Description

Lactulose CAS NO 4618-18-2 is a synthetic disaccharide sugar used primarily for its therapeutic and diagnostic properties. It is valued for its ability to act as a prebiotic and an osmotic laxative, promoting gut health and regularity. This high-purity compound is essential for manufacturers in the pharmaceutical, nutraceutical, and food ingredient industries seeking reliable, compliant raw materials.

Application

• Pharmaceutical Active Ingredient: Key component in prescription and OTC medications for the treatment of hepatic encephalopathy and chronic constipation.
• Diagnostic Agent: Used in hydrogen breath tests to diagnose conditions like small intestinal bacterial overgrowth (SIBO) and lactose malabsorption.
• Nutraceutical & Functional Food: Incorporated into dietary supplements, probiotic formulations, and functional foods as a prebiotic to stimulate beneficial gut flora (Bifidobacteria, Lactobacilli).
• Veterinary Medicine: Applied in animal health products for similar therapeutic purposes as in human medicine.
• Research & Development: Serves as a standard or reagent in biochemical and microbiological research studying carbohydrate metabolism and gut microbiology.
• Cosmetic Applications: Occasionally used in skincare formulations for its mild humectant and skin-conditioning properties.
