Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
according to
Guideline:
other: OECD guideline 115
Version / remarks:
CMC measurement Du Noûy ring method
Principles of method if other than guideline:
The experiment was performed by mixing the substance with water in different ratio. The analyzed
substance all formed cloudy/hazy emulsions at every concentration tested; hence the solubility is very
low (below 0.1%). To more accurately be able to determine the low water solubility, CMC analysis was
employed.
GLP compliance:
no
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
other: Determination of CMC of surface active substance
Water solubility:
190 mg/L
Temp.:
20 °C
pH:
6
Conclusions:
The water solubiity of the substance is 190 mg/L
Executive summary:

The water solubility was determined as the Critical Micelle Concentration to be 190mg/L at pH 6 and 20 °C.

Description of key information

The substance has a water solubility of 190 mg/L. The Ctitical Micelle Concentration CMC is used as a measure of the solubility of the substance.

Key value for chemical safety assessment

Water solubility:
190 mg/L
at the temperature of:
20 °C
