Definitions

  • a further object of the invention was to obtain a phosphate- and chlorine-free detergent for dishwashers, which also meets all the requirements of water protection and has the necessary washing activity to completely remove all dirt on dishes and cutlery without attacking the wash ware .
  • the phosphate and chlorine-free detergents and dishwashing detergents according to the invention are defined in claim 1.
  • a preferred composition for such a textile detergent contains, in addition to the detergent substances and citric acid, a detergent-enhancing component (activator), alkali carbonates for setting the desired pH, alkali silicates, sequestering agents, optical brighteners, enzymes and optionally dyes and perfume.
  • a combination of amphoteric and non-ionic and / or anionic surface-active substances are preferably suitable as detergent substances for textile detergents.
  • preparations based on sodium lauryl sulfates such as the commercial product "Texapon” (Henkel AG) or natural soaps such as basic soap, or mixtures thereof, can be used as anionic surface-active substances.
  • Known products based on ethoxylene can be used as the non-ionic surface-active substance higher fatty alcohols, such as the "Lutensole” from BASF and others, and fatty alcohols are used.
  • Suitable amphoteric surface-active substances are, for example, the products sold under the "Ampholak” brand by Berol Nobel AB.
  • the detergent-active substances are advantageously present in a total amount of 10-50% by weight in the textile detergent according to the invention. Thanks to this combination of active washing substances, the washing power of the product is independent of the washing temperature; all the more so since there is no bleaching agent component which exerts its action only at elevated temperatures, for example above 60 ° C.
  • NTA can be added, especially in the form of its trinate salt as e.g. is available from BASF as "Trilon". In an amount of up to 10% by weight, it replaces the phosphates previously used and also acts as an antioxidant.
  • Citric acid or its salts should also be mentioned as a key component. In an amount of 1-20% by weight it ensures the good solubility of the detergent and at the same time acts as a sequestering agent.
  • the activator component preferably contains borates and / or perborates (commercially available sodium borate and / or perborate), and usually in an amount of 10-20% by weight.
  • Optical brighteners can also be used to support the activator component, usually in an amount of up to 1% by weight can be added.
  • the products available under the "Tinopal” brand from CIBA-GEIGY AG have proven themselves very well for this purpose.
  • proteases in particular a mixture of Savinase and Esperase, or also Alcalase, as well as lipases and aminolytic enzymes such as "Termamyl" have proven to be outstanding.
  • the named enzymes which are generally used in a total amount of 0.5-8% by weight, are available from Novo Nordisk Industrie, Copenhagen.
  • This agent which keeps the loosened dirt particles in suspension and, if the detergent is in the form of tablets, also contributes to their rapid disintegration in water, can be added in an amount of usually up to 8% by weight.
  • Zeolites generally in an amount of 5-40 wt% to increase the complexing effect for alkaline earth and Metal ions in the water. Suitable products are commercially available from Degussa.
  • Sodium carbonate and / or bicarbonate can be added in a total amount of 3-20% by weight in order to set the desired pH of about 10-12, preferably 10-11.
  • Fiber and corrosion protection agents As such, sodium metasilicate and disilicate are preferably used in an amount of 5-15% by weight.
  • the most important advantage of the detergents according to the invention is the complete absence of phosphates and chlorine and of fillers.
  • Textile washing agents are produced in a simple manner from the above-mentioned components.
  • the ingredients are mixed very well without the addition of solvents. of any kind.
  • a mixture A which contains the amphoteric and, if present, the anionic surface-active substances together with stabilizing and washing activity-enhancing agents, such as sodium carbonate and / or sodium bicarbonate, sodium silicate, carboxymethyl cellulose and zeolite.
  • stabilizing and washing activity-enhancing agents such as sodium carbonate and / or sodium bicarbonate, sodium silicate, carboxymethyl cellulose and zeolite.
  • mixture B is prepared from the nonionic surface-active substances using stabilizing agents which increase washing activity, such as sodium carbonate-sodium bicarbonate, carboxymethyl cellulose and zeolite.
  • the two mixtures A and B are then combined and combined with the remaining constituents, namely borate and / or perborate, enzymes, citric acid, optical brighteners and, if appropriate, perfume and dyes.
  • the free-flowing product obtained in this way generally tends to form lumps. It is therefore advisable to process it into tablets which are used in a preferred dosage of 12 g / kg dry laundry for machine and hand washing.
  • the powder mixture can be compressed into tablets without any further additives.
  • This form has several advantages over free-flowing powder mixtures. Their dosage is much simpler, the packaging, for example in the blister packs popular today, is impermeable to air and moisture, space-saving and environmentally friendly and enables the detergent to be used without being touched by the consumer.
  • the components are chosen such that the tablets easily disintegrate in contact with water and immediately dissolve completely in the wash liquor, even at low temperatures.
  • the tablets preferably have a weight of 12 g and a diameter of 30-32 mm, and are advantageously added directly to the laundry in the washing drum.
  • the agents according to the invention not only meet all official requirements with regard to environmental and water protection, they do not contain any harmful substances and have proven to be completely harmless to human and animal health, insofar as the usual ones Precautions and dosages are observed as they generally apply to household chores.
  • the detergents are harmless to all types of fabrics and fibers, protect even the most delicate textiles, do not attack textile colors and result in surprising removal of dirt and stains even in cold water, but much more at temperatures of 40-60 ° C . Comparative experiments with washing processes at 60 ° C and 95 ° C have shown that the laundry was not cleaned better or faster during cooking. Investigations are ongoing into the disinfectant effect of the detergents according to the invention.
  • a recommended composition of detergents is as follows (in percent by weight):
  • wash-active substances (amphoteric) 5-15, preferably 8-12
  • the invention further comprises a new detergent for dishwashers, which is based on the same principles, is completely free of phosphate and chlorine and has an excellent cleaning power with the utmost care for dishes (also with delicate decor), cutlery and glasses and a brilliant shine.
  • a suitable composition comprises, in% by weight:
  • This agent too, can advantageously be pressed without further addition to handy and easily dissolvable tablets of preferably 8 g.
  • One tablet is placed in the powder compartment of the dishwasher.
  • Amphoteric surfactants 10 ("Ampholak")
  • Noniogenic surfactants (“Dobanol”) 6.4
  • Components A and B were individually mixed well and then combined with the remaining components of component C.
  • the free-flowing powder obtained is compressed in the usual way to tablets of 12 g, with a diameter of 30-32 mm.
  • the dosage depends on the hardness of the water, but is generally 1 tablet à 12g / kg dry wash.
  • Amphoteric surfactants (“Ampholak”) 5 kg
  • Non-ionic surface-active agent (“Lutenol”) 3 kg
  • the tablets obtained were packed airtight; when used, they are placed directly in the powder compartment of the machine.
  • the dosage is based on the information provided by the machine manufacturer. Usually 1 tablet is sufficient for a normal wash.
  • the use of an additional Rinse aid can be recommended if the water hardness is high, but is not necessary in most cases.

Abstract

Les nouveaux produits sans danger pour l'environnement, à base de substances tensioactives non-iogènes et/ou anioniques à activité détergente contiennent en outre, des agents tensioactifs amphotères et de l'acide citrique ou ses sels, ainsi que d'autres substances auxiliaires. Grâce à leur haute activité détergente, la consommation de tels produits est très faible tant pour le nettoyage des textiles que pour celui de la vaisselle.
