How to Determine Food Grade Capsule Density of Dimagnesium Malate Powder

What is Dimagnesium Malate Powder?

Dimagnesium malate powder is a compound made from magnesium and malic acid. used as a novel food ingredient and as a source of magnesium in foods for the general population, food supplements, total diet replacement for weight control and food for special medical purposes.

How To Determine Capsule Density?

The density of food-grade dimagnesium malate powder, used in capsules, is not a standard, readily available measurement. Dimagnesium malate is a white, free-flowing powder with a hygroscopic nature, meaning it absorbs moisture from the air. Its molecular weight is 171.44 g/mol. The specific density of the powder in a capsule will depend on factors like the capsule size, the amount of powder per capsule, and the degree of compaction during encapsulation.

1. Bulk Density Test

Capsule density helps calculate how much powder fits in a capsule (e.g., size 00, 0, etc.).

  • Gently pour powder into a graduated cylinder without tapping.
  • Record the volume (in mL) and weigh the powder (in g).
  • Bulk Density = Weight / Volume (g/mL)

2. Tapped Density Test

  • Tap the cylinder 100–500 times until volume stabilizes.
  • Record new volume.
  • Tapped Density = Weight / Tapped Volume

3. Carr’s Index and Flowability (optional)

  • Carr’s Index = [(Tapped – Bulk) / Tapped] × 100
  • Below 15% is good flow, above 25% may require excipients.

4. Capsule Fill Estimation

Using density and capsule size charts (available online), you can estimate how much dimagnesium malate powder will fit in a capsule. For example:

Capsule Size Max Volume (mL) Approximate Fill (g at 0.65 g/mL)
0 0.95 mL ~0.62 g
0 0.68 mL ~0.44 g

Adjust depending on your actual measured density.

If the powder is fluffy, low-density, or sticky:

  • Consider blending with excipients like microcrystalline cellulose (MCC), silica, or magnesium stearate to improve flow and compression.
