Abstract

The present invention relates to a washing, cleaning or pretreatment agent for textiles. It has surprisingly been found that, through the use of certain fatty acid esters in conjunction with at least one surfactant, a smoother textile surface effected on the e.g. an iron easily slides.

Description

The present invention relates to a washing, cleaning or pretreatment agent for, inter alia, textiles. Surprisingly, it has been found that by using certain fatty acid oligoesters in combination with at least one surfactant, the frictional resistance of the textile surface can be reduced. Thus, said fatty acid oligoester acts as an ironing aid facilitating the guidance of the iron over the textile surface.

To clean heavily soiled laundry, high temperatures of 60 ° C or more are often required. While such temperatures are possible for the cleaning of bed or table linen or similar durable materials, garments in particular are often made of such materials that can only be washed at a temperature of about 30 ° C or 40 ° C. This applies in particular to so-called "easy-care" textiles and garments, which are often referred to as, for example, "easy-care", "non-iron", etc., and are marketed and increase in importance in the market. The realization of such properties dictates that Easy-Care products are mostly made from synthetic fibers and thus can only be washed at low temperatures such as 30 ° C or 40 ° C.

Such low cleaning temperatures are also increasingly finding the approval of consumers. In order to allow the most environmentally friendly cleaning, garments are washed at ever lower temperatures. This creates a power savings. From the manufacturer's point of view, the setting for washing programs is often chosen so that a lower temperature prevails during the wash cycle with a view to environmentally friendly cleaning of clothing. In addition, water consumption is significantly lower in modern machines than in older models.

Despite reduced temperature and despite water savings, a thorough cleaning must still be achieved even under the changed washing conditions. In addition, with regard to the cleaning of textiles, consumer expectations have even increased. Even white textiles should not gray or yellow after several washes, colored textiles should retain their color and the fabric should be spared; At the same time, all types of soiling are to be removed even at low temperatures.

With regard to a more environmentally friendly washing, consumers are increasingly paying attention to the composition of the detergents. These should have as few polluting components as possible.

In addition, the fabric on the surface is changed by increasing washing. This is particularly noticeable during the ironing process, since on the surface of a correspondingly often washed textile, the iron can often only be moved during the ironing process with increased effort. The iron slides worse.

There is therefore a need for detergents, in particular for liquid detergents which, even after several washes, make it easier to slide an iron on the textile surface and thereby reduce the effort required in ironing in comparison to conventional detergents. Surprisingly, it has been found that when using certain fatty acid oligoester washing, cleaning or pretreatment can be provided which reduce the frictional resistance of the textile surface and thus reduce the effort during ironing.

These include in particular the solid preparations obtained by granulation, extrusion or lyophilization, advantageously as concentrated as possible, low in water and / or added with stabilizers. In an alternative dosage form, the enzymes may also be encapsulated, for example by spray drying or extrusion of the enzyme solution together with a preferably natural polymer or in the form of capsules, for example those in which the enzymes are entrapped as in a solidified gel, or in such Core-shell type in which an enzyme-containing core is coated with a water, air and / or chemical impermeable protective layer. In deposited layers, further active ingredients, for example stabilizers, emulsifiers, pigments, bleaches or dyes, may additionally be applied. Such capsules are applied by methods known per se, for example by shaking or rolling granulation or in fluid-bed processes.

Biol. Chem. 177, 751-766, 1948 ).

The washing, cleaning or pretreatment agent according to the invention may contain, in addition to or instead of the cellulase, other enzymes known in the art or mixtures of enzymes.

The amount of enzyme or of the enzymes is preferably 0.01 to 10 wt .-%, preferably 0.12 to about 3 wt .-%, based on the total washing, cleaning or pretreatment agent. The enzymes are preferably used as enzyme liquid formulation (s).

If the washing, cleaning or pretreatment agent according to the invention is liquid, it preferably has a yield point. The yield stress refers to the smallest stress (force per area) above which a plastic substance behaves rheologically like a liquid. It is therefore given in Pascal (Pa). The yield strength of the composition according to the invention is in particular in the range from 0.1 to 1.0 Pa, preferably in the range from 0.2 to 0.9 Pa, in particular in the range from 0.3 to 0.8 Pa, at 25 ° C. The yield point is determined according to the invention by measurement with a rheometer, in particular with an AR 1000-N rheometer from Texas Instruments, at a temperature of 25 ° C. The rheometer AR 1000-N is an absolute measuring rheometer. In addition, the measured values output by the AR 1000-N rheometer are corrected with appropriate correction factors depending on the measuring geometries used, so that the AR 1000-N rheometer used determines reliable and reliable absolute measured values independent of the measuring geometry.

