Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Reason / purpose for cross-reference:
reference to other study
Qualifier:
according to guideline
Guideline:
other: ASTM D1331
GLP compliance:
no
Type of method:
other: derived from surface tension
Key result
Water solubility:
72 mg/L
Conc. based on:
act. ingr. (total fraction)
Temp.:
21 °C
Remarks on result:
other: For surfactants, the Critical Micell Concentration (CMC) is used as solubility. The CMC is derived from the measurement of the surface tension.
Conclusions:
The CMC of the test material was determined to be 72 mg/L; The CMC is used to describe the water solubility of surface active substances.
Executive summary:

The CMC of the test material was determined to be 72 mg/L from plotting the surface tension measured with a tensiometer against concentration; The CMC is used to describe the water solubility of surface active substances.

Description of key information

The solubility of the test item Sophorolipids: fermentation products of glucose and fatty acids, C18 (unsaturated), glycerol esters with yeast Starmerella bombicola, hydrolysed is best described with its Critical Micell Concentration (CMC) as the substance is surface active.

Key value for chemical safety assessment

Water solubility:
72 mg/L
at the temperature of:
21 °C
