Dermal: LD50: > 2000 mg/kg bw for rat

Key value for chemical safety assessment

Acute toxicity: via oral route

Endpoint conclusion
Dose descriptor:
LD50
2 000 mg/kg bw

Acute toxicity: via dermal route

Endpoint conclusion
Dose descriptor:
LD50
2 000 mg/kg bw

Additional information

Two toxicological studies were performed with the registered substance, following the OECD Guideline 423: acute oral toxicity – acute toxic class method and OECD Guideline 402: acute dermal toxicity, in a certified GLP lab. So the reliability of this data can be ranked as klimisch code 1: reliable without restrictions. On the basis of this analysis, those studies can be chosen as the key studies.

Justification for classification or non-classification

According to Official Journal of the European Union 1272/2008 (CLP) dated December 16th 2008, tartaric acid is non-classified in the acute toxicity hazard categories. But it needs to be emphasized that tartaric acid is classified in category 5 of acute oral toxicity in the GHS classification system.
