Description

Diglycerol is a versatile polyol compound, also known as bis(2,3-dihydroxypropyl) ether, formed by the condensation of two glycerol molecules. This high-purity chemical serves as a valuable building block and functional intermediate, prized for its dual hydroxyl functionality and hydrophilic character. It is essential for manufacturers in the personal care, pharmaceutical, and specialty chemical industries seeking to create humectants, emulsifiers, and reactive modifiers. Our supply of Diglycerol CAS NO 59113-36-9 ensures consistent quality and reliable availability for your formulation needs.

Application

• As a humectant and moisturizing agent in advanced skincare, haircare, and cosmetic formulations.
• As a key building block for synthesizing specialty polymers, including polyesters and alkyd resins.
• As a plasticizer and viscosity modifier in industrial coatings, adhesives, and sealants.
• In the production of non-ionic surfactants and emulsifiers for agrochemicals and cleaning products.
• As a pharmaceutical excipient and solvent in drug delivery systems.
• As a cross-linking agent and reactive diluent in epoxy and polyurethane systems.
• In food-grade applications as a stabilizer and texturizer (subject to appropriate purity grades and certifications).
• For research and development in green chemistry as a bio-based platform chemical.

Quality Control

Our Diglycerol is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting key parameters such as assay, water content, and impurity profile is provided with each shipment. We support compliance with relevant industry standards, and specifications can be tailored to meet pharmaceutical (GMP), cosmetic, or food-grade requirements upon request.

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). This product is hygroscopic (moisture-sensitive). To prevent moisture absorption and maintain product integrity, ensure containers are sealed immediately after use.
