blur_circular Chemical Specifications
description Product Description
α-Lactose monohydrate is widely used in the pharmaceutical industry as an excipient in tablet formulations. It acts as a filler or diluent, providing bulk to the tablets and ensuring consistent dosage. Its compressibility and flow properties make it ideal for direct compression processes, simplifying tablet manufacturing. In the food industry, it serves as a sweetener and bulking agent in products like baked goods, confectionery, and infant formula. Its mild sweetness and low hygroscopicity make it suitable for dry mixes and powdered products. Additionally, it is used in microbiology as a nutrient source in culture media for growing bacteria and other microorganisms. Its stability and solubility also make it a preferred ingredient in various industrial applications, including animal feed and fermentation processes.
