Reference

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

April 15 to May 07, 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. QA statement)

Remarks:

inspected on 29 and 30 November 2010 / signed on 11 April 2011

Physical state at 20°C and 1013 hPa:

liquid

Key result

Form:

other: sticky paste like

Remarks:

"sticky paste like" as reported as observation during the preliminary test related to the determination of melting point of the substance and "pasty, orange brown to red" as reported in the description of the test item

Colour:

orange-brown to red-brown

Odour:

other: amber

Substance type:

organic

Conclusions:

The substance is orange-brown to red-brown sticky paste 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 of the substance. Observations recorded during the pre-test related to the determination of the melting point of the substance were also reported as additional information.

Description of key information

Orange-brown to red-brown sticky paste at room temperature and atmospheric pressure.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

liquid

Additional information

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

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 (-1.3 °C to 13.2 °C) (see endpoint 4.2, Laus, 2014), which is in accordance with the physical state considered at 20°C and 1013 hPa. Moreover, 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 55°C.
