Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The estimated Henry's law coefficient of the read across substance amides, C18(unsatd.), N,N-bis(hydroxyethyl) of 0.00000101 Pa-m3/mole is considered to be low. Based on read-across these values will be used for the assessment of HE Rape Oil, reaction product with diethanolamine.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 25 °C
Additional information
The Henry’s law constant (HLC) of the read across substance amides, C18 -unsatd., N,N-bis(hydroxyethyl) was estimated by HENRYWIN v3.20 using bond contribution method.
This method uses valid Bond contribution values, which are determined for 59 chemical bonds by a least-square analysis of HLCs for 345 organic compounds.
The value of the HLC for the test substance was finally calculated on a weighted-average basis using the mole fractions of the individual components.
The estimated HLC value was found to be 9.97 x 10(-12) atm-m3/mole (0.00000101 pa-m3/mole).
Based on read-across these values will be used for the assessment of HE Rape Oil, reaction product with diethanolamine.
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.
