of the sulfuric acid esters of the polyethenoxy ethers of alkyl phenol and higher aliphatic alcohols are also effective in conjunction with the nonionic detergent. The preferred alkyl phenols contain about 6 to 12 carbon atoms in the alkyl group and the preferred alcohols contain about to 20 carbon atoms in the aliphatic group. The number of ethylene oxide groups will vary with the specific hydrophobic group and usually will average from at least 1 to about 10 groups.

When using anionic detergents in admixture with the nonionic detergents, it is preferred to maintain nonionic-anionic ratios in the 90:10 to 60:40 range. The presence of at least 10% anionic based on total nonionic-anionic weight basis is required to connote any advantage, and more than 40% anionic on the combined detergent basis results in too much residual foam and therefore rinsing problems. Thus, compositions containing one part of nonionic detergent and about 0.1 to about 0.7 part of anionic detergent are preferred.

The ethoxylated higher fatty acid alkylolamides which may be employed in the composition of the invention include the ethoxylated monoethanolamides, diethanolamides and isopropanolamides of fatty acids containing about 10 to 14 carbon atoms in the acyl group wherein the average number of ethylene oxide groups varies from 4- about one to about four. A preferred compound is the diethoxylated coconut monoethanolamide.

The ethoxylated higher fatty acid alkylolamides may be used alone or in combination with non-ethoxylated higher fatty acid alkylolamides. However, at least about 25% by weight of the sum total of fatty acid alkylolamide and ethoxylated fatty acid alkylolamide should consist of ethoxylated fatty acid alkylolamide. Non-ethoxylated higher fatty acid alkylolamides suitable for use in combination with the ethoxylated fatty acid alkylolamides are the monoethanolamides, diethanolamides and isopropanolamides of fatty acids having about 10 to 14 carbon atoms in the fatty acyl group. Examples are lauric, capric, myristic and coconut monoethanolamide, diethanolamide and isopropanolamide.

Free fatty acids suitable for use in this composition are the fatty acids containing about 10-14 carbon atoms and mixtures thereof. Examples are coconut, lauric, capric, and myristic acids.

The solids content of the liquid product is variable and usually the total amount of water is at least about 70%. It is understood that the amount of water and other ingredients will be suitably proportioned to provide solubilizing effects so as to form a homogeneous, clear liquid.

Various other ingredients may be added or substituted if desired. The compositions can beneficially contain chelating agents, either organic or inorganic compounds, capable of complexing with iron, calcium, magnesium and the like. Generally, the Water soluble salts of ethylenediamine tetraacetic acid are preferred. Inorganic sequestering agents include citric acid, alkali metal polyphosphate and the like. Normally, such agents are employed in small amounts, generally about 0.2-0.5 percent by weight in compositions prepared in liquid medium. Dyes, perfumes and the like can also be utilized in small amounts where desired.

In the formulation of the products of the present invention, there are a number of factors which are of consideration as described. As indicated, the ratios of the detergent to the ethoxylated alkylolamide and fatty acid are an important consideration because the properties of the finished product are effected by the foregoing ratios. For example, evaluation of the composition of this invention in dilute solution for use in cleaning waxed floor tiles reveals the importance of the ratio of nonionic organic detergent to ethoxylated fatty acid alkylolamide as set forth in the following table. In this test, 4" x 4" vinyl tiles were waxed with a commercial floor wax containing a fluorescent brightener, Tinopal RES 200, therein, and one half of the tile was Washed with a 2% product concentration in water at 70 F., rinsed and allowed to dry. The tiles were then evaluated for wax removal by visually comparing with the unwashed portion of the tile using an ultraviolet light source. The product composition contained 14.5% of a mixture of nonylphenol containing 9.5 moles of ethylene oxide and diethoxylated coconut monoethanolamide in varying ratios, 0.5% of coconut fatty acid and water.

