Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
According to column 2 of REACh Annex IX and X, tests on short- and long-term toxicity to terrestrial organisms do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
If no data on the toxicity to soil organisms are available and direct or indirect exposure cannot be excluded, it is proposed in the CSA Guidance Document, Chapter R.7c, Section 7.11 (Figures R.7.11-2 and R.7.11-3) to gather existing information suitable for a classification of the chemical of interest into a “soil hazard category” and conduct a screening assessment (according to table R.7.11-2):
•Since benzyl alcohol is readily biodegradable and considering the low distribution coefficient Koc of 15.7 and the low logPow of 1.1, high adsorption or high persistence of benzyl alcohol in the soil can be excluded. In addition, several acute aquatic studies in three trophic levels (fish, daphnid, algae) and long-term studies in two trophic levels (daphnid and algae) indicate that benzyl alcohol has a low acute toxicity to aquatic organisms. Hence, benzyl alcohol can be classified into soil hazard category 1.
•Since benzyl alcohol is classified into soil hazard category 1, the chemical safety assessment can be calculated using the equilibrium partitioning method (EPM). Based on the PNECwater of 1 mg/L, the PNECsoil for benzyl alcohol is calculated to be 0.456 mg/kg soil dw. In the chemical safety assessment no risk to the terrestrial compartment is identified for all relevant uses (PEC/PNEC values < 1), so that no refinement of the PNECsoil organisms is required.
It can be concluded for all relevant uses considered here that the risk for the terrestrial compartment is low and further information and testing is not needed.
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.
