Description

B,B-Trehalose CAS NO 499-23-0 is a non-reducing disaccharide sugar composed of two glucose molecules linked by an alpha,α-1,1-glycosidic bond. This unique molecular structure provides exceptional stability, making it a highly effective protectant for biomolecules and cells against various environmental stresses. It is a critical ingredient for industries requiring reliable stabilization and preservation. Key sectors that utilize this compound include pharmaceuticals, cosmetics, food technology, and biotechnology.

Application

• Pharmaceutical Excipient & Stabilizer: Used as a cryoprotectant and lyoprotectant in the formulation of vaccines, antibodies, enzymes, and other biopharmaceuticals to maintain stability during freeze-drying and storage.
• Cosmetic & Personal Care Ingredient: Functions as a natural moisturizing factor (NMF) and humectant in skincare products, helping to hydrate and protect the skin barrier.
• Food & Beverage Additive: Employed as a sweetener, texturizer, and shelf-life extender in processed foods, confectionery, and health supplements due to its mild sweetness and stability.
• Biotechnology Reagent: Serves as a stabilizing agent for enzymes, antibodies, and other labile proteins in diagnostic kits and research applications.
• Cell Culture & Preservation: Acts as a protective agent for mammalian cells, bacteria, and yeast during freezing and long-term cryogenic storage.
• Agriculture & Animal Feed: Investigated for use in enhancing stress tolerance in plants and as a feed additive for gut health and performance.

Quality Control

Our B,B-Trehalose is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for food, pharmaceutical, and research applications. Specifications are aligned with industry benchmarks, including Food Chemicals Codex (FCC) and USP-NF where applicable. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and safety parameters is provided with every shipment.

Storage

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