TABLE I Ratio of ethoxylated fatty acid Percent wax alkylolamide to nonionic detergent: removal All nonionic +50 .45/1 10 1/ 1 5 2 2/ 1 +25 The foregoing results clearly show that minimum wax removal is obtained using compositions having an ethoxylated fatty acid alkylolamide to nonionic detergent ratio within the claimed 0.43 range and a fatty acid to nonionic detergent ratio within the claimed 0.05-0.3 range.

Similarly, it is necessary to properly select and correlate the other factors to provide the product hereafter claimed as described in the following examples. The following examples are given additionally to illustrate the nature of the invention and it will be understood that the invention is not limited thereto. All parts or per- 6 Compositions of the type illustrated in Example II also demonstrate the significance of the fatty acid component in the present inventions and the unobvious technical properties resulting thereby.

The composition in Example II is a clear, homogeneous liquid detergent at room temperature having a pH of 7.2. Brookfield viscosity was 230 cps. and the initial foam height was 75 ml. in the cylinder foam test which fell to 1 ml. within five minutes.

The significance of the ethoxylated fatty acid alkylolamide concentration is clearly demonstrated in compositions of the foregoing nature. Elimination of the diethoxylated coconut monoethanolamide and an increase in the coconut diethanolamide concentration in the composition of Example II yields a product of the thin, watery type, (Brookfield viscosity approximately 35 cps.) and results in a residual foam of 25 ml. A definite quantity of ethoxylated fatty acid alkylolamide is required to provide the desired viscosity and foaming characteristics. Such results make it very apparent that fatty acid alkylolamides are not equivalents of the ethoxylated fatty acid alkylolamides in compositions of our invention.

The above products are clear at room temperature and maintain clarity over the 40-120 F. temperature range. Viscosities of the mild, about 6.9 to about 7.5 pH products fall Within the range of about 125 to about 1,000 c.p.s. as measured on the Brookfield viscometer. All of the compositions exhibit satisfactory cleaning power when the compositions are diluted to 2% with Water.

The new compositions of this invention are prepared in any suitable manner such as by mixing the active constituents together in the presence of approximately 30% of the water and agitating or stirring until a substantially homogeneous mixture results. The active components are preferably added in molten or liquid form and the temperature of the admixture should be sufiicient to promote attainment of a homogeneous mixture. Reasonably elevated temperatures such as up to C. may be employed as required, although 40 50 C. is normally satisfactory. The remainder of the water (cold) is then added along with any desired adjuvants. The liquid compositions as made may be slightly too alkaline or too acidic to yield a neutral product having a high viscosity, e.g. about 125-1000 centipoises is desired, and minor amounts of sulfuric acid or caustic will then be required to adjust the pH to the range of about 6.9 to about 7.5.

Generally, before application to a surface for cleaning, the compositions of the invention are diluted with water to provide a cleaning solution of desired concentration to effect good cleaning of the surface to which they are applied. The total concentration of the liquid medium plus active constituents is not critical, but is limited by economic practicalities. However, in diluted solutions, product concentrations of .75 to 6 percent by weight and preferably from 1.5 to 3 percent by weight are excellent for routine cleaning of hard surfaces such as walls, floors, tiles, etc.

Compositions of this invention were evaluated in dilute Water solutions for use in commercial floor cleaning operations, a commercial hard surface cleaning operation, and achieved cleaning with only minimal wax removal, thereby leaving a re-buffable surface after washing. This clearly illustrates another useful advantage for composi tions of the invention.

In review, the new compositions of this invention present many advantages. The compositions can be used to clean a Wide variety of surfaces Without fear of damage to the surface. Further, the neutral cleaning solutions present no danger of detergent or alkali burn to the user. No rinsing is required after Washing because of low residual foam; yet, sufficient initial foam is apparent to prevent use of wasteful product concentrations which may occur when using low foam products. Viscosity characteristics of the liquid compositions offer a welcome departure from the usual thin, watery liquids and result in aesthetic and consumer appeal.

Although the present invention has been described with reference to particular embodiments and examples, it will be apparent to those skilled in the art that variations and modifications to this invention can be made and equivalents can be substituted therefor without departing from the principles and true spirit of the invention.
