Solubility in organic solvents / fat solubility

Link to relevant study record(s)

Reference

Endpoint:

solubility in organic solvents / fat solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

03/04-2013

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Principles of method if other than guideline:

The method corresponds to the Council Regulations EC No 440/2008, Guideline Part A – Methods for the Determination of the Physical-Chemical Properties, A.6, “Water solubility” (adopted, May 2008) and to the OECD Guidelines for Testing of Chemicals No: 105 “Water solubility“ (adopted 27th July 1995).

GLP compliance:

yes (incl. QA statement)

Medium:

n-octanol

Solubility:

< 2 mg/L

Temp.:

20 °C

Details on results:

A saturated solution (solution with residue of the test item) of the substance was observed after 24 hours. Therefore the 1-octanol solubility of Nigrosin WLF was set to < 2 mg/L.

Conclusions:

The determined n-octanol solubility of the substance was < 2 mg/L at 20°C.

Executive summary:

With a method corresponding to the OECD Guideline 105 (flask method) the n-octanol solubility was determined to be < 2 mg/L at 20 °C. A saturated solution of the substance was observed after 24 hours.

Description of key information

The determined n-octanol solubility of the substance was < 2 mg/L at 20°C.

Key value for chemical safety assessment

Solubility in organic solvents at 20°C:

2 mg/L

Additional information

With a method corresponding to the OECD Guideline 105 (flask method) the n-octanol solubility was determined to be < 2 mg/L at 20 °C. A saturated solution of the substance was observed after 24 hours.
