1 | Acute toxicity (Oral) | Not classified |
- |
- | - | There are 5 reports of LD50 values of 351 mg/kg (female), 426 mg/kg (male) (SIDS (2008)), 2,600 mg/kg (PATTY (6th, 2012), JECFA FAS (1973)), 3,470 mg/kg (male, female) (SIDS (2008)) and 4,300 mg/kg (PATTY (6th, 2012), ACGIH (7th, 2001)) for rats. Since 2 cases corresponded to Category 4, and 3 cases to "Not classified" (Category 5 in UN GHS classification), it was classified as "Not classified" (Category 5 in UN GHS classification) to which the larger number of data corresponded. |
1 | Acute toxicity (Dermal) | Category 3 |
Danger |
H311 |
P302+P352
P280 P312 P321 P361 P364 P405 P501 |
There are reports of an LD50 value of 500 mg/kg (male, female) for rabbits (PATTY (6th, 2012), SIDS (2008), ACGIH (7th, 2001)) and an LD50 value of 1,669 mg/kg for rats (female) (SIDS (2008)). Since it corresponded to Category 3 and Category 4, respectively, it was classified in Category 3 to which the smallest LD50 value corresponded. |
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. Although there is a report that in a test with rats exposed to the saturated vapor for 8 hours, no dead animals were observed (LC0 (8 hours) >3,850 ppm (converted 4-hour equivalent value: >5,445 ppm)) (SIDS (2008), ACGIH (7th, 2001)), it was not possible to judge which category the LC50 value corresponded to with this data alone, therefore, it was classified as "Classification not possible." Besides, based on the description that it is a test with the saturated vapour, the reference value in units of ppm was applied as a vapour without a mist. A new information source (SIDS (2008)) was added, and the category was revised. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Although there is a report of an LC50 value (1 hour) of >19.7 mg/L for rats (converted 4-hour equivalent value: > 4.9 mg/L) (SIDS (2008)), the category could not be specified, therefore, it was classified as "Classification not possible." Besides, since the LC50 value was higher than the saturated vapor concentration (11.7 mg/L), the reference value for a mist was applied. |

Since after application of 0.5 mL of the undiluted liquid of this substance to guinea pigs, mild to moderate edema, moderate to severe erythema and necrosis were observed at 2 hours after application, and necrosis was observed after 24 and 48 hours, it is considered to be corrosive (SIDS (2008)). In addition, there is a report that necrosis was observed after non-occlusive application of 0.01 mL of the undiluted liquid of this substance to rabbits for 24 hours (SIDS (2008), ACGIH (7th, 2001), PATTY (6th, 2012)). From the above results, it was classified in Category 1. Besides, this substance was classified as "C; R34" in the EU DSD classification, and as "Skin Corr. 1B H314" in the EU CLP classification. |
3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 |
P305+P351+P338
P280 P310 |
There are reports that severe eye damage was observed in an eye irritation test in which 0.05 mL of the undiluted liquid of this substance was applied to rabbits (SIDS (2008)), and that it was corrosive (IUCLID (2000)). Besides, this substance was classified in Category 1 for skin irritation/corrosion. From the above results, it was classified in Category 1. |
4 | Respiratory sensitization | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, although there was 1 case report of asthmatic symptoms in humans (ACGIH (7th, 2001)), details were unknown, therefore, the data were judged to be insufficient for classification. |
4 | Skin sensitization | Classification not possible |
- |
- | - | Classification not possible due to lack of data. Besides, although there is a report that no sensitization was observed in a maximization test with guinea pigs (IUCLID (2000)), details were unknown, therefore, the data were judged to be insufficient for classification. |
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, it was negative in a micronucleus test with Chinese hamsters (SIDS (2008), PATTY (6th, 2012)). As for in vitro, it was negative in bacterial reverse mutation tests and a sister chromatid exchange test with cultured mammalian cells (SIDS (2008), NTP DB (Access on September 2104), ACGIH (7th, 2001), PATTY (6th, 2012)). Besides, IUCLID information (in vivo dominant lethal test, in vivo and in vitro chromosomal aberration tests) described in the previous classification was excluded from the classification target because the test substance was different. |
6 | Carcinogenicity | Classification not possible |
- |
- | - | There are no carcinogenicity classification results by international organizations. Although there is a description that in a test in which this substance was administered by feeding to rats, forestomach neoplasia was observed. (PATTY (6th, 2012)), the details were unknown, therefore, classification was not possible due to lack of data. |
7 | Reproductive toxicity | Classification not possible |
- |
- | - |
Classification not possible due to lack of data. In teratogenicity tests with rats, mice, hamsters and rabbits by the oral route (feeding) of calcium propionate, no effects on maternal survival, fetal survival and litter size were observed, and no abnormalities in the fetal skeletal system were observed either (PATTY (6th, 2012), SIDS (2008)). From the above, although teratogenicity was not observed, there was not enough information on fertility, therefore, it was classified as "Classification not possible." |
8 | Specific target organ toxicity - Single exposure | Category 3 (Respiratory tract irritation) |

P403+P233 P261 P271 P312 P405 P501 |
This substance was irritating to the respiratory tract, and there is a report that cough and asthmatic response (stridor, etc.) were caused due to irritation to the respiratory mucosa by inhalation exposure in humans (SIDS (2008), ACGIH (7th, 2001), HSDB (Access on August 2014)). There were no data in experimental animals. From the above, it was classified in Category 3 (respiratory tract irritation). It was described that "irritation of the respiratory system was observed in rats following inhalation exposure for 4-hour (HSDB (2000))" in the previous classification, but this information could not be confirmed. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible |

There was no effect except that the urine showed slightly alkaline even if an adult male received the sodium salt of this substance up to 6,000 mg as a daily oral intake (JECFA FAS (1973), PATTY (6th, 2012)). As for experimental animals, in studies in which rats were fed for 3 months or dogs for about 100 days, irritative changes of the mucosa of the forestomach at 50,000 ppm in rats (about 2,500 mg/kg/day (conversion was the numerical value of ppm divided by 20)) and hyperplasia in the esophageal mucosa at 30,000 ppm in dogs (equivalent to 1,832-1,848 mg/kg/day) were observed, and no significant toxicological findings other than local effects were observed in any tests (SIDS (2008), EPA Pesticide (1990), PATTY (6th, 2012)). As in the above, based on the findings in humans and experimental animals, it corresponded to "Not classified" by the oral route, however, there was no toxicological information by the other routes, therefore, it was classified as "Classification not possible" due to lack of data. |

It was classified in Category 3 from 48-hour EC50 = 22.7 mg/L for crustacea (Daphnia magna) (SIDS, 2008). |
11 | Hazardous to the aquatic environment (Long-term) | Not classified |
- |
- | - | Reliable chronic toxicity data were not obtained. Classification for acute toxicity was conducted using the test results on this substance of the acid, classification is conducted using the data on the salt for chronic toxicity. Because it corresponds to "Not classified" in all tests on the calcium salt: an algae growth inhibition test (72-hour EbC > 500 mg/L for Desmodesmus subspicatus), a crustacea acute immobilization test (48-hour EC50 > 100 mg/L for Daphnia magna), and a fish acute toxicity test (96-hour LC50 > 10000 mg/L for Leuciscus idus) (SIDS, 2008), and both propionic acid (water solubility = 1000000 mg/L, PHYSPROP Database 2009) and calcium propionate (water solubility = 260 g/L, NITE 2014) are not water-insoluble, it was classified as "Not classified." |
