Appearance / physical state / colour
Administrative data
- Endpoint:
- appearance / physical state / colour
- Type of information:
- other: based on experience
- Adequacy of study:
- weight of evidence
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: based on observation
- Justification for type of information:
- No guideline is required according to REACh TGD. Considering that the substance is well characterised and that the data come from a GLP study, full reliability applies.
