Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 solubility in water is not a constant but increases with the mass of test item applied in the experiment. This is because the
test item is a mixture. Every constituent contributes to a different degree to overall solubility, depending on its own individual solubility
and its mass fraction in the test item. Therefore, results depend on the proportions of test item and water used in the respective
experiment.
The measured values are higher (100-1000 times) than the theoretically calculated values.
(Beta Santalene, CAS: 511 -59 -1; 0.02577 mg/l at 25 °C, estimated from Kow WSKOW v. 1.42)
(Alpha Santalene, CAS: 512 -61-8; 0.02577 mg/l at 25 °C, estimated from Kow WSKOW v. 1.42)
lt may be possible that the measured values are the result of overestimation of the aqueous concentration due to formation of
microdroplets of test item in the aqueous phase.
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.
