Description of key information
Based on nominal concentrations, the 72-hour ErC50 values was calculated to be 0.186 mg/L whereas the ErC10 was established at 0.057 mg/L.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 0.186 mg/L
- EC10 or NOEC for freshwater algae:
- 0.057 mg/L
Additional information
The effects of TOFA_TETA_PAA_BADGE_CGE_Adduct on the growth of the unicellular green alga, Pseudokirchneriella subcapitata, were determined during a 72-hour growth inhibition toxicity test conducted in accordance with OECD Chemicals Testing Guideline No. 201 Alga, Growth Inhibition Test (adopted 23 March 2006) (Annex 5 corrected 28 July 2011). All validity criteria were met therefore the test was considered valid. Based on nominal concentrations, the 72-hour EyC50 and the 0-72 hour EbC50 and ErC50 values were calculated to be 0.077, 0.073 and 0.186 mg/L, respectively. The corresponding NOEC values for yield, biomass and specific growth rate after 72 hours were 0.32 mg/L and EC10 values were 0.035, 0.039 and 0.057 mg/L accordingly. Under the conditions of this test, TOFA_TETA_PAA_BADGE_CGE_Adduct was considered to inhibit the growth of Pseudokirchneriella subcapitata at nominal concentrations greater than 0.032 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
