Magnesium carbonate for direct compression

MAGNI-PRESS™ 90 is a magnesium carbonate offering an excellent aptitude for direct compression and very good flowing properties.

MAGNI-PRESS™ 90 is the perfect ingredient for the formulation of dietary supplements in the form of tablets or capsules. It can be used as a source of magnesium, a compression excipient and a filler.


MAGNI-PRESS™ 90 is a magnesium carbonate, co-granulated with pregelatinized corn starch. It is a granulated powder extremely consistent in particle size and range from batch to batch.

MAGNI-PRESS™ 90 has unique properties making it particularly attractive in the formulation of tablets and capsules:

  • Source of magnesium:

MAGNI-PRESS™ 90 contains 90% magnesium carbonate, which equals to 22.50g of Mg per 100g of MAGNI-PRESS™ 90.

  • Excellent compressibility and rapid disintegration:

MAGNI-PRESS™ 90 can be used in the manufacture of tablets by direct compression, providing excellent hardness to tablets without impacting disintegration or dissolution times.

  • High density and good flow:

MAGNI-PRESS™ 90 is suitable for high dose and high speed tableting, ensuring a fluid process.

  • Less abrasive particles:

Use of MAGNI-PRESS™ 90 helps reduce wear on compression equipment and extend tableting tool life.

  • Optimized production costs:

MAGNI-PRESS™ 90 helps reduce processing costs and time by avoiding an additional granulation step.
