1,3-diethyl-2,4-diisocyanato-5-methylbenzene

Particle size distribution (Granulometry)

Administrative data

Endpoint:

particle size distribution (granulometry)

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is marketed or used in a non solid or granular form

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Remarks:

physical state

Reference

Endpoint:

appearance / physical state / colour

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2017-06-06

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

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

Qualifier:

no guideline followed

Principles of method if other than guideline:

Visual description of the colour (in daylight by an observer with normal colour vision) and the physical state (at 20 °C and 1013 hPa)

GLP compliance:

no

Physical state at 20°C and 1013 hPa:

liquid

Key result

Form:

liquid

Colour:

light yellow

Odour:

other: not determined out of health and safety reasons

Substance type:

organic

Conclusions:

The determination of the test item's appearance / physical state / colour was determined scientifically reasonably by visual and sensorical inspection. There is no indication given that the results are not reliable.
• Physical state (at 20 °C and 1013 hPa): liquid
• Colour: light yellow

Executive summary:

The visual description of the colour and the physical state (at 20°C and 1013 hPa) resulted in the following: test substance is a light yellow liquid at 20°C and 1013 hPa.
