Solid composition, comprises at least one particulate solid phase (50-99 wt.%), at least one non-volatile liquid phase (0.1-50 wt.%), and at least one block copolymer (0.01-4 wt.%) obtained from a first monomer of acrylamido-2-methylpropane sulfonic acid or its salt, and a second vinyl monomer having a side chain nitrogen. Independent claims are included for: (1) a method of manufacturing the solid composition comprising mixing the composition to form a paste, developing a mold of the paste, and removing the volatile liquid phase present in the paste； (2) a method for manufacturing a powder composition comprising dispersing the composition in water to obtain the paste, (ii) placing the mixture in the mold, and (iii) removing the water from the paste by suction and drying at below 70[deg] C； and (3) paste comprising 15-80 wt.% of the particulate solid phase, 20-70 wt.% of paste in water, 1-30 wt.% of non-volatile liquid phase, 0.01-2 wt.% of the paste of a polymer gels in water.
