Description

Diacetin is a versatile chemical compound, also known as glyceryl diacetate, valued for its excellent solvent properties and role as a plasticizer and intermediate. Its ability to act as a humectant and solvent makes it a critical component in formulations requiring controlled moisture and solubility. This product is essential for manufacturers in the coatings, plastics, food, and pharmaceutical industries seeking reliable performance additives.

Application

• As a plasticizer and softening agent in cellulose-based plastics and coatings.
• Used as a solvent for dyes, inks, and resins in industrial manufacturing processes.
• Functions as a humectant and softening agent in tobacco products and adhesives.
• Employed as a food additive (E1517) for its solvent and humectant properties in flavorings and food processing.
• Serves as a chemical intermediate in the synthesis of more complex glyceryl esters and other derivatives.
• Acts as a coalescing agent and film former in latex paints and coating formulations.

Quality Control

Our Diacetin is produced under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified through comprehensive analytical testing, including assay, impurity profiling, and physical property determination. Certificates of Analysis (COA) documenting purity, identity, and key specifications are available for every batch upon request.

Storage

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