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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 232-350-7 | CAS number: 8006-64-2 Any of the volatile predominately terpenic fractions or distillates resulting from the solvent extraction of, gum collection from, or pulping of softwoods. Composed primarily of the C10H16 terpene hydrocarbons: α-pinene, β-pinene, limonene, 3-carene, camphene. May contain other acyclic, monocyclic, or bicyclic terpenes, oxygenated terpenes, and anethole. Exact composition varies with refining methods and the age, location, and species of the softwood source.

Description of key information
No measured data are available for long-term toxicity of TOPP to aquatic invertebrates. The long-term toxicity of the constituents of TOPP to invertebrates will be assessed later based on ECHA communication/decision number CCH-D-2114519392-52-01. In the interim, TOPP is a UVCB substance and the study does not need to be conducted because the needs associated with obtaining a sound understanding of long-term toxicity to invertebrates are adequately met by the available data on constituents. Compositional information has been used in conjunction with validated QSARs to derive No Observed Effect Concentrations (NOECs) for TOPP constituent blocks. Calculation of PNECs for the aquatic compartment will be based on the block NOECs rather than on data for the whole substance. Testing for long-term toxicity to invertebrates will therefore not contribute to the database that is required to complete the assessment of the substance.
NOEC values of 0.0025 and 0.46 mg/l have been reported for the effects of dimethyl disulfide (CAS 624-92-0) to Daphnia magna and Americamysis bahia.

Additional information
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.
