Link to relevant study records
- Endpoint:
- acute toxicity: oral
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is classified as corrosive to the skin
- other:
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Regulation (EC) No. 1907/2006 Annex VII, column 2 section 8.5 the study of acute oral toxicity does not need to be conducted since the substance is a strong acid (pH ≤ 2.0 in water) and/or the substance is classified under Regulation (EC) 1272/2008: Skin Corrosive: category 1. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.13.2, July 2017) the study does not need to be conducted. - Reason / purpose for cross-reference:
- data waiving: supporting information
Reference
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed
- Dose descriptor:
- discriminating dose
- Value:
- 2 000 mg/kg bw
- Quality of whole database:
- No study available due to the substance being classified as corrosive to the skin.
Applicant assessment on comparable substances does not indicate the substance potentially showing significant toxicity equivalent to Regulation (EC) 1272/2008: Acute Oral Toxicity - category 4 levels. A discriminating dose of LD50 oral > 2000 mg/kg bw would be expected by expert judgement in the absence of significant local toxicity (skin corrosion) following single exposure to the substance.
Acute toxicity: via inhalation route
Endpoint conclusion
- Endpoint conclusion:
- no study available
Acute toxicity: via dermal route
Endpoint conclusion
- Endpoint conclusion:
- no study available
Additional information
Justification for classification or non-classification
The substance does not meet classification criteria under Regulation (EC) 1272/2008 for acute toxicity: oral.
