EC number: 904-153-2 | CAS number: -
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
- 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 logKow values of all of the major components of Reaction mass of 2-ethylpropane-1,3-diol(DMP) and 5-ethyl-1,3-dioxane-5-methanol(CTF) and propylidynetrimethanol(TMP) are reported to be <3 (see Section 4.7, partition coefficient). The logKow is below the trigger of 3 therefore the substance Reaction mass of 2-ethylpropane-1,3-diol(DMP) and 5-ethyl-1,3-dioxane-5-methanol(CTF) and propylidynetrimethanol(TMP) is not expected to bioaccumulate in living organisms. According to Column 2 of Annex IX of the REACH regulation, no bioaccumulation study is required if the logKow is below the trigger of 3.
Key value for chemical safety assessment

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
