DuraLac H
€0.00
Description
DuraLac® H is produced by roller-drying a lactose solution at high temperature to form anhydrous beta-lactose and alpha-lactose crystals at levels approximating 80% and 20%, respectively. During beta-lactose crystallization, no water is incorporated in the crystal lattice resulting in lactose´s anhydrous form.
Subsequent to roller-drying, anhydrous lactose is milled and sieved to the desired particle size distribution, optimizing powder flow and compactability. DuraLac® H deforms by brittle fracture during compaction, it is well-suited for directly compressed and dry granulated formulations (roller compaction, slugging).
