Additional information
Conclusion on classification
According to CLP Regulation, butylal is not classified for its toxicty to aquatic organisms:
a) Acute aquatic hazard: butylal is not classified with EC-LC50 > 1 mg/L
b) Long-term aquatic hazard: as adequate chronic toxicity data are available for the 3 trophic levels, butylal is not classified with NOEC > 1 mg/L (for non-rapidely biodegradable substance)
