FlowLac® 90

The product FlowLac is produced by spray-drying a suspension of fine milled alpha-lactose monohydrate crystals in a solution of lactose. When lactose in solution is spray dried, a rapid removal of water is taking place, whereby amorphous, non crystalline lactose is formed in addition to crystalline lactose. Based on the amorphous content, kept on a stable level, non-varying better tabletting properties can be reached. Due to the spray drying process, FlowLac has a spherical agglomerate shape, consisting of small alpha lactose monohydrate crystals bound by amorphous lactose. FlowLac 90 was developed to provide greater compactability compared to FlowLac 100 by optimizing the amorphous lactose content. In addition, the particle size distribution makes FlowLac 90 virtually dust-free.
