Applicant's summary and conclusion
- Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- The substance needs to be considered as severe eye irritant, cat. 1.
- Executive summary:
Substance is listed in the consolidated version of EU Regulation 1272/2008 as corrosive, leading to a classification as serious eye damage (Cat. 1). The substance is highly reactive and hydrolyzes in contact with water or body fluids to the corresponding pyromellitic acid; measured ph-value of hydrolyzed material in water is 2. In literature, the substance is reported to be severly irritant to eyes in a standard Draize test, therefore it was decided to take over this classification and to conduct no further studies.
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.
