Storage stable choline chloride compositions
The present disclosure encompasses a composition comprising three-dimensional shapes, wherein each shape consists essentially of choline chloride, and methods of making such three-dimensional shapes.
1. A composition comprising three-dimensional shapes, wherein each shape consists essentially of choline chloride, and no dimension of each shape may measure more than 50 mm or less than 5 mm, and wherein the choline chloride has a concentration of at least about 90 wt %.
2. The composition of claim 1 , wherein the three-dimensional shape is selected from the group consisting of spheres, cones, disks, shields, rectangles, sticks, cubes, triangles, ovals, bullets, shells, barrels, eggs, pucks, bricks, arrowheads, compound cups, arc triangles, pillows, diamonds, half-moons, and almonds.
3. The composition of claim 1 , wherein each shape has a uniform density.
4. The composition of claim 1 , wherein the density of each shape is no more than about 2.0 g/cm 3 .
5. The composition of claim 1 , wherein the volume of each shape is no more than about 10 cm 3 .
6. The composition of claim 1 , wherein the hardness of each shape as measured immediately after production is at least about 40 N.
7. The composition of claim 1 , wherein the hardness of each shape as measured after about 6 months of storage is at least about 40 N.
8. The composition of claim 1 , wherein no more than 20% fines (product not compacted into three-dimensional form) remain from the compaction process.
9. The composition of claim 1 , wherein the visual dissolution time of each shape is no more than about 10 minutes using USP Apparatus II (paddles), at 100 rpm, in 900 mL of water at 37° C.
10. The composition of claim 1 , wherein the composition comprises no more than 0.5% water immediately after production, as determined by Method I <921> USP 38.
11. The composition of claim 1 , wherein the composition comprises no more than 0.5% water after one year of storage in moisture resistant packaging, as determined by Method I <921> USP 38.
12. The composition of claim 1 , wherein the composition does not substantially cake after storage of at least one year in moisture resistant packaging.
13. A composition comprising three-dimensional shapes, wherein each shape consists essentially of choline chloride, wherein the composition is obtained by a process comprising the steps of (a) providing material consisting essentially of choline chloride and (b) compacting the material to produce a solid three-dimensional shape wherein no dimension of the shape may measure more than 50 mm or less than 5 mm, wherein the choline chloride has a concentration of at least about 90 wt %.
14. The composition of claim 13 , wherein the composition does not substantially cake after storage of at least one year in moisture resistant packaging.
15. The composition of claim 13 , wherein the three-dimensional shape is selected from the group consisting of spheres, cones, disks, shields, rectangles, sticks, cubes, triangles, ovals, bullets, shells, barrels, eggs, pucks, bricks, arrowheads, compound cups, arc triangles, pillows, diamonds, half-moons, and almonds.
16. The composition of claim 13 , wherein the density of each shape is uniform.
17. The composition of claim 13 , wherein the density of each shape is no more than about 2.0 g/cm 3 .
18. The composition of claim 13 , wherein the volume of each shape is no more than about 10 cm 3 .
19. The composition of claim 13 , wherein the hardness of each shape as measured immediately after production is at least about 40 N.
