Abstract

The present invention discloses liquid compositions that include an active compound, water, and means for inhibiting crystal formation or precipitation of the active compound in the liquid composition.

First claim

What is claimed is:

1. A liquid composition comprising:
an active compound;
water;
a suspending agent; and
means for inhibiting crystal formation or precipitation of the active compound in the liquid composition;
wherein the active compound is lysine.

2. The liquid composition of claim 1 , wherein the active compound is lysine in a free base form.

3. The liquid composition of claim 1 , wherein the means for inhibiting crystal formation or precipitation of the active compound is lecithin.

4. The liquid composition of claim 1 , wherein the active compound is present in the liquid composition at a concentration above a crystallization point of the active compound.

5. The liquid composition of claim 1 , wherein the liquid composition comprises less than 50% fat.

6. The liquid composition of claim 1 , wherein the means for inhibiting crystal formation or precipitation is present at a concentration of 0.1-5% by weight, at a concentration of between 0.5-4% by weight, at a concentration of between 1-3% by weight, or at a concentration of between 1-2% by weight.

7. The liquid composition of claim 4 , wherein the means for inhibiting crystal formation or precipitation is lecithin.

8. The liquid composition of claim 3 , wherein the lecithin is selected from the group consisting of crude filtered lecithin, fluid lecithin, de-oiled lecithin, chemically modified lecithin enzymatically modified lecithin, standardized lecithin, and combinations of any thereof.

9. The liquid composition of claim 1 , wherein the suspending agent is a gum.

10. The liquid composition of claim 1 , wherein the suspending agent is a water soluble polymer.

11. The liquid composition of claim 2 , wherein the lysine is present at an amount of at least 55% by weight, at least 60% by weight, at least 65% by weight, at least 70% by weight, at least 75% by weight, or at least 80% by weight.

12. The liquid composition of claim 1 , wherein the means for inhibiting crystal formation or precipitation further comprises a co-emulsifier having an HLB of between 10-18.

13. A liquid composition comprising:
lysine;
water;
a suspending agent; and
lecithin;
wherein the lysine is present in the liquid composition at a concentration above a crystallization point of the lysine.

14. The liquid composition of claim 13 , wherein the lysine is in a free base form.

15. The liquid composition of claim 13 , wherein the suspending agent is a gum.

16. The liquid composition of claim 13 , wherein the suspending agent is a water soluble polymer.
