4 | Skin sensitization | Not classified |
- |
- | - | [Rationale for the Classification] Based on (1) and (2), it was classified as "Not classified." [Evidence Data] (1) In a skin sensitization test (maximization method) according to OECD TG 406 with guinea pigs, no skin reaction was observed, and it was concluded to be negative (REACH registration dossier (Accessed on September 2019)). (2) This substance is not irritating to the skin and slightly irritating to the eyes. Sensitising effects are highly unlikely (SIDS (2006)). [Reference Data, etc.] (3) It was reported that irritation was induced in only one in a human repeated insult skin sensitisation test on 61 volunteers. However, the validity of this report was not assessed (SIDS (2006), REACH registration dossier (Accessed on September (2019))). |

5 | Germ cell mutagenicity | Not classified |
- |
- | - | [Rationale for the Classification] There is no in vivo data for this substance, however, based on the weight of evidence (WoE), according to (1), it was classified as "Not classified." [Evidence Data] (1) As for in vitro, there are reports of negative results in a bacterial reverse mutation test and a mammalian cell chromosomal aberration test (SIDS (2006), Risk Assessment Report (Food additives)_Potassium sulfate (Food Safety Commission, 2013)). It is concluded, as a comprehensive decision, in the evaluation in Risk Assessment Report (Food additives) (Food Safety Commission, 2013) that the food additive "potassium sulfate (CAS RN 7778-80-5)" has no genotoxicity of any particular concern for living organisms since negative results were obtained in all tests using salts of sulfuric acid. |

FY2019 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
7 | Reproductive toxicity | Classification not possible |
- |
- | - | [Rationale for the Classification] Since only a little information on developmental effects as in (1) and (2) was obtained, and there are no data on sexual function and fertility, it was classified as "Classification not possible" due to lack of data. [Reference Data, etc.] (1) In a developmental toxicity test in which female mice were administered at a very high dose of 2,800 mg/kg/day by gavage on gestational day 8 through 12, no abnormality was observed in maternal animals, and no teratogenicity, etc. were observed. Besides, increased body weight in pups on postnatal Day 1 was observed, but no difference was observed on postnatal Day 3 (SIDS (2006)). (2) In a developmental toxicity test in which female mice were dosed on a gestational day 8 or 9 by a single subcutaneous injection (60 mg/kg), increases in maternal weight gain and delayed ossifications in fetuses were observed (SIDS (2006)). |

Danger |
H370 | P308+P311 P260 P264 P270 P321 P405 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 1 (gastrointestinal tract). [Evidence Data] (1) This substance was once used as a laxative in humans for medical purposes in oral doses of about 300 mg/kg up to 20 g maximum, but it has been gradually abandoned due to severe diarrhea and abdominal cramping (SIDS (2006)). |
FY2019 | GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1)) |
9 | Specific target organ toxicity - Repeated exposure | Not classified |
- |
- | - | [Rationale for the Classification] Based on (1) and (2), it was classified as "Not classified" for the inhalation and oral routes. [Evidence Data] (1) In a cross-sectional study among 119 male workers exposed to the dust of this substance for 2 months to 31 years, mean urinary excretion of inorganic sulfates exceeding 2.2 g/L in all workers was detected, and 30% of the workers excreted more than 3 g/day of inorganic sulfates. The only symptom indicated by the workers was nasal irritation and runny noses (SIDS (2006)). (2) In a 4-week feeding study with male rats, no toxic effects were observed at up to the highest dose of ca. 2,000 mg/kg/day (SIDS (2006)). |
