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.
