Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Various studies covering short- and long-term exposure of all three taxonomic groups (fish, crustacea, algae) as well as a STP toxicity study were available. Due to the low water solubility of the substance in several studies acetone, respectively DMF, as a disperser was used.
In all three short-term studies no threshold concentration could be determined as no effects were observed up to the highest concentration used in the tests. In the available long-term studies with fish (OECD 210) and Daphnids (OECD 211) a NOEC of 1.6 µg/L, respectively 36 µg/L (nominal), were observed.
Toxicity to STP microorganisms was examined in a study according to OECD guideline 209 showing a low toxicity (NOEC (30 min) > 202 mg/L). However, the observed NOEC was stated as nominal concentration exceeding the water solubility of 2 -(phenylmethoxy)naphthalene by far.
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.
