Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 close to the PEC occur naturally in the environment.

Key value for chemical safety assessment

Additional information

Plant sterols occur naturally in the environment. 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.  As a lipophilic substance it will adsorb to the organic matter present in suspended and bottom sediments. Therefore it is consistent with its properties to find measurable concentrations in sediments, with 1 mg/kg being typical.
