Definitions

  • the present invention relates to a detergent product comprising a detergent or a washing aid contained in a bag-like structure made of water-soluble material.
  • the materials from which the pouches for the detergents or the detergents or detergent components, hereinafter referred to as "detergents" for short, are made are either insoluble in water or soluble in water. So that the detergents can still be dissolved or dispersed in the water when using water-insoluble materials, the water-insoluble materials must either be water-permeable, or the bags made of water-impermeable, water-insoluble materials must open in the water so that the pouch contents with the water come into contact.
  • the water permeability can be achieved, for example, by perforating or slitting the bag material, or one can use porous materials, for example nonwoven fabrics made from water-insoluble fibers, or fabrics as knitted or woven fabrics.
  • bags made of water-insoluble materials are used, it is necessary to sort the bags out of the washed laundry after the washing process has ended. This is not necessary when using bags made of water-soluble materials. These pouch materials dissolve in contact with the water and are removed with the wash liquor at the end of the washing process. Sorting out the prey materials is thus no longer necessary.
  • Films made from water-soluble polymers have long been known as suitable bag materials for this purpose. Examples of parts of the literature which describe such materials for the production of bags for detergents are Swiss Patent No. 347930 and US Pat. No. 3,277,009. In the Swiss patent mentioned, the storage stability of the detergents packaged in this way is improved by separate packaging in bleaching agents and bleach activators with water-soluble films. US Pat. No. 3,277,009 describes polyvinylpyrrolidone derivatives as materials for the production of water-soluble detergent sachets.
  • water-insoluble also means “not swellable in water” or “not water-dispersible” or “not water-emulsifiable”
  • the bag materials in turn do not contribute to the washing result .
  • the known water-soluble bag materials also have no influence on the washing performance of the detergents contained therein.
  • the object of the present invention was therefore detergent products, comprising to provide a detergent or a washing aid contained in a bag-like structure, the use of which gives an improved washing result.
  • the present invention therefore relates to a detergent product comprising a detergent or auxiliary washing agent which is contained in a sachet-like structure made of water-soluble materials and which is characterized in that the water-soluble material is completely or predominantly a nonionic cellulose ether.
  • Detergent products according to the invention the bags of which are made from the material mentioned, lead to a significantly improved washing result compared to detergent products, the bag material of which consists of another water-soluble material, for example polyvinyl alcohol.
  • Preferred detergent products are those whose bags are made from cellulose ethers that are soluble in cold water. This ensures early release of the detergent and thus optimally long-lasting contact of the detergent with the textiles to be cleaned.
  • laundry detergent products according to the invention whose bag material consists of cellulose ether, which is soluble in cold water, but insoluble in warm water, for example in water at a temperature above 40 ° C.
  • the initially dissolved cellulose ether is precipitated and suspended with increasing water temperature, with the result that the suspended cellulose ether in turn probably serves as a dirt carrier for dirt particles removed from the textiles to be washed.
  • a cellulose ether that has this property is, for example, hydroxypropyl cellulose.
  • Detergent products, the bag material of which is hydroxypropyl cellulose are therefore particularly preferred.
  • Hydroxy-propyl cellulose is understood here to mean hydroxypropyl cellulose in the narrower sense and those cellulose isomers which are predominantly substituted by hydroxypropyl groups. According to the invention, products are used which are at least so high in their degree of substitution that they are soluble in cold water. Products with a high degree of substitution, ie, for example, that they are reacted with about 4 or more moles of propylene oxide per anhydroglucose unit are preferred.
  • Water-soluble films can be produced from hydroxypropyl cellulose as well as water-soluble, water-permeable materials made from fibrous hydroxypropyl cellulose, both for example nonwovens, woven fabrics or knitted fabrics.
  • detergent products are preferred whose bag-like structures are made of a fibrous material.
  • the bag-like structures of which are made from the materials mentioned can be closed after being filled with detergent by sewing, tying, gluing or in particular by welding. Detergent products with bags sealed by welding are therefore preferred.
  • coconut alkyl sulfate Na 12.5% by weight coconut fatty alcohol + 7 moles of ethylene oxide 5.0% by weight soap (based on coconut fatty acid)
  • the bleaching boat was added to the textiles to be washed in pillow-shaped bags made of hydroxypropyl cellulose fiber fleece from Rhodia, which was made from commercially available hydroxypropyl cellulose Klucel ( R ) from Hercules.
  • the bleach booster was additionally used in pillow-shaped bags made of polyvinyl alcohol (prior art). After washing, the washing result was determined by measuring the reflectance of the test textiles in%.
  • the results are in the contain the following Table 1, the first number representing the result for the use of the bleach booster in the polyvinyl alcohol bag and the second number representing the result for the detergent product according to the invention with a bag made of hydroxypropyl cellulose:
  • the detergent product according to the invention delivers the better washing result.
  • the detergent product according to the invention delivered the better washing result on both test textiles.
