Endpoint conclusion
- Additional information:
- Migrated from Short description of key information:
- In vivo testing of skin sensitation is not required if the substance is to be classified for skin corrosivity or it is a strong base (pH >11.5) ( REACH Regulation No 1907/2006 Annex VII). According to the results of an in vitro study for skin corrosion/irritation (Key study Maier 2010. Epiderm Skin Corrosivity/Irritation Test) Black liquor is considered to be non-corrosive and irritant to skin, but based on the estimation of the maximum expected concentration the of the main of components of Black liquor it should be classifed as corrosive.
- Additionally the pH of the tested Black liquor was 13.7. Therefore skin sensitisation test is not relevant for Black liquor.
Justification for classification or non-classification
Classification of Black liquor as such for skin sensitisation is not possible due to lack of sufficient human and animal data on Black liquor and/or its components.
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.
