- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: ISO Standard 304-1985, plate method
- Deviations:
- no
- Principles of method if other than guideline:
- The surfaee tension of a solution of surfaetant generally deereases with inereasing eoneentration until the CMC is aehieved. At higher eoneentration, the surfaee tension remains essentially unehanged. In agraph of the surfaee tension as afunetion of eoneentration, points form normally two straight lines with different slopes. The CMC is given by the interseetion of the two straight lines.

- Conclusions:
- CMC (water solubility) at 20°C in water: 0.025 ± 0.002 g/L
- Executive summary:
The water solubility of Octadecanoic acid, reaction products with diethylenetriamine, di-Me sulfate-quaternized was determined using the critical micelle concentration accordign to ISO 304 -1985 (plate method). According to the Guidance on information requirements and chemical safety assessment, chapter R.7a, since the substance was established to be a surfactant, it is prudent to take the critical micelle concentration (CMC) as a solubility limit.
The CMC (water solubility) at 20°C was determind to be 0.025 ±0.002 g/L, pH at 20°C: 6.0.

Applicant's summary and conclusion
- Conclusions:
- CMC (water Solubility) at 20°C (pH = 6.0): 0.025 ± 0.002 g/L
n-octanol Solubility at 20°C: 0.396± 0.008 g/L
Partition Coefficient: log Pow = 1.20 - Executive summary:
The n-octanol/water partition coefficient of Octadecanoic acid, reaction products with diethylenetriamine, di-Me sulfate-quaternized was determined by measuring teh individual solubilities in n-octanol and water. The solubility of the test item in n-octanol was determined to be 0.396 ± 0.008 g/L. The CMC (water Solubility) was determined to be 0.025 ± 0.002 g/L at 20 °C. Thus, the log Kow is calculated as 1.20.
