HEALTH HAZARDS

Hazard class		Classification	Pictogram Signal word	Hazard statement (code)	Precautionary statement (code)	Rationale for the classification	Classification year (FY)	GHS Classification Guidance for the Japanese Government
1	Acute toxicity (Oral)	Not classified	- -	-	-	[Rationale for the Classification] Based on (1), it was classified as "Not classified." Besides, as for (2) and (3), isomer ratio information is unknown. [Evidence Data] (1) LD50 for male rats (Nonoxynol-4 (p-isomer)): 7,400 mg/kg (CIR (Cosmetic Ingredient Review) Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)). [Reference Data, etc.] (2) LD50 for male rats: 4,300 mg/kg (J. Am. Coll. Toxicol., 2, 35-60 (1983)). (3) LD50 for rats: 4,290-7,400 mg/kg (Canada PS Assessment report (2001)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	Not classified	- -	-	-	[Rationale for the Classification] Based on (1), it was classified as "Not classified" (Category 5 in UN GHS classification). Besides, as for (2), isomer ratio information is unknown. [Evidence Data] (1) LD50 for rabbits (Nonoxynol-4 (p-isomer)): 2,550-2,575 mg/kg (calculated value from LD50: 2.5 mL/kg (J. Am. Coll. Toxicol., 2, 35-60 (1983)) and specific gravity: 1.02-1.03 (CIR Expert Panel (2016))) [Reference Data, etc.] (2) LD50 for rabbits: > 2,000 mg/kg (Canada PS Assessment report (2001))	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	[Rationale for the Classification] Liquid (GHS definition)	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	[Rationale for the Classification] Based on (1), it was classified as "Not classified." Besides, although the saturated vapor concentration of this substance is unknown, the reference value as mist was applied based on the description that the test was conducted with 1% aerosol (with aqueous dispersant). [Evidence Data] (1) LC50 for rats (8 hours): > 21.7 mg/L (calculated from 0.0213 mL/L and specific gravity: 1.02-1.03, converted 4-hour equivalent value: > 43.4 mg/L, there was no death at 21.7 mg/L) (J. Am. Coll. Toxicol., 2, 35-60 (1983), CIR Expert Panel (2016))	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
2	Skin corrosion/irritation	Category 2	Warning	H315	P302+P352 P332+P313 P362+P364 P264 P280 P321	[Rationale for the Classification] Based on (1) and (2), it was classified in Category 2. Besides, although there are data (3) and (4) which showed this substance is not irritating to the skin, the reliability of these data is compared with the reliability of data (1) and (2), resulting in the judgment above based on the weight of evidence. [Evidence Data] (1) There is a report that as a result of repeated occlusive applications (3 times/week for 3 weeks, induction phase) of a 10% solution of Nonoxynol-4 (p-isomer) (in mineral oil) for 48 hours to the dorsal skin of 111 humans (10 men and 101 women), very slight to moderate erythema was observed in 36/111 (32.4%) (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983), Canada PS Assessment report (2001)). (2) There is a report that in a skin irritation test with rabbits, as a result of an occlusive application of nonoxynol-4 (p-isomer) for 24 hours, in the 0.5 mL application group (n = 6) well-defined to severe erythema and slight to severe edema were observed in all the animals, and the primary irritation index (PII) was 5.58 based on the average score of erythema and edema at 24, 72 hours after the start of exposure (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)). (3) There is a report that in an irritation test in which undiluted Nonoxynol-4 (p-isomer) was applied to the dorsal skin of humans (each 25 men and women) for 48 hours at the first time and then 14 times every 24 hours repeatedly, no irritation was observed (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)). (4) There is a report that in a skin irritation test with rabbits, as a result of an occlusive application of nonoxynol-4 (p-isomer) for 24 hours, in the 0.01 mL application group (n = 5), no irritation was observed (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Category 2A	Warning	H319	P305+P351+P338 P337+P313 P264 P280	[Rationale for the Classification] Based on (1), it was classified in Category 2A according to the GHS Classification Guidance for the Japanese Government. Besides, (2) and (3) were not used for the classification judgement since in (2), the observation period was 24 hours, and in (3), the test substance concentration was low. [Evidence Data] (1) There is a report that in an eye irritation test (n = 6) with rabbits, as a result of application of undiluted 4-nonoxynol (p-isomer) solution, moderate irritation was observed in the cornea, iris, and conjunctiva, and did not resolve completely even after 7 days (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)). [Reference Data, etc.] (2) There is a report that in an eye irritation test (n = 5) with rabbits, as a result of application of the undiluted liquid of this substance, moderate irritation was observed after 24 hours (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)). (3) There is a report that in an eye irritation test (n = 6) with rabbits, as a result of application of a 5% preparation of this substance (moisturizing lotion), little irritation was observed (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Respiratory sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
