Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
Study performed on close structural analogue CAS No. 71786 -47 -5.
Migrated from Short description of key information:
Skin reactions were observed in response to a 50% concentration of 71786-47-5 benzenesulfonic acid mono and dialkylderivs magnesium salt, neutral, indiluents oil TBN = 20 in three of the twenty experimental animals (one grade 1 skin reaction and two observations of scaliness) in the first challenge phase. These skin reactions were not confirmed at second challenge with the same concentration. No skin reactions were observed in the control animals in response to the 50% first and second challenge exposure.
Justification for selection of skin sensitisation endpoint:
Study performed to recoginsed testing guidelines in compliance with GLP.
Respiratory sensitisation
Endpoint conclusion
- Additional information:
As determined by ECHA guidance in Appendix R. 8 -11, and considering that no data from use of the substance are available, it is not possible to assess respiratory sensitisation or estimate a threshold or DNEL.
Migrated from Short description of key information:
Respiratory sensitisation has not been assessed. There are currently no validated in vitro or in vivo data and no data available from human exposure (e.g. workers) to demonstrate or deny respiratory senitisation.
Justification for classification or non-classification
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.
