Rationale for the classification
1 Acute toxicity (Oral) *
-
-
- - [Rationale for the Classification]
Based on (1)-(3), it was classified as "Not classified."

(3) LD50 for rats: 3,200-6,400 mg/kg (PATTY (6th, 2012))
1 Acute toxicity (Dermal) *
-
-
- - [Rationale for the Classification]
Based on (1) and (2), it was classified as "Not classified."

[Evidence Data]
(1) LD50 for rabbits: >3.8 g/kg (3,800 mg/kg) (PATTY (6th, 2012))
(2) LD50 for rabbits: 5,000 mg/kg (HSDB (Access on October 2019))
1 Acute toxicity (Inhalation: Gases) *
-
-
- - [Rationale for the Classification]
Liquid (GHS definition). It was classified as "Not classified (Not applicable)."
1 Acute toxicity (Inhalation: Vapours) *
-
-
- - [Rationale for the Classification]
Based on (1), since the category could not be specified, it was classified as "Classification not possible."

[Evidence Data]
(1) An inhalation test with rats (8 hours): There were no dead animals at the saturated vapor concentration (0.306 mg/L) (converted 4-hour equivalent value: 0.612 mg/L) (PATTY (6th, 2012)).
1 Acute toxicity (Inhalation: Dusts and mists) *
-
-
- - [Rationale for the Classification]
Classification not possible due to lack of data.
2 Skin corrosion/irritation *
-
-
- - [Rationale for the Classification]
Based on (1)-(3), it was classified as "Not classified." The category was changed due to the new data obtained.

[Evidence Data]
(1) In a test in which this substance (520 mg) was applied under non-occlusive conditions to the skin of rabbits, slight irritation was observed (GESTIS (Access on October 2019)).
(2) No irritation was observed in a test in which a cloth soaked with this substance was applied to the skin of rabbits for 15 minutes or 20 hours (GESTIS (Access on October 2019), REACH registration dossier (Access on November 2019)).
(3) In a skin irritation test in which this substance was applied occlusively to rabbits for 72 hours according to the Draize method, the primary irritation indices (PII) were 0.17 (erythema) and 0 (edema) (REACH registration dossier (Access on November 2019)).

[Reference Data, etc.]
(4) In a test in which this substance (3.8 g/kg) was applied to the skin of rabbits, it showed moderate irritation (GESTIS (Access on October 2019)).
(5) Single application of this substance to rabbits caused moderate irritation (PATTY (6th, 2012)).
(6) In a study in which 0, 0.1, 0.2, or 0.5 mL this substance was applied to the skin of guinea pigs, an appearance of pain at the application site was observed, but irritation was slight (EPA PPRTV (2012)).
3 Serious eye damage/eye irritation *
-
-
- - [Rationale for the Classification]
Based on (1), it was classified as "Not classified." Besides, the category was changed due to the new data obtained.

[Evidence Data]
(1) In an eye irritation test (the Draize method) with rabbits of this substance, the mean scores for corneal opacity, iritis, conjunctiva redness and conjunctiva chemosis at 24/48/72 hours were 0, 0, 0.83 and 0.28, respectively, and all of these were fully reversible within 72 hours (REACH registration dossier (Access on November 2019)).

[Reference Data, etc.]
(2) Application of this substance (one drop: 50 mg) to the eyes of rabbits caused severe irritation, and vascular injection with formation of edema or necrotic changes in blood vessels were observed from 10 minutes to 8 days after application (GESTIS (Access on October 2019)).
(3) This substance might cause irritation to the eyes (HSDB (Access on October 2019)).
(4) This substance showed irritation to the mucous membranes following contact (GESTIS (Access on October 2019)).
4 Respiratory sensitization *
-
-
- - [Rationale for the Classification]
Classification not possible due to lack of data.
4 Skin sensitization *
-
-
- - [Rationale for the Classification]
Based on (1), it was classified as "Not classified."

[Evidence Data]
(1) In a mouse local lymph node assay (LLNA) according to OECD TG 429, SI values were below 3, and it was judged to be negative (REACH registration dossier (Access on November 2019)).
5 Germ cell mutagenicity *
-
-
- - [Rationale for the Classification]
There are no in vivo data. Therefore, classification was not possible due to lack of data.

[Evidence Data]
(1) As for in vitro, negative results were reported in bacterial reverse mutation tests (NTP DB (Access on October 2019), EPA PPRTV (2012)).
6 Carcinogenicity *
-
-
- - [Rationale for the Classification]
Based on classification results by other organizations in (1), it was classified as "Classification not possible" in accordance with the GHS Classification Guidance for the Japanese Government.

[Evidence Data]
(1) As for classification results by domestic and international organizations, it was classified as I (Inadequate Information to Assess Carcinogenic Potential) in the provisional evaluation by EPA (EPA PPRTV (2012)).

[Reference Data, etc.]
(2) In a combined chronic toxicity/carcinogenicity study in which rats and mice were given this substance by feeding for 78 weeks, no increase in the incidence of neoplastic lesions was observed. However, the duration of this study was shorter (normally 104 weeks), and it was considered to be insufficient information to evaluate the carcinogenicity of this substance (EPA PPRTV (2012)).
7 Reproductive toxicity *
-
-
- - [Rationale for the Classification]
Classification not possible due to lack of data.
8 Specific target organ toxicity - Single exposure *
-
-
- - [Rationale for the Classification]
Classification not possible due to lack of data.
9 Specific target organ toxicity - Repeated exposure *
-
-
- - [Rationale for the Classification]
Based on (1) and (2), as for the oral route, no effects were observed within the guidance range for Category 2 by administration to experimental animals. Therefore, it was classified as "Not classified." As for other routes, no data were available, and it was classified as "Classification not possible."

[Evidence Data]
(1) In a 78-week feeding toxicity study with male rats, reduced body weight gain was observed at or above 100 ppm (7 mg/kg/day, within the range of Category 1), and decreased red blood cell counts, white blood cell counts, and hemoglobin and hematocrit levels were observed at 3,000 ppm (221 mg/kg/day, exceeding Category 2) (EPA PPRTV (2012), HSDB (Access on October 2019)).
(2) In a 78-week feeding toxicity study with male mice, reduced body weight gain was observed at 3,000 ppm (539 mg/kg/day, exceeding Category 2) (EPA PPRTV (2012), HSDB (Access on October 2019)).
10 Aspiration hazard *
-
-
- - [Rationale for the Classification]
Classification not possible due to lack of data.
