- Application Information
- Due to their neutral taste and ease of use, they are a preferred source for magnesium in food, beverages, nutritional supplements and pharmaceuticals.
- Agglomerated forms of trimagnesium citrate allow the direct compression of tablets.
- Being an excellent desiccant, it is commonly used to stabilise dry blends and to protect water sensitive ingredients.

Technical Details & Test Data
- Particle Size Distribution
Particle size distribution
Particle size distribution is a very important parameter for the tableting process. Lower fine content causes less issues and cleaning effort during production which improves process times and output. Figure 1 shows the particle size distribution analysis of two tested trimagnesium citrate anhydrous granulations.
Trimagnesium citrate anhydrous GN (TMC GN) is a granulated product and has significantly lower fines and a broader particle size distribution compared to the non-granulated trimagnesium citrate anhydrous fine (TMC fine).
As a granulated salt, trimagnesium citrate anhydrous GN shows enhanced flowability, which improves its overall processability compared to the non-granulated product.
Hardness
Figure 2 shows the tensile strength of tablets with different percentages of trimagnesium citrate anhydrous GN. The tensile strength decreases as the content of trimagnesium citrate anhydrous in the tablets increases. The data shows that to achieve a tensile strength of 1.0 MPa the proportion of trimagnesium citrate anhydrous GN in the formulation must not exceed 70%. However, it is still possible to achieve almost 600 kPa with 90% trimagnesium citrate anhydrous GN using a compression force of 60 kN (236 MPa).
Comparing the tensile strength of tablets containing trimagnesium citrate anhydrous GN with tablets containing trimagnesium citrate anhydrous fine at 45 kN and 60 kN press force shows that there is a slight difference. The tablets with trimagnesium citrate anhydrous fine are slightly harder with the same press force (figure 3).
