Definitions
- the present invention relates to a water-soluble container for a washing, cleaning or pretreatment agent, a portioned washing, cleaning or pretreatment agent in a water-soluble container and a method for producing a corresponding water-soluble container.
- Polymers of all kinds play an increasingly important role in modern detergents. These are often polymers that increase the cleaning performance of a detergent or that contain a care effect. Examples of such agents are soil release polymers, grayness inhibitors, primary detergency boosters, Softener or Antiknitter agents.
- this goal can be achieved, for example, by the use of so-called soil release polymers. These polymers are believed to be deposited on the fabric during the wash cycle. If the textile is subsequently soiled, the polymer is like a protective film between fiber and stain, so that in the subsequent wash the stain can be removed better and easier.
- washing, cleaning or pretreatment agents are nowadays often provided in a suitable amount for a wash load in corresponding containers pre-portioned.
- active ingredients can be packaged separately.
- the dosage for a washing, cleaning or Vor oppositionsgang is optimal.
- the containers are usually made of a water-soluble material. Water-soluble means that the material dissolves in or disperses in water.
- the containers are transparent today, so that the means contained therein are completely visible.
- liquid agents may be provided pre-portioned in respective containers.
- polymeric active ingredients in a stable liquid formulation.
- the problem arises that such polymeric active ingredients are not soluble in the liquid agent or should also not be soluble.
