---|---|---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Category 4 |
Warning |
H302 | P301+P312 P264 P270 P330 P501 |
Rat LD50 value = 680mg/kg (IUCLID (2000), HSDB (Access on Oct 2005)) and 779mg/kg (IUCLID(2000)). Based on the data above, it was classified as category 4. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Dermal) | Category 3 |
Danger |
H311 | P302+P352 P361+P364 P280 P312 P321 P405 P501 |
It was set as Category 3 based on rat LD50 value = 447mg/kg (IUCLID (2000), HSDB (Access on Oct 2005)). | FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Inhalation: Gases) | Not classified (Not applicable) |
- |
- | - | Solid (GHS definition) | FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible |
- |
- | - | No data available | FY2006 | GHS Classification Manual (10 Feb, 2006) |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | There is the data stating that rat LC50 (4 hours) value was >0.056mg/L (IUCLID (2000), HSDB (Access on Oct 2005)). But it was not able to judge whether it would correspond to Category of except for category 1 from this data. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
2 | Skin corrosion/irritation | Not classified |
- |
- | - | Although a potential of stimulating the skin slightly as effect of short-term exposure to humans is suggested (HSDB (Access on Oct 2005), HSFS (2004) and ICSC (J) (2000)), there is no case reports. On the other hand, there was description that irritation was not admitted by the test which used the rabbit (IUCLID (2000), HSDB (Access on Oct 2005)). So it was set as the outside of Category. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
3 | Serious eye damage/eye irritation | Category 2B |
Warning |
H320 | P305+P351+P338 P337+P313 P264 |
We classified it as Category 2B based on the descriptions that mild irritation was acknowledged in the tests using the rabbits (IUCLID (2000) and HSDB (Access on Oct 2005)). | FY2006 | GHS Classification Manual (10 Feb, 2006) |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | No data | FY2006 | GHS Classification Manual (10 Feb, 2006) |
4 | Skin sensitization | Classification not possible |
- |
- | - | Although the result was indicated as sensitizing in Maximization test which used the guinea pigs in IUCLID (2000), we presupposed that we could not categorize it according to the technical guidelines since the ratio of the animals in which sensitization was observed was not indicated. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
5 | Germ cell mutagenicity | Not classified |
- |
- | - | It was negative in the micronucleus test which used the mouse, which is an in vivo mutagenicity test using a somatic (IUCLID (2000)). So it carried out the outside of Category. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
6 | Carcinogenicity | Not classified |
- |
- | - | Since it was classified into 3 in IARC (Access on Oct 2005), it was considred as the outside of Category. [special notes] Although the carcinogenic of the product is not clear, beta-naphthylamine which is constitutional isomer of the product has carcinogenic for humans (it was classified into a group 1 in IARC. 2005). Therefore, it needs to be careful that the product may have beta-naphthylamine as impurities. |

7 | Reproductive toxicity | Classification not possible |
- |
- | - | No data available | FY2006 | GHS Classification Manual (10 Feb, 2006) |
8 | Specific target organ toxicity - Single exposure | Category 2 (blood) |
Warning |
H371 | P308+P311 P260 P264 P270 P405 P501 |
It was judged that the target organ of this substance was blood. Because there is a report in PATTY (4th, 1994) that methemoglobin is formed at the forced oral dosage of 200mg/kg in dogs, although there are no specific case reports in humans, there are reports of possible methemoglobinemia in the reference, Priority 2 (HSDB (Access on Oct 2005), ICSC (J) (2000), HSFS (2004), SITTIG (4th, 2002)). So the substance was classified as Category 2. | FY2006 | GHS Classification Manual (10 Feb, 2006) |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |

- | - | No data available | FY2006 | GHS Classification Manual (10 Feb, 2006) |
