Aquatic bioaccumulation

It is generally assumed that non-ionised organic substances with a log Kow below 3 are not significantly bioaccumulative (refer Section R7c of the ECHA Guidance on information requirements).

The estimated log Kow forMineral Paraffin Oilcomponents are above this threshold value.

Generally, a BCF in fish of ≥ 500 is indicative of the potential to bioconcentrate for classification purposes in accordance with CLP/GHS criteria.


The BCF values estimated forMineral Paraffin Oil componentssuggest some bioaccumulation potential for some ofMineral Paraffin Oilcomponents.
