Hazard statement (code) |
Precautionary statement (code) |
Rationale for the classification | |
|---|---|---|---|---|---|---|
| 1 | Acute toxicity (Oral) | Not classified |
- |
- | - | There are two reports of LD50 values for rats of 1,600-3,200 mg/kg and 3,730 mg/kg (PATTY (6th, 2012)). One corresponds to Category 4 or "Not Classified" and the other corresponds to "Not Classified." The substance was classified as "Not Classified" (Category 5 in UN GHS classification) to which the larger number of values corresponds. |
| 1 | Acute toxicity (Dermal) | Not classified |
- |
- | - | Based on the report of the LD50 value of 6,472 mg/kg for rats (PATTY (6th, 2012)), this substance 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. There is a report of an LC50 value (4 hours) for rats of > 2,000 mg/m3 (PATTY (6th, 2012), ACGIH (7th, 2001)). However, it was not possible to identify the category from this value alone. Besides, since the LC50 value was lower than 90% of the saturated vapor pressure concentration (21,053 ppm), a reference value in the unit of ppm was applied as vapor without mist. Classification was conducted by using the lowest LC50 value in the rationale of the previous classification, therefore, the category was revised. |
| 1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Because LC50 values cannot be presumed from the data of the evidence of previous classification, the category was revised. |
| 2 | Skin corrosion/irritation | Not classified |
- |
- | - | Based on the description that it is considered that it shows mild irritation as a result of application of the undiluted solution of this substance to rabbits (ACGIH (7th, 2007)) and the description that mild irritation was observed as a result of application of this substance to guinea pigs (PATTY (6th, 2012)), the substance was classified as "Not Classified" (Category 3 in UN GHS classification). |
| 3 | Serious eye damage/eye irritation | Category 2 |
 Warning |
H319 | P305+P351+P338 P337+P313 P264 P280 |
There is a report that irritation was observed due to exposure of guinea pigs to the vapor of this substance (ACGIH (7th, 2007)) and a description that this substance showed mild to moderate irritation in rabbit eyes (PATTY (6th, 2012)). There is also a report that irritation was observed in human eyes due to exposure to the vapor of this substance (ACGIH (7th, 2007), PATTY (6th, 2012)). Based on the above, it was classified as Category 2. |
| 4 | Respiratory sensitization | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 4 | Skin sensitization | Classification not possible |
- |
- | - | Classification not possible due to lack of data. |
| 5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | Classification not possible due to lack of data. No in vivo data were available, and as for in vitro, a bacterial reverse mutation test was negative (NTP DB (Access on October 2015)). |
| 6 | Carcinogenicity | Classification not possible |
- |
- | - | Since there are no classification results by other organizations, classification is not possible due to lack of data. |
| 7 | Reproductive toxicity | Classification not possible |
- |
- | - | It is described that in a reproduction/developmental toxicity screening test by inhalation with rats, except that reduced activity was observed at the highest dose of 5.0 mg/L in parental animals, adverse effects were observed in none of pathological abnormalities in female and male genetic organs and effects on fertility in the parent animals, and the survival rate and the changes in body weight up to postnatal day 4 in pups (PATTY (6th, 2012)). However, it was not possible to classify as "Not classified" only by this result because this test is a screening test. Therefore, this substance was classified as "Classification not possible" due to lack of data. |
| 8 | Specific target organ toxicity - Single exposure | Category 3 (respiratory tract irritation, narcotic effects) |
Warning |
H335 H336 |
P304+P340 P403+P233 P261 P271 P312 P405 P501 |
This substance is irritating to the respiratory tract in humans (ACGIH (7th, 2007), PATTY (6th, 2012)). In experimental animals, there are reports of narcotic effects in inhalation exposure of rats and guinea pigs (ACGIH (7th, 2007), PATTY (6th, 2012)). Based on the above, it was classified in Category 3 (respiratory tract irritation, narcotic effects). |
| 9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | There is no information on repeated exposure to this substance in humans. In experimental animals, there is a description in a test in which rats were given this substance in drinking water for 13 months, at a dose exceeding Category 2 (10,000 ppm: 250-452 mg/kg/day), a transient suppression of body weight gain was observed, but there was no abnormality in clinical symptoms, organ weights, and pathological findings (PATTY (6th, 2012)) and there is a description in a neurotoxicity screening test in which rats were exposed by inhalation at 305 ppm for 17.5 weeks, central and peripheral nerve specimens were examined histopathologically but no abnormality was observed at the test concentration (converted guidance value: 1.84 mg/L/6 hr/day (exceeding the guidance value range of Category 2)). Based on the above, no significant toxicological effects were observed in the oral and inhalation routes, but the inhalation toxicity test was a screening test, and sufficient test items were not set, and neither test data were quoted in ACGIH (7th, 2007), therefore, it was classified as "Classification not possible" due to lack of data for this hazard class. |
| 10 | Aspiration hazard | Classification not possible |
- |
- | - | There are no cases of aspiration hazard in humans. However, this substance belongs to ketones composed of carbon atoms not less than 3 and not more than 13, and based on numerical data (viscosity: 0.473 mPa*s (25 deg C), density (specific gravity): 0.809 (20 deg C)) listed in HSDB (Access on August 2015), the calculated kinematic viscosity is 0.585 mm2/sec (25/20 deg C). Although it corresponds to Category 2 in the UN GHS classification, this substance was classified as "Classification not possible" according to the current guidance revised after the previous classification. |

|---|---|---|---|---|---|---|
| 11 | Hazardous to the aquatic environment (Acute) | Not classified |
- |
- | - | From 96-hour LC50 = 1210 mg/L for fish (Pimephales promelas) (HSDB, 2008), it was classified as "Not classified." |
| 11 | Hazardous to the aquatic environment (Long-term) | Not classified |
- |
- | - | Reliable chronic toxicity data were not obtained. Due to being not water-insoluble (water solubility = 43000mg/L, PHYSPROP Database, 2009), and "Not classified" in acute toxicity, it was classified as "Not classified." |
| 12 | Hazardous to the ozone layer | Classification not possible |
- |
- | - | No data available. |
