1	Acute toxicity (Oral)	Not classified	- -	-	-	A LD50 value of >2000 mg/kg for rats (PATTY (5th, 2001)) corresponds to "Not classified" in JIS Classification (correspond to Category 5 or "Not classified" in GHS classification).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Dermal)	Classification not possible	- -	-	-	Classification not possible due to lack of data. As relevant information, LD50 values are >5000 mg/kg for rabbits and >5000 mg/kg for rats (RTECS, 2008).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

1	Acute toxicity (Inhalation: Vapours)	Classification not possible	- -	-	-	No data available.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
1	Acute toxicity (Inhalation: Dusts and mists)	Not classified	- -	-	-	A LC50 (4h) value of >5.14 mg/L for rats (PATTY (5th, 2001)) corresponds to "Not classified". Since the saturated vapour pressure concentration for the substance was 3.20 mg/L and the test was considered to be conducted for mists, the classification criteria for dust and mist was adopted.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
2	Skin corrosion/irritation	Classification not possible	- -	-	-	Classification not possible due to lack of data. As relevant information, there is a result of "moderate irritation" after application to the skin of rabbits (RTECS (2005)).	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）
3	Serious eye damage/eye irritation	Classification not possible	- -	-	-	There is a report that complaints of irritation of the conjunctiva were not confirmed by examination (ACGIH (7th, 2001)). Animal test data are not available. Based on these information, classification was not possible due to lack of data.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

12	Hazardous to the ozone layer	Classification not possible	- -	-	-	This substance is not listed in Annexes to the Montreal Protocol.	FY2009	GHS Classification Guidance by the Japanese Government （March, 2009）

NOTE:

GHS Classification Result by the Japanese Government is intended to provide a reference for preparing a GHS label or SDS for users. To include the same classification result in a label or SDS for Japan is NOT mandatory.
Users can cite or copy this classification result when preparing a GHS label or SDS. Please be aware, however, that the responsibility for a label or SDS prepared by citing or copying this classification result lies with users.
This GHS classification was conducted based on the information sources and the guidance for classification and judgement which are described in the GHS Classification Guidance for the Japanese Government etc. Using other literature, test results etc. as evidence and including different content from this classification result in a label or SDS are allowed.
Hazard statement and precautionary statement will show by hovering the mouse cursor over a code in the column of "Hazard statement" and "Precautionary statement," respectively. In the excel file, both the codes and statements are provided.
A blank or "-" in the column of "Classification" denotes that a classification for the hazard class was not conducted in the year.
An asterisk “*” in the column of “Classification” denotes that “Not classified (or No applicable)” and/or “Classification not possible” is applicable. Details are described in the column of “Rationale for the classification”. If no English translation is available for “Rationale for the classification,” please refer to the Japanese version of the results.
