- SUBSTITUTESHEET B at least one amphoteric surfactant which functions effectively in hard water, will not cause calcium car ⁇ bonate to precipitate during the washing process, has a low foaming profile and is selected from the group tallow ampho-polycarboxy glycinate, N-(2-carboxy ethyl) -N-octyl- ⁇ -alanine, mixed C8-amphocarboxylates and caprylo-amphocarboxy propionate;
- a sequestering agent selected from phosphates, polyacrylates and carboxylates, said detergent having been buffered to provide a pH-value of 8.0-11.0, prefer- ably 8.5-10.5, for a 0.3% ready-for-use solution of the detergent in water.
- the invention also relates to a method for producing the inventive powdered detergent, said method being charac- terized by

- Citrate is normally present in a concentration within the range of 10-30, preferably 15-20 percent by weight, while the tartrate concentration is within the range of 2-15, preferably 2-5 percent by weight.
- citrate and tartrate mixtures are used, the lower part of respective preferred concentration ranges are applied in order to avoid an excessively high combined concen ⁇ tration.
- the gluconate When gluconate, and then particularly sodium gluconate, is used alone, the gluconate is normally present in the inventive detergent in a concentration within the range of 5-25, preferably 5-10 percent by weight, although this percentage may advantageously be beneath 5 percent by weight when the gluconate is pres ⁇ ent in combination with another sequestering agent, such as a citrate and/or a tartrate.
- another sequestering agent such as a citrate and/or a tartrate.
- the component F) included in the inventive detergent may consist of phosphates, preferably sodium tripolyphos- phate, and which are then present in the inventive detergent in a concentration which is normally within the range of 10-35, preferably 15-20 percent by weight.
- carboxylates as component F) in the inventive detergent are polyacrylates which are then present in a concentration which is normally within the inventive detergent

- this further seques ⁇ tering agent normally being used in a concentration within the range of 0.05-0.5, preferably 0.08-0.15 percent by weight.
- the agent When using an antioxidation agent, the agent is mixed in stage II) dissolved in the component C) . Also mixed in stage II) is the aforesaid sequestering agent which is not included in component F), or a minor part of the carboxylates used as component F) , said sequestering agent being dissolved in the component B).
- the inventive method is particularly advantageous when percarbonate is used as component E) in the inventive detergent.
- Percarbonates such as sodium percarbonate.
- SUBSTITUTESHEET have a relatively unstable structure, which causes problems with regard to the durability of the product when used as a dishwashing detergent.
- the degradation of the percarbonate is namely accelerated in the presence of other substances, such as heavy metals, readily oxidizable substances and moisture.
- the inventive method is based on the known so-called agglomeration technique for the manufacture of launder- ing and dishwashing detergent powders.
- agglomeration technique solid powder particles are mixed with liquid substances in droplet form.
- the agglomeration technique enables powder detergents for dishwashing machines to be manufactured at high litre weights and high concentrations of active substances.
- the detergent components are mixed in stages, so that those sub- stances which have an destabilizing effect on percar- bonates are first encapsulated so as to obtain a surface coating which counteracts degradation, and it is only thereafter that the requisite amount of percarbonate is added to the system.
- SUBSTITUTESHEET According to one modification of the inventive method in which disilicate and/or sodium carbonate are included in component A) and sodium percarbonate is used as or included in component B), the major part of the disili- cate and/or the sodium carbonate is mixed in stage I) and the remainder is mixed together with the component E) in stage III).
- a number of powder detergents for dishwashing machines were produced in an agglomerator of the type Forberg Mixer from Halvor Forberg A/S, Larvik, Norway.
- stage I the solid components A), D) and F) intended for this stage were mixed in the aforesaid agglomerator, said components being finely divided in air.
- Liquid surfactants the components B) and C) with substances optionally dis ⁇ solved therein were then sprayed onto the fluidized or airborne mixture of solid particles in the form of fine droplets in a second stage (stage II in the Table), the amphoteric surfactant being preferably sprayed first and then the nonionic surfactant.
- the bleaching agent (component E) ) and, when applicable, a part of the substances included in component A) of the inventive detergent were then mixed with the previously mixed components in a third stage (stage III in the Table).
- Example 7 represents the best mode contemplated at present for carrying out the invention.
- Lipolase lipase from Novo Nordisk A/S, Denmark
- N-(2-carb ⁇ xyethy1)-N- octyl- ⁇ -alanine (Ampholak YJH 40 Berol Nobel,Sweden) 3.5 4.5 3.0 1 - 2.15
