Attorney, Agent or Firm:
A process for the production of tablet form detergent compositions is afforded, comprising: (a) the partial hydration of from 10 to 60 parts by weight of an anhydrous sodium polyphosphate to form from 30 mole percent to less than 80 mole percent of tripolyphosphate hexahydrate; (b) mixing the partial hydrate with from 20 to 70 parts by weight of a powder-form, substantially anhydrous sodium silicate (Na.sub.2 O: SiO.sub.2 =1:1 to 1:4); (c) spraying the mixture with water or an aqueous silicate solution; and (d) granulation by agitation, followed by crystallization, other detergent ingredients optionally being added along with bleaches or enzymes, and adding from 1 to 5% by weight of sodium acetate or from 0.5 to 3% by weight of dicalcium phosphate dihydrate or a mixture thereof as a tableting aid, followed by tableting under a pressure of more than 70 kp/cm.sup.2, leading to mechanically strong, but rapidly dissolving tablet form detergent compositions. |

DETAILED DESCRIPTION We claim: 1.
In a process for manufacturing detergent compositions in tablet form by mixing the ingredients and then tableting the mixture, the improvement comprising the sequential steps of: hydrating partially from about 10 to 60 parts by weight of an anhydrous sodium tripolyphosphate with a sufficient quantity of water to form from about 30 mole percent to less than about 80 mole percent of tripolyphosphate hexahydrate; mixing said partial hydrate after a residence time of from about 5 to 60 seconds with from about 20 to 70 parts by weight of a powder form, substantially anhydrous, sodium silicate consisting essentially of Na.
sub.
2 O and SiO.
sub.
2 in a ratio of from 1:1-4, followed by spraying with water or with an aqueous sodium silicate solution; and granulating the product by agitation, followed by crystallization; adding tableting aids and any remaining ingredients desired to the granulate and further mixing; said tableting aids consisting essentially of sodium acetate in a quantity of about 1 to 5% by weight, dicalcium phosphate dihydrate in a quantity of 0.
5 to 3% by weight, or a mixture thereof, all based upon the weight of the entire composition to be tableted; and tableting the composition under pressures of more than 70 Kg/cm.
sup.
2.
2.
The process of claim 1, wherein said granulate is completely crystallized and has a powder density of from about 800 to 1200 g/l.
3.
The process of claim 2, wherein said granulate has a powder density of from about 850 to 1100 g/l.
4.
The process of claim 2, wherein said granulate has a powder density of from about 850 to 1100 g/l.
5.
The process of claim 1 wherein said remaining ingredients desired are mixed with said granulate along with bleaches or enzymes, the tableting aids are added and mixed to constitute the final composition, and said final composition is tableted.
6.
The process of claim 1 wherein said sodium acetate, is present it is in a quantity of about 2 to 3% by weight and when said dicalcium phosphate dihydrate is present it is in a quantity of about 0
