1,3-Propanediol, also propane-1,3-diol or trimethylene glycol, is a three-carbon diol. It is a clear colorless viscous liquid that is miscible with water and ethanol.[1]
1,3-Propanediol can be formulated into a variety of industrial products including composites, adhesives, laminates, coatings, moldings, novel aliphatic polyesters (such as polytrimethylene terephthalate), copolyesters, solvents, antifreeze and other end uses.
1,3-Propanediol does not appear to pose a significant hazard via inhalation of either the vapor or a vapor/aerosol mixture.[2]
Currently 1, 3 Propanediol is being produced by Dupont Tate & Lyle Bioproducts, a joint venture between DuPont and Tate & Lyle, in Loudon, Tennessee. Dubbed Bio-PDO, it's being produced with genetically modified strain of e-coli that's fed a refined corn syrup. The bacteria, after a fermentation process, then produces Bio-PDO. Most in the industry refer to Bio-PDO as "Liquid Diamonds", due to the crystal clear liquid that is the final product.