4	Skin sensitization	Classification not possible	- -	-	-	[Rationale for the Classification] In tests on humans, there are reports (1) of no sensitization and (2) that sensitization was observed in a small number of people. However, it was judged that there is no evidence sufficient to judge whether it will be classified or not, and it was classified as "Classification not possible." [Reference Data, etc.] (1) There is a report as follows: the undiluted solution of Nonoxynol-4 (p-isomer) was applied to the dorsal skin of humans (each 25 men and women) for 48 hours at first and then 14 times every 24 hours repeatedly; although a response was provoked by 24-hour re-application 2 weeks after discontinuation of the application, no sensitization was observed (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)). (2) There is a report as follows: a 10% solution of nonoxynol-4 (p-isomer) (in mineral oil) was occlusively applied to the dorsal skin of 111 humans (10 men and 101 women) for 48 hours repeatedly (3 times/week for 3 weeks; induction phase), and after 2 weeks an occlusive patch (challenge) was applied for 48 hours; very slight to moderate erythema was observed in 36/111 subjects, and 3/36 subjects were diagnosed of allergic contact dermatitis; when retested (applied for 30 minutes) to the three subjects, allergic reaction was reproduced in only 1/3 subjects, and reaction was slight (CIR Expert Panel (2016), J. Am. Coll. Toxicol., 2, 35-60 (1983)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
5	Germ cell mutagenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1) and (2), it was classified as "Classification not possible" in accordance with the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) As for in vivo, Nonoxynol-4 (isomer ratio is unknown) is reported as negative in a micronucleus test (intraperitoneal administration) with mouse bone marrow cells (Canada PS Assessment report (2001)). (2) As for in vitro, as for Nonoxynol-4 (isomer ratio is unknown), there are negative reports in both a bacterial reverse mutation test and an unscheduled DNA synthesis (UDS) test with rat primary hepatocytes (Canada PS Assessment report (2001)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	[Rationale for the Classification] There are no available reports on humans for carcinogenicity. As for experimental animals, carcinogenicity is not reported for Nonoxynol-4 in (1) although the isomer ratio is unknown. In addition, there are also no classification results by domestic and international organizations. Therefore, it was classified as "Classification not possible" for this hazard class. [Evidence Data] (1) When Nonoxynol-4 (isomer ratio is unknown) was administered by feeding to rats at 200 mg/kg/day and to dogs at 40 mg/kg/day for 2 years, no carcinogenicity was observed (J. Am. Col. Toxicol., 2, 35-60 (1983), Canada PS Assessment report (2001), CIR Expert Panel (2016)). (2) There are no classification results by domestic and international organizations.

7	Reproductive toxicity	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. Besides, (1) couldn't be used for classification since the doses where symptoms were observed are unknown. [Reference Data, etc.] (1) There is a report that in a single dermal dose test (dose: 1,020 mg/kg-6,798 mg/kg) with rabbits, erythema and necrosis of the skin were observed at various doses, and in dead animals, congestion and bleeding of the lung were observed (J. Am. Coll. Toxicol., 2, 35-60 (1983)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1) and (2), this substance corresponds to "Not classified" by the oral route, but toxicity information on other routes is insufficient. Therefore, it was classified as "Classification not possible." [Evidence Data] (1) In tests in which Nonoxynol-4 (p-isomer) was administered by feeding to rats or dogs for 90 days, no effects were observed at doses within the range of Category 2, and growth retardation and increased liver weights in rats at 1,000 mg/kg/day and increased liver weights in dogs at 200 mg/kg/day were only observed (J. Am. Col. Toxicol., 2, 35-60 (1983), CIR Expert Panel (2016)). (2) In tests in which Nonoxynol-4 (p-isomer) was administered by feeding to rats or dogs for 2 years, no effects were observed at doses within the range of Category 2, and reduced body weights and enlarged liver in rats at 1,000 mg/kg/day and reduced body weights, vomiting, and increased serum ALP activity in dogs at 1,000 mg/kg/day were only observed (J. Am. Col. Toxicol., 2, 35-60 (1983), CIR Expert Panel (2016)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
10	Aspiration hazard	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
