Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PPP-BP was found to be hydrolytically stable at pH 4, pH 7, and pH 9, as defined by OECD Guideline 111 (OECD, 2002), i.e., less than 10 % loss of PPP-BP was observed after heating for 5.7 days, indicating that the hydrolytic half-life of PPP-BP at these pHs was greater than 1 year at 25°C.

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
25 °C

Additional information

Based on the HPLC-UV analytical results, PPP-BP was found to be hydrolytically stable at pH 4, pH 7, and pH 9, as defined by OECD Guideline 111 (OECD, 2002). As this indicated less than 10 % loss of PPP-BP after heating for 5.7 days, the hydrolytic half-life of PPP-BP at these pHs can be considered to be greater than 1 year at 25°C.
