Endpoint summary
Administrative data
Description of key information
In accordance with ANNEX VII column 2 of the REACH regulation the study need not be conducted if the substance is a strong acid (pH<=2.0) or strong base (pH=> 11.5).
The experimental pH of the test chemical was 1.77, which is highly acidic in nature. This is suggestive of the test chemical being highly corrosive and damaging to skin. Hence, the in vivo and in vitro skin sensitization studies were considered for waiver.
Key value for chemical safety assessment
Skin sensitisation
Link to relevant study records
- Endpoint:
- skin sensitisation: in vitro
- 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 a strong acid (pH ≤2.0) or base (pH =>11.5)
- the study does not need to be conducted because the substance is classified as skin corrosion (Category 1, 1A, 1B or 1C)
- Endpoint:
- skin sensitisation: in vivo (LLNA)
- 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 a strong acid (pH ≤2.0) or base (pH =>11.5)

Endpoint conclusion
- Endpoint conclusion:
- no study available
Justification for classification or non-classification
The experimental pH of the test chemical was 1.77, which is highly acidic in nature. This is suggestive of the test chemical being highly corrosive and damaging to skin.
According to the CLP Regulation (EC n. 1272/2008) and based on the low pH (pH= 1.77) of the test chemical, the classification Skin Sensitizer 1 is proposed for the test chemical
