Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 measured half-life of CHPTAC at pH 7.8 and 12°C was 21 days.
Key value for chemical safety assessment
Additional information
The reaction of CHPTAC with water is more complex than a simple first order hydrolysis reaction. In a standard hydrolysis test conducted according to EC Test Method C.7 the half-life at 35 °C and pH 7 was 3.75 days. Extrapolating to environmental conditions (12 °C) the corresponding half life is predicted to be 75.5 days. However, other evidence suggested that true reaction rates under neutral conditions were faster than this, therefore a study was performed under environmentally relevant conditions (Raisio, 2004). In this study the measured half-life of CHPTAC at pH 7.8 and 12°C
was 21 days.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.
