Use & Application
USP/EP grade spray dried lactose is the preferred filler-binder for direct compression tableting. Its spherical particle shape delivers superior powder flow and high compactability, suitable for high-speed tablet press production. It is widely used in tablets, capsules and sachet formulations, also serves as carrier for dry powder inhalation drugs.
Food grade spray dried lactose acts as flavor carrier, anti-caking agent and texture modifier. It is applied in infant nutrition, confectionery, baked goods and nutritional supplements, improving powder flow and stabilizing aroma components in dry food blends.
Packing
