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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
Based on the result of the octanol/water partition coefficient (Log Kow of -0.64) dipropylene glycol is expected to have a low potential for adsorption/desorption.
The Koc value calculated from the octanol-water partition coefficient (log Kow = -0.64) using the equation from the TGD (non-hydrophobics) is 4.87 (log value = 0.69).
The Henry's law constant at environmental relevant temperature is 9.07E-04 Pa.m3/mol using EUSES calculation.
If released into the environment, dipropylene glycol will preferentially partition into water (46.1%) and soil (53.7%) (Mackay, 1999). Volatility is not expected to be a significant fate process due to its low vapor pressure and high water solubility.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
