Since the test was not of a technical product, it was excluded as a reference for classification.	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）

Thus, the substance was classified into Category 1.	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）
5	Germ cell mutagenicity	Not classified	- -	-	-	Mouse spot tests, a kind of in vivo mutagenicity test using somatic cell, gave negative results (IUCLID, 2000). In addition, rats that received oral administration of the substance did not show chromosomal aberrations in bone marrow cells (IARC 30, 1983). Based on these results, the substance was classified into the "Not classified" category.	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）

Based on these ratings, the substance was classified into Category 2.	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）
7	Reproductive toxicity	Category 1B	Danger	H360	P308+P313 P201 P202 P280 P405 P501	In oral and dermal applications of this substance to pregnant rats, malformations such as cardiac malformations, diaphragmatic hernias, and hydronephrosis were noted in pups that were born from exposed mothers at doses that did not show toxic effects in maternal animals (PDS 84 (1996)). In addition, hydrocephalus and microphthalmia were seen in progeny of mice that received oral administration of the substance during gestation (IARC 30 (1983)). Also, oral administration of the substance to pregnant rats was associated with increased fetal deaths and lowered postnatal survival rates. These reports demonstrated that clear cases of reproductive toxicity become apparent at doses that do not show maternal toxicity. Thus, the substance was classified into Category 1B.	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）

Based on these reports, the substance was classified into Category 3 (respiratory tract irritation). Regarding its effect on the nervous system, details such as the relationship between the effects and doses were not found. Thus, classification was not carried out for the nervous system.	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）

Based on these reports, the substance was classified into Category 1 (blood system) and Category 2 (nervous system).	FY2007	GHS Classification Manual （10 Feb, 2006）/Technical Guidance Document on the GHS Classification （6 Dec, 2005）
