water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
August 2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Well conducted study, based on OECD guideline 105, certificate of analysis included in the report.
Qualifier:
equivalent or similar to
Guideline:
OECD Guideline 105 (Water Solubility)
Deviations:
yes
Remarks:
A limit test was performed: only at one time period after adding the test substance the concentration of the test substance was analyzed.
Principles of method if other than guideline:
A limit test was performed: only at one time period after adding the test substance the concentration of the test substance was analyzed.
GLP compliance:
no
Type of method:
flask method
Water solubility:
< 1 µg/L
Temp.:
20 °C
Remarks on result:
other: pH not noted

The final result for water solubility of the test substance, as determined at time point 2 hours after adding the test substance, was calculated to be lower than 1 µg/L.  

The results of determined concentration of test substance are presented in the table below.

Conclusions:
Interpretation of results (migrated information): insoluble (< 0.1 mg/L)
The water solubility at 20°C of dihexadecyl peroxodicarbonate is lower than 1 µg/L, the detection limit.
Executive summary:

The water solubility of dihexadecyl peroxodicarbonatewas determined in a limit test set at a temperature of 20°C and based on OECD guideline 105. The data on water solubility represent the saturation mass concentration of the test substance in water.

The determined final result for water solubility of the test substance was calculated to be lower than 1 µg/L, the detection limit.

Description of key information

The water solubility at 20°C of dihexadecyl peroxodicarbonate is lower than 1 µg/L, the detection limit.

Key value for chemical safety assessment
