Description

Alpha, ω-Dipropionic Acid Dodecaethylene Glycol is a high-purity, non-ionic surfactant intermediate characterized by its long polyether chain terminated with carboxylic acid groups. This unique bifunctional structure provides excellent solubility, emulsifying properties, and reactivity, making it a versatile building block for advanced material synthesis. It is primarily utilized by formulators and chemical manufacturers in the personal care, pharmaceutical, and specialty polymer industries seeking to create custom-tailored surfactants, emulsifiers, and polymeric materials.

Application

• Surfactant & Emulsifier Synthesis: A key intermediate for producing high-performance, low-irritation surfactants and emulsifiers used in premium personal care products (e.g., shampoos, creams, lotions).
• Polymer Modification: Acts as a reactive monomer or chain extender for synthesizing and modifying polyesters, polyurethanes, and other specialty polymers to impart hydrophilicity and flexibility.
• Pharmaceutical Excipients: Used in the development of drug delivery systems, such as polymeric micelles and nanoparticles, to enhance drug solubility and bioavailability.
• Lubricant & Metalworking Fluid Additives: Serves as a precursor for creating additives that improve lubricity, corrosion inhibition, and emulsion stability in industrial fluids.
• Textile & Fiber Processing: Employed in the manufacture of fiber lubricants, spin finishes, and dyeing auxiliaries to improve processing efficiency and fiber quality.
• Adhesive & Sealant Formulation: Incorporated to modify the properties of adhesives and sealants, enhancing their flexibility, adhesion, and water resistance.
