Definitions
- the invention relates to the use of formulations for in particular phosphate-free cleaning agents with improved biodegradability for the machine dishwashing.
- Machine dishwashers have the task of cleaning leftovers from dishes, cutlery, glasses, Kitchen appliances etc. to remove.
- the cleaning agent must wet the surfaces to be cleaned convey and disperse and emulsify water-insoluble dirt particles in the washing liquor.
- the cleaner suppresses the foam caused by food residues, the residue is more visible Prevent stains on the wash items as far as possible, remove coffee and tea stains, build up of Films of dirt on the surface of dishes and glassware prevent water hardness Bind substances from water and food waste and destroy bacteria.
- phosphate-free dishwashing detergents have been reduced Developed alkalinity, which often does without the use of chlorine-releasing substances.
- This "Mild" dishwashing detergents are usually based on trisodium citrate combined with polycarboxylates as the most important phosphate substitute.
- the products contain low-foam non-ionic surfactants, Enzymes, oxygen-based bleaches (e.g. sodium perborate) and bleach activators such as.
- B. Tetraacetylethylenediamine Tetraacetylethylenediamine.
- phosphate substitutes did not show sufficient cleanability, other substances, such as B. EDTA, are used little for ecological reasons.
- polycarboxylates in particular homopolymers of acrylic acid and copolymers of acrylic acid, have proven to be and maleic acid, as suitable phosphate substitutes and are used today in commercially available cleaning agents used.
- dishwashing detergents containing polycarboxylates are found in the products as Phospha35 Acrylic polymers used as a substitute have only a low biodegradability and therefore mineralized only to a small extent in the sewage treatment plant.
