Application
1,3-Propanediol (CAS 504-63-2, PDO) is a versatile, colorless, odorless diol with excellent solvency and low toxicity. It is widely used as a humectant, moisturizer, and skin conditioning agent in cosmetics and personal care products, including creams, lotions, serums, cleansers, and deodorants. Unlike propylene glycol, it offers improved skin feel and reduced irritation. In the polymer industry, it is the key monomer for producing polytrimethylene terephthalate (PTT), a high-performance polyester used in carpets, textiles, engineering plastics, and films. It also serves as an environmentally friendly solvent for coatings, inks, cleaning agents, and antifreeze formulations. In pharmaceuticals, it functions as a solvent, carrier, and intermediate for drug synthesis. Additionally, bio-based 1,3-propanediol derived from renewable resources is increasingly preferred for sustainable manufacturing. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity 1,3-propanediol with flexible scaling from R&D to commercial tons.
