Water solubility

Link to relevant study record(s)

Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

May 9th, 2016

Reliability:

1 (reliable without restriction)

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

Principles of method if other than guideline:

The method has been conducted in reverse - i.e. rather than add test material to water until saturation, water has been added to test material. This is due to the unique nature of the test material, as at high enough concentrations it behaves as a gel rather than a solution.

GLP compliance:

no

Type of method:

flask method

Water solubility:

490 g/L

Temp.:

25 °C

pH:

>= 5 - <= 7

Remarks on result:

other: pH is based on the pH of the substance itself, as reported in the available safety data sheet. The pH is not reported in the study report

Conclusions:

Interpretation of results (migrated information): very soluble (> 10000 mg/L)
The water solubility is determined to be approximately 49% at 25°C. Above this concentration the solution behaves like a gel at 25°C.

Executive summary:

The study has been conducted to a method equivalent to the OECD 109 flask method, however the process has been reversed and instead of adding test material to water until saturation, water is added to test material until a gel-like phase is reached. Due to the unique nature of the test material, it forms a gel-like solution at high enough concentrations, and as such the standard flask method is not appropriate. The result is a water solubility of 49% at 25°C, equivalent to 490 g/l, or 490000 mg/l.

Description of key information

The water solubility is determined to be approximately 49% at 25°C. Above this concentration the solution behaves like a gel at 25°C.

Key value for chemical safety assessment
