- | - | Classification not possible due to lack of data. Besides, it is described in HSDB (Access on October 2013) that this substance is mildly irritating to the skin and has produced contact dermatitis. However, because it is unknown whether it corresponds to Category 3 in UN GHS ("Not classified" in JIS), it was classified as "Classification not possible". | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |

Warning |
H341 | P308+P313 P201 P202 P280 P405 P501 |
As for in vivo, among tests with mouse bone marrow cells, it was positive in a micronucleus test, equivocal in a chromosomal aberration test, and positive in a sister chromatid exchange test (NTP DB (Access on September 2013)). As for in vitro, it was positive in a bacterial reverse mutation test, a chromosomal aberration test and a mouse lymphoma test with cultured mammalian cells (NTP DB (Access on September 2013)). From the above, it was classified in Category 2. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
6 | Carcinogenicity | Category 1A |
Danger |
H350 | P308+P313 P201 P202 P280 P405 P501 |
This substance was classified in Category 1A because it is classified in Group 1 by IARC (IARC 100F (2012)), A1 by ACGIH (ACGIH (1987)), K by NTP (NTP RoC (1980)), and Carc. 1A in EU CLP (ESIS (Access on Sept 2013)). Besides, urinary tract tumors due to work involving exposure to beta-naphthylamine, a carcinogen, are included in Disease designated by the Minister of Health, Labour and Welfare under the Industrial Safety and Health Act in Japan, and its manufacture is prohibited. It is concluded in IARC 100F (2012) that there was sufficient evidence in humans for the carcinogenicity of this substance in the urinary bladder. It is reported that many cases of bladder cancer in workers exposed to this substance were found, and the cumulative incidence was 25%. Furthermore, as for the relationship between exposure of workers engaged in manufacturing and use of this substance and the risk of urinary bladder cancer, 11 cohort studies in the United States, the United Kingdom, Japan, Poland, Russia, and Italy are available, all of which showed that the risk of human bladder cancer was significantly increased. For example, 26 bladder-cancer deaths were observed in British dyestuff-industry workers exposed to this substance, with an expected value of 0.3 (Standardized Mortality Ratio (SMR) 86.7, 95% CI: 56.6-127.0), and 58 cases of bladder cancer were found in the British rubber industry workers from 1946 to 1949 when antioxidants containing this substance were used (Standardized Incident Ratio (SIR) 1.71; 95% CI: 1.3-2.21). | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |

11 | Hazardous to the aquatic environment Short term (Acute) | Category 1 |
Warning |
H400 | P273 P391 P501 |
From 72-hour ErC50 = 0.50 mg/L for algae (Pseudokirchneriella subcapitata) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2002)), it was classified in Category 1. | FY2013 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.0)) |
11 | Hazardous to the aquatic environment Long term (Chronic) | Category 1 |
Warning |
H410 | P273 P391 P501 |
If chronic toxicity data are used, then it is classified in Category 1 due to being not rapidly degradable (BIOWIN), and 21-day NOEC = 0.014 mg/L for crustacea (Daphnia magna) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2002)). If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 2 due to being not rapidly degradable (BIOWIN), and 96-hour LC50 = 3.9 mg/L for fish (Oryzias latipes) (Results of Aquatic Toxicity Tests of Chemicals conducted by Ministry of the Environment in Japan (Ministry of the Environment, 2002)). By drawing a comparison between the above results, it was classified in Category 1. |
