Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

08 - 19 December 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 observations and melting point value obtained in the GLP Melting point study (see endpont 4.2) conducted on the registered substance. 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 and melting point determination (see endpoint 4.2)

GLP compliance:

yes (incl. QA statement)

Remarks:

inspected on 15 and 16 November 2017 / signed on 15 May 2018

Physical state at 20°C and 1013 hPa:

liquid

Remarks:

very hard sticky paste not flowable, like a resin but not solid

Key result

Form:

liquid: viscous

Remarks:

very hard sticky paste not flowable, like a resin but not solid

Colour:

brown

Substance type:

organic

At room temperature, the test item was not flowable very hard sticky paste like a resin but not solid. At 5.1°, the test item was hard and difficult to pierce. At -22.9°C and -80°C, the test item was solid like ice.

Results obtained by DSC do not allow to determine the melting point of the substance without ambiguity. Finally, the melting point of the substance was considered as < 5.1°C based on pre-test results.

Conclusions:

The test substance is a not flowable very hard sticky paste, like a resin but not solid at ambient temperature and atmospheric pressure.

Executive summary:

The data come from the observations and melting point value obtained in the GLP Melting point study (see endpont 4.2) conducted on the registered substance.

Description of key information

The test substance is a brown to brown red paste also described as a not flowable very hard sticky paste like a resin but not solid at ambient temperature and atmospheric pressure

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

liquid

Additional information

The data come from the description of the test substance in the certificate of analysis of the supplier of the substance to be tested for physico-chemical properties and on the observations and melting point value obtained in the GLP Melting point study.
