Examples are sorbic acid and its salts, benzoic acid and its salts, salicylic acid and its salts, phenoxyethanol, formic acid and its salts, 3-iodo-2-propynylbutylcarbamate, sodium N- (hydroxymethyl) -glycinate, biphenyl-2-ol and mixtures from that. Further suitable preservatives are isothiazolones, mixtures of isothiazolones and mixtures of isothiazolones with other compounds, for example tetramethylolglycoluril.
- the active agent-containing gel is preferably arranged between two protruding, water-insoluble layers.
- the two water-insoluble layers are connected to each other at the edges in a water vapor-tight manner.
- the sandwich-like, between the water-insoluble layers enclosed drug-containing gel is thus largely protected from the ingress of water vapor.
- the connection of the edges of the at least two water-insoluble layers can be done for example by means of sealing, welding or gluing.
- the textile pretreatment agent comprises two water-insoluble layers. They can, for example, consist of two water-insoluble foils or only one water-soluble be formed soluble film. In the latter case, the film is kinked in the middle, so that in each case three open, with the opposite, water-insoluble layer to be joined edges.
- the water-insoluble films must have a suitable water vapor tightness. This is achieved for example by means of polyolefin film with a suitable thickness. Suitable films include, for example, polyethylene and / or polypropylene. The thickness of the water-insoluble films is preferably between 5 and 100 microns.
- the water-insoluble films used have a layer structure.
- the water-insoluble films preferably have at least one layer of a polyolefin.
- the water-insoluble films expediently have a sealing layer.
- the sealant layer may be formed by a fusible, sealable material such as polyethylene or a heat and / or pressure sensitive sealer.
- the water-insoluble films may have a barrier layer that protects the drug-containing gel from the ingress of water vapor, but also protects sensitive and / or volatile constituents of the drug-containing gel from decomposition and / or evaporation.

- a first water-insoluble film is heated and deep-drawn by means of a vacuum.
- the drug-containing gel is filled and then a second water-insoluble film is attached by means of sealing over it.
- This embodiment is particularly suitable when using active ingredient-containing gels, which have not yet reached their final strength after production.
- the application of the drug-containing gel to a stain occurs by peeling the two interconnected water-insoluble layers apart, to facilitate the user, a tear tab or indentation may be present on the fabric pretreatment agent Another possibility is to avoid defined zones of water-insoluble layers during sealing, welding or bonding. In the case where the two water-insoluble layers are formed from a water-soluble film, the user can easily unfold the two interconnected layers and place on the side where the active agent-containing gel is on the stain.
- the user completely pulls apart the two water-insoluble films.
- the active ingredient-containing gel will adhere more strongly to one of the two water-insoluble film. In this case it is a statistical question on which of the two water-insoluble films, the drug-containing gel remains. In this embodiment, however, it is essential that the active agent-containing gel has a minimum strength and does not split when the two water-insoluble films are pulled apart.
- the two water-insoluble films are different. It is preferred that the surfaces which face the active agent-containing gel at least partially differ from the two water-insoluble layers. This distinction causes a stronger adhesion of the active ingredient-containing gel to one of the two water-insoluble films.
- the different strong adhesion can be achieved by various methods.
- an adhesive layer for example, an acrylate dispersion can be applied.
- the adhesion of the active substance-containing gel can also be achieved by changing the surface of a water-insoluble film facing the active substance-containing gel by means of a plasma treatment, a flame treatment and / or a corona treatment. In this case, the wetting and thus the adhesion of the active ingredient-containing gel on the surface of the treated water-insoluble film is increased.
- the adhesion of the drug-containing gel to this water-insoluble film can be reduced, and after the water-insoluble layers are pulled apart, the drug-containing gel remains on the uncoated, water-insoluble film.
- a water-insoluble layer remains with the active ingredient-containing gel.
- the active ingredient-containing gel is brought into direct contact with a stain on a textile fabric.
- a slight contact pressure or a small lateral movement during pressing by the user can be used. Since the active substance-containing gel adheres more strongly to the textile fabric than to the water-insoluble layer, for example owing to the roughness and absorbency of the textile fabric or through adhesives incorporated in the active ingredient-containing gel, the water-insoluble layer can be stripped off in such a way that the active ingredient containing gel remains on the stained fabric.
- the stained fabric can be placed in a container for the storage of dirty laundry and stored there until the actual laundry.
- the active ingredient of the active ingredient-containing gel is preferably a surfactant, more preferably a liquid nonionic surfactant.
- the textile pretreatment agents of the present invention can be used to remove, minimize and / or solubilize stains on a fabric.
- a water-insoluble film with a layer structure of 20 ⁇ m polyethylene (sealing layer) / 10 ⁇ m aluminum / 20 ⁇ m oriented polypropylene was deep-drawn under vacuum at 100 mbar and 210 ° C. with a holding time of 3 seconds.
- the resulting recess had the dimensions 30 x 20 x 3 mm and on.
- the well was filled to 3 A with the solution prepared above and then overcoated with an aqueous solution of 3 wt .-% CaCl 2 x 2H 2 O.
- a second water-insoluble film with a layer structure of 20 ⁇ m oriented polypropylene / 10 ⁇ m aluminum / 20 ⁇ m polyethylene (sealing layer) was attached by means of sealing over it.
- a solution 1 comprising 2% by weight of sodium alginate in demineralized water and a solution 2 comprising 36% by weight of 1,2-propylene glycol, 11% by weight of Ci 2 -C 4 -ROH with 5 EO and 4 PO, 53 wt .-% Ci 2 -Ci 8 -ROH prepared with 7 EO. 2.13% by weight, based on the total solution 2, of sodium citrate were added to this solution and dispersed.
- the two water-impermeable films of the textile pretreatment agent according to Example 1 were pulled apart, wherein the active ingredient-containing gel completely adhered to one of the two water-insoluble film.
- the active ingredient-containing gel was placed on the test stains with the aid of the water-insoluble film attached to it and left overnight on the tissues (exposure time: about 12 hours). Subsequently, the test fabrics, without removing the active ingredient-containing gels thereon, in a washing machine in 40 ° C standard program (2 commercially available Persil tabs as a detergent, 3.5 kg of washing) washed. For reference, a test fabric without pretreatment was washed in each case.
- test fabrics were measured before and after the wash by means of spectrophotometric remission measurements in the L-a-b system to the brightness value L (in%).
- the remission measurements were carried out on 3 randomly selected sites on the tissue each with 3-fold determination per measurement point.
- all tissue lobules were ironed and dried under the same conditions. From the 9 measured values per measurement thus obtained, an average L value before washing and an average L value after washing were obtained. From the difference between these values, the difference value ⁇ L (L value after - L value before) was determined:
