Description

Lactulose CAS NO 576-08-9 is a synthetic disaccharide sugar used primarily for its therapeutic and nutritional properties. This compound is highly valued for its prebiotic activity and osmotic laxative effects, making it a critical ingredient in pharmaceutical formulations. It is essential for manufacturers in the pharmaceutical, nutraceutical, and functional food industries seeking reliable, high-purity ingredients for digestive health products.

Application

• Pharmaceuticals: Primary active ingredient in prescription and OTC treatments for hepatic encephalopathy and chronic constipation.
• Prebiotic Supplements: Used in dietary supplements and probiotic formulations to selectively promote the growth of beneficial gut bacteria like Bifidobacteria and Lactobacilli.
• Functional Foods & Beverages: Incorporated into dairy products, infant formula, and health drinks to enhance digestive health and nutritional value.
• Veterinary Medicine: Applied in animal health products for treating digestive disorders in livestock and pets.
• Clinical Diagnostics: Utilized in medical test kits, such as the hydrogen breath test, for diagnosing small intestinal bacterial overgrowth (SIBO).
• Research & Development: Serves as a standard or reagent in biochemical and microbiological research studying carbohydrate metabolism and gut microbiota.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
