Endpoint:
appearance / physical state / colour
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Study period:
From November 21, 2006 to February 19, 2007
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
KL2 due to RA
Justification for type of information:

solid
Key result
Form:
solid: crystalline
Remarks:
tenacious and sticky
Colour:
white
Odour:
other: faint, marzipan-like odour
Substance type:
organic

Due to the hygroscopic behaviour the substance deliquesced when it was bought to air for several minutes.

Conclusions:
Under the study conditions, the read across substance was a crystalline, hygroscopic, sticky white solid with a faint marzipan-like odour at 20ºC.
Executive summary:

A study was conducted to determine the appearance, physical state and colour of the read across substance according to EPA OPPTS 830.6302, .6303 and .6304, in compliance with GLP. Under the study conditions, the read across substance was a crystalline, hygroscopic, sticky white solid with a faint marzipan-like odour at 20ºC (Schulze, 2007).

Based on the results of the read across, a similar appearance/physical state is expected for the test substance.

Description of key information

The appearance, physical state and colour were determined based on a study conducted with read across substance, C12 -16 ADBAC according to EPA OPPTS 830.6302, .6303 and .6304 (Schulze, 2007)
