Applications:
Lactose is widely used as a filler or diluent for tablets and capsules, and sometimes in freeze-dried products and baby food formulas. Lactose is also used as a diluent in powder inhalers.

Other applications include: as a carrier/diluent in inhalants and lyophilized formulations. Lactose is added to the lyophilization solution to increase bulk and aid in the formation of lyophilized lumps. Lactose is also mixed with sucrose in a ratio of approximately 1:3 and used as a coating solution.

Generally speaking, which grade of lactose to choose depends on the pharmaceutical dosage form being developed. Lactose for direct compression is often used for tablets with a small drug content, which can save the granulation process.

Packaging:
25 kilograms per kraft paper bag or according to the specific requirements from customers.

Storage Conditions:
Preserved in unopened original containers in a cool dry place before using; kept away from direct sunlight, heat and moisture.

Shelf Life:
24 months if stored under above conditions.

Air and Water Reactions:

Water soluble.

Reactive Group:

Alcohols and Polyols

Reactivity Profile:

Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
