Water solubility

Link to relevant study record(s)

Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2009-10-19

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: The critical micelle concentration (CMC), was determined according to standardized method but without GLP compliance.

Qualifier:

according to guideline

Guideline:

other: OECD Guideline 115 (Surface Tension of Aqueous Solutions)

Deviations:

no

Principles of method if other than guideline:

According to "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", the critical micelle concentration (CMC) can be view as the solubility limit.

GLP compliance:

no

Type of method:

other: The cmc has been determined according to the harmonized ring method

Water solubility:

790 mg/L

Temp.:

23 °C

pH:

7

Details on results:

Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 790 mg/L (pH 7, 23°C).

Conclusions:

Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
Since the substance forms micelles in water, the water solubility is expressed as the critical micelle concentration (CMC), in this case 790 mg/L (pH 7, 23°C).
