Additional information:
Migrated from Short description of key information:
No animal test data available; the substance and its degradation product are corrosive.

Justification for selection of skin sensitisation endpoint:
The degradation product, phosphoric acid are classified as a skin corrosive substance category 1B (concentration > or = 25%) according to the CLP Regulation Annex VI, table 3.1 (EC Regulation 1272/2008 on classification, labeling and packaging of substances and mixtures).

Respiratory sensitisation

Endpoint conclusion
Endpoint conclusion:
no study available

Justification for classification or non-classification
