Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified |
- |
- | - | Based on a report of an LD50 value of 2,060 mg/kg for rats (ACGIH (7th, 2001)), it was classified as "Not classified" (Category 5 in UN GHS classification). According to the GHS classification guidance for the Japanese government, the category was changed from the previous classification. |
1 | Acute toxicity (Dermal) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Since the data of IUCLID (2000) used in the previous classification could not be obtained and could not be confirmed, it was not used. Therefore, the classification result was changed from the previous classification. Besides, there is a report of the minimum lethal dose value of 2,200-2,600 mg/kg for rabbits (PATTY (6th, 2012)), which exceeds the guidance value range for Category 4. |
1 | Acute toxicity (Inhalation: Gases) | Not applicable |
- |
- | - | Solid (GHS definition). Besides, since the melting point is 25.93 deg C (HSDB (Access on June 2017)), it is considered to be a liquid at higher temperatures than that. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible |
- |
- | - |
Solid (GHS definition). However, since the melting point is 25.93 deg C (HSDB (Access on June 2017)), it is considered to be a liquid at higher temperatures than this. There is a report of > 3.6 mg/L (> 882 ppm) as an LD50 value in a 4-hour inhalation exposure test with rats (HSDB (Access on June 2017)). However, because it is not possible to specify a category by this value alone, it was classified as "Classification not possible." Besides, since the exposure concentration is lower than 90% of the saturated vapor pressure concentration (1,287 ppm), a reference value in units of ppm was applied as vapor with little mist. |

Based on a description that it is slightly irritating to human skin (ACGIH (7th, 2001), PATTY (6th, 2012)), and a description that this substance is irritating to the skin in short term exposure (HSDB (Access on June 2017)), it was considered to be an irritant, therefore, it was classified in Category 2. Besides, this substance is classified as "Skin Irrit. 2, H315" in the EU CLP classification (ECHA CL Inventory (Access on June 2017)). The category was changed by re-evaluating the contents of the information source. |
3 | Serious eye damage/eye irritation | Category 1 |
Danger |

P305+P351+P338
P280 P310 |
Based on a report that in a test in which this substance was applied to the eyes of rabbits (OECD TG 405 compliant), moderately severe irritation and reversible corneal injuries were observed (ACGIH (7th, 2001)), and a report that in another test with rabbits, the scores of corneal opacity in 4 animals after 4, 24, 48, 72 hours were all 3, and one animal did not recover from injury after 21 days (ECETOC TR48 (2) (1998)), it was classified in Category 1. |
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. Besides, though there is a report that no sensitization was observed in a human patch test (containing 4% of this substance in petrolatum) (PATTY (6th, 2012)), it was not adopted because the details of the test were unknown. |
5 | Germ cell mutagenicity | Classification not possible |
- |
- | - | The substance was classified as "Classification not possible" because it was not possible to classify a substance as "Not classified" according to the revised GHS classification guidance for the Japanese government. As for in vivo, a mouse bone marrow micronucleus test was negative (PATTY (6th, 2012)). As for in vitro, bacterial reverse mutation tests were negative (ACGIH (7th, 2001), PATTY (6th, 2012), NTP DB (Access on July 2017)). |

There is a description that after two strains of mice were dosed by feeding (0.1-1.0%) through the period of gestation and lactation over several generations, in both of the strains, a significant increase in mortality (14.1-53.5%) and slightly inhibited growth during 21 days after birth were observed at a high dose (1.0%) in the pups (ACGIH (7th, 2001), Environmental Risk Assessment for Chemical Substances Vol.8, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2010), PATTY (6th, 2012)). Since effects on the next generation were observed in the situation where the general toxicity effects on parental animals were unknown, it was classified in Category 2. |
8 | Specific target organ toxicity - Single exposure | Category 3 (respiratory tract irritation, narcotic effects) |

As for humans, there is a report that irritation of the nose and throat was observed by inhalation exposure to 100 ppm of this substance for 3-5 minutes in a volunteer study (OEL Documentations (Japan Society For Occupational Health (JSOH), 1970), PATTY (6th, 2012)). As for experimental animals, there is a report that in a single dermal exposure test with rabbits, although the doses were not described, the animals showed tremors, narcosis, and hypothermia and died in an application to extensive skin areas at high concentrations (PATTY (6th, 2012)). Therefore, it was classified in Category 3 (respiratory tract irritation, narcotic effects). |

As for humans, there is a report that nonspecific disturbances in the autonomic nervous system were observed in 114 of 453 men and women who had been exposed at concentrations below the permitted level for 2 years, and similar symptoms were observed only in 8 people in the control group (100 people) (ACGIH (7th, 2001)). As for experimental animals, there is a report that in a 10-week inhalation toxicity test with rabbits, within the guidance value range for Category 2, slight degenerations were observed in the liver and kidney at 145 ppm (converted guidance value: 0.33 mg/L), and degenerations in the cardiac muscle, liver and kidney were observed at 272 ppm (converted guidance value: 0.62 mg/L) (PATTY (6th, 2012), Environmental Risk Assessment for Chemical Substances Vol.8, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2010)). In addition, there is a report that in a 40-day repeated oral dose toxicity test with male rabbits, decreases in the testes and testes weight, inhibition of spermatogenesis, decreases in the diameter of the seminiferous tubules and the volume of the Leydig cell nucleus, sperm deficiency in the lumen of the epididymis and vas deferens, etc. were observed at 25 mg/kg/day (converted guidance value: 11.1 mg/kg/day) within the guidance value range for Category 2 (Environmental Risk Assessment for Chemical Substances Vol.8, Tentative Hazard Assessment Sheet (Ministry of the Environment, 2010)). This was a test with one dose and effects at doses lower than this were unknown, however, the effects were observed in the testes within the guidance value range for Category 2. From the above, it was classified in Category 1 (autonomic nervous system) and Category 2 (heart, liver, kidney, genetic organs (men)). |
