Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

Endpoint:
distribution modelling
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Adequacy of study:
supporting study
Study period:
2010-04-13
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Accepted calculation method with acceptable restrictions: Preference of aqueous media will be further increased by neutralization as this increases the water solubility.

Applicant's summary and conclusion

Conclusions:
According to Mackay Level l model calculations, the main target compartment for dodecanedioic acid, the read-across chemical for Corfree® M1, will be water (79.4%), sediment (10.3%) and soil (10.2%). The air compartment is not expected to be relevant.
