Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Key value for chemical safety assessment
- Relative density at 20C:
- 1.17
Additional information
In order to estimate the relative density of the substance sulfuric acid, mono-C8-14 alkyl esters, ammonium salts, compds. with triethanolamine (CAS No. 96690-74-3), the results obtained experimentally for sulfuric acid, mono-C8-14 alkyl esters, ammonium salts (CAS No. 90583-10-1) and for sulfuric acid, mono-C8-14 alkyl esters, compound with triethanolamine (CAS No. 85665-45-8) are used in a weight of evidence approach. The two read-across substances can be seen as complementary to each other, providing both counter ions present in the target substance. The measured relative values are to a good approximation equal (1.173 for 90583-10-1 and 1.171 for 85665-45-8) and both can be rounded to 1.17, which is the value accepted to be used for a chemical safety assessment.
The relative density of both analogue substances was determined by pycnometer method according to OECD Guideline 109.
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.
