Description of key information

The measured water solubility of BBP is 2.69 mg/L at 25°C. The interpretation of this result is that BBP is slightly soluble.

Key value for chemical safety assessment

Water solubility:
2.69 mg/L

25 °C

Additional information

The measured value for this endpoint was obtained from the key study of Howard et al, 1985. The peer-reviewed handbook of Yalkowsky and He, 2003, (which cites a value of 2.7 mg/L) forms our second key study for this endpoint. These values are supported by two further studies. The results from all four sources are consistent with each other and mean that BBP should be considered to be slightly soluble.
