Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Pine scotch oil is a Natural Complex Substance (UVCB) with a well-defined composition for which the relative percentage and its reported variation of each constituent is known.

Therefore, it has been decided that the ecotoxicity of Pine scotch oil will be derived from knowledge of the constituents. The mixture ecotoxicity properties may be derived from the ecotoxicity of the individual constituents (as reported in endpoint summary discussions for each species).


Short-term toxicity to fish is provided in the dataset even if the tonnage band (1 -10 tonnes/year) does not require that endpoint. Indeed that endpoint is fulfilled according to environmental classification rules. Classification should be derived from the most sensible species. Because toxicity data have demonstrated the lowest LC50 values for constituents, it has been decided to calculate fish L(E)C50, in order to ascertain the classification for environment of Pine scotch oil.

Acute toxicities to aquatic organisms property have been investigated using an in-house calculation method that replaces OECD 201, 202 and 203 studies and guideline for Testing of Chemicals No. 23 (i.e. WAF conditions). Two compositions have been investigated, the “typical” composition proposed in the SIP and a theoretical worst case composition derived from data supplied in the SIP that maximizes the concentration of the most toxic constituents.

Using these worst case composition ecotoxicity results are as follow:

-         Fish: 96-h LL50 was 2.8 mg test material/L

-         Invertebrate: 48-h EL50 was 2.5 mg test material/L

-         Algae: 72-h ErL50 was 7.1 mg test material/L

Based on these results, Pine scotch oil would not be classified as acute 1 to aquatic organisms in accordance with the classification of the CLP.
