P301+P312
P264 P270 P330 P501 |
[Rationale for the Classification] Data in (1)-(2) are reported as LD50 values for rats, and both correspond to Category 4. Therefore, it was classified in Category 4. [Evidence Data] (1) LD50 value for rats: 495 mg/kg (NICNAS IMAP (Accessed Jul. 2018)) (2) LD50 value for rats: 930 mg/kg (PATTY (6th, 2012)) |

[Rationale for the Classification] Based on data of LD50 values in (1)-(2) for rats or rabbits, it was classified in Category 3. [Evidence Data] (1) LD50 values for rats or rabbits: 500-1,000 mg/kg (SIAP (2013)) (2) LD50 value for rabbits: 925 mg/kg (NICNAS IMAP (Accessed Jul. 2018)) |

Warning |
H332 |
P304+P340
P261 P271 P312 |
[Rationale for the Classification] Based on (1) and (2), it was classified in Category 4. Besides, since the test was conducted at a higher concentration than the saturated vapor pressure concentration (0.46 mg/L) of this substance, it was handled as an inhalation study with mist. [Evidence Data] (1) LC50 value (4 hours) for rats : 4.4 mg/L (NICNAS IMAP (Accessed Jul. 2018), HSDB (2008)) (2) LC50 value (1 hour) for rats: >8.22 mg (converted 4-hour equivalent value: >2.06 mg) (HSDB (2008)) |

[Rationale for the Classification] Based on (1) and (2), it was classified in Category 1A. Besides, the category was changed from the previous classification by using new information sources. [Evidence Data] (1) In a GLP-compliant study in which rabbits were divided into 4 groups (n=3) and exposed to 0.5 mL of this substance by patch for one minute, necrosis with erythema was observed in one or more animals 1 hour after application in the group in which the skin was wiped with dry gauze, in the group in which the skin was washed with distilled water, and in the group in which the skin was swabbed with PEG 300 after washing with distilled water (NICNAS IMAP (Accessed Jul. 2018), REACH registration dossier (Accessed Sept. 2018), HSDB (2014)). (2) There is a report that in a Draize test with rabbits (n=3), erythema and edema were observed after a 3-minute application, and this did not resolve after 7 days (REACH registration dossier (Accessed Sept. 2018)). [Reference Data, etc.] (3) In a Draize test or a test similar to OECD TG404 with rabbits, aliphatic secondary amines are known to be corrosive to the skin (SIAP (2013)) |
3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 |
P305+P351+P338
P280 P310 |
[Rationale for the Classification] Based on (1)-(3), it was classified in Category 1. [Evidence Data] (1) It was classified in Category 1A for skin corrosion/irritation. (2) There is a report of severe corneal damage in an eye irritation test (OECD TG405) with rabbits (NICNAS IMAP (Accessed Jul. 2018)) (3) This substance is considered to cause strong eye irritation (PATTY (6th, 2012), HSDB (2014)). |
4 | Respiratory sensitization | Classification not possible |

- | - |
[Rationale for the Classification] Classification not possible due to lack of data. |
4 | Skin sensitization | Classification not possible |
- |
- | - |
[Rationale for the Classification] There are animal study data in (1) and (2), but they were judged inadequate to classify as "Not classified." Therefore, it was classified as "Classification not possible." [Evidence Data] (1) There is a report that no sensitization was induced, and necrosis was observed when this substance was applied to the ears of mice (NICNAS IMAP (Accessed Jul. 2018)). (2) There is a report that when a solution of this substance (plural preparations at 0.05-100%) was applied to the ears and abdomens of mice, reactions were shown in both the treated and control groups. Therefore, irritation and sensitization were indistinguishable (REACH registration dossier (Accessed Sept. 2018)). [Reference Data, etc.] (3) There is a description that this substance may be a sensitizer (PATTY (6th, 2012)). |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - |
[Rationale for the Classification] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, it is reported that it was negative in a bacterial reverse mutation test (HSDB (2008), REACH registration dossier (Accessed Sept. 2018)). |

8 | Specific target organ toxicity - Single exposure | Category 3 (Respiratory tract irritation) |
Warning |
H335 |
P304+P340
P403+P233 P261 P271 P312 P405 P501 |
[Rationale for the Classification] Based on the data in (1), it is not clear whether it was based on specific cases or case reports, but this substance is considered to be irritating to the respiratory tract in humans, and also from the data in (2), it is considered to produce respiratory organs irritation at higher concentrations. In addition, this substance is a corrosive liquid. Therefore, it was classified in Category 3 (respiratory tract irritation). Besides, the classification result was changed from the previous classification. [Evidence Data] (1) There is a description that inhalation in humans causes severe coughing and chest pain due to respiratory tract irritation and may result in lung edema, headache, nausea, and faintness (HSDB (2008)). (2) There is a report that as a result of inhalation exposure of rats to a mean concentration of 110 mg/L for up to 15 minutes, all the animals developed labored breathing, gasping, loss of equilibrium and forced movements after 10-12 minutes, and exposure was aborted after 15 minutes because the animals became prostrate (HSDB (2008)). (Note: The results of this study cannot be extrapolated to the guidance value because it is described in the GHS classification guidance for the Japanese Government that only data of exposure time not less than 30 minutes are used for classification. The calculated concentration is 21.3 mg/L (converted 4-hour equivalent value), corresponding to exceeding the range of Category 2). [Reference Data, etc.] (3) In a test in which 100-1,600 mg/kg was administered by gavage to mice, weakness, ataxia, and convulsions were observed at 1,600 mg/kg (HSDB (2008)). |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - |
[Rationale for the Classification] The target organ cannot be identified from the data in (1). In addition, since no other data are available for classification, it was classified as "Classification not possible" due to lack of data. [Evidence Data] (1) In a study in which rats were administered by feeding at doses of 75-300 mg/kg/day for 2 weeks, decreased body weight gain and food consumption were observed in males and females of the 300 mg/kg/day group, but it was pointed out that the decrease in food consumption may be due to palatability. At necropsy, findings such as dilation of the renal pelvis were observed in the kidney, but histopathological changes were not observed in the liver and kidney (HSDB (2008), PATTY (6th, 2012), REACH registration dossier (Accessed Sept. 2018)). |
