Description of key information

Key study: Read-across from estimated data on the two main components of the substance Reaction mass of 2,6-di-tert-butylphenol and 2,4,6-tri-tert-butylphenol. 
2,6-di-tert-butylphenol:
Using the BCFWIN v2.17 model of EPI Suite v3.20, the BCF was 434.9 (Log BCF from regression-based method = 2.638 (BCF = 434.9).
log Kow used: 4.92 (expkow database)
2,4,6-tri-tert-butylphenol:
Using the BCFWIN v2.17 model of EPI Suite v3.20, the BCF was 3282. Log BCF from regression-based method = 3.516 (BCF = 3282) log Kow used: 6.06 (expkow database)
