The substance was classified as Category 1based on the report that the substance was strong skin sensitizer (HSDB (2003)) and on the report in which the substance was considered as a sensitizer (Contact Dermatitis, Frosch, 4th, (2006)).
5 Germ cell mutagenicity Classification not possible - - - - The classification was not possible due to lack of in vivo test data. As relevant information, negative results in the Ames test were reported (IARC 79 (2001), NTP DB (Access on Oct. 2010)).
6 Carcinogenicity Classification not possible - - - - The classification was concluded as "Classification not possible" based on the criterion of "Group 3" in the carcinogenicity assessment by the IARC (IARC 79 (2001)).
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - Classified as "Not classified" from its 48h-LC50 = 193 mg/L for crustacea (Daphnia magna) (AQUIRE, 2012).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Classified as "Not classified" since all reliable chronic toxicity data are LOEC >= 1mg/L (AQUIRE, 2012) though adequate data on rapid degradation are not available.
12 Hazardous to the ozone layer Classification not possible - - - - This substance is not listed in Annexes to the Montreal Protocol.
