Claims
- 1. A phospholipidic composition, whereby said composition is a granulate, said composition containing L-α-glycerophosphatidylcholine in a concentration of at least 10% by weight and at least one granulation aid selected from the group consisting of a monophosphate, diphosphate or triphosphate of an alkali metal, an alkaline earth metal, and a mixture thereof.
- 2. The phospholipidic composition of claim 1, wherein the composition contains the granulation aid in a concentration between 2% by weight and 50% by weight.
- 3. The phospholipidic composition of claim 1, wherein the composition contains the granulation aid in a concentration between 10% by weight and 30% by weight.
- 4. The phospholipidic composition of claim 1, wherein the granules have a particle size between 0.063 mm and 5 mm.
- 5. The phospholipidic composition of claim 1, wherein at least one of cellulose and silicon dioxide is present in the composition.
- 6. The phospholipidic composition of claim 5, wherein the cellulose concentration in the composition is between 0.5% by weight and 30% by weight.
- 7. The phospholipidic composition of claim 6, wherein the cellulose concentration in the composition is between 5% by weight and 20% by weight.
- 8. The phospholipidic composition of claim 5, wherein the cellulose has an average particle size between 60 μm and 150 μm.
- 9. The phospholipidic composition of claim 5, wherein the silicon dioxide concentration in the composition varies between 0.5% by weight and 3% by weight.
- 10. The phospholipidic composition of claim 5, wherein the silicon dioxide has a particle size between 5 nm and 25 nm.
- 11. The phospholipidic composition of claim 5, wherein the silicon dioxide has a surface area between 100 m2/g and 300 m2/g.
- 12. The phospholipidic composition of claim 1, wherein the composition contains at least one calcium salt of phosphoric acid as a granulation aid.
- 13. The phospholipidic composition of claim 12, wherein the calcium salt of phosphoric acid is tricalcium phosphate.
- 14. The phospholipidic composition of claim 13, wherein the tricalcium phosphate contains at least one of less than 10% by weight monocalcium phosphate and less than 10% by weight dicalcium phosphate, each based on the total amount of said tricalcium phosphate.
- 15. The phospholipidic composition of claim 1, wherein the composition is free of binders.
- 16. The phospholipidic composition of claim 1, wherein the concentration of L-α-glycerophosphatidylcholine in the composition is greater than 70% by weight.
- 17. The phospholipidic composition of claim 16, wherein the concentration of L-α-glycerophosphatidylcholine in the composition is between 80% by weight and 95% by weight.
- 18. The phospholipidic composition of claim 1, wherein the composition contains:10 to 80% by weight L-α-glycerophosphatidylcholine; 0 to 40% by weight cellulose; 0.5 to 50% by weight of at least one of calcium monophosphate, calcium diphosphate and calcium triphosphate; and 0.5 to 3% by weight silicon dioxide.
- 19. The phospholipidic composition of claim 18, wherein the composition contains:40 to 70% by weight L-α-glycerophosphatidylcholine; 10 to 30% by weight cellulose; 10 to 30% by weight of at least one of calcium monophosphate, calcium diphosphate and calcium triphosphate; and 1.5 to 2.5% by weight silicon dioxide.
- 20. The phospholipidic composition of claim 1, wherein the L-α-glycerophosphatidylcholine is of vegetable origin.
