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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables
The potential environmental distribution of tripropylene glycol was obtained from a generic fugacity model, Mackay level III. The
results show that when 1,4- is released into water, the majority of the chemical is likely distributed into soil and sediment.
PECs have been calculated based on several models (MNSEM, CHEMCAN, CHEMFRN) considering its physico-chemical properties (e.g. molecular weight, water solubility, vapour pressure and partition coefficient). The estimated concentrations of MNSEM
model w ere 9.7 E-11 mg/l (air), 8.3 E-6 mg/l (water), 3.0 E-5 mg/kg (soil), 5.0 E-5 mg/kg (sediment).
Steady state mass and concentration calculated using MNSEM 147S:
Air: 9.7E-11 mg/l
Water: 8.3E-06 mg/l
Soil: 3.0E-05 mg/kg dry solid
Sediment: 5.0E-05 mg/kg dry solid
Input data:
Molecular weight: 192.26
Water solubility: 1000000 [mg/l]
Vapor pressure: 1.05E+00 [mmHg]
Log Pow: 0.60
Applicant's summary and conclusion
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.
