Key value for chemical safety assessment

Additional information

Propylene glycol butyl ether has a very limited potential to bio-accumulate based on a low log Kow (1.15) and bioconcentration factor (BCF). The predicted BCF for PnB is 3.16 (log BCF = 0.5), based on the results of the EPIWIN/BCF Program. Thus, derogation applies to bioaccumulation testing.
