Specific details on test material used for the study:

Name: FAT 40549/A
Batch No: TV 1
Colour: Yellow-brown
Aggregate State at room temp: Solid
Stability in Solvent: in water: 48 hours
Stability at storage conditions: Stable
Molecular Weight. 1138 g/mol
Analysis: HPLC
Storage: at room temperature
Expiration Date: January 01, 2001

Water solubility:

> 385 g/L

Temp.:

21 °C

Remarks on result:

other: Further tests could not be carried out because the highly viscous solution could not be exactly measured (e.g. by pipetting).

Conclusions:

The solubility of test item was found to be greater than 385 g/L at 21 degree C, indicating that the substance is highly soluble in water.

Executive summary:

The water solubility of the test substance was determined according to EU method A.6 and OECD test guideline 105.

The method used was shake flask. 1g test substance FAT 40549/A was weighed into a glass-stoppered 5 ml graduated test tube and 2.0 mL distilled water was added at room temperature (21 degree C). The mixture was powerful shaken and the solubility was checked by visual judgement. In the dark red and highly viscous solution no undissolved particles are observed even if a strong light source is used..

Based on the findings of the study, the solubility of test item was found to be greater than 385 g/L at 21 degree C, indicating that the substance is highly soluble in water.

Description of key information

Water solubility: >= 385 g/L

Key value for chemical safety assessment
