P501: Dispose of contents/container to ... 		Since its flash point reported 46 degC (closed-cup) (Lange (16th, 2005)) is >= 23 degC and <= 60 degC, the substance corresponds to Category 3. In addition, it is rated as Class 3 PGIII (UN2271) by the UNRTDG.
7 Flammable solids Not applicable - - - - Liquid (GHS definition)
8 Self-reactive substances and mixtures Not applicable - - - - There are no chemical groups present in the molecule associated with explosive or self-reactive properties.
9 Pyrophoric liquids Not classified - - - - Since its auto ignition point is 330 degC (GESTIS (Access on June. 2010)), it is considered that the substance does not ignite at room temperature.
10 Pyrophoric solids Not applicable - - - - Liquid (GHS definition)
11 Self-heating substances and mixtures Classification not possible - - - - Test methods applicable to liquid substances are not available.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - - The chemical structure of the substance does not contain metals or metalloids (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - The substance is an organic compound containing oxygen which is chemically bonded only to carbon or hydrogen.
14 Oxidizing solids Not applicable - - - - Liquid (GHS definition)
15 Organic peroxides Not applicable - - - - Organic compounds containing no bivalent -O-O- structure.
16 Corrosive to metals Classification not possible - - - - No data available.

HEALTH HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity （Oral） Not classified - - - - Based on the rat LD50 value of > 5000 mg/kg (PATTY, 5th (2001)), the substance was classified as "Not classified".
1 Acute toxicity （Dermal） Not classified - - - - Based on the rat LD50 value of > 5000 mg/kg (PATTY, 5th (2001)), the substance was classified as "Not classified".
1 Acute toxicity （Inhalation: Gases） Not applicable - - - - Liquid (GHS definition)
1 Acute toxicity （Inhalation: Vapours） Classification not possible - - - - No data available.
1 Acute toxicity （Inhalation: Dusts and mists） Classification not possible - - - - No data available.
2 Skin corrosion/irritation Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment （see ... on this label）.
P362: Take off contaminated clothing and wash before reuse. 		The substance was classified as Category 2 based on the documented case of "moderate irritation" resulted from rabbit test under an occlusive condition by a wrap with the undiluted substance (PATTY, 5th (2001)).
3 Serious eye damage/eye irritation Classification not possible - - - - No data available.
4 Respiratory sensitization Classification not possible - - - - No data available.
4 Skin sensitization Not classified - - - - In the maximization test in humans, using 2% formulation in petrolatum caused no skin sensitization in 25 volunteers (PATTY, 5th (2001)), and in the modified Draize test using guinea pig, the substance caused no sensitization reactions (PATTY, 5th (2001)). Since both were the data from the "List 1" information source designated in the GHS classification guidance for the Japanese government, the substance was classified as "Not classified".
5 Germ cell mutagenicity Classification not possible - - - - The classification was not possible due to lack of in vivo test data. As relevant information, as for in vitro studies, negative results in the HPRT gene mutation test using Chinese hamster V79 cells and micronucleus test were reported (KemI-Riskline (2006)).
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - No data available.
8 Specific target organ toxicity - Single exposure Classification not possible - - - - As a precaution of clinical signs through an exposure, CNS depression was described in high concentrations (HSDB (2008)). However, since no concrete data were given, the substance was classified as "Classification not possible".
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - The substance is liquid and has a coefficient of kinematic viscosity of 0.97 mm2/s calculated from the coefficient of viscosity of 0.8 mPa*s at 20 degrees centigrade (GESTIS (Access on Jun. 2010)). Because it is not a hydrocarbon but a ketone, the substance was classified as "Classification not possible".
