Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental Dates : 12-13. Feb. 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Remarks:
Data comes from the description of the test substance in the report on other physico-chemical property. No guideline is required according to REACh TGD. The test substance is adequately characterised. Therefore full validation applies.
Reason / purpose:
reference to same study
Qualifier:
no guideline required
Principles of method if other than guideline:
Visual observation.
GLP compliance:
yes (incl. certificate)
Remarks:
Landesamt für Umwelt (inspected on 15-16/11/ 2017, signed on 15/05/2018)
Specific details on test material used for the study:
Storage conditions: closed original container (metal bottle) under inert gas at 4 – 9 °C
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid
Remarks:
wax-like
Colour:
pale brown

The observation was confirmed with the melting point measurement (same report) where it was proven by the DSC that the substance was a true solid, and not a very viscous liquid.

Executive summary:

The test substance was tested under GLP for other physico-chemical property.

In the report, the sample is described as a pale brown, wax-like, solid. The physical state was conformed with the melting point measurement.

Description of key information

Pale brown, wax-like, solid.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

Experimental studies were conducted under GLP for the determination of physicochemical properties of the substance; the report on melting point was selected, including fully reliable description of the test sample, and confirmation of physical test as true solid, from melting transition. The result is retained as key value.
