[Reference Data, etc.] (2) There is also a report that it is irritating to the eyes (HSDB (2002)), but detail information is unknown.	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))

In addition, based on (5), it was classified in Category 1B. Besides, the category was changed from the previous classification by using new information sources. [Evidence Data] (1) Among dentists and dental assistants who handled dental materials containing this substance, sensitization reactions to this substance are reported in 8 of 9 of them with allergic contact dermatitis (MAK/BAT (1999)). (2) Sensitization reactions (Type IV) to this substance are reported in 15 of 35 dental technicians with occupational allergic contact eczema (MAK/BAT (1999)). (3) In case reports on patients with allergic contact dermatitis, the sensitizing potential of this substance was indicated in patch tests of this substance (MAK/BAT (1999)). (4) There is a report that moderate to severe sensitization was observed in a maximization test (n=10 animals/group) with guinea pigs (MAK/BAT (1999)). (5) There is a report that in a maximization test with guinea pigs, after induction of sensitization with 1%, 5% or 10% preparations (in olive oil) of this substance, sensitization reactions were observed in 4/7 animals (57%), 12/14 animals (86%) and 19/22 animals (86%) by re-application (MAK/BAT (1999)). [Reference Data, etc.] (6) Patch tests with various substances including this substance were conducted on 82 workers who are suspected to be sensitized by exposure to acrylic acid, and sensitization is reported in 11 subjects (13.4%), but the further details are unknown (MAK/BAT (1999)).

5	Germ cell mutagenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1)-(4), it was classified as "Classification not possible" according to the GHS Classification Guidance for the Japanese Government. [Evidence Data] (1) As for in vivo, there is a report that it was negative in a micronucleus test with mice (REACH registration dossier (Accessed Sept. 2018)). (2) As for in vivo, there is a report that it was negative in an unscheduled DNA synthesis test with rat liver (REACH registration dossier (Accessed Sept. 2018)). (3) As for in vitro, there is a report that it was negative in a mouse lymphoma test (HSDB (2002)) (4) As for in vitro, there is a report that it was positive in a chromosomal aberration test with cultured human lymphocytes (REACH registration dossier (Accessed Sept. 2018)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
6	Carcinogenicity	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. [Reference Data, etc.] (1) As for ethylene glycol (CAS RN 107-21-1), the ester hydrolysate of this substance, an oral carcinogenicity study with mice showed that there was no evidence of carcinogenicity (REACH registration dossier (Accessed Sept. 2018)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Classification not possible	- -	-	-	[Rationale for the Classification] There are the data in (1) only and no reproductive test data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) There is a report that in a developmental toxicity test in which rats of gestational days 6-20 were dosed by gavage, no developmental effect on the fetuses was observed at up to 500 mg/kg/day where maternal toxicities (deterioration of general condition, transient body weight loss and decreased food consumption) were manifested (REACH registration dossier (Accessed Sept. 2018), GESTIS (Accessed Sept. 2018)).	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] Toxicity findings by which specific organs were regarded as target organs were not obtained from the results of available studies. Therefore, it was classified as "Classification not possible" for this hazard class. [Evidence Data] (1) In a single administration test with rats given this substance by gavage, doses used were extremely high, and there are no findings available for classification at doses up to the range of Category 2 (REACH registration dossier (Accessed Sept. 2018)). (2) In a single dermal application test of this substance with rats, only irritation effects at the application site were observed (REACH registration dossier (Accessed Sept. 2018)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
9	Specific target organ toxicity - Repeated exposure	Category 1 (respiratory organs)	Danger	H372	P260 P264 P270 P314 P501	[Rationale for the Classification] Based on the data in (1), it was classified in Category 1 (respiratory organs). Besides, it is described in the GHS Classification Guidance for the Japanese Government that in principle, tests for 14 days or longer should be adopted, but the result from the 13-day test was used for classification on the basis that effects on the lung were observed after the 13 days. [Evidence Data] (1) In a study in which rats were exposed by inhalation to this substance (estimated as a vapor) at 120 ppm (1,000 mg/m3, converted guidance value: 0.14 mg/L) within the range of Category 1 for 13 days, lethargy was observed during exposure, and changes in the lung (discoloration, thickening of the alveoli, and lymphatic reactions in the alveolar area) were observed at necropsy at the end of the exposure period (GESTIS (Accessed Sept. 2018)).	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))
