Because of their superior solubility, the short-chain polyacrylates, which have molecular weights of from 1,000 to 10,000 g / mol, and particularly preferably from 1,000 to 5,000 g / mol, may again be preferred from this group.
- copolymeric polycarboxylates in particular those of acrylic acid with methacrylic acid and of acrylic acid or methacrylic acid with maleic acid.
- the polymers may also contain allylsulfonic acids, such as allyloxybenzenesulfonic acid and methallylsulfonic acid, as a monomer.
- liquid detergents preference is given to using soluble builders, such as, for example, citric acid, or acrylic polymers having a molar mass of from 1,000 to 5,000 g / mol.
- soluble builders such as, for example, citric acid, or acrylic polymers having a molar mass of from 1,000 to 5,000 g / mol.

- phosphonates such as HEDP (1-hydroxyethane-1, 1-diphosphonic acid) or DTPMP (diethylene triamine penta (methylene phosphonate)
- Preferred liquid detergents preferably contain water as the main solvent. It is preferred that the detergent more than 5 wt .-%, preferably more than 15 wt .-% and particularly preferably more than 25 wt .-%, each based on the total amount of detergent, water. Particularly preferred liquid detergents contain - based on their weight - 5 to 65 wt .-%, preferably 10 to 60 wt .-%, particularly preferably 25 to 55 wt .-% and in particular 30 to 50 wt .-% water. Alternatively, the liquid detergents may be low-water to water-free detergents, the water content in a preferred embodiment being less than 10% by weight and more preferably less than 8% by weight, based in each case on the total liquid detergent ,
- nonaqueous solvents may be added to the detergent.
- Suitable non-aqueous solvents include mono- or polyhydric alcohols, alkanolamines or glycol ethers, provided that they are miscible with water in the specified concentration range.
- the solvents are preferably selected from ethanol, n-propanol, i-propanol, butanols, glycol, propanediol, butanediol, methylpropanediol, glycerol, diglycol, propyldiglycol, butyldiglycol, hexyleneglycol, ethylene glycol methyl ether, ethylene glycol ethyl ether,

- the detergent contains such an alcohol, in particular 1, 2-propanediol and / or glycerol, in amounts of between 0.5 and 15 wt .-%, based on the total detergent.
- the detergents described herein in particular the described low-water to anhydrous liquid detergents, can be filled into a water-soluble casing and thus be part of a water-soluble packaging. If the detergent is packaged in a water-soluble casing, it is preferred that the content of water is less than 10% by weight, based on the total detergent.
- the thermoforming process generally includes forming a first layer of water-soluble sheet material to form protrusions for receiving a composition therein, filling the composition into the protrusions, covering the composition-filled protrusions with a second layer of water-soluble sheet material, and sealing the first and second layers at least around the bulges.
- the water-soluble coating is preferably formed from a water-soluble film material selected from the group consisting of polymers or polymer blends.
- the wrapper may be formed of one or two or more layers of the water-soluble film material.
- the water-soluble film material of the first layer and the further layers, if present, may be the same or different.
- the water-soluble package comprising the detergent and the water-soluble wrapper may have one or more chambers.
- the liquid detergent may be contained in one or more chambers, if any, of the water-soluble coating.

Suitable dicarboxylic acids are itaconic acid, malonic acid, succinic acid and mixtures thereof, with itaconic acid being preferred. Likewise preferred polyvinyl alcohol copolymers include, in addition to vinyl alcohol, an ethylenically unsaturated carboxylic acid, its salt or its esters. Such polyvinyl alcohol copolymers particularly preferably contain, in addition to vinyl alcohol, acrylic acid, methacrylic acid, acrylates, methacrylates or mixtures thereof.

- Another object of the invention is a process for the cleaning of textiles, which is characterized in that in at least one process step, an inventive composition is used and the use of a liquid detergent according to the invention for washing textiles.
- Methods for cleaning textiles are generally distinguished by the fact that various cleaning-active substances are applied to the items to be cleaned and washed off after the contact time, or that the items to be cleaned are otherwise treated with a detergent or a solution or dilution of this product. All conceivable washing methods can be enriched in at least one of the method steps to the application of a detergent according to the invention and then represent embodiments of the present invention. All facts, objects and embodiments described for means according to the invention are also applicable to this subject of the invention. Therefore, reference is made at this point expressly to the disclosure in the appropriate place with the statement that this disclosure also applies to the above inventive methods and uses. Examples
