Reference

Reference 1

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

25 - 28 September 2017

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 13 and 14 October 2014 / signed on 08 April 2015

Physical state at 20°C and 1013 hPa:

solid

Key result

Form:

other: high viscous sticky paste

Remarks:

(as reported in the description of the substance). Note that during the relative density determination (see endpoint 4.4, Laus,2017), a homogeneous molten mass of the test item without bubble was obtained at approximately 80°C.

Colour:

dark green

Substance type:

organic

Conclusions:

The substance is a dark green high viscous 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.

Description of key information

The test substance is a dark green to brown high viscous sticky paste at ambient temperature and atmospheric pressure.

It is considered as a solid.

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 GLP reports on physico-chemical properties of the substance.

They are considered as key studies. The results are retained as key data.

Note that during the relative density determination (see endpoint 4.4, Laus,2017), a homogeneous molten mass of the test item without bubble was obtained at approximately 80°C.
