Warning
H315 P302+P352
P332+P313
P362+P364
P264
P280
P321
It was highly irritating in a test by 24-hour occlusive application to the rabbit skin (IUCLID (2000)). Furthermore, it is described that this substance is one of the strongest primary skin irritants known (Contact Dermatitis (Frosch) (5th, 2011), corresponding to List 1), and it causes contact dermatitis in humans, and signs such as itchiness, vesicular papules, and skin detachment were observed (Environmental Risk Assessment for Chemical Substances vol. 3 (Ministry of the Environment, 2004)). Therefore, it was classified in Category 2.
3 Serious eye damage/eye irritation Category 1


Danger
H318 P305+P351+P338
P280
P310
It was classified in Category 1 because it was highly irritating in a test by application to the rabbit eye (IUCLID (2000)), and it is described that it is a severe human eye irritant (HSDB (2003)).
4 Respiratory sensitization Classification not possible
-
-
- - In an in vivo immunological test with guinea pigs, inhalation challenge did not induce respiratory allergy, the animals developed only low titer homocytotropic antibodies, and in a subsequent study, this substance was used as the negative control, and higher titer specific antibodies were not induced in the treated animals. Furthermore, this substance was negative in a mouse IgE test, therefore, it was concluded that the evidence indicates that the substance is not a respiratory allergen (ECETOC TR 77 (1999)). However, because there is no animal model for respiratory hypersensitivity testing at this point, it was classified as "Classification not possible" according to the GHS classification guidance for the Japanese government.
4 Skin sensitization Category 1


Warning
H317 P302+P352
P333+P313
P362+P364
P261
P272
P280
P321
P501
There are positive results in all of a maximization test and a Buehler test with guinea pigs and a mouse local lymph node test (ECETOC TR 77 (1999)), this substance is generally used as the positive control in a skin sensitization test (EHC 149 (1993), JECFA 855 (1996), JMPR 930 (1997)), and there are many reports indicating skin sensitization in occupational exposure of humans or tests by application to humans (Environmental Risk Assessment for Chemical Substances vol. 3 (Ministry of the Environment, 2004), ECETOC TR 77 (1999), DFGMAK-Doc.13 (1999)). Furthermore, it is listed as an allergen in Contact Dermatitis (Frosch) (Contact Dermatitis (5th, 2011)). Based on the above knowledge, it was classified in Category 1.
5 Germ cell mutagenicity Category 2


Warning
H341 P308+P313
P201
P202
P280
P405
P501
As for in vivo tests, a dose-dependent increase in DNA damage and a positive result were shown in an alkaline elution test by intraperitoneal administration to mice (in vivo genotoxicity test) (IUCLID (2000)), and as for in vitro tests, there are reports on a highly positive result in an Ames test (Mutagenicity Test Data of Existing Chemical Substances based on the toxicity investigation system of the Industrial Safety and Health Law (Supplement 3) (2005)), and positive results in a chromosomal aberration test with V79 cells and an HGPRT test (IUCLID (2000)). Therefore, based on expert judgment, it was classified in Category 2. And this substance is an existing chemical substance for which mutagenicity was confirmed under Article 57-3 of the Industrial Safety and Health Law. Besides, it is described that an in-vivo dominant lethal test was negative (DFGMAK-Doc.21 (2005)), but the test details are unknown.
6 Carcinogenicity Classification not possible
-
-
- - In carcinogenicity tests by 2-year diet administration to rats and mice (doses 320, 800, 2,000 ppm), in rats, increased incidences of renal cell adenoma in males and adenocarcinoma in the mammary gland in females were observed, but no increase in tumors was seen in male and female mice, and no carcinogenicity of this substance was shown for male and female mice (Results from Carcinogenicity Studies (Ministry of Health, Labour and Welfare, 1992)). Furthermore, it is reported that in tests by 18-month diet administration (250-2,000 ppm) to male rats and male and female mice, there was no increase in incidences of tumors in either species compared to the control groups (IUCLID (2000)). Because it was impossible to conclude the carcinogenicity of this substance from the above results, it was classified as "Classification not possible."
7 Reproductive toxicity Classification not possible
-
-
- - In a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test by oral administration to rats (OECD TG 422, GLP), lesions in the stomach (squamous epithelial hyperplasia, inflammatory cellular infiltration in the forestomach, etc.) were observed in males and females at 30 mg/kg as major general toxicological changes, but as for reproductive and developmental effects, no treatment-related changes were found in general status, and sexual function/fertility indexes such as those for copulation, fertility, gestation, and delivery in parent animals, or external appearance, general status, and developmental indexes such as live birth index, sex ratio, and viability index on day 4 in offspring (Safety Test (Ministry of Economy, Trade and Industry (METI)) (Access on Apr. 2012), corresponding to List 2). Therefore, no adverse effects on sexual function/fertility were seen, but on the other hand, it is reported that in a test by inhalation exposure to rats to a concentration of 0.13 mg/m3 during a gestation period, increased post-implantation resorptions were observed, and because it is described that there is no report on setting the control group (Environmental Risk Assessment for Chemical Substances vol. 3 (Ministry of the Environment, 2004)), and the details are unknown, the results were not used for classification. Due to insufficient data on effects on the development of offspring, it was classified as "Classification not possible."

As effects in humans, it is described that acute toxic signs such as blue lips, nail, and skin, dizziness, headache, and labored breathing occurred after inhalation or oral exposure, and it may cause effects on the blood and methemoglobin formation (Environmental Risk Assessment for Chemical Substances vol. 3 (Ministry of the Environment, 2004)). In animal tests, it is reported that methemoglobin formation was observed after oral administration of 640 mg/kg to rats, its level was 20% after 30 minutes, 17% after one hour, and 12% after two hours, and Heinz bodies were found only after 24 hours (IUCLID (2000)). Although the test dose in rats was within the guidance value range for Category 2, based on information in humans, it was classified in Category 1 (blood system). And it was classified in Category 3 (respiratory tract irritation) because it is described that exposure to this substance is irritating to the eye, respiratory tract, and skin in humans (Environmental Risk Assessment for Chemical Substances vol. 3 (Ministry of the Environment, 2004)). Besides, neurological symptoms such as headache, labored breathing, nausea, and vomiting occurred in humans after exposure to this substance, but they were not used for the rationale for classification due to unknown details.
9 Specific target organ toxicity - Repeated exposure Category 2 (nervous system, haemal system)


Warning
H373 P260
P314
P501
Chronic poisoning from this substance in humans causes a gradual onset of symptoms of retrobulbar neuritis with a blurring of vision, central scotoma, and constriction of visual fields, and optic neuritis also occurs, in exceptional instances leading to optic atrophy or impaired papillary reaction in accommodation, and retrobulbar neuritis from chronic poisoning is associated with peripheral neuritis, which causes paresthesias in the legs and burning of the feet (HSDB (2003)). Based on the above knowledge in humans (List 2), it was classified in Category 2 (nervous system). On the other hand, it is reported that in a test by 4-month inhalation exposure of rats (dust; 4 hours/day, 5 days/week) to a concentration of 1.1 mg/m3, after 2-week or 3-week exposure, abnormal behaviors, hyperemia in the visible mucous membrane, and dyspnea occurred, and 4/23 animals died, and after 4-month exposure, decreased hemoglobin level and erythrocyte counts, sulfhemoglobinemia were also observed (Environmental Risk Assessment for Chemical Substances vol. 3 (Ministry of the Environment, 2004)), although there is no description of setting the control group. Because the dose was within the guidance value range for Category 2, it was classified in Category 2 (blood system).
