Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A reliable (Klimisch 1) short-term toxicity study with fish have been conducted HQEE and is included in this dossier.
Lawrence and Hirsch (1995) conducted a reliable (Klimisch 1) GLP compliant study following OECD 203 methodsFathead minnows (Pimephales promelas) were exposed to HQEE at measured concentrations of control, 84.7, 169.2, 311.4, 566.0, and 1044.7mg/L for replicate A and 87.2, 167.3, 314.2, 574.8, and 1043.7 mg/L for replicate B under static conditions. The 96-h LC50 was >1044 mg/L, based on mortality.
Adequate reliable measured data exists for short-term toxicity to fish for HQEE and has been documented within this dossier. The most reliable study result for the test substance has been identified as a study Lawrence and Hirsch (1995) which reports an LC50 for short term toxicity in fish of >1044 mg/L. Consequently this value will be taken as the short-term toxicity in fish endpoint for HQEE.
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.
