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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Test is waived on the basis that no effects would be expected as concentrations at the limit of solubility occur naturally in the environment and it is a substance of plant origin.
Key value for chemical safety assessment
Additional information
Concentrations of plant sterols are considered with reference to the key marker substance β-sitosterol, which is the major constituent by weight in plant sterols as registered. Measured concentrations of β-sitosterol in the environment are consistent with its ubiquitous essentiality in plant matter. Wash-off from soil into surface water is a natural and unavoidable process which can give rise to concentrations of the order of 1 μg/L (the limit of water solubility is estimated at 0.00055 mg/l). It is therefore considered that no long-term effects on aquatic organisms would be expected, due to the ubiquitous presence of the substance at the limit of its solubility in the natural environment.
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.
