Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EBTBP is a high melting point (456 degrees C), high molecular weight (952), high Log Kow (estimated 9.2) solid  with extremely limited solubility (estimated water solubility = 3 x 10-9 mg/L; octanol solubility = 45-65 microg/L).  Substances with these characteristics are known to have poor skin penetration.   Skin penetration is required for sensistization.  Utilizing animals to verify this in the case of EBTBP is not justified.
