- Endpoint:
- appearance / physical state / colour
- Type of information:
- other: visual observation
- Adequacy of study:
- key study
- Study period:
- November 1st, 2007 - July 09th, 2008
- Reliability:

- Specific details on test material used for the study:
- - Analytical purity: 82.3%
- Purity test date: Not available
- Lot/batch No.: GN-8
- Expiration date of the lot/batch: Not available
- Appearance: Amber coloured, extremely viscous liquid
- Storage: In the dark at room temperature
- Additional information on test material used for the study: It was attempted to purify the substance to a purity of >80% by using an alternative synthetic route, as opposed to the usual commercial route of synthesis which results in a purity of the substance of approximately 40% in water. This alternative synthetic route generated the substance at 82.3% purity, however it also generated an impurity (methanol at 4.0%) which is not present in the commercial substance. Based on the classification and labelling of methanol, it is considered that this additional impurity would not have an influence on any of the endpoints discussed in this dossier other than the acute oral toxicity study. Therefore all studies (including the one covering this endpoint) contained in this dossier (other than the acute oral toxicity study) were conducted on the 82.3% pure substance containing the 4.0% methanol impurity. The acute oral toxicity study has been conducted on the commercially generated substance at a purity of approximately 40% in water. - Physical state at 20°C and 1013 hPa:

- Conclusions:
- The test material is an amber coloured, extremely viscous liquid under normal conditions of temperature and pressure.
- Executive summary:
The test material is an amber coloured, extremely viscous liquid under normal conditions of temperature and pressure.
