Endpoint:
bioaccumulation in aquatic species: fish
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Description of key information

The weighted average log Pow of reaction mass of 2-ethyl-2 -(methoxymethyl)-propane-1,3-diol and 2 -ethylpropane-1,3 –diol is reported to be 0.42 (see Section 4.7, partition coefficient).  According to Column 2 of Annex IX of the REACH regulation, no study is required if the log Kow is below the trigger of 3 as the substance can be expected to have a low potential for bioaccumulation. Given this the potential for aquatic bioaccumulation is low and further information is not required.

Key value for chemical safety assessment
