Description of key information
The toxicity of DMSO to microorganisms has been investigated in relevant studies compliant with guideline studies or other methods, and in not relevant studies.
Toxicity studies, carried out according ISO guidelines, reveal a 30 min EC50 between 10 and 100 mg/L for activated sludge. For Pseudomonas putida, EC10 - 16h determined was of 7100 mg/L and EC50 - 16h was of 16000 mg/L. Another study published determined the toxicity of DMSO to Photobacterium phosphoreum, and EC10 - 5min determined was of 77 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 10 mg/L
- EC10 or NOEC for microorganisms:
- 77 mg/L
