Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 2014-05-27 to 2014-06-13
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Internationally accepted guideline was followed, all parameters are described in depth and in accordance with guideline. RSS is categorised with reliability 2 because it wasn't conducted under GLP conditions
Qualifier:
equivalent or similar to guideline
Guideline:
other: OECD 115
Deviations:
no
GLP compliance:
no
Type of method:
other: Critical Micelle Concentration Determination
Water solubility:
ca. 16 mg/L
Temp.:
20 °C
Remarks on result:
other: Result based on the Critical Micelle Concentration

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The Critical Micelle Concentration is therefore determined as 16 mg/L at 20°C
Executive summary:

Based on the surfacte tension determination at several concentrations, the Critical Micelle Concentration has been determined as 16 mg/L at 20°C
