Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2021
- 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:
- The description of the substance comes from study reports on other physico-chemical endpoints determined in accordance with internationally-recognized standard guidelines. In these reports, the substance is adequately defined and a certificate of analysis is available.
- Reason / purpose for cross-reference:
- reference to same study
- Remarks:
- Other physico-chemical endpoints are covered in the study report of Demangel (2021).

- Qualifier:
- no guideline required
- Principles of method if other than guideline:
- Visual inspection.
- GLP compliance:
- yes
- Remarks:
- The test substance is described in the context of GLP-compliant physico-chemical studies in the study report of Demangel (2021). The description is confirmed in the study report of Mathiak (2021) which concerns a non-GLP compliant physico-chemical study.
- Physical state at 20°C and 1013 hPa:
- solid
- Key result
- Form:
- solid: particulate/powder
- Colour:
- White to beige
- Substance type:
- inorganic
- Conclusions:
- Cerium gadolinium oxide is an inorganic solid appearing under the form of a white to beige powder.
- Executive summary:
The test substance was described as a white powder in the context of GLP-compliant physico-chemical studies (Demangel, 2021). A similar description as a white to beige powder was reported in the study report of Mathiak (2021) which concerns a non-GLP compliant physico-chemical study.
