-
-
- - Solid (GHS definition)

9 Pyrophoric liquids Not applicable
-
-
- - Solid (GHS definition)
10 Pyrophoric solids Classification not possible
-
-
- - No data available.

Rationale for the classification
1 Acute toxicity (Oral) Not classified
-
-
- - It was classified as "Not classified" based on a report on an LD50 value of > 10,000 mg/kg for rats (SIDS (2004)).
1 Acute toxicity (Dermal) Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, in SIDS (2004), assessment on a category was conducted using data on benzoic acid (CAS: 65-85-0), the free acid of this substance, and there is a report on an LD50 value of > 2,000 mg/kg for rabbits for benzoic acid. It is described in SIDS (2004) that the loss of acidity due to the potassium salt should decrease its toxicity.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Solid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Not applicable
-
-
- - Solid (GHS definition)
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, in SIDS (2004), assessment on a category was conducted using data on benzoic acid (CAS: 65-85-0), the free acid of this substance, and there is a report on a 4-hour LC50 value (dust) of > 12.2 mg/L for rats for benzoic acid. It is described in SIDS (2004) that the loss of acidity due to the potassium salt should decrease its toxicity.
2 Skin corrosion/irritation Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, it is reported in SIDS (2004) that sodium benzoate was not irritating in a skin irritation test (OECD TG 404), and this substance, the potassium salt, was assessed to be not irritating.
3 Serious eye damage/eye irritation Classification not possible
-
-
- - Classification not possible due to lack of data.
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
-
-
- - It 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. There are no data on this substance, but because it is described that data on sodium benzoate are available representing potassium benzoate (SIDS (2004)), the information on sodium benzoate was used for classification this time. Regarding sodium benzoate, as for in vivo, it was negative in a chromosomal aberration test with rat bone marrow cells and a dominant lethal test with rats, and as for in vitro, it was negative in a bacterial reverse mutation test and a chromosomal aberration test with cultured human embryonic lung cells and positive in a chromosomal aberration test with Chinese hamster CHL cells without S9, therefore it was judged to be not mutagenic. From the above, this substance was assessed to be not mutagenic (SIDS (2004)).
6 Carcinogenicity Classification not possible
-
-
- - Classification not possible due to lack of data. There are no carcinogenicity data on this substance. Besides, no carcinogenicity was found in long term carcinogenicity tests with rats and mice for sodium benzoate (CAS: 532-32-1) and benzyl alcohol (CAS: 100-51-6) (SIDS (2004), JECFA 557 (Access on September 2013)).
7 Reproductive toxicity Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, for sodium benzoate (CAS: 532-32-1), neither maternal toxicity nor developmental toxicity was observed in developmental toxicity tests with rats, mice, rabbits, and hamsters in the oral route (gavage) (SIDS (2004)). There are no test reports on fertility.
8 Specific target organ toxicity - Single exposure Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, as for sodium benzoate (CAS: 532-32-1) and benzyl alcohol (CAS: 100-51-6), no clear toxicity effects were seen after 4-hour inhalation exposure (dust or mist, 4-12 mg/L) (SIDS (2004)).
9 Specific target organ toxicity - Repeated exposure Classification not possible
-
-
- - Classification not possible due to lack of data. Besides, as for sodium benzoate (CAS: 532-32-1), in a 90-day diet administration test with rats and a 35-day drinking water administration test with mice, no toxicity effects were observed even after exposure to the higher doses (1,167-3,145 mg/kg/day) above the guidance value range for Category 2 (SIDS (2004)), and the substance corresponds to "Not classified" in the oral route.
10 Aspiration hazard Classification not possible
-
-
- - Classification not possible due to lack of data.
