Reference
Description of key information
There are two available studies performed both on Acid Yellow 23 and on another form of this dye.
Key value for chemical safety assessment
Fresh water invertebrates
Fresh water invertebrates
- Effect concentration:
- 125 mg/L
Additional information
The key study has been performed for different concentration and based on the active ingredient a value of EC50 > 125 mg/l has been established.
Based on the criteria of the CLP Regulation (EC n. 1272/2008), the substance does not required the classification for environment.
