Claims
- 1. A cleaning agent composition comprising a solid alkali metal silicate having a molar ratio SiO.sub.2 :M.sub.2 O from about 1.5 to about 3, wherein M is sodium and optionally potassium, wherein the silicate also contains from about 7 to about 20% by weight of sodium carbonate based on the dry material and a water content of from about 14 to about 22% on a total weight basis.
- 2. A cleaning agent composition as claimed in claim 1, further including at least one of a sodium sulfate filler or one or more active cleaning substances selected from the group consisting of surfactants, alkali generating agents other than sodium sulfate or said sodium silicate, bleaching agents or enzymes.
- 3. A cleaning agent composition as claimed in claim 1, comprising from about 1 to about 40% by weight of said alkali metal silicate.
- 4. A cleaning agent composition as claimed in claim 1, wherein said agent is a dishwashing agent composition or a washing agent composition.
- 5. A composition as claimed in claim 1, wherein the alkali metal silicate contains potassium in an amount of from about 1 to about 5% K.sub.2 O based on the dry material.
- 6. A composition as claimed in claim 1, wherein the alkali metal silicate contains potassium in an amount of from about 2 to about 4% K.sub.2 O based on the dry material.
- 7. A composition as claimed in claim 1, wherein the molar ratio SiO.sub.2 :M.sub.2 O is from about 1.8 to about 2.5.
- 8. A composition as claimed in claim 1, wherein the alkali metal silicate is in granular form prepared by compacting a solid powder of alkali metal silicate.
