Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The toxicokinetics of 2,2’oxydiethanol and of propane-1, 2-diol and its propoxylated oligomers have been examined in Illing and Barrat (2007 revised 2009). Propane-1, 2-diol is both a core substance (initiator) and a repeating unit. The information on the toxicokinetics of 2,2’-oxydipropanol, propoxylated, 1-4.5 mol (the NLP polyol) is based on the information for ethane-1,2-diol and its dimer (2,2’-oxydiethanol) and trimer and propane-1,2-diol and its dimer (1 mol propoxylated propane-1,2-diol) and trimer (2 mol propoxylated propane-1,2-diol). Oxydiethanol has two hydroxy groups, thus oligomers are considered to be core substances with chains of between one and three repeating units. Commercial material contains a range of propoxylated oxydiethanols.
