Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Endpoint summary
Administrative data
Description of key information
The substance is considered to be corrosive to skin and will cause eye damage in view of the pH measured at ca 1 for production material
When diluted in water (solublity tests), the pH is raised so on dilution, it is quickly expected to be less corrosive to skin
Key value for chemical safety assessment
Skin irritation / corrosion
Link to relevant study records
- Endpoint:
- skin irritation / corrosion, other
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study need not be conducted because the available information indicates that the criteria are met for classification as corrosive to the skin or irritating to eyes
- the study need not be conducted because the substance is a strong acid (pH <= 2.0) or base (pH => 11.5)
- Justification for type of information:
- The substance is considered to be corrosive to skin and will cause eye damage in view of the pH measured at ca 1 for production material
When diluted in water (solublity tests), the pH is raised so on dilution, it is quickly expected to be less corrosive to skin

Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (corrosive)
