Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

14/11/1995

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Remarks:

Data comes from the description of the test substance in the report on other physicochemical property. No guideline is required. The substance identification is not complete (composition missing). Therefore validation applies with restrictions.

Qualifier:

no guideline required

Principles of method if other than guideline:

Visual observation.

GLP compliance:

no

Specific details on test material used for the study:

Test substance identification is equivocal: the substance is a reaction mass of 7-methyl (major) and 6-methyl (minor) isomers, but the structural formula drawn in the report corresponds to the minor isomer. Moreover, substance composition is not specified.

Physical state at 20°C and 1013 hPa:

Executive summary:

The test substance was studied for other physico-chemical property. In the report, the sample is described as a colourless liquid.

Description of key information

Colourless liquid.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

liquid

Additional information

An experimental study was conducted for the determination of other physicochemical property of the substance, including description of the test sample. Despite restrictions due to incomplete identification, the result is considered reliable, and retained as key value.
