Basic Information

• Chemical Name : Dipropylene Glycol Dimethyl Ether (DPGDM)
• CAS Number : 34590-94-8
• Molecular Formula : C 8 H 18 O 3
• Molecular Weight : 162.23 g/mol
• Class : Polyether solvent, belongs to glycol ether derivatives.

1. Paint and Coating Industry
   • Solvent and Coupling Agent :
     • Used in water-based coatings (e.g., acrylic, epoxy) to enhance miscibility between water and organic resins, reducing surface tension and improving film uniformity.
     • As a coalescing agent in latex paints, lowering the minimum film-forming temperature (MFFT) for better adhesion at low temperatures.
   • Solvent-Based Coatings :
     Regulates evaporation rates in alkyd, polyurethane, and nitrocellulose coatings to prevent "blushing" (moisture-induced defects).
2. Printing Inks
   • Improves pigment wetting and ink flow in flexographic/gravure inks, especially for plastic and paper substrates.
   • Reduces odor in low-VOC inks, suitable for food packaging applications.
3. Cleaning Agents
   • Industrial cleaning: Effectively dissolves oils, greases, and resin residues in precision electronics, metal parts, and optical components.
   • Household cleaners: Used in high-performance degreasers and glass cleaners due to its low odor and good water solubility.
4. Personal Care and Cosmetics
   • Solvent in skincare products (e.g., creams, lotions) to enhance active ingredient dispersion.
   • Used in nail polishes and hair sprays to regulate texture and drying speed (low toxicity, compliant with cosmetic safety standards).
5. Agriculture and Pharmaceuticals
   • Solvent for pesticide emulsions and pharmaceutical intermediates, ensuring stable formulations.
   • Extraction solvent in herbal medicine processing.
6. Polymer Processing
   • Plasticizer auxiliary in polymer synthesis to improve processability and flexibility of resins (e.g., PVC, PS).

• Advantages :
  • Low Toxicity : Generally recognized as safe (GRAS) for indirect food contact applications (e.g., FDA compliance).
  • High Solvency : Effective for polar and nonpolar substances, ideal for formulating multi-component systems.
  • Eco-Friendly : Low VOC content, biodegradable in part (reduced environmental impact compared to traditional glycol ethers).
• Safety Data :
  • Acute Toxicity : Oral LD 50 (rat) >5,000 mg/kg (practically non-toxic).
  • Irritation : Minimal skin/eye irritation; no significant respiratory hazards at normal use concentrations.
  • Protective Measures : Use in well-ventilated areas; avoid prolonged skin contact (gloves recommended for industrial handling).

• Storage :
  Store in sealed steel or HDPE containers in a cool, dry place, away from oxidizing agents.
• Shelf Life :
  3-5 years unopened; after opening, reseal promptly to prevent moisture absorption.
• Transportation :
  Not classified as a hazardous material under IATA/IMO (non-flammable in small quantities), but follow local regulations for bulk transport.
