1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Not classified - - - - The saturated vapor pressure of this product is 88119ppm, and it is thought that the test was done with vapor. Based on rat LCLo >6370ppm (SIDS (2002)), it was classified as out of Category.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - - No data available
2 Skin corrosion/irritation Category 3 - Warning H316: Causes mild skin irritation P332+P313: If skin irritation occurs: Get medical advice/attention. It was classified as Category 3 based on the statement that redness was caused on humans (ICSC (J) (1999)).

Based on the statement (ICSC (J), (1999)) that redness is produced in humans, it was set as Category 2A-2B.
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Classification not possible - - - - No data available
5 Germ cell mutagenicity Classification not possible - - - - Based on the fact that there were no in vivo test results and on the fact that there being no strong positive finding of multiple indices for in vitro tests, we presupposed that we could not categorize it according to the technical guideline.
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Not classified - - - - It was considered as the outside of category based on the statement that detrimental effect was observed against either parents' reproduction potential and neonaltal development and growth in rat (Health, Labor and Welfare Ministry reports (2006)).

P501: Dispose of contents/container to ...
There is a publication that temporary central nerve inhibition is indicated in humans (PATTY (5th, 2001)), a possibility of affecting a central nervous system, and there is cough and lethargica (ICSC (J), (1999)). There is a publication that an animal also has an anesthetic actions (PATTY (5th, 2001)). So it is classified into Category 3 (anesthetic actions). And based on the statement that there is respiratory irritation in humans (ICSC (J) (1999)), it is classified into Category 3 (respiratory irritation).
9 Specific target organ toxicity - Repeated exposure Not classified - - - - In the study which administered a higher doses than the guidance value of Category 2 to the animal, no apparent toxicity action is observed (SIDS (2002), PATTY (5th, 2001)). According to that it is considered as the outside of Category.
10 Aspiration hazard Category 2 Warning H305: May be harmful if swallowed and enters airways P301+P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician.
P331: Do NOT induce vomiting.
P405: Store locked up.
P501: Dispose of contents/container to ...
Category 2 because of "possible to cause chemical pneumonia by misswallowing of the liquid."(ICSC(J), 1999)

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Category 2 - - H401: Toxic to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
It was classified into Category 2 from 48-hour EC50=2.1mg/L of Crustacea (Daphnia magna), and others (MOE eco-toxicity tests of chemicals, 2000).
11 Hazardous to the aquatic environment (Long-term) Category 2 - H411: Toxic to aquatic life with long lasting effects P273: Avoid release to the environment.
P391: Collect spillage.
P501: Dispose of contents/container to ...
Classified into Category 2, since acute toxicity was Category 2 and not rapidly degrading (BOD: 0% (existing chemical safety inspections data)), though less bio-accumulative (BCF=45 (existing chemical safety inspections data)).
