Rationale for the classification
1 Acute toxicity (Oral) Not classified
-
-
- - It was classified as "Not classified" based on a report on an LD50 value of > 5,000 mg/kg for rats (Safety Data for Pharmaceutical Excipients, Japan Pharmaceutical Excipients Council (Access on October 2013)). The category was revised based on the information obtained in this investigation.
1 Acute toxicity (Dermal) Not classified
-
-
- - Classification not possible due to lack of data. Besides, it was classified as "Not classified" based on a report on an LD50 value of > 5,000 mg/kg for rabbits (Safety Data for Pharmaceutical Excipients, Japan Pharmaceutical Excipients Council (Access on October 2013)). The category was revised based on the information obtained in this investigation.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible
-
-
- - Classification not possible due to lack of data.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - Classification not possible due to lack of data.
2 Skin corrosion/irritation Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, it is reported that moderate irritation was found in a 24-hour irritation test with rabbits, and as a result of 48-hour occlusive patch application of a 2% concentration of this substance in liquid paraffin to human subjects, no irritation was observed (Safety Data for Pharmaceutical Excipients, Japan Pharmaceutical Excipients Council (Access on October 2013)).
3 Serious eye damage/eye irritation Classification not possible
-
-
- - Classification not possible due to lack of data.
4 Respiratory sensitization Classification not possible
-
-
- - Classification not possible due to lack of data.
4 Skin sensitization Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, it is reported that no sensitization was observed in a maximization test in 30 human subjects with a 2% concentration of this substance in liquid paraffin (Safety Data for Pharmaceutical Excipients, Japan Pharmaceutical Excipients Council (Access on October 2013)).
5 Germ cell mutagenicity Classification not possible
-
-
- - Classification not possible due to lack of data. As for in vitro, it is reported that it was negative in a bacterial reverse mutation test (Safety Data for Pharmaceutical Excipients, Japan Pharmaceutical Excipients Council (Access on October 2013)).
6 Carcinogenicity Classification not possible
-
-
- - Classification not possible due to lack of data.
7 Reproductive toxicity Classification not possible
-
-
- - Classification not possible due to lack of data.
8 Specific target organ toxicity - Single exposure Classification not possible
-
-
- - Classification not possible due to lack of data.
9 Specific target organ toxicity - Repeated exposure Classification not possible
-
-
- - Classification not possible due to lack of data.
10 Aspiration hazard Classification not possible
-
-
- - Classification not possible due to lack of data.
