Endpoint summary
Administrative data
Description of key information
The assessment of irritation / corrosive properties of the substance has been made on the basis of high alkalinity (pH > 11.5) and corrosive properties of the constituents.
Key value for chemical safety assessment
Skin irritation / corrosion
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (corrosive)
Eye irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Respiratory irritation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (irritating)
Additional information
According to Regulation EC 1272/2008 Annex 1 Chapter 3.2.3.1.2., a mixture is considered corrosive to skin (Skin Corrosive Category 1) if it has a pH of 11.5 or greater. Moreover, over 5% of the known constituents are classified as corrosive. Also, according to Chapter 3.2.2.4., e.g. caustic alkalis with extreme pH shall be considered as skin corrosives.
Effects on skin irritation/corrosion: highly corrosive
Effects on eye irritation: highly corrosive
Effects on respiratory irritation: irritating
Justification for classification or non-classification
Classification is required under Directive 67/548/EEC and under Regulation EC 1272/2008 for skin, eye and respiratory tract corrosion / irritation. Skin corrosive: pH > 11.5, alkalic constituents. Eye corrosive: pH > 11.5, alkalic constituents. Respiratory irritation: pH > 11.5.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
