Typical Properties

1,3-Propanediol Usage

• Polymers & High-Performance Materials:

  • Polytrimethylene Terephthalate: Serves as the critical monomer for synthesizing PTT polyester resin, producing high-elasticity, stain-resistant fibers, carpets, apparel, and engineering thermoplastics.

  • Polyurethanes & Unsaturated Polyester Resins: Used as a chain extender and diol monomer in polyurethane (PU) elastomers, coatings, adhesives, and unsaturated polyester resins (UPR).

• Cosmetics & Personal Care:

  • Natural Humectant & Carrier Solvent: Widely used as a bio-based humectant and solvent in skincare formulations, lotions, serums, and hair care products, providing long-lasting hydration with zero stickiness.

  • Preservative Booster: Enhances the efficacy of antimicrobial and preservative systems, allowing reduced dosage of synthetic preservatives.

• Pharmaceuticals, Flavors & Functional Fluids:

  • Pharmaceutical Carrier & Extractant: Used as a solvent for active pharmaceutical ingredients, oral liquids, and plant botanical extraction.

  • Heat Transfer Fluids & Deicing: Utilized in eco-friendly heat transfer fluids, engine coolants, and deicing formulations due to its low toxicity and favorable thermophysical profile.
