Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No study on surface tension of substance is available. Data from LABS (CAS no: 85536-14-7) was used as structural analogue substance for supporting substance. The surface tension of substance was determined as 35.4 mN/m. Based on the surface tension study of structural analogue, the surface tension of H250 sulphonic acid considered to be 35.4 mN/m.
Key value for chemical safety assessment
Additional information
Benzenesulphonic acid, dimethyl-,mono C14-16-alkyl derivative (H250 sulphonic acid) is a UVCB. Based on structural and functional similarities, data on Benzenesulphonic acid, 4-C10-13-sec-alkyl derivatives (LABS; CAS no: 85536-14-7) being registered under REACH, LABS Na (CAS no: 68411-30-3) being registered under REACH and LAB (CAS no: 67774-74-7) being registered under REACH are suitable as supporting study in case where specific data on the substance is lacking.
To assess the surface tension of the substance, the data of LABS (CAS No: 85536-14-7) was used as structural analogue substance.
The surface tension of LABS was measured using a harmonized ring method at 20°C according to EU guideline A.5. The surface tension was 35.4 mN/m. Based on the surface tension study of structural analogue, the surface tension of H250 sulphonic acid considered to be 35.4 mN/m.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.
