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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is hydrolytically unstable at pH 4, 7 and 9 (half-life less than 12 hours)
Reference
Description of key information
The value of 0.1 ug/L has been used to calculate the predicted exposure.
According to coloumn II, Annex VII Requirements 7.7. The study does not need to be conducted since the substance is hydrolytically unstable at pH 4, 7 and 9.
Tetrahydroxylane is not stable at pH 4,7 and 9, since it polymerize. Therefore it is placed on the market in a water/PEG solution at very low acid pH (about 0.6) in order to mantain the undissociate form.
Key value for chemical safety assessment
- Water solubility:
- 0.1 µg/L
- at the temperature of:
- 25 °C
Additional information
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.
