Dodecaethylene Glycol (CAS: 6790-09-6), a member of the polyethylene glycol family, is a high molecular weight oligomer with significant utility across various industrial sectors. Its distinctive structure, featuring twelve repeating ethylene oxide units terminated by hydroxyl groups (HO-PEG12-OH), imparts unique chemical and physical properties. Understanding these characteristics is crucial for procurement managers and chemists looking to source this valuable compound. As a specialized manufacturer and supplier in China, we provide insights into the chemistry and industrial applications of Dodecaethylene Glycol.

Chemical Synthesis and Properties
Dodecaethylene Glycol is typically synthesized through the controlled polymerization of ethylene oxide. This process allows for the creation of PEG chains with specific lengths and defined end-groups. The hydroxyl functionalities at both ends of the Dodecaethylene Glycol molecule make it a homobifunctional linker, capable of reacting with a wide range of chemical moieties. Its properties include:

  • Appearance: Typically a white to orange or green wax-like solid at room temperature, with a melting point around 38°C.
  • Purity: High purity grades, often exceeding 95% (GC or HPLC), are essential for its demanding industrial applications.
  • Solubility: Highly soluble in water and many organic solvents, contributing to its versatility in various formulations.
  • Reactivity: The terminal hydroxyl groups can be readily activated or derivatized for conjugation, esterification, etherification, and other chemical reactions.

Key Industrial Applications
The versatility of Dodecaethylene Glycol makes it a sought-after chemical in several industries:

  • Surfactant Formulations: Its amphiphilic nature, when incorporated into more complex structures, allows it to function as an effective surfactant, emulsifier, and dispersant in cleaning products, cosmetics, and industrial processes.
  • Polymer Synthesis: Dodecaethylene Glycol serves as a comonomer or building block in the synthesis of various polymers, including polyesters, polyurethanes, and specialty coatings, imparting flexibility and hydrophilicity.
  • Pharmaceuticals: Beyond drug delivery, it's used as an excipient, solubilizer, or stabilizer in drug formulations, contributing to the overall performance of medications.
  • Cosmetics and Personal Care: Its humectant and emollient properties make it valuable in skincare products, lotions, and creams for moisture retention and improved texture.
