PHYSICAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - - There are no chemical groups associated with explosive properties present in the molecules.
2 Flammable gases (including chemically unstable gases) Not applicable - - - - Liquid (GHS definition)
3 Aerosols Not applicable - - - - Not aerosol products
4 Oxidizing gases Not applicable - - - - Liquid (GHS definition)
5 Gases under pressure Not applicable - - - - Liquid (GHS definition)
6 Flammable liquids Not classified - - - - Since the flash point was 121 degC (C. C.) (CHRIS-Chemical Hazard Response Information System, U.S.DOT/U.S.Coast Guard, 1999), it was classified as out Category.
7 Flammable solids Not applicable - - - - Liquid (GHS definition)
8 Self-reactive substances and mixtures Not applicable - - - - There are no chemical groups associated with explosive or self-reactive properties present in the molecule.
9 Pyrophoric liquids Not classified - - - - The firing points is 121 degC (C. C.) (CHRIS-Chemical Hazard Response Information System, U.S.DOT/U.S.Coast Guard, 1999), and even if it contacts the normal temperature air, it does not ignite spontaneously.
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 metaloids(B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - - Organic compounds containing oxygen chemically bonded only to carbon and hydrogen (but not to other elements).
14 Oxidizing solids Not applicable - - - - Liquid (GHS definition)
15 Organic peroxides Not applicable - - - - Organic compounds containing no -0-0- 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) Category 5 - Warning H303: May be harmful if swallowed P312: Call a POISON CENTER or doctor/physician if you feel unwell. Category 5 based on SPECIES: Rat; ENDPOINT: LD50; VALUE: 3170mg/kg; (IUCLID, 2000), 3478mg/kg; REFERENCE SOURCE: RTECS (1997)
1 Acute toxicity (Dermal) Classification not possible (Category 5 or Not classified) - Warning H313: May be harmful in contact with skin P312: Call a POISON CENTER or doctor/physician if you feel unwell. From rabbit LD50 value >2000mg/kg (IUCLID, 2000) of the dermal administration test, it cannot be classified (Category 5 or outside of Category).
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.
It was set to category 2 from the description that mild irritation (slight;4 hr) is indicated in the rabbit skin or a middle degree stimulus (Moderate; 24 hr) is indicated in vitro test (IUCLID, 2000).
3 Serious eye damage/eye irritation Category 1 Danger H318: Causes serious eye damage P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P310: Immediately call a POISON CENTER or doctor/physician.
It was set as Category 1 from description which causes caustic (Corrosive) to the rabbit eye (IUCLID, 2000).
4 Respiratory sensitization Classification not possible - - - - No data available
4 Skin sensitization Not classified - - - - Since skin sensitization was not observed in the repetitive application on the human skin (218 patients) (IUCLID, 2000), it carried out the outside of Category.
5 Germ cell mutagenicity Classification not possible - - - - It is only a negative report (IUCLID, 2000) of an Ames test, and it cannot be classified because of insufficient data.
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 - - - - No data available.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available
10 Aspiration hazard Classification not possible - - - - No data available

ENVIRONMENTAL HAZARDS

11 Hazardous to the aquatic environment (Acute) Category 3 - - H402: Harmful to aquatic life P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
It was classified into Category 3 from 72-hour ErC50=87mg/L of algae (Selenastrum) (IUCLID, 2000).
11 Hazardous to the aquatic environment (Long-term) Category 3 - - H412: Harmful to aquatic life with long lasting effects P273: Avoid release to the environment.
P501: Dispose of contents/container to ...
Classified into Category 3, since acute toxicity was Category 3 and rapid degradability is unknown, though supposed less bio-accumulative (log Kow=-0.07 (PHYSPROP Database, 2005)).
