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)	Classification not possible	- -	-	-	[Rationale for the Classification] There are no data in rodents including rats. Therefore, classification was not possible due to lack of data. [Reference Data, etc.] (1) LD50 for rabbits: > 3,000 mg/kg (EHC 110 (1990), Environmental Risk Assessment for Chemical Substances Vol.4 (Ministry of the Environment, 2005))	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
1	Acute toxicity (Dermal)	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))

2	Skin corrosion/irritation	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. Besides, there is (1), but the details are unknown. [Reference Data, etc.] (1) It was reported that skin irritation in guinea pigs was mild for this substance, moderate for the o-isomer (CAS RN 78-30-8) and p-isomer (CAS RN 78-32-0), and there was no irritation for an isomer mixture (CAS RN 1330-78-5) (Environmental Risk Assessment for Chemical Substances Vol.4 (Ministry of the Environment, 2005)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	[Rationale for the Classification] Classification not possible due to lack of data. Besides, there is a report in (1), but the details are unknown. [Reference Data, etc.] (1) There is a description that this substance may cause eye irritation if it turns into a vapor under high temperature environment (HSDB (2013)).	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] Classification not possible due to lack of data. [Evidence Data] (1) There is a report that in a patch test on a person (67-year-old woman) who developed dermatitis, a positive reaction was observed with a 0.5% solution of this substance, but no reaction was observed with a 5% solution of the p-isomer (CAS RN 78-32-0) (HSDB (2013), Carlsen L, et al. (1986)).	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] There are no in vivo data. Therefore, classification was not possible due to lack of data. [Evidence Data] (1) As for in vitro, the result of a bacterial reverse mutation test was negative (NTP DB (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] As for carcinogenicity, there are no available reports on humans. There are no classification results by domestic and international organizations, and in experimental animals, there is also no test report using this substance of a high purity. Therefore, it was classified as "Classification not possible" due to lack of data. Besides, in carcinogenicity studies in which an isomer mixture was administered by feeding to rats and mice for 2 years in (1), no evidence of carcinogenicity was observed in either sex in either species. [Reference Data, etc.] (1) In carcinogenicity tests in which as a test substance, an isomer mixture of a purity of 79% (tricresyl phosphate (CAS RN 1330-78-5)) containing 21% of this substance, 4% of the p-isomer and less than 1% of the o-isomer was administered by feeding to rats and mice for 2 years, no evidence of carcinogenicity was observed in either sex in either species (NTP TR433 (1994), Environmental Risk Assessment for Chemical Substances Vol.4 (Ministry of the Environment, 2005)).	FY2018	GHS Classification Guidance for the Japanese Government (FY2013 revised edition (Ver. 1.1))
7	Reproductive toxicity	Classification not possible	- -	-	-	[Rationale for the Classification] Based on (1), isomer mixtures were classified in Category 1B (GHS Classification Result in FY 2008), but there is no test report using this substance of a high purity. Therefore, classification was not possible due to lack of data. [Reference Data, etc.] (1) There is a report that in a two generation test with mice by continuous breeding using an isomer mixture of a purity of 79% (tricresyl phosphate (CAS RN 1330-78-5)) containing 21% of this substance, 4% of the p-isomer, and less than 1% of the o-isomer as a test substance, in the F0 generation, a decrease in the number of births and an effect on the sperms (decreased sperm count and motility, morphological abnormalities), and also in the F1 generation, a decrease in the pregnancy rate, the number of live births and a decrease in sperm motility were observed (Environmental Risk Assessment for Chemical Substances Vol.4 (Ministry of the Environment, 2005)).	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] Based on the data in (1) and (2), although the o-isomer is a neurotoxic substance, as for the m-isomer, which is this substance, human and experimental animal data from which neurotoxicity were suspected, could not be obtained. Other than these, there are no data with which target organs can be identified other than the nervous system. Therefore, it was classified as "Classification not possible" for this hazard class. [Reference Data] (1) As described in Environmental Risk Assessment for Chemical Substances (Ministry of the Environment) for tricresyl phosphate (CAS RN 1330-78-5), it is stated that the neurotoxicity from ingestion of edible oils and occupational exposure is due to o-isomer (Environmental Risk Assessment for Chemical Substances Vol.4 (Ministry of the Environment, 2005)). (2) There is a description that the intensity of toxicity and neurotoxicity in humans is strong in the order of the p-isomer < m-isomer < o-isomer among the 3 isomers, and oral lethal doses for adults are 1-10 g for the o-isomer, while the m-isomer and p-isomer are practically nontoxic and do not cause demyelination of the nerves (PATTY (6th, 2012)).	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] There is no information available for classification on the effects of this substance in humans, including effects on the nervous system. There is no test report using this substance of a high purity also in animals. Therefore, classification was not possible due to lack of data. Besides, neither of (1) nor (2) can be said to be effects of administration of this substance and can be used for the classification. [Reference Data, etc.] (1) There is a report that in a study in which tricresyl phosphate (TCP (CAS RN1330-78-5)) consisting of composition ratio of 60-65% of this substance and 30-35% of the p-isomer as a test substance was administered by gavage to rats for 90 days, hematological changes suggestive of anemia were observed in females within the range of Category 2 (Environmental Risk Assessment for Chemical Substances Vol.4 (Ministry of the Environment, 2005)). (2) There are reports that in studies in which TCP of a purity of 78% consisting of 21% of this substance, 4% of the p-isomer and less than 1% of the o-isomer as a test substance was administered by feeding to rats and mice for 13 weeks and 2 years, changes of the adrenal cortex (cytoplasmic vacuolization, etc.) were observed at doses within the range of Category 2 (NTP TR433 (1994)).

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))
