1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible |
- |
- | - | [Rationale for the Classification] From (1), no dead animals were seen at 1.41 mg/L within a range for Category 4, but it was technically hard to set a dose near the upper limit for Category 4, and effects at the dose are unclear. Therefore, the classification is not possible. [Evidence Data] (1) LC50 for rats (4 hours) (OECD TG403, GLP): > 1.41 mg/L (the maximum possible concentration in the air, measured value) (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). |

2 | Skin corrosion/irritation | Not classified |
- |
- | - | [Rationale for the Classification] It was classified as "Not classified" from (1). [Evidence Data] (1) It is reported that in a skin irritation test with rabbits (n = 3) (OECD TG 404, GLP, semi-occlusive, 4-hour application, 72-hour observation), no skin irritation was seen (erythema/eschar score: 0/0/0, edema score: 0/0/0) (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). [Reference Data, etc.] (2) It is reported that in a skin irritation test with rabbits (n = 8) (semi-occlusive, 4-hour application, 72-hour observation), no erythema or edema was found in either an abraded skin group (4 animals) or an intact skin group (4 animals) at either 0.1% solution or 1% solution applied (NICNAS IMAP (2016)). |

3 | Serious eye damage/eye irritation | Category 1 |
Danger |
H318 | P305+P351+P338 P280 P310 |
[Rationale for the Classification] It was classified in Category 1 from (1). [Evidence Data] (1) It is reported that in an in-vitro eye irritation test (OECD TG 437), in vitro irritation score (IVIS) was 46.9, 2.3, 95.3 for a group treated with this substance (n = 3, 20% solution of this substance (saline), 2-hour application), a negative control group (n = 3, saline, 2-hour application), and a positive control group (n = 3, 20% solution of imidazole (saline), 2-hour application), respectively. The cut-off value for IVIS for Category 1 is > 55, but because in two samples from the group treated with this substance, upper cloudy layers of the cornea have sloughed, resulting in lower values, and corneal opacity was significantly high in one sample without sloughing, it was reported that if the sloughing were not so severe in the two samples, the overall IVIS would be predicted to be higher, and this substance was determined to cause serious eye damage (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). |

4 | Skin sensitization | Not classified |
- |
- | - | [Rationale for the Classification] It was classified as "Not classified" from (1), (2). [Evidence Data] (1) It is reported that in a maximization test in 27 persons (intradermal administration: 1% solution), low-grade irritation reactions were observed on the sites that were applied with an SLS solution before induction, but no reactions were seen on treated sites without SLS treatment, and there was no skin sensitization (NICNAS IMAP (2016)). (2) It is reported that in a local lymph node assay (LLNA) with mice (n = 5) (OECD TG 429), irritation index (SI values) was 1.54 (10%), 0.87 (25%), 2.64 (50%), an EC3 value could not be determined, and no skin irritation was seen (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). |

5 | Germ cell mutagenicity | Not classified |
- |
- | - | [Rationale for the Classification] Based on the data of (1) to (4), it was classified as "Not classified." [Evidence Data] (1) In a bacterial reverse mutation assay (OECD TG 471), negative results were reported (NICNAS IMAP (2016)). (2) In an in vitro mammalian cell gene mutation test (OECD TG 476, MLA), negative results were reported (NICNAS IMAP (2016)). (3) In a chromosomal aberration test (OECD TG 473, GLP) using cultured human lymphocytes, for continuous treatment in the absence of a metabolic activation system, positive results were reported (while for short-time treatment, regardless of the presence or absence of a metabolic activation system, negative results were reported) (NICNAS IMAP (2016)). (4) In a micronucleus test (OECD TG 487, GLP) using cultured human lymphocytes, for continuous treatment in the absence of a metabolic activation system, negative results were reported (REACH registration dossier (2014)). |

7 | Reproductive toxicity | Category 2 |
Warning |
H361 | P308+P313 P201 P202 P280 P405 P501 |
[Rationale for the Classification] Based on (1), it was classified in Category 2. [Evidence Data] (1) It was reported that in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test by feeding administration with rats (OECD TG422, GLP, for minimum of five consecutive weeks from two weeks prior to pairing (males), and from two weeks prior to pairing, throughout pairing, during gestation and until day 6 of lactation (females)), lower body weight and food consumption (males and females), reduced heart and ovary weights (females) and lower number of implantations and mean litter size were observed in parental animals at 15,000 ppm, while reduced body weight gain was observed in the offspring (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). |

8 | Specific target organ toxicity - Single exposure | Not classified |
- |
- | - | [Rationale for the Classification] Based on (1) and (2), it was classified as "Not classified." [Evidence Data] (1) It was reported that in an acute inhalation (dust) toxicity test (OECD TG403, GLP) with rats, at 1.41 mg/L (within the guidance value range for Category 2), increased respiratory rate, hunched posture and pilo-erection were observed and there were isolated cases of red/brown staining to the eyes and/or snout (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). (2) In an acute oral toxicity study and an acute dermal toxicity test with mice, there was no finding that should be adopted as a rationale for the classification (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible |
- |
- | - | [Rationale for the Classification] Based on (1) and (2), it was considered as "Not classified" in the oral route. However, there was no information on toxicity in the inhalation route, and it was judged as "Classification not possible due to lack of data." [Evidence Data] (1) It was reported that in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test (OECD TG422, GLP) by feeding administration with rats (for minimum of five consecutive weeks from two weeks prior to pairing (males), and from two weeks prior to pairing, throughout pairing, during gestation and until day 6 of lactation (females)), transient lower body weight and food consumption attributed to the palatability of the feed (males and females) and thymic involution (females) were observed at 15,000 ppm (approximately 1,000 mg/kg/day, converted guidance value: 750 mg/kg/day, in the range corresponding to "Not classified") (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). (2) In a 90-day feeding study with rats, at 2,000 mg/kg/day (in the range corresponding to "Not classified"), lower body weight, decreased motor activity and drowsiness (during the first 15 days of feeding) were reported (NICNAS IMAP (2016), REACH registration dossier (Accessed May 2020)). |
