Description

Dipropylene Glycol is a versatile, high-purity glycol ether widely recognized for its excellent solvent properties and low volatility. This compound is a critical intermediate and performance additive, valued for its ability to enhance product stability and functionality across numerous industrial processes. Key industries that rely on this material include personal care, coatings, chemical synthesis, and functional fluids, where it serves as a humectant, coupling agent, and reaction medium.

Application

• Personal Care & Cosmetics: Acts as a humectant, solvent, and viscosity modifier in lotions, creams, deodorants, and fragrances.
• Coatings & Inks: Used as a coalescing agent and solvent in water-based paints, lacquers, and printing inks to improve film formation and flow.
• Chemical Synthesis: Serves as a reaction intermediate and solvent in the production of plasticizers, polyester resins, and other specialty chemicals.
• Functional Fluids: Employed as a component in hydraulic and brake fluids, as well as in de-icing and heat transfer formulations.
• Adhesives & Sealants: Functions as a plasticizer and moisture-control agent to enhance flexibility and application properties.
• Cleaning Products: Utilized as a solvent and coupling agent in industrial and household cleaners for improved degreasing and stability.
