Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The LC50 (96h) of p-HBA in the short term toxicity key study (Toray 1997) was higher than 100 mg/l with pH-neutralisation of the test media. The LC50 (96h) of p-HBA without pH-neutralisation was 92.8 mg/l. pH within this study was between 4.0 and 4.2 in the highest concentration exhibiting effects. Thus, the pH was outside the acceptable range for validity. It can be expected that the effects are mainly due to the low pH, which leads to an unphysiological milieu. Therefore, this value will not be used as key value for hazard assessment.

Additional information
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.
