Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- other: OECD Guideline 105
- Version / remarks:
- According to ECHA “Guidance on Information Requirements and Chemical Safety Assessment - Chapter R.7a: Endpoint specific guidance” (version 6.0, 2017), table “Table R.7.1-6 Methods for determination of partition coefficient n-octanol/water”, there is no current guideline to measure the solubility in octanol. A test method can be based on the principled of OECD Guideline 105.

Calibration
The calibration of the analytical method resulted in the following calibration curve:
R-Square: 99.8813%
Offset: -0.1313
Slope: 0.1038
Curve: 0.0006
Study results
The concentrations of the different test solutions were calculated automatically using the equation of the calibration curve. The results are summarised in the table below:

n-Octanol solubility of the test item Sodium Hydroxymethanesulphonate is < 20 mg/L.
The n-octanol solubility was determined at 20 °C.
Applicant's summary and conclusion
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.
