Endpoint:
appearance / physical state / colour
Type of information:
other: Observation documented in literature
Adequacy of study:
weight of evidence
Study period:
2008
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
secondary literature
Reason / purpose:
reference to same study
Qualifier:
no guideline required
Principles of method if other than guideline:
Visual observation of physical state and appearance as published in the literature.
GLP compliance:
not specified
Physical state at 20°C and 1013 hPa:
solid
Form:
liquid
Colour:
white to straw coloured
Substance type:
organic
Conclusions:
The physical state and appearance of the test item is described in existing literature. The test item was determined to be a white to straw-coloured crystalline solid. Applicant assessment indicates that this description is consistent with the visual observation performed on the test item.
Executive summary:

The appearance of the test item has been determined as:

Form: solid (bulk)

Colour: white to straw-coloured.

1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Visual observation of physical state and appearance by the testing laboratory
Reason / purpose:
reference to same study
Qualifier:
no guideline required
Principles of method if other than guideline:
Visual observation of physical state and appearance by the testing laboratory
GLP compliance:
yes
Physical state at 20°C and 1013 hPa:

Conclusions:
The physical state and appearance of the test item was evaluated by visual observation. The test item was determined to be colourless to beige blocks.
Executive summary:

The appearance of the test item has been determined as:

Form: solid (bulk)

Colour: colourless to beige
