Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 water solubility of substance is available. Therefore, the water solubility of substance was calculated using EPISUITE (v4.10) and data from LABS (CAS no: 85536-14-7). The longer carbon chain lenght, the less water soluble. The water solubility profile of substance considered to be miscible.
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.
The substance is a UVCB, therefore C11 and C16 were used as alkyl chain for QSAR calculation to cover whole constituents the substance.
EPISUITE (WSKOW v1.42) was used to determine the water solubility of H250 sulphonic acid and supporting analogue substance (LABS; CAS no: 85536-14-7). The water solubility of H250 sulphonic acid and LABS were 5.27 E-05- 0.177 mg/L and 0.22 -7.098 mg/L at 25°C, respectively. Experimental data from analogue substance was also used to support the water solubility of substance. LABS is miscible substance (16g/L). The longer carbon chain lenght, the less water soluble. The water solubility profile of H250 sulphonic acid is miscible.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.
