Description

Tetraglycerol is a versatile polyglycerol compound, a key intermediate and functional ingredient in advanced chemical synthesis. Its value lies in its multi-hydroxyl structure, which provides excellent hydrophilicity, reactivity, and compatibility for creating tailored performance materials. This product is essential for manufacturers in the cosmetics, pharmaceuticals, and specialty chemical industries seeking to develop high-performance emulsifiers, solubilizers, and polymer precursors.

Application

• Primary raw material for synthesizing polyglycerol esters, widely used as non-ionic emulsifiers in food, cosmetics, and pharmaceuticals.
• Key intermediate in the production of dendrimers and hyperbranched polymers for drug delivery systems and nanotechnology applications.
• Building block for specialty surfactants and lubricants requiring high thermal stability and biodegradability.
• Humectant and moisturizing agent in high-end cosmetic and personal care formulations such as creams, lotions, and serums.
• Cross-linking agent and modifier in the synthesis of alkyd resins, polyurethanes, and epoxy systems to enhance flexibility and adhesion.
• Solubilizer and carrier for active pharmaceutical ingredients (APIs) in drug formulation to improve bioavailability.

Quality Control

Our Tetraglycerol is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, hydroxyl value, and water content are available upon request. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect product quality.
