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	- -	-	-	From a description of LD50 value of >15,480 mg/kg (IUCLID (2000)) and >24,000 mg/kg (HSDB (2003)) in the oral administration test employing rats, it was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Dermal)	Not classified	- -	-	-	From a description of LD50 value of >7,940 mg/kg (IUCLID (2000)) and >13,700 mg/kg (HSDB (2003)) in the dermal administration test employing rabbits, it was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Gases)	Not classified (Not applicable)	- -	-	-	Since it was a solid by the definition of GHS and inhalation in gas was not assumed, it was classified into "Not applicable".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
1	Acute toxicity (Inhalation: Dusts and mists)	Classification not possible	- -	-	-	Saturated vapor pressure level of this substance (150degC)is 3.94 mg/L. Since the measured concentration in initiation temperature 125degC is 4.8 mg/L, and LC0 value is >4.8 mg/L in the 4-hour inhalation exposure test employing rats (IUCLID (2000)), classification cannot be specified when applying the mist standard, and classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
2	Skin corrosion/irritation	Not classified	- -	-	-	Based on the description, "slightly irritating" (IUCLID (2000)) in the Draize test with rabbits and the description, "the rabbit skin made to contact this plasticizing agent did not show irritation nor sensitivity,"(HSDB (2003)), it was classified into "Not classified".	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	Although there is description of "slightly irritating" (IUCLID (2000)) in the Draize test employing rabbits, since data is insufficient, classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Respiratory sensitization	Classification not possible	- -	-	-	Classification is not possible since there is no data.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
4	Skin sensitization	Classification not possible	- -	-	-	Although descriptions of "not sensitizing" (IUCLID (2000)) and that "any irritation or sensitizing properties were not indicated to skin of rabbits contacted to this plasticizer for 24 hours" (HSDB (2003)) were shown in the patch test to 200 persons, classification is not possible because of inadequate data.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
5	Germ cell mutagenicity	Not classified	- -	-	-	There is a description that "there is no evidence of the cytogenetical change at highest dose of 1,5000 mg/kg " in the cytogenetics test employing a rat in IUCLID (2000) (EPA/TSCA, GLP). Since IUCLID (2000) describes "The evidence of division delay was not found by the analysis of the mitotic index," the in vivo mutagenicity test (chromosome aberration test) employing a somatic was judged as negative, and it was classified into "Not classified". For an in vitro mutagenicity test, there are descriptions of "negative" in chromosome aberration test employing CHL/IU cultured cell (OECD TG473, GLP) (Health, Labor and Welfare Ministry reports (Access on November 2008)) and "negative" in the mutagenicity test employing Salmonella typhimurium and bacillus coli (OECD TG471, GLP) (Health, Labor and Welfare Ministry reports (Access on November 2008)).	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
6	Carcinogenicity	Classification not possible	- -	-	-	Since no evaluation by major international evaluation agencies is made and there is no data, classification is not possible.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
7	Reproductive toxicity	Classification not possible	- -	-	-	Although there is a description as follows, "Although the body weight reduction in mother animals was observed at a high dose level (3,000mg/kg), teratogenicity was not observed" (IUCLID (2000)) in the forced oral administration study with rats of 6-15 day pregnancy (EPA/TSCA, GLP), classification is not possible, because the reproductive function related data are not available.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
8	Specific target organ toxicity - Single exposure	Classification not possible	- -	-	-	There is a description of "The weight has slightly decreased at 24,000mg/kg, but after that, returned to normal body weight" in the single oral administration test employing male and female rats (HSDB (2003)). Although the effect has been seen in out of the range of guidance value of Category 2, classification is not possible due to insufficient data.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
9	Specific target organ toxicity - Repeated exposure	Category 2 (liver, thyroid)	Warning	H373	P260 P314 P501	It is written in 28-day oral administration test in rats (Guidelines for 28-Day Repeat Dose Toxicity Testing for Chemicals (Japan), GLP) that there were blood cell cholinesterase low level and alkaline phosphatase low level in females, and browning of liver, centrolobular hypertrophy of hepatocytes, and hypertrophy of thyroid follicular epithelial cells in males and females, and thyroid gland enlargement in males, however, stop of administration brought relief, or recovery (Ministry of Health, Labour and Welfare reports (Access on November 2008)). Since effects on liver and thyroid were found within the scope of the guidance value of Category 2, it was classified into Category 2 (liver and thyroid gland). In addition, IUCLID (2000) doesn't contain effects on the thyroid in 90- day mixed feed administration test in rats (Directive 87/302/EEC, GLP)about products of this substance which contain 4% or less of Triphenyl phosphate.	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
10	Aspiration hazard	Classification not possible	- -	-	-	Classification not possible due to lack of data	FY2008	GHS Classification Guidance by the Japanese Government （Sep, 2008）
