Milled and Sieved Lactose

General information

Crystalline alpha-lactose monohydrate grades have a long tradition in pharmaceutical applications due to their chemical and physical stability, in oral, parenteral and inhalative pharmaceutical applications, versatile binder-filler properties, and global availability [1]. Impacting recrystallized alpha-lactose monohydrate particles by either a milling or sieving during production opens multiple opportunities to influence physical characteristics and functional performance.

During the milling process, finer, sharper-edged particles are formed, having cohesive powder properties that can be beneficial during granulation processes. Clean unlubricated surfaces created during the compaction process as a result of brittle fracture lead to improved compactibility [2]. MEGGLE’s milled alpha-lactose monohydrate grades have been historically used as diluents in dry and wet granulation processes by numerous global and regional pharmaceutical manufacturers.

Narrow fractionation of randomly sized lactose crystals results in coarse sieved grades, which show particle size and shapedependent powder flow for increased production speeds. MEGGLE’s sieved alpha-lactose monohydrate grades are mainly monocrystals with some agglomerates, exceptionally suited to permit and optimize applications where powder flow is important.

MEGGLE’s sieved and milled lactose grades are generated by a well-defined manufacturing process resulting in a high degree of crystallinity.
