Claims12
A method for producing material-protective dishwashing detergent formulations for automatic machine dishwashing which comprises adding a reduced-phosphate builder system comprised of
- a) 25 to 54.9% by weight of alkali metal tripolyphosphate, and
- b) 0.1 to 30% by weight of iminodisuccinic acid and/or its alkali metal salts to said formulations.
Dishwashing detergent formulations for machine dishwashing, comprising, as a builder system
- a) 25 to 54.9% by weight of alkali metal tripolyphosphate, and
- b) 0.1 to 30% by weight of iminodisuccinic acid and/or its alkali metal salts, and also
- c) 1 to 15% by weight of low-foaming nonionic surfactants and
- d) 0.1 to 30% by weight of bleach and optionally bleach activators.
Machine dishwashing process for dishware, wherein said dishware is washer in a washing machine with a dishwashing detergent formulation is used therein which comprises, as a builder system,
- a) 25 to 54.9% by weight of alkali metal tripolyphosphate, and
- b) 0.1 to 30% by weight of iminodisuccinic acid and/or its alkali metal salts, sodium salts, and also
- c) 1 to 15% by weight of low-foaming nonionic surfactants and
- d) 0.1 to 30% by weight of bleach and optionally bleach activators.
