Foam formation was observed for all four products during the wash. The amount of foam found was indicated by a number on a numerical scale from 0 to 5 obtained was made by cutting the round glass of the washing machine door along the vertical diameter in five divided equal parts or units. A higher numerical value means a higher foam level, a value of about 2.5 units being the maximum foam level recommended for this type of washing machine represents. The following table with its explanations illustrates the unique synergistic effect, which was achieved by combining the nonionic detergent substances with the fatty acid mixture.

Amount of product used in g
Foam units | 2 ¹ Z ₂ foam units

A (no antifoam agent)

B (antifoam agent containing acyl groups)

C (non-ionic anti-foam agent)

D (Combined anti-foam agent made from acyl group-containing and non-ionic components)

42 = 7 more than A.

56 = 21 more than A.

91 = 56 more than A.

63 = 14 more than A.

77 = 28 more than A.

154 = 105 more than A.

From the above values it can be seen that the amount of detergent according to the invention, which is still desired foaming can be used in a drum washing machine is much greater than the amount that from those with the acyl group-containing antifoam alone or with the nonionic antifoam foresee values obtained only Hess.

It turns out that when using a detergent based on anionic detergent substance which did not contain any antifoam agent, ^{a maximum of 49 g detergent could be used while maintaining a foam level of 2 ×} / ₂ units (the maximum recommended when using a drum washing machine). When 5% acyl-containing antifoam was added to the composition of Product A, the amount of detergent that could be used without exceeding the stated maximum foam level was 63 g. This means that the addition of the antifoam containing acyl groups made it possible to reuse 14 g of detergent without exceeding the specified maximum foam level.

If 4% nonionic detergent is used in place of 4% of the alkylbenzenesulfonate from Product A was, the amount of Product can be increased to 77 g. That is, the use of the nonionic detergent substance made possible an additional use of 28 g.

If the composition of the detergent is modified in such a way as in the product D according to the invention was found to be both 5% of the acyl-containing antifoam as well as 4% non-ionic detergent substance, 154 g of detergent could be used can be used without exceeding the specified maximum foam level. This means, by combining the nonionic and the acyl group-containing component in the detergent allows an additional use of 105 g of product. When the effects of the acyl group-containing antifoam and the nonionic components add up exactly, so it would have to be expected that one Re-use of only 42 g would be made possible. Unexpectedly, however, the 105 g allows, so that a maximum cleaning effect is achieved with the anionic detergent substance without exceeding the specified maximum foam level.

The synergistic effect of the acyl group-containing antifoam and the nonionic components at detergent concentrations which result in a foam level of only I ¹ Z ₂ units can also be seen from the table above.

A particular advantage of the use of the anti-The nonionic constituents, which according to the invention

Foaming agent of the invention is that a further preparation with the fatty acids and / or soaps of the previous area of fatty acid mixtures than have previously been used together as an anti- lying invention, foaming agents can be used proposed for the preparation of nen generally be defined as compounds that Detergents with low foaming at a strong 5 due to condensation of (by their nature hydrophilic) Detergent action based on synthetic an-alkylene oxide groups with an organic hydrophobic one Ionic detergent substances used are compounds that are aliphatic or alkyl aromatic can. However, the already suggested fatty acid can be manufactured. The length of the hydrophilic or mixtures for the compositions of the present polyoxyalkylene radical, which are condensed with a Invention insofar as the synergistic io specific hydrophobic group is required Effect in terms of foam suppression can easily be selected by the person skilled in the art so that a in the case of mixtures of non-ionic components with the water-soluble compound with a certain heterogenous Mixtures of acyl group-containing compounds of hydrophilic to hydrophobic elements fertilizing is observed. Mixtures of is obtained in this way.

At least three high molecular weight compounds with 15 such compounds are used, for example, by acyl groups and different content of carbon condensation of ethylene oxide with a hydrophobic atom, provided that the Ge base, which is obtained by condensation of propylene oxide with mixed at least 50% of such compounds with Propylene glycol is formed. That molecular contains at least 16 carbon atoms. The presence of at least 5% of those of the order of 1500 to 1800 is beneficial in weight of the hydrophobic portion of the molecule. The addition of compounds with at least 20 carbon atoms. of polyoxyethylene residues on this hydrophobic portion The presence of other acyl group-containing compounds increases the water solubility of the molecule as a whole, fertilize in relatively small amounts, such as saturated up to a content of about 50 percent by weight, the C ₁₂ - and C ₁₄ -acids and unsaturated C ₁₈ -fatty acid based on the total condensation product, an (oleic or linoleic acid), is not disadvantageous and liquid products can even be obtained in polyoxyethylene. If it is advantageous, provided that the mixture further increases the content of polyoxyethylene in the rest of at least 50% saturated acyl group ratio to the hydrophobic portion, the end-containing compounds with 16 or more carbon product becomes waxy or solid.

Combinations of both methods can also be used can be applied. Compositions in liquid dispersion can also be prepared.

The detergents whose foaming power can be reduced according to the present invention, include those disclosed in U.S. Patents 2,486,921 and

2,486,922. The active ingredient in these detergents is a synthetic anionic sulfate or sulfonate and an alkali tripolyphosphate. The ratio of tripolyphosphate to the sum of synthetic detergent substances and non-ionic compounds is available for the compositions of the present invention preferably in a range of about 2: 1 to about 6: 1, and excellent properties are achieved at a ratio between about 3: 1 and 4: 1.

The anionic synthetic detergent substances are water-soluble salts of organic sulfuric acid reaction products, which is an alkyl radical having about 8 to about 18 carbon atoms and a sulfonic acid or Contain sulfuric acid ester residue. Examples of these synthetic anionic constituents of detergents of the present invention are the sodium or potassium alkyl sulfates, such as in particular those which by sulfating higher alcohols obtained by reducing glycerides of sebum and coconut oil will be made; Sodium and potassium alkyl benzene sulfonates, such as particularly those in the U.S. patents 2,220,099 and 2,477,383 in which the alkyl groups have from about 9 to about 15 carbon atoms contain; Sodium alkyl glyceryl ether sulfonates, such as, in particular, the ethers of high molecular weight Alcohols made from tallow and coconut oil; Sodium Coconut Oil Fatty Acid Monoglyceride Sulphates and sulfonates; Sodium salts of sulfuric acid esters of the reaction product of 1 mole of a high molecular weight fatty alcohol such as for example tallow or coconut oil alcohol, and about

3 moles of ethylene oxide. Detergents made from such water-soluble synthetic salts and mixtures thereof containing from about 10 to about 50% active anionic synthetic Substances together with alkali pyrophosphate, tripolyphosphate or other higher polyphosphates in the Contain the proportions given above, are particularly suitable for the purpose of the present Invention. Other materials such as water, coloring substances, fluorescent dyes, perfume, carboxymethyl cellulose, sodium sulfate, silicate, sodium carbonate and others alkaline salts as well as other materials known as constituents of detergents may be present.

The amount of fatty acid mixture used for the detergents of the present invention is between 1 and 10% fatty acid mixture or soap, calculated as fatty acid and based on the total Product.

The amount of non-ionic ingredients is usually between 1 and 10% based on the entire product. Both the fatty acid mixture and the nonionic constituents are preferred in an amount of, based on the total composition, each 1 to 10% and with advantage of 2 to 5% used. In more general terms: the ratio of both the acyl group-containing component (as fatty acid) as well as the nonionic constituents can become detergent anionic synthetic substance vary between 0.1: 1 and 1: 1.

The present invention is to be explained in more detail below on the basis of examples. Refer to parts focus on the weight.

For the detergents of the above examples, alkylbenzenesulfonates were used as synthetic detergent substances with 9 to 15 carbon atoms and an average of about 12 carbon atoms in the alkyl radical and / or alkyl sulfates, which were produced by sulfating higher alcohols obtained by reducing sebum. It can also be used other than the synthetic detergent sulfates or sulfonates alone or used in mixtures. Fatty acids used as antifoam agents can also be used or the corresponding alkali soaps can be used for each of these fatty acids.

The antifoam agent of the invention can also be used in detergents other than those described above Detergents are used. For example, it has been found that agents for automatic dishwashing machines the addition of a small amount of synthetic anionic cleaning-active substance is advantageous affects the formation of stains and films. However, even if they are used, less will arise Amounts of such substances in the case of those occurring during the operation of a dishwasher Violent movements Difficulty caused by the foam that forms. With the antifoam agents described here can be caused by the presence of such detergent synthetic anionic substances Foaming can be effectively suppressed.
