Description

Monoacetin CAS NO 26446-35-5 is a versatile glycerol monoester of acetic acid, serving as a key chemical intermediate and functional additive. Its primary value lies in its ability to act as a solvent, plasticizer, and humectant across diverse industrial processes. This product is essential for manufacturers in the chemical synthesis, polymer, and personal care industries seeking reliable, high-purity raw materials.

Application

• Chemical Synthesis: Used as an intermediate in the production of other acetins (diacetin, triacetin) and specialty esters.
• Polymer Industry: Functions as a plasticizer and solvent for cellulose-based plastics and resins, improving flexibility and processing.
• Personal Care & Cosmetics: Acts as a humectant and solvent in formulations for creams, lotions, and hair care products.
• Pharmaceuticals: Employed as an excipient and solvent in certain drug delivery systems and topical preparations.
• Tobacco Industry: Utilized as a humectant to control moisture content in tobacco products.
• Food Industry (as a precursor): Serves as a starting material for the production of food-grade emulsifiers and additives.
• Laboratory Research: Used as a reagent and standard in analytical chemistry and biochemical studies.

Quality Control

Our Monoacetin is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including chromatography and titration methods, to meet the specifications required for industrial and specialty applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment.

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 to prevent absorption of atmospheric moisture, which can affect product quality.
