Abstract

The agents are suitable for use at low temperatures and are based on polymeric alkali metal phosphates and/or their substitutes, alkali metal silicates, alkali metal carbonates and, where appropriate, compounds which release active oxygen, and low-foam non-ionic surfactants. They contain enzymes and primary C8-C18-alkylamines which can, where appropriate, be alkoxylated or quaternised.

Following the need to save energy, many manufacturers have Dishwashers have already been brought onto the market as energy-saving models that reduce water consumption the cleaning fleet was not only reduced from 10 to 6 liters, but also an economy program Offer with a greatly reduced temperature. A household dishwasher brought onto the market by the AEG company of the "Favorit de Luxe Electronics i" type, for example, only requires about 6 liters of water. The power consumption of the "40 ° C Normal" program (final rinse temperature: 55 ° C) is, im In contrast to the previously usual consumption of 1.9 to 2.2 kW / h at 65 ° C, only 1.1 kW / h. At work With this machine, however, it has been shown that the cleaning performance of - as previously usual - 30 g Standard cleaner (^ 5 g / l) when transitioning from the 65 ° C program on the 40 C program with 8 test stains fell by an average of 1.4 evaluation points.

While an addition of 1% of an amylase-protease mixture Although the cleaning process improved the removal of oat flakes and starch residues, lipase was added not very effective as a cleaner to increase grease removal. Sebum fat stains left Temperatures around 40 C can only be removed with difficulty.

Surprisingly, it has now been found that the removal of particularly stubborn grease soiling, u / ie z. B. Beef tallow at cleaning temperatures of 40 C above the normal known 65 C result is improved if the dishwashing detergent is not only used with an enzyme mixture as a cleaning booster, but also with primary C -C alkylamines, which may also be alkoxylated or quaternized by methyl halides or dimethyl sulfate, clogs.

One therefore has a number of substances to replace that previously common detergent phosphates proposed. The best have obviously been tried and tested Sodium aluminum silicates in the form of the synthetically produced zeolites of the NaA and NaX types, such as those for example in U.S. Patents 2,882,243 and 2,882,244.

The water-soluble organic complexing agents for calcium are essentially found among the polycarboxylic acids. Hydroxycarboxylic acids, aminocarboxylic acids, carboxy f alkyl ethers, polyanionic polymeric carboxylic acids and phosphonic acids, these compounds mostly in! Form of their water-soluble salts are used. \ Specific but not exhaustive examples are; Citric acid, carboxymethyltartronic acid, mellitic acid,; Polyacrylic acid, poly-cC-hydroxyacrylic acid, carboxymethyl malic acid, nitrilotriacetic acid and 1-kydroxy-ethane-1,1-diphosphonic acid.

Water-soluble sodium or potassium metasilicates are used as alkali metasilicates. You can be anhydrous, be anhydrated or contain water of crystallization and contain 5 to 9 moles of water.

Water glass is understood to mean water-soluble sodium or potassium silicates in which the ratio from alkali oxide to silicon dioxide is about 1: 2 to 1: 4. They can be used as anhydrous solid substances or as liquid, approximately 50% solutions.

The enzymes used are those of animal and vegetable origin, in particular active ingredients obtained from digestive enzymes, yeasts and bacterial strains. They usually provide a complicated composite mixture comparable * VARIOUS enzymatic active ingredients. Of particular interest are starch, protein, or fat splitting enzymes such as Amy read, proteases and lipases. The enzymes are obtained from bacterial strains, fungi, yeast or animal organs using a wide variety of methods and are sold under different names.

The usual data are in LVE / g (Löhlein-Volhard units per gram), IU (international units) and DE / g (DeIfter units per gram) for proteolytic enzymes. Because of the simple analytical method, the activity is often given in LVU / g. In the invention Dishwashing detergents should have a proteolytic enzyme activity of 100 to 5,000, preferably 200 to 2,000 LVU / g. The amylolytic activity is generally given in SKB / g (Sandstedt-Kneen-Blish units per gram). It should be about 5 to 1,000, preferably 15 to 250 SKB / g in the cleaning agent mixture. The amount that is in The enzymes to be used in the dishwashing detergents / are based on these values.
