Description of key information
The registered substance is produced, supplied and marketed in the presence of a liquid mineral oil solvent. Removal of this solvent is expected to cause a change in the equilibrium of the chemical structure of the alkaryl benzene sulfonates resulting in a degradation of the chemical structure to a structure that is not representative of the substance being placed on the market in the EU. It is, in consequence, not possible to undertake any study of the registered substance in the absence of the solvent. This is further compounded by the fact that the presence of the sodium mineral oil changes the physical state of the registered substance from solid to liquid and will therefore have a considerable effect on the result of any test conducted on the substance in solvent. It is therefore considered justifiable to omit any study, but the results from QSAR are included to allow for a weight of evidence approach.
Key value for chemical safety assessment
- Vapour pressure:
- 0 kPa
- at the temperature of:
- 25 °C
Additional information
The alkaryl benzene sulfonates are a group of inter-related substances of similar structure and chemical properties. Furthermore, the alkaryl benzene sulfonates have previously been assessed as a category approach under the Right to Know Initiative for HPV chemicals reviewed by the US EPA. It is therefore considered justifiable to undertake a similar approach to meet the requirements for REACH by reading across data between structurally related compounds.
As discussed above, it is not technically feasible to conduct a study to measure the vapour pressure of the substance and so estimations have been undertaken using the EPIWIN Modeling Program. To allow for a weight of evidence approach estimations have been made for all suitable molecular variations in the series benzene sulfonic acids and salts. The result given above is an average vapour pressure value calculated by QSAR across the series of substances, which is 8.96x10-15 kPa but is displayed as 0.000000001 because this is the smallest number that IUCLID 5 will support.
To further support this approach a QSAR Prediction Reporting Format (QPRF) is attached to justify the QSAR system as adequate for estimating the value for the purposes of REACH registration
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.
