DURALAC H
Anhydrous lactose USP/NF, EP, JP

DuraLac H is an anhydrous grade of directly compressible lactose. It is produced by roller-drying a lactose solution at high temperature to form anhydrous beta-lactose and alpha-lactose crystals at levels approximating 80 percent and 20 percent, respectively. During beta-lactose crystallization, no water is incorporated in the crystal lattice resulting only in the non-hygroscopic anhydrous form. Subsequent to roller-drying, anhydrous lactose is milled and sieved to the desired particle size distribution optimizing powder flow and compactibility.
