Abstract
The invention refers to a solid compact cogranule suitable for use in solid detergent compositions and especially in tablet applications. These cogranules have a granule size from 300 μm to 1400 μm and a bulk density of at least 750 kg/m3, and they comprise alkali metal silicate, carbonate, citrate, and less than 25% water by weight of the cogranule. A method for producing the granule is described.
Claims32
A solid compact cogranule having a granule size from 300 μm to 1400 μm and a bulk density of at least 750 kg/m3;
- wherein the solid compact cogranule comprises an alkali metal silicate, a carbonate and a citrate;
- wherein the solid compact cogranule is granulated from a mixed salt liquid slurry comprising the alkali metal silicate, the carbonate, and the citrate;
- and wherein the solid compact cogranule comprises less than 25% water by weight of the cogranule.
A method for producing a solid compact cogranule comprising an alkali metal silicate, a carbonate, a citrate, and less than 25% water by weight of the cogranule, the method comprising:
- a. dissolving the alkali metal silicate, carbonate, and citrate into water to obtain a mixed salt liquid slurry;
- b. forming compact granules by granulation using the mixed salt liquid slurry of step a;
- and
- c. collecting the formed product of cogranules after sieving.
