Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
15 April -15 May 2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Justification for type of information:
Data come from the description of the test substance in the GLP report on another physico-chemical property. No guideline is required according to REACh TGD. The substance is considered to be adequately characterised. Therefore full validation applies.
Qualifier:
no guideline required
Principles of method if other than guideline:
Visual observation
GLP compliance:
yes (incl. certificate)
Remarks:
inspected on 29 and 30 November 2010 / signed on 11 April 2011
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid

at room temperature (as reported in the report and in the Certificate of analysis of the supplier)
Colour:
dark brown
Odour:
other: "powerful, amber" according to the Certificate of analysis provided by the supplier
Substance type:
organic
Conclusions:
The substance is a dark brown solid at room temperature and atmostpheric pressure
Executive summary:

Data come from the description of the test substance reported in the GLP study report on physico-chemical property on the substance and in the certificate of analysis provided by the supplier of the substance.

Description of key information

Dark brown pasty mass to solid at room temperature and atmospheric pressure

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
solid

Additional information

Data come from the description of the test substance in the GLP reports on physico-chemical properties of the substance.

They are considered as key studies. The result is retained as key data.

Note that the melting range of the substance was determined to be between 16.4 °C and 36.8 °C (see endpoint 4.2, Laus, 2014), which is in accordance with the physical state considered at 20°C and 1013 hPa.

In addition, during the determination of the melting range of the substance, it was observed that the test item became sticky when the substance melts. Finally, according to flowability test performed during the relative density determination (see endpoint 4.4, Laus,2014), it was observed that the test item was flowable at 65 - 70°C.
