1 Acute toxicity (Oral) Category 4 Warning H302: Harmful if swallowed P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell.
P264: Wash ... thoroughly after handling.
P270: Do not eat, drink or smoke when using this product.
P330: Rinse mouth.
P501: Dispose of contents/container to ...
Rabbit LDLo: 4000 - 4500mg/kg (PATTY 4th, 1994), rat LD50 value: >3200mg/kg (RTECS, 2005) and mouse LD50 value: 1200mg /kg (RTECS, 2005). Based on the lowest LD50 value of the mouse data, it was classified to category 4.
1 Acute toxicity (Dermal) Not classified - - - - Based on rabbit LD50 value: >86700mg/kg (PATTY 4th, 1994), it was set as the outside of Category.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Not classified - - - - There is description of LC50 (2 hours) value: 36.9mg/L (4-hour equivalent: 26.1mg/L). But death is not observed with 7500 - 10000ppm on mouse but observed with 2-hour exposure to 10000 - 12,500ppm (4-hour equivalent assuming 10000ppm: 28.399mg/L) (ACGIH (7th, 2001) and Industrial Hygiene Society advice state). It was judged that there is no death observed below 28.399mg/L (equivalent of 7082ppm), and it was classified as out of Category by the ppm concentration standard.
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 set as Category 3 from description that the skin was stimulated without concrete case report (ICSC (J) (1997), HSDB (2005), and SITTIG (4th, 2002)), and description that mild irritating was acknowledged in the test applied to the skin of the rabbit although it was exposure for 24 hours (RTECS (2005)).
3 Serious eye damage/eye irritation Category 2B - Warning H320: Causes eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
Based on the description in RTECS (2005) that mild irritant property was acknowledged in the test applied to the eyes of the rabbits, and on the descriptions in ICSC (J) (1997) and SITTIG (4th, 2002) that it stimulated the eyes, we categorized it as Category 2B although there were no concrete case reports.
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 - - - - No data available
6 Carcinogenicity Classification not possible - - - - No data available
7 Reproductive toxicity Classification not possible - - - - No data available
8 Specific target organ toxicity - Single exposure Category 3 (Narcotic effects) Warning H336: May cause drowsiness or dizziness (narcotic effects) P304+P340: IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing.
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P261: Avoid breathing dust/fume/gas/mist/vapours/spray.
P271: Use only outdoors or in a well-ventilated area.
P312: Call a POISON CENTER or doctor/physician if you feel unwell.
P405: Store locked up.
P501: Dispose of contents/container to ...
Because of descriptions in ACGIH (7th, 2001) and Japan Society for Occupational Health recommendation (1993) referring to confirmation of abdominal positions in inhalation exposure tests with mice, and of a description in ACGIH (7th, 2001) referring to that anesthetic actions were confirmed in an inhalation exposure test using rabbits, and of descriptions in ICSC (J) (1997), HSDB (2005), HSFS (2002), and SITTIG (4th, 2002) referring to that central nervous systems were affected. So it was judged that there were anesthetic actions, and determined as Category 3 (anesthetic actions).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - Classification not possible due to lack of data
10 Aspiration hazard Category 1 Danger H304: May be fatal 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 ...
Since it is a hydrocarbon and the dynmic viscosity is about 0.95 mm2/s at 20 degrees C ( viscosity/density = 0.732 (mPas)/0.7694 (g/cm3)), and the dynamic viscosity at 40 degrees C is considered to be less than 20.5 mm2/s, we classified it as Category 1.

ENVIRONMENTAL HAZARDS

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 96-hour LC50=3300microg/L of Crustacea (Brown shrimp) (AQUIRE, 2003).
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=321 (existing chemical safety inspections data)).
