Description

Diglycerol is a versatile polyol compound, a dimer of glycerol, valued for its excellent humectant, solvent, and chemical intermediate properties. Its bifunctional nature, featuring multiple hydroxyl groups, makes it a crucial building block for synthesizing polymers, surfactants, and specialty esters. This product is essential for manufacturers in the cosmetics, personal care, pharmaceutical, and polymer industries seeking a high-purity, multifunctional ingredient.

Application

• Cosmetics & Personal Care: Used as a humectant and moisturizer in creams, lotions, and hair care products for superior skin feel and hydration.
• Polymer & Resin Production: Serves as a monomer or cross-linking agent in the synthesis of alkyd resins, polyurethanes, and unsaturated polyesters.
• Pharmaceuticals: Employed as an excipient, solvent, or intermediate in drug formulations and controlled-release systems.
• Surfactants & Esters: A key raw material for producing non-ionic surfactants, emulsifiers, and plasticizers through esterification reactions.
• Food Industry (as an additive): Functions as a humectant, solvent, or texturizer in certain food applications where permitted.
• Lubricants & Functional Fluids: Used as a base or component in synthetic lubricants and heat transfer fluids.
• Chemical Synthesis: Acts as a versatile intermediate for further chemical modifications to create specialty chemicals.

Quality Control

Our Diglycerol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for demanding industrial and specialty applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent absorption of atmospheric moisture. Keep away from strong oxidizing agents.
