HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity （Oral） Category 3 Danger H301: Toxic if swallowed P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P321: Specific treatment （see ... on this label）.
P330: Rinse mouth.
P405: Store locked up.
P501: Dispose of contents/container to ... 		Based on its rat LD50 = 98 mg/kg bw (IARC vol. 16 (1978)), the substance was classified into Category 3.
1 Acute toxicity （Dermal） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Solid (room temperature) (HSDB (2002))
1 Acute toxicity （Inhalation: Vapours） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Dusts and mists） Classification not possible - - - - No data available.
2 Skin corrosion/irritation Not classified - - - - Based on a result of a test using rabbits that the substance was mildly irritant (HSDB (2002)), it was classified into "Not classified".
3 Serious eye damage/eye irritation Category 2B - Warning H320: Causes eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling. 		Since it is reported that in a test using rabbits, the substance caused mild conjunctival reaction (HSDB (2002)), it was classified into Category 2B.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Classification not possible - - - - It is rated R43 (equivalent to Category 1) (EU-Annex I (accessed in August 2008)). However, due to a lack of data, classification is not possible.
5 Germ cell mutagenicity Classification not possible - - - - There is no in vivo test data available, and in vitro mutagenicity tests (Ames test, chromasomal aberration test, sister chromatid exchange test) showed positive results, but they were not so strong (NTP Database (accessed in August 2008)). Therefore, the substance was classified into "Classification not possible".
6 Carcinogenicity Classification not possible - - - - Carcinogenicity tests for two years indicated, in male rats, a significant incidence of interstitial-cell tumors of the testes, and in female mice, more incidences of alveolar/bronchiolar adenomas and alveolar/bronchiolar carcinomas than those of the historical control. However, in both tests, it was concluded that there was no convincing evidence of the carcinogenicity of the substance (NTP (TR126, 1978)). Therefore, the substance was classified into "Classification not possible".
7 Reproductive toxicity Classification not possible - - - - Teratogenicity was not noted in a rat percutaneous administration test during pregnancy (IARC vol. 16 (1978)) or in a mouse subcutaneous injection test (Teratogenic (12th, 2008)). However, neither test provided any information on parental fertility. Therefore, the substance was classified into "Classification not possible".
8 Specific target organ toxicity - Single exposure Classification not possible - - - - It is documented that in a percutaneous administration test using rats (doses, 4 - 32 mg/kg bw), no significant increase in methemoglobin levels (IARC vol. 16 (1978)). However, the test did not provide any detailed data on the test and other test information. Therefore, the substance was classified into "Classification not possible".
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - A carcinogenicity test using rats and mice (NTP (TR126, 1978)) showed only pathological findings on tumors sufficiently. A percutaneous administration test using rats for two years did not show any signs of toxic effects. However, hair dyes containing different ingredients were used as test substances: 4% 2,5-diaminotoluene sulfate or 3% 2,5-diaminotoluene and 0.75% 2,4-diaminoanisole sulfates (IARC vol. 16 (1978)). Due to the inconsistency in test substance used, the substance was classified into the "Classification not possible" category.
10 Aspiration hazard Classification not possible - - - - No data available.
