Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Conclusion on classification

For alpha-Terpineol the ecotoxicity data of Terpineol multi (a multi-constituent substance with alpha-Terpineol as its main constituent and gamma-Terpineol as the minor constituent) are used directly for classification. The other constituents of Terpineol multi are very similar in chemical structure, have similar physico-chemical properties and all belong to the neutral organics. Therefore they are expected to show similar ecotoxicity. The lowest observed acute toxicity value is a 72h ErC50 value of algae: 68 mg/L. In a chronic study in freshwater algae, a NOErC of 3.9 mg/L was observed. Alpha-Terpineol is readily biodegradable and has a log Kow of 2.6. Based on all these data, alpha-Terpineol does not need be classified according to the CLP Regulations (EC) No 1272/2008 or according to the Dangerous Substance Directive 67/548/EC (DSD).
