Short-term toxicity to fish
Administrative data

Description of key information
The 96-hour LC50 was >1000 mg/l and is therefore considered to be non-toxic to fish at its limit of solubility.
Key value for chemical safety assessment
Additional information
Short term toxicity to fish studies have been conducted for Santicizer 261A but have not been available for review. A study using Rainbow trout was conducted by ABC Laboratories in 1980 and described in a 2006 American Chemistry Council report. There were sufficient details for an assessment to be made. The study reported an LC50 of >1000 mg/L and concluded that Santicizer 261A was non-toxic to Rainbow trout at its water solubility.
Two short term toxicity tests to fish were conducted using the very closely related phthalate Santicizer 278 (CAS RN: 16883 -83 -3), and were used as supporting studies for this endpoint. The reported 96-hour LC50 for Rainbow trout (Analytical Bio Chemistry Laboratories Inc, 1979) was >1000 mg/l (at 12°C), and for Fathead minnows (Analytical Bio Chemistry Laboratories Inc, 1979) also >1000 mg/l (at 22°C). In both tests the concentration used was 1000 mg/l. This concentration was determined by range finding tests to be appropriate as mortalities did not occur below this concentration
This concentration exceeds the solubility of the test compound (0.0015 mg/l at 25°C) but since no mortalities occurred even at this concentration, Santicizer 278 is considered non-toxic to fish at its limit of solubility. Due its structure and properties Santicizer 261A would be expected to give similar results.
Santicizer 261A is therefore considered to be non-toxic to fish at its limit of solubility based on experimental data, read-across and calculated data.
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.
