Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
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
Qualifier:
no guideline followed
Principles of method if other than guideline:
The determination of the color and the physical state was performed by visual assessment.
The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.
GLP compliance:
no

liquid
Key result
Form:
liquid: viscous
Colour:
The sample of test item was visually assessed at 20.0 ± 0.5 ºC to be shiny dark brown.
Odour:
other: The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.
Substance type:
organic

Description of the Color:

The sample of test item was visually assessed at 20.0 ± 0.5 ºC to be shiny dark brown.

Description of the Physical State:

The sample of test item was visually assessed at 20.0 ± 0.5 ºC to be an opaque extremely viscous liquid.

Conclusions:
The color of the test item was visually assessed to be shiny dark brown at 20.0 ± 0.5 ºC.
The physical state of the test item was visually assessed to be an opaque extremely viscous liquid at 20.0 ± 0.5 ºC.
The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.
Executive summary:

Appearance. Shiny dark brown opaque extremely viscous liquid at 20.0 ± 0.5 °C by visual assessment. 

The odor was not determined as there was insufficient information to definitively confirm the test item did not present an inhalation hazard.
