Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
The approach for the environmental risk assessment is described in detail under section 0.4 of IUCLID.
This endpoint summary contains the PNECS for the patchouli alcohol constituent, which represents the sesquiterpene alcohol group.
PNECaquatic has been derived from acute aquatic toxicity data performed on Patchouli Oil. Chromatographic profiles show that the water accommodating fractions used in these tests contain predominantly a single peak, which can be assigned to patchouli alcohol.Given that any low levels of hydrocarbon components present are unlikely to exhibit acute aquatic toxicity at levels up to their limit of water solubility, the patchouli alcohol component is considered the lead substance responsible for the aquatic toxicity of Patchouli Oil. Toxicity data for Patchouli Oil based on loading rates shows that fish is the most sensitive species. Therefore, the 96-hour LC50 value of 1.0mg/L based on the alcohol component of the test item has been used to derive PNECaquatic for the sesquiterpene alcohol block.
Sediment and soil PNECs have been derived from PNECaquatic using the equilibrium partitioning method.
In the absence of data for individual constituents, PNEC STP and PNEC ORAL are based on data for Patchouli oil. The PNEC STP is based on the NOEC of 100mg/L obtained from the ready biodegradability study and PNEC ORAL on the NOAEL of 277mg/kg/day from the mammalian screening study on reproduction and development.
Conclusion on classification
Not relevant for assessment entity. The conclusion for the classification of the whole substance is provided in the aquatic toxicity endpoint summary.
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).
