Description
1090~;71 HARD SURFACE DETERGENT COMPOSITION
This invention relates to detergent compositions and more particularly to an improved detergent composition for cleaning hard surfaces comprising a mixture of a non-ionic detergent, a tertiary amine oxide, and a quaternary ammonium halide, the combination of these ingredients ex-hibiting improved detergent properties compared to com-positions containing any one or two of said ingredients at equivalent concentrations.
Hard surface detergents, with which this invention 10' is concerned, are intended for cleaning surfaces such as those of painted wood, plaster or wall board, tile, glass, metal, linoleum and the like, which tend to accumulate a soil containing both solid as well as oily substances~ To be suitable for such use, a hard surface detergent should have high solvent power for both solid and oily soils, and great miscibility with water, in order to permit dilution over a wide range of concentrations as well as to facilitate rinsing of the surface after the cleaning operation is completed. In addition to its solvent power and miscibility with water, an ideal hard surface detergent composition should be biodegradable,non-toxic and non-irri-tating to the skin, and it should give off no obnoxious or irritating fumes.
In accordance with the invention, an improved hard surface detergent composition having the above-described properties comprises an aqueous solution of a non-ionic detergent characterized by having a polyoxyethylene chain in its molecule, a tertiary amine oxide, a quaternary ammonium 1090fo71 halide, a builder for the non-ionic detergent and a defoaming agent, all as more fully hereinafter described. Although each of the non-ionic detergent, the tertiary amine oxide, and the quaternary ammonium halide used in the invention is known to have detergent or surface-active properties, the invention is based on the unexpected discovery that when used in combination, these ingredients provi~e a detergent effect which is much greater than that achieved by the use of any one or two of those materials at equivalent concentrations.
Although the reason for the result is unknown, it appears that the ingredients have a potentiating or synergistic effect when all three are combined in a hard surface deter-gent composition in accordance with the invention.
The non-ionic detergent used in the invention belongs to a class of compounds formed by condensation of an alkyl p~enol, an alkyl amine, or an aliphatic alcohol with sufficient ethylene oxide to produce a compound having a polyoxyethylene chain within the molecule, i.e., a chain composed of recurring (-0-CH2-CH2-) groups. Many compounds of this type are known and used for their detergent, surface active, wetting and emulsifying properties. The detergents of this type which can be used in the invention are those produced by the condensation of about 5-30, and preferably about 8-16, moles of ethylene oxide with 1 mole of (1) an alkyl phenol having about 1-15, and preferably 7-10, carbon atoms in the alkyl group; (2) an alkyl amine having about 10-20, and preferably 12-16, carbon atoms in the alkyl group; and (3) an aliphatic alcohol having about 10-20, and preferably 12-16, carbon atoms in its molecule. The number - 1090~7~
of moles of ethylene oxide which are condensed with 1 mole of parent compound (i~e., the alkyl phenol, the alkyl amine, or the aliphatic alcohol) depends on the molecular weight of the hydrophobic portion of the condensation product. The nonionic detergent used in the invention should have sufficient ethylene oxide units to insure solubility thereof in the detergent composition or in any dilution thereof which may be used in practice. In general, the nonionic detergents suitable for use in the invention can be formed by condensing the reactants in the proportions given above.
The alkyl phenols which can be condensed with ethylene oxide to give a nonionic detergent useful in the invention are those in which the alkyl group contains about 1-15, and preferably about 7-10, carbon atoms in a straight or branched chain, which can be saturated or unsaturated.
Particularly preferred nonionic detergents of this type comprise the condensation products of 1 mole of octyl phenol condensed with about 10 moles of ethylene oxide. Examples of other suitable alkyl phenol-ethylene oxide condensation products are those in which the hydrophobic portion of the product is derived from phenol, methyl phenol (cresol), ethyl phenol, hexylphenol,decylphenol, dodecylphenol, and the like~
The other nonionic detergents which can be used in the invent~on are those wherein an alkyl amlne or aliphatic alcohol, in which the alkyl group in each case has about 10-20, and prefera~ly about 12-16, carbon atoms in a strai~ht or branched chain which can be saturated or unsaturated, is condensed with about 5-30, and preferably about 8-16, moles of ethylene oxide. Examples of such compounds are the condensation products of ethylene oxide with decylamine, dodecylamine, tridecylamine, hexadecylamine, octadecylamine, and the like; and with decyl alcohol, dodecyl alcohol, tridecyl alcohol, hexadecyl alcohol, octadecyl alcohol and the like.
The second ingredient in the synergistic combination of surface active agents used in the invention is a tertiary amine oxide, specifically an alkyl di (lower alkyl) amine oxide in which the alkyl group has about 10-20, and preferably 12-16, carbon atoms, and can be straight or branched chain, saturated or unsaturated. Examples of suitable tertiary amine oxides useful in the invention include lauryl dimethyl amine oxide, myristyl dimethyl amine oxide, and those in which the alkyl group is a mixture of different chain lengths, such as lauryl/myristyl dimethyl amine oxide, dimethyl cocoamine oxide, dimethyl ~hydrogenated tallow) amine oxide, and myristyl~palmityl dimethyl amine oxide.
The third ingredient in the synergistic combination of surface active agents used in the invention, is a quaternary ammonium halide surfactant having the formula Rl - N - R4 X
where Rl and R2 are lower ~i.e., Cl-C73 alkyl, and preferably ~ethyl groups; R3is an alkyl or phenyl-substituted alkyl group having about 1-18, and preferably a~out 1-12 carbon atoms; R4 is an alkyl or phenyl-substituted alkyl group having a~out 10-20, and preferably 12-18, carbon atoms; and ~090~i71 X is a halogen, preferably chlorine. Examples of suita~le quaternary ammonium halide surfactants include dioctyl dimethyl ammonium chloride, octyl decyl dimethyl ammonium chloride, didecyl dimethyl ammonium chloride, (Cl2-C18) n-alkyl dimethyl benzyl ammonium chloride, (Cl2-Cl4) n-alkyl dimethyl ethylbenzyl ammonium chloride, and dimethyl (difatty) ammonium chloride.
Also incorporated in the detergent composition of the invention are conventional builders commonly known and used in conjunction with synthetic detergents, which function to improve the detergent properties of the composition.
The builders are typically alkaline salts such as the alkali metal carbonates, phosphates, and silicates. In add~tion to improving the detersive properties of the composition, such builders control and maintain the p~ of the bath, modify the adsorption of the detergent on the substrate and/or the soil and act as suspending or peptizing agents. Examples of suitable builders for us in the invention include sodium tripolyphosphate, tetra sodium pyrophosphate, trisodium phosphate, sodium carbonate, sodium orthosilicate, sodium metasilicate and the corresponding potassium salts.
The three main ingredients used in the detergent composition of the in~ention, being surface active agents, have a tendency to generate copious quantities of foam during the use of the detergent composition. The presence of foam is not necessary for the detergent effect produced and in many applications, such as the mechanical or hand-mopping of a floor, foam is undesirable. Accordingly, the composition ~-of the invention comprises a small quantity of an anti-foam agent in an amount sufficient to prevent foaming.
1090~;71 Typically, small concentrations, on the order of 0.001-0.01% by weight of an anti-foam agent can be used. The anti-foam agent can be any conventional type, including those based on silicones (e.g., methyl polysiloxanes) or other water-insoluble oils of low volatility and strong spreading power.
Other anti-foam agents which can be used include glyceride oils, fatty acids, and higher alcohols and glycols.
In particular, the present invention provides a detergent con-centrate composition comprising:
(A) about 1.5-2.0~ by weight of a non-ionic detergent which is a con-densation protuct of about 8-16 les of ethylene oxide with one mole of a compound selected from the group consisting of (1) an alkyl phenol having about 7-10 carbon atoms in the alkyl group;

EXAMPLE I
A preferred detergent concentrate in accordance with the invention has the following composition:
Ingredient Percent by Weight Nonionic detergent (condensation 1.70 product of 1 mole of octyl phenol with 9-13 moles of ethylene oxide) Tertiary amine oxide ~lauryl dimethyl amine oxide) 0.28 Quaternary ammonium surfactant (didecyl dimethyl ammonium chloride) 0.38 Builders sodium metasilicate 2.56 sodium carbonate 1.70 tetrasodium pyrophosphate 1.28 Water 92.10 100.00 The composition is homogeneous, highly stable against phase separation in storage, and can be readily diluted with up to 100 parts of water, or more, to give detergent solutions useful for a wite variety of hard surface cleaning applications. -n L~, 1(~90~;71 EXAMPLE II
The composition of Example I was diluted with water in the ratiG of about 20 parts of water to l part of deter-gent concentrate. About 4 ounces of the diluted solution was placed into a beaker and about 2cc. each of a vegetable oil and a used automobile crank case oil were added. On stirring by hand, the vegetable and mineral oils were emulfi-fied within about 30 seconds, forming a stable honogeneous emulsion with the detergent solution.
l~ For comparison, the above test was repeated using a detergent solution prepared from a commercially available hard surface detergent in which the detergent is primarily -butyl cellosolve. When diluted to give a detergent solution containing an equal concentration of active ingredients, the commercial solution was unable to emulsify ~he add~d vegetable an~ mineral oils. : .-EXAMPLE III
In this ex.ample, there was employed a test pro- .;
cedure recommended by the Chemical Specialties Manufac~ure s Associativn (Tentative Meth~d, revised 3/15/74, "Evaluating ..
the Relative Efficiency of ,~ueous Cleaners on Painted Surfaces"). In the test, glass panels coated with a standard white paint are marked by means of standard test pencils and crayons which are.applied under controlled increasing pressure to the painted surface to form a series of lines.
The detergent to be tested is evaluated for its ability ~o remove or reduce the intensity of the lines on the glass 1090~;71 panels using a Gardner Straightline Washability Apparatus.
The effectiv~ness of a test detergent solution is evaluated against the performance of a standard solution having the following composition:
Sodium carbonate 0.5% by weight Sodium tripolyphosphate0.2%
Butyl cellosolve 5.0%
Nonionic detergent 0.5%
(condensation product of 1 mole of octylphenyl with about 10 moles of ethylene oxide) Water 93.8 ~0 .0~
The detergent concentrate of Example I, diluted to a water content of 93.8% to match the standard solution, was evaluated against the standard. For use, each concentrate was diluted with water in the ratio of 20 parts water per part of concentrate. The results showed that the solution of the invention was more effective in removing or lightening the applied markings. The concentrate of Example 1 achieved a rating of 7 (total removal) for the crayon markings, and a rating of 6 (faint trace of soil remaining) for the pencil markings. By contrast, the standard solution had a ra~ing of 2 (slight decrease in soil) for the crayon markings and a rating of 4 (50% of soil remaining~ for the pencil markings.
