Reason / purpose for cross-reference:
data waiving: supporting information
Reference
Endpoint:
appearance / physical state / colour
Type of information:
other: Visual study
Adequacy of study:
key study
Study period:
15.08.2014

2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Visual studies' results have been recorded several times with same results.
Reason / purpose for cross-reference:
assessment report
Qualifier:
no guideline followed
Principles of method if other than guideline:
The appearance/physical state and colour of the substance have been determined in glass bottles in daylight as well as indoors in lamplight in ambient conditions when being manufactured, handled in other studies and when being used by downstream users.
