1,3-propanediol

Harm score: 2 (Derivatives of natural substances)

1,3-propanediol, also known as PDO, is an important organic compound characterized by its ability to form rigid and flexible structures, resulting in a wide range of applications. It occurs in its unused form as a colourless liquid with a slightly sweet taste. Chemically, it is a type of diol, an organic compound containing two hydroxyl groups. Because of its unique chemical structure, 1,3-propanediol can be synthesized from a variety of sources, including petroleum derivatives, but also from renewable raw materials such as corn or soy.

In industry, 1,3-propanediol is used in a wide range of products. Among the best known are its uses in the production of polytrimethylene terephthalate (PTT), a type of polyester used in the textile industry, but also in the automotive industry for interior parts such as car seats, floor coverings and carpets. In addition, 1,3-propanediol is also used in the production of polyurethane, resins and plastics. These are mainly products that require high durability and flexibility. Furthermore, PDO is used in cosmetics and body care, specifically in skin creams, sunscreens, shampoos and conditioners. Finally, it is also used in the food, pharmaceutical and electronics industries. The use of this versatile diol is therefore very wide indeed.