A liquid washing, cleaning or pretreatment agent according to the invention may contain, as an additional ingredient, in particular if it has a yield point, dispersed particles whose diameter along their greatest spatial extent is preferably 1 to 2000 μm. For the purposes of this invention, particles may be capsules, abrasives as well as powders, granules or compounds of compounds which are insoluble in the washing, cleaning or pretreatment agent, with capsules being preferred.

The term "capsule" on the one hand understood aggregates with a core-shell structure and on the other hand aggregates with a matrix. Core-shell capsules contain at least one solid or liquid core which is enclosed by at least one continuous shell, in particular a shell of polymer (s).

Inside the capsules, sensitive, chemically or physically incompatible as well as volatile components (= active substances) of the liquid washing, cleaning or pretreatment agent can be enclosed stable in storage and transport. In the capsules, for example, optical brighteners, surfactants, complexing agents, dyes and fragrances, antioxidants, builders, enzymes, enzyme stabilizers, antimicrobial agents, Graying inhibitors, anti redeposition agents, pH adjusters, electrolytes, detergency boosters, vitamins, proteins, foam inhibitors, and UV absorbers. The fillings of the capsules may be solids or liquids in the form of solutions or emulsions or suspensions.

The capsules may have any shape in the production-related framework, but they are preferably approximately spherical. Their diameter along their greatest spatial extent may be between 1 μm and 2000 μm, depending on the components contained within and their application.

Alternatively, it is also possible to use particles which have no core-shell structure but in which the active substance is distributed in a matrix of a matrix-forming material. Such particles are also referred to as "matrix particles".

The matrix formation in these materials is, for example, via gelation, polyanion-polycation interactions or polyelectrolyte-metal ion interactions and is well known in the art as well as the production of particles with these matrix-forming materials. An exemplary matrix-forming material is alginate. For producing alginate-based particles is an aqueous alginate solution which also contains the active agent to be entrapped or the entrapped active ingredients, dripped and subsequently cured ³⁺ ions precipitation bath containing ions in a Ca ²⁺ or Al. Alternatively, other, matrix-forming materials can be used instead of alginate.

The capsules can be stably dispersed in the liquid washing, cleaning or pretreatment agents. Stable means that the detergents, cleaners or pretreatment agents are stable at room temperature for a period of at least 4 weeks, preferably at least 6 weeks, without the particles creaming or sedimenting in the composition.

The release of the active ingredients from the capsules is usually carried out by destruction of the shell or the matrix due to mechanical, thermal, chemical or enzymatic action.

When liquid, the washing, cleaning or pretreatment agents in a preferred embodiment contain capsules in which one or more fragrances are included.

When the washing, cleaning or pretreatment agents according to the invention are liquid, they preferably contain water as the main solvent. In addition, nonaqueous solvents can be added to the washing, cleaning or pretreatment agent.

However, it is preferred that the washing, cleaning or pretreatment agent contains an alcohol, in particular ethanol and / or glycerol, in amounts of between 0.5 and 5% by weight, based on the total washing, cleaning or pretreatment agent.

The washing, cleaning or pretreatment agent according to the invention can be provided in prefabricated containers (pouches). As a result, active ingredients can be packaged separately from each other. Furthermore, the dosage for a washing or cleaning or pretreatment course is optimal. In order that the detergents and / or cleaning agents and / or pretreatment agents then also come into effective contact with the objects to be cleaned, the respective containers must be water-soluble.

Preferably, the containers comprise at least one water-soluble material. Preferably, they consist of a water-soluble material. Water-soluble in the sense of the present invention means that the material dissolves in water or dispersed therein.
The water-soluble or water-dispersible material may comprise a polymer, a copolymer or mixtures thereof.

For example, the respective Fatty acids, the mono- or polyols contained in the hydrocarbon skeleton, as well as mono- or polyols containing the desired EO and / or PO structural fragment, are reacted with each other. Alternatively, the fatty acid oligoesters of the present invention may preferably be obtained by alkoxylating the fatty acid esters with mono- or polyols containing the desired EO and / or PO structural fragment.

The preparation of the washing, cleaning or pretreatment agent according to the invention is carried out by means of customary and known methods and processes.

These may include natural and / or synthetic fibers such as silk, linen, cotton, polyester, polyamide or acetate fibers. The fibers can be treated or untreated. Furthermore, such textile fabrics are comprised, which consist of woven or non-woven materials such as felts or nonwovens. An outstanding effect was found on textiles containing cotton.

It has been found that the use of the washing, cleaning or pretreatment agent of the present invention results in a smoother surface of the treated textiles as compared to the surface of textiles treated with detergents, cleaning or pretreatment agents which do not have fatty acid oligoesters of the invention ,

In the context of the present invention, all of the abovementioned embodiments or preferred embodiments or the features described in each case can also be combined individually.

In the following exemplary embodiment, the washing, cleaning or pretreatment agent according to the invention is explained by way of example.

Examples:

Unless otherwise specified, all processes and parameter measurements have been performed at room temperature (20 to 25 ° C).

The recipes below were prepared, in which the influence of fatty acid oligoesters was investigated as ironing relief. <u> Example 1: Composition of Detergents </ u> Example formulation 1 [% by weight] Example recipe 2 [% by weight] water ad 100 ad 100 boric acid 0.5 0.5 citric acid 0.2 0.2 fatty acid oligoester - 1.0 sodium chloride 1.8 1.8 C _10-13 alkyl benzene sulfonic acid, C _12-14 fatty alcohol ether sulfate) in the weight ratio 1: 1 5.7 5.7 Nonionic surfactant (C12-18 fatty alcohol ether) 3.3 3.3 Palm kernel oil fatty acid 0.5 0.5 NaOH 0.6 0.6 Diethylenetriamine penta (methylene phosphonic acid), hepta sodium salt 0.2 0.2 foam breaker 0.04 0.04 Enzymes (amylase, protease, cellulase, mannanase, lipase) 0.4 0.4 Perfume 1.3 1.3 dye 0,002 0,002

The fatty acid oligoester used was Arlypon® TT from BASF. Arlypon® TT is known from the literature as a thickener in shampoos, shower gels and bath foams, which combines both associative and micellar thickening.

The pH of the compositions according to the invention (formulations 1 and 2) was 8.3.

Example 2: Determination of the force required for ironing by measuring the frictional resistance

Different white fabrics (WFK 10A and WFK 20A) were washed and dried five times in a Miele Washing Machine Type 318 at 16 ° d and 40 ° C in the program "Easy Care". The tissues are commercially available from "wfk Testgewebe GmbH". WFK 10 A fabric is made by "wfk Testgewebe GmbH" as "Standard Cotton" (standard cotton) and WFK 20A as "Polyester / Cotton (65% / 35%)" (polyester / cotton 65% / 35%).

To measure the frictional resistance, a device Zwick Z010 was used and determined with the help of the resistance, which opposes a textile surface of a frictional stress by a friction body. test conditions: Sample width: 100 mm Sample length: 250 mm Test length (friction path): 100 mm Weight of the friction body: 175 g Material of the friction body: Teflon Dimensions of the friction body: 71 mm x 56 mm (bearing surface on sample) Test speed: 300 mm / min Test direction: horizontal

The teflon body was centered at the end of a sample so that it rests completely on the sample. By starting the tensile tester, the rubbing body was moved horizontally to the other end of the test sample. During the way the applied force was measured and a force / length change diagram was taken. The less force needed to move the friction body over the fabric, the smoother the surface of the fabric.

The following results each represent an average of 6 measurements. recipes Friction resistance on WFK 10A fabric [cN] Friction resistance on WFK 20A fabric [cN] before washing 29.4 32.2 Formulation 1 without fatty acid oligoester (comparative example) 39.5 36.3 Formulation 2 (according to the invention) 31.0 34.5

In all tissues, a reduction in the frictional resistance can be seen when the detergent is used with the fatty acid oligoester according to the invention. This improvement is particularly outstanding on the WFK 10A fabric.
