Title of the invention

Improved detergent and cleaner combination

Anwendungsgebi et the invention

The invention relates to improved detergents and cleaners which are obtained by combination of surface-active compounds.

Characteristics of the known technical solutions

Generally, it is known that by combination of surface-active compounds, such as anionic or non-ionic compounds, vaporizing and cleaning agents having different performance characteristics are obtained. Depending on the field of application, detergents and cleaners with certain performance properties are developed. So the problem of foam control of detergents and cleaners for the application of detergent and cleaning agent combinations z. B. in washing machines or dishwashers of great importance.

Thus, combinations of nonionic and / or iono -genen compounds are known, which in addition to a good Waschbzw. If sufficient wetting power is sufficient, the cleaning ability is insufficient. Detergents of low-foaming v / ash raw materials of the class of the polyethylene glycol ether derivatives of fatty alcohols, fatty acids and alkylphenols and water-soluble polyethylene oxide adducts on polypropylene glycols and other polypropylene glycols are known (DE-AS 1692016, DE-AS 1692017).

 Uichtionogenic surfactants, especially the fatty alcohol and

Alkylphenoloxethylates have long been proven in use in detergents and cleaners. The known mixtures of nonionic surfactants are based on combining the good properties of individual surface-active adducts with one another and further improving them in certain properties (DE-AS H67637, DE-AS H67638). Due to the good biodegradation ethoxylated primary and secondary alcohols are preferably used in detergents and cleaners. These nonionics are wetting agents that remove extremely greasy soiling. The tendency of the compounds to foaming is unfavorable when used as detergents and cleaners in dishwashers and washing machines. In DE-AS I6I7065 detergents are described which. are characterized by a content of ethylene oxide, propylene oxide and / or ethylene oxide-propylene oxide adducts of higher fatty alcohols.

For the production of low-foaming dishwashing detergents and cleaners, inter alia ethoxylates of low ethylene oxide or propylene oxide adducts (DE-OS 1807779) are used for foam damping and for achieving a stain-free, glossy dishware. Furthermore, DE-OS 2825218 discloses detergents which contain surfactants in the form of alcohols alkoxylated with ethylene oxide and / or propylene oxide. The products have the function of surfactants or they set the pour point of the detergent down. Strongly alkaline dishwashing detergents and cleaning agents, preferably bottles detergents are characterized by a content of foam-suppressing addition compounds of ethylene oxide and / or propylene oxide, which in a 1% aqueous solution has a cloud point of 10 to 60 ⁰ G ascending

point. In this case, adducts of ethylene oxide to hydrophobic components and addition products of propylene oxide to hydrophilic components are used (1261618). As literature and practice show, propylene oxide adducts of alcohols are not basically miscible with water and they have only a slight cleaning action. In combination with other surface-active products, they have proven to be effective as foam-inhibiting or pour point-lowering agents, preferably in dishwashing detergents.

The known detergent and cleaning agent combinations based on propylene oxide adducts and higher fatty alcohols generally have a sufficient wetting power, low foaming power and good washing or cleaning properties in a synergistic effect, however, the washing and cleaning action is the washing out of oily soils, such as oily Pigmentverschffiutzungen, tissues are still insufficient when these combinations are used.

Aim of the invention;

The object of the invention is to improve detergents and cleaners in such a way that, compared with the known detergents and cleaners, they generally remove oily soils, preferably oil-containing pigment compounds or pigment soils, to a great extent or completely from the fabric and at the same time increase them Wetting power and have a low tendency to foam in the aqueous phase.

Explanation of the essence of the invention

- The technical task '

The invention has for its object to develop an improved detergent and cleaner combination with high washing activity by mixing non-ionic or ionogenic and non-ionic surface-active compounds according to the objective.

Features of the invention

The technical problem is solved according to the invention by mixing nonionic surfactants known per se with one another or ionogenic and nonionic surfactants with one another and the washing and cleaning agent combination

A) 4 to 50 wt .-%, preferably 8 to 25 wt .-%, surfactants or mixtures of surfactants of the following structure

can be, and

B) 96 to 50 wt .-%, preferably 92 to 75 wt .-%, .. ^ nichtioijogenen and / or anionic surfactants alone or in a mixture.

Suitable compounds of component A are preferably propoxylated adducts of alcohols, diols, hydroxy ethers and triamines.

As component B are preferably

Alkylphenol polyglycol ethers: Co-C-p-alkyl radical,

6-20 ethylene oxide units

Alkyl polyglycol ethers: C.sub.-C.sub.p-alkyl, preferably

Cg-C ₁₈ , 5 to 30 ethylene oxide units, preferably 8 to 20,

Fatty aminoxethylates: C ₁ pC ₂ Q-alkyl radical, preferably

C ₁₆ -C ₁₈ , 3 to 30 ethylene oxide units, preferably 6 to 20

and alkyl ether sulfates _e

The washing and cleaning agent combination of components A and B according to the invention is superior in its washing activity to the known ionic or nonionic surfactants. This is surprising, since the compounds of component A in water are difficult to insoluble and have only a certain cleaning effect. The combination according to the invention is particularly advantageous for the removal of fabric contamination or soiling of other substrates or substrates caused by oils and / or pigments. Due to the improved wetting power and the high detergency of the detergent combination according to the invention, a high washing effect can be achieved by selective choice of components A and B, wherein the contaminants are removed in a short time to completion. The foaming behavior of the components B can also be regulated by appropriate dosage of A and adapted to the requirements. The reduction of foaming, especially at elevated temperature, is of great economic importance, since a number of Wajschmitteln due to their high foaming power in the entire temperature range up to 100 ⁰ C industrial or in household machines can not be used.

Execution examples

The following examples are not intended to limit the scope of the invention claim, but represent only a selection of the plurality of tested mixtures. The Tauchnetzvercib'gen the products was determined by Fischhakenmethode means test pieces of cotton body and as TIV 100 (g amount used for 100 Netzsekunden ). The washing power of the products was at 50 ⁰ C with

a tar applied to wool tar mineral oil soiling (TlIW) tested in a ram washing machine. In this case, the sample is moved up and down in a perforated basket about 90 times a minute in the liquor bath. The assessment is done visually separately after washed out pigment (P grade 0-5) and fat content (F grade 0-5), where 0 corresponds to 100% leaching capacity. Concentration of WHAT: 3 g / l

 The foamability was measured according to DIN 53902 at a concentration of 1 g WAS / 1

 The values listed in the table show the broad applicability of the modification according to the invention of washing raw materials and other specialty surfactants with compounds of component A.

In particular, the pigment washout and TFV 100 values of the blends are significantly improved. Examples 1, 5, 7, 10, 12, 14, 16 and 18 are included for comparison to illustrate the effect of the surfactants of component A contained in the remaining examples.

In many cases, in the compositions of the invention, a desirable reduction in foamability occurs, especially at higher temperatures. The water solubility of the mixtures is improved by suppression of the gel phase over pure nonionic surfactants.
