Endpoint:
appearance / physical state / colour
Type of information:
other: Expert judgment
Adequacy of study:
key study
Study period:
Testing was conducted between 15 June 2011 and 20 December 2011.
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
The physical state was determined by visual assessment, using a procedure designed to be compatible with Method 830.6303 of the OPPTS Guidelines, August 1996; the colour was determined by visual assessment and using the Munsell® Colour System, using procedures designed to be compatible with Method 830.6302 of the OPPTS Guidelines, August 1996. The work described was performed in compliance with UK GLP standards (Schedule 1, Good Laboratory Practice Regulations 1999 (SI 1999/3106 as amended by SI 2004/0994)). These Regulations are in accordance with GLP standards published as OECD Principles on Good Laboratory Practice (revised 1997, ENV/MC/CHEM(98)17); and are in accordance with, and implement, the requirements of Directives 2004/9/EC and 2004/10/EC.

Key result
Form:
powder
Colour:
A white powder containing a pale yellow crystalline solid (see overall remarks section for Munsell colour system results for the white powder and pale yellow crystalline solid).
Odour:
other: The odour was not determined, since the test item had not been fully tested and inhalation effects were unknown.
Substance type:
organic
Conclusions:
The test item has been determined to be a white powder containing a pale yellow crystalline solid (Munsell® Colour N9.5/90.0% R for the white powder and 5Y 9/4 for the pale yellow crystalline solid) at 22.0 ± 0.5°C.
Executive summary:

The physical state was determined by visual assessment, using a procedure designed to be compatible with Method 830.6303 of the OPPTS Guidelines, August 1996; the colour was determined by visual assessment and using the Munsell®Colour System, using procedures designed to be compatible with Method 830.6302 of the OPPTS Guidelines, August 1996. 

The odour was not determined, since the test item had not been fully tested and inhalation effects were unknown.

The test item was determined to be a white powder containing a pale yellow crystalline solid (Munsell® Colour N9.5/90.0% R for the white powder and 5Y 9/4 for the pale yellow crystalline solid) at 22.0 ± 0.5°C.
