Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapour pressure of the test item was determined using read-across of the substance Chimassorb 2020. 

Key value for chemical safety assessment

Additional information

Data for Chimassorb 2020 indicate a low vapour pressure (7 × 10^-13 kPa at 20°C). On the base of the chemical structure, the expected vapour pressure for Uvasorb HA88 is likely to be of a similar magnitude.
