Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
A toxicokinetic assessment for Di C8–C10, branched, C9-rich, Alkylnaphthalene Sulphonic Acid (DNNSA), a key analogue of NH4DNNSA, has been made based on the physical and chemical properties of the substance, the available toxicity studies and the QSAR model BCFWIN/BCFBAF (EPIWIN Suite).
Key value for chemical safety assessment
- Bioaccumulation potential:
- low bioaccumulation potential
- Absorption rate - oral (%):
- 100
- Absorption rate - dermal (%):
- 10
- Absorption rate - inhalation (%):
- 10
Additional information
The oral absorption for risk assessment purposes of DNNSA is set at 100%, whereas inhalative and dermal absorption is set to 10%. Once absorbed, wide distribution of the test substance throughout the body is not expected based on its low water solubility and molecular size. Based on the high log P and the results of QSAR modeling, DNNSA is not expected to significantly bioaccumulate in animal tissue.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
