Endpoint summary
Administrative data
Description of key information
One key study is available for each of the following endpoints:
Aquatic invertebrates acute
The acute toxicity (inhibition of mobility) of the test item tert-pentyl 2-ethylperoxyhexanoate to aquatic invertebrates for a duration of 48 hours was assessed according to the OECD Guideline 202 and GLP requirements. Daphnia magna were exposed under static conditions: 48h-EC50= 3.7 mg/L
Aquatic invertebrates chronic
In the 21-day semi-static chronic toxicity test (OECD 211) to Daphnia magna performed on the closely related substance tert-butyl peroxy-2-ethylhexanoate (3006-82-4) the 21-day NOEC value based on reproduction was determined to be 0.45 mg/L.
Algae
The determination of the growth inhibition of the freshwater algae Pseudokirchneriella subcapitata exposed to the test item tert-pentyl 2-ethylperoxyhexanoate for a duration of 72 hours was assessed according to the OECD Guideline 201: ErC50-72h= 0.28 mg/L & ErC10-72h= 0.023 mg/L (based on growth rate)
Microorganisms
The toxicity of TERT-AMYL PEROXY-2-ETHYLHEXANOATE to microorganism was estimated in a study performed according to OECD 209 guideline and GLP requirements.EC50 for the test item was determined to be higher than the highest tested concentration: EC50 > 1000 mg/L
Fish - Acute
The closely related substance tert.-Butylperoxy-2-ethylhexanoat was tested for acute toxicity to fish according to EU-method C.1 (1984) and OECD guideline 203 (1984). In this 96-hour semi-static acute toxicity test with Poecilia reticulata (guppy) the LC50 value was 8.66 mg/L. This is supported by an FET study on 686-31-7 indicating that a fish LC50 would be expected in the range 1-10 mg/L.
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.
