FlowLac® 100

FlowLac® 100

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® 100 is the standard grade for spray-dried lactose, which provides an excellent flowability and an extraordinary compactability compared to all other lactose grades.
