Mannitol (CAS 87-78-5) is a naturally occurring sugar alcohol with significant industrial and pharmaceutical applications. As a key chemical intermediate and ingredient, understanding its properties, production, and the supply chain dynamics is crucial for B2B buyers. This article provides an in-depth look at Mannitol from a manufacturer's and supplier's perspective.

Chemical Properties and Structure:
Mannitol is a hexitol, chemically represented as C6H14O6. It is an isomer of sorbitol, differing only in the stereochemistry of the hydroxyl group on the second carbon atom. Mannitol appears as a white, crystalline powder or granules, is odorless, and has a sweet taste. Its melting point is around 166-168°C, and it exhibits moderate solubility in water. Its chemical stability and non-reactive nature in many conditions make it a versatile ingredient.

Industrial Production:
While Mannitol occurs naturally in plants like seaweed and mushrooms, industrial-scale production primarily involves the hydrogenation of fructose or glucose. This process yields high-purity Mannitol, essential for pharmaceutical and food-grade applications. Buyers looking to purchase Mannitol should inquire about the manufacturing process and the purity levels achieved. For instance, sourcing Mannitol from China often provides access to large-scale production facilities capable of meeting high volume demands with competitive pricing.

Applications and Market Demand:
The demand for Mannitol is driven by its diverse applications. In pharmaceuticals, it's used as an osmotic diuretic to manage conditions like elevated intracranial and intraocular pressure. In the food industry, it serves as a low-calorie sweetener, bulking agent, and humectant in products like sugar-free candies and baked goods. Its utility extends to cosmetics and research laboratories.

Sourcing and Supply Chain Considerations:
When seeking to buy Mannitol, B2B professionals should focus on establishing relationships with reliable manufacturers and suppliers. Key factors include:

* Purity and Quality: Ensure the Mannitol meets specific industry standards (e.g., USP, EP, FCC). Purity levels of 98% and above are common for pharmaceutical and food applications.

* Supply Stability: A consistent and reliable supply is vital for manufacturing operations. Look for suppliers with established production capacities and robust logistics.

* Pricing: Bulk purchases often lead to better pricing. Compare quotes from different suppliers to secure the most cost-effective option.

* Certifications: Verify relevant certifications such as ISO, GMP, or Kosher/Halal if required for your specific application.

By understanding these aspects, procurement managers can confidently source Mannitol, a vital component for many industries, and build a resilient supply chain.
