A built synthetic organic detergent composition, in particulate or patty form, results from extruding such a composition, containing water in sufficient quantity to form at least some hydrate from hydratable builder salt, and with enough free water present to plasticize the composition without resulting in separation of liquid and solid phases, and converting the extrudate to particles or lightly compressing it to pre-measured form-retaining patties or cakes. Also within the invention are processes for making such particulate and patty products, and methods of washing laundry with them. |

DETAILED DESCRIPTION What is claimed is: 1.
A pre-measured form-retaining built synthetic organic detergent composition patty or cake comprised of multiple rod-shaped extrudates of synthetic organic detergent, hydratable builder salt(s) for such detergent, and water, wherein the rod-shaped extrudates are of equivalent diameter in the range of 0.
5 to 3 mm.
and of a length in the range of 0.
5 to 10 cm.
, with the ratio of length to equivalent diameter being in the range of 1:1 to 20:1, with the rods thereof being adhered together sufficiently to be form-retaining while being capable of being easily broken apart by the hands of a consumer, which patty consists of a pre-measured charge of detergent composition for addition to the wash tub of an automatic washing machine.
2.
A patty according to claim 1 which comprises 10 to 30% of synthetic organic detergent, 30 to 70% (anhydrous basis) of hydratable water soluble inorganic builder salt, 10 to 30% (anhydrous basis) of sodium perborate and 20 to 35% of water, with the ratio of weights (anhydrous bases) of such hydratable builder salts to synthetic organic detergent being in the range of 1:5 to 5:1, and with the ratio of weights (anhydrous bases) of such builder salts to water being in the range of 1:1 to 3:1.
3.
A patty according to claim 1 which comprises 10 to 30% of synthetic organic detergent, 30 to 70% (anhydrous basis) of hydratable water soluble inorganic builder salt, 4 to 30% of quaternary ammonium halide and 20 and 35% of water, with the ratio of weights (anhydrous bases) of such hydratable builder salts to synthetic organic detergent being in the range of 1.
5:1 to 5:1, and with the ratio of weights (anhydrous bases) of such builder salts to water being in the range of 1:1 to 3:1.
4.
A patty according to claim 3 wherein the quaternary ammonium halide is in extrudates which contain no synthetic organic anionic detergent.
5.
A detergent composition patty according to claim 1, comprising, by weight, 10 to 30% of synthetic organic anionic detergent, 30 to 70% (anhydrous basis) of hydratable water soluble inorganic builder salt and 20 to 35% of water, with the ratio of weights of such builder salt (anhydrous basis) to synthetic organic anionic detergent being in the range of 1
