Description

Mannitol CAS NO 87-78-5 is a naturally occurring sugar alcohol (polyol) widely recognized for its excellent stability, low hygroscopicity, and pleasant, cooling taste. It serves as a critical multifunctional excipient and sweetening agent in pharmaceutical formulations and food products. This versatile compound is essential for manufacturers in the pharmaceutical, food and beverage, and chemical synthesis industries seeking reliable, high-purity ingredients.

Application

• Pharmaceutical Excipient: Primarily used as a non-hygroscopic diluent in tablet formulations, a bulking agent in freeze-dried injectables, and as an osmotic diuretic in medical solutions.
• Food & Beverage Industry: Functions as a low-calorie sweetener, anti-caking agent, texturizer, and stabilizer in sugar-free confectionery, chewing gum, and baked goods.
• Chemical & Industrial Synthesis: Acts as a starting material or intermediate in the production of resins, surfactants, and plasticizers.
• Diagnostic Reagents: Used in culture media and various biochemical test kits as a substrate or stabilizing agent.
• Personal Care: Incorporated into toothpaste and mouthwash formulations for its sweetening and bodying properties.

Quality Control

Our Mannitol is manufactured under strict quality management systems. We offer grades compliant with major pharmacopeial standards, including USP-NF, EP, BP, and JP, as well as FCC for food applications. Every batch undergoes rigorous analytical testing to ensure identity, purity, and safety. A comprehensive Certificate of Analysis (COA) is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Although mannitol has low hygroscopicity, prolonged exposure to high humidity should be avoided to prevent caking.
