Conclusions:

The 96-h LC50 of ATLOX 3300 B (Benzenesulfonic acid, dodecyl-, compd. with 2-propanamine (1:1) ) to rainbow trout was 6.8 mg/L.

Executive summary:

The acute toxicity to rainbow trout of ATLOX 3300 B (Benzenesulfonic acid, dodecyl-, compd. with 2-propanamine (1:1) ) was tested in a 96 h aerated static test at 15 ± 1°C. The 96-h LC50 was 6.8 mg/L.

Description of key information

A range of salts have been assessed and an estimated EC50 is in the range 1 - 10 mg/l with 6.8 being used as the figure for the CSR.

Key value for chemical safety assessment
