Safety Information
Use
There are two anhydrous forms of lactose: a-lactose and b-lactose. The temperature of crystallization influences the ratio of a- and blactose. The anhydrous forms that are commercially available may exhibit hygroscopicity at high relative humidities. Anhydrous lactose is produced by roller drying a solution of lactose above 93.5°C. The resulting product is then milled and sieved. Two anhydrous a-lactoses can be prepared using special drying techniques: one is unstable and hygroscopic; the other exhibits good compaction properties. However, these materials are not commercially available.
