Hazard statement (code) |
Precautionary statement (code) |
Rationale for the classification | |
|---|---|---|---|---|---|---|
| 1 | Acute toxicity (Oral) | Not classified |
- |
- | - | Based on reports of LD50 values for rats of 5,140 mg/kg (HSDB (Access on June 2017)) and 5,800 mg/kg (PATTY (6th, 2012)), it was classified as "Not classified." |
| 1 | Acute toxicity (Dermal) | Not classified |
- |
- | - | Based on a report of an LD50 value of > 2,150 mg/kg (PATTY (6th, 2012), HSDB (Access on June 2017)) for rats, it was classified as "Not classified." |
| 1 | Acute toxicity (Inhalation: Gases) | Not applicable |
- |
- | - | Liquid (GHS definition) |
| 1 | Acute toxicity (Inhalation: Vapours) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified |
- |
- | - | Based on a report of an LC50 value of 1,220 ppm (8.19 mg/L) (PATTY (6th, 2012), HSDB (Access on June 2017)) in a 4-hour inhalation exposure test with rats, it was classified as "Not classified." Besides, the reference values in the unit of mg/L as mist were applied because the LC50 value is higher than the saturated vapor pressure concentration (56.8 ppm). |
| 2 | Skin corrosion/irritation | Category 2 |
 Warning |
H315 |
P302+P352
P332+P313 P362+P364 P264 P280 P321 |
Based on descriptions that in a skin irritation test with rabbits, the Draize score was 5.2/8, and it was moderately irritating to the skin (PATTY (6th, 2012)), and that it is moderately to severely irritating to the skin in humans (HSDB (Access on June 2017)), it was classified in Category 2. Besides, this substance was classified as "Skin Irrit. 2, H315" in EU CLP classification (ECHA CL Inventory (Access on June 2017)). |
| 3 | Serious eye damage/eye irritation | Category 2B |
Warning |
H320 |
P305+P351+P338
P337+P313 P264 |
Based on a description that in an eye irritation test with rabbits, slight irritation was shown and resolved rapidly (PATTY (6th, 2012)), it was classified in Category 2B. The category was revised based on the information obtained in this investigation. |
| 4 | Respiratory sensitization | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 4 | Skin sensitization | Category 1 |
Warning |
H317 |
P302+P352
P333+P313 P362+P364 P261 P272 P280 P321 P501 |
As for humans, there are descriptions that two out of four laboratory technicians with occupational contact dermatitis were positive in a patch test, and that in patch tests of workers who were regularly exposed to epoxy resins and solvents and have a history of skin pruritus and pharyngeal stenosis, etc., urticarial reactions to this substance were seen 30 minutes after application, and urticarial reactions accompanied by tingling of the pharynx and hoarseness were also observed in the retest (both in HSDB (Access on June 2017)). As for guinea pigs, there is a description that it was a potent skin sensitizer (PATTY (6th, 2012)). From the above, it was classified in Category 1. Besides, this substance was classified as "Skin Sens. 1, H317" in the EU CLP classification (ECHA CL Inventory (Access on June 2017)). |
| 5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | This substance is a mixture (mixture ratio is unknown) of the isomers (ortho (CAS RN 2210-79-9), meta (CAS RN 2186-25-6), para (CAS RN 2186-24-5)). As for in vivo, gene mutation tests in which the ortho isomer was dermally applied to transgenic mice (MutaTM mice) were negative in cells of the bone marrow, liver, and skin, and micronucleus tests with mouse bone marrow cells were negative (PATTY (6th, 2012), HSDB (Access on June 2017)). As for in vitro, bacterial reverse mutation tests with this substance, the ortho isomer, and the para isomer were all positive (PATTY (6th, 2012), HSDB (Access on June 2017)). From the above, it was classified as "Classification not possible" according to the GHS classification guidance for the Japanese government. |
| 6 | Carcinogenicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 7 | Reproductive toxicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, the details are unknown, but there is a description that toxicity on the reproductive organs and fetuses was observed after inhalation exposure at concentrations lower than the level with a general toxic effect (2.55 mg/m3) (HSDB (Access on June 2017)). |
| 8 | Specific target organ toxicity - Single exposure | Classification not possible |
- |
- | - | Classification not possible due to lack of data. There is no data on single exposure to this substance in humans. As for experimental animals, there is a report that in a single oral dose test with rats, although no details of dosages are described, hepatic congestion was observed on necropsy in addition to dyspnea and lacrimation (PATTY (6th, 2012)). Since the LD50 value in this test was reported to be 5,800 mg/kg exceeding Category 2, it is considered that the effect was observed at doses within or above the range for Category 2 near the LD50 value, but a target organ cannot be specified from this information alone. In addition, there are reports that in rats, mice and guinea pigs, as the symptoms of acute toxicity of this substance, central nervous system inhibition, increased respiratory rate, and myasthenia were shown, deaths occurred within 8 days, and liver damage and necrosis of the renal tubular epithelium were observed on necropsy (HSDB (Access on June 2017)). However, there are no descriptions of the exposure route and dosages, and it is insufficient as evidence for the classification. Therefore, it was classified as "Classification not possible." |
| 9 | Specific target organ toxicity - Repeated exposure | Category 1 (respiratory organs) |
 Danger |
H372 |
P260
P264 P270 P314 P501 |
No information on humans is available. As for experimental animals, in a 3-week toxicity test with rats exposed by inhalation (6 hours/day, 5 days/week), inflammation and ulceration of the nasal cavity, decreased feed consumption, suppression of body weight gain, dyspnea, and exophthalmos were observed at or above 53 mg/m3 (0.0088 mg/L) within the guidance value range for Category 1 (PATTY (6th, 2012)). Therefore, it was classified in Category 1 (respiratory organs). The classification result was different from the previous classification since a new information source was used. |
