Formulierung

Working with Alpha Lipoic Acid Powder

The physical properties of Alpha Lipoic Acid matter when the ingredient moves from raw material into a finished dosage form.

Powder Characteristics

This reference batch is a crystalline powder with 100% of the material passing through 40 mesh. The melting point is 60–62°C. These properties are relevant when evaluating powder handling and processing conditions.

Kapseln Particle size and powder handling should be considered alongside the filling process and blend composition.

Tabletten Flow, compaction and processing temperature should be considered during development.

Pulvermischungen Particle distribution and blend uniformity should be checked in the finished system.

Gummies & Chewables Formulation development should account for heat exposure and the behavior of the finished matrix.

Reference Physical Data

The supplied COA provides two useful physical parameters for formulation work.
