Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
supporting study
Study period:
2014
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Remarks:
Data comes from the description of the test substance in the report on granulometry. No guideline is required according to REACh TGD. Purity is specified. Therefore full validation applies.

no guideline required
Principles of method if other than guideline:
binocular (stereo) microscope examination
GLP compliance:
no
Physical state at 20°C and 1013 hPa:
solid
Form:
crystalline
Colour:
White

Adequacy of study:
key study
Study period:
From November 20 to December 07, 2007
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Remarks:
Data comes from the description of the test substance in the report on other physico-chemical properties. No guideline is required according to REACh TGD. The substance is considered to be adequately characterised with its purity. Therefore full validation applies.
