PHYSICAL HAZARDS

Hazard class Classification Symbol

Hazard statement Precautionary statement Rationale for the classification
1 Explosives Not applicable - - - There are no chemical groups associated with explosive properties present in the molecule.
2 Flammable gases (including chemically unstable gases) Not applicable - - - "Solids" according to GHS definition.
3 Aerosols Not applicable - - - Not an aerosol product.
4 Oxidizing gases Not applicable - - - "Solids" according to GHS definition.
5 Gases under pressure Not applicable - - - "Solids" according to GHS definition.
6 Flammable liquids Not applicable - - - "Solids" according to GHS definition.
7 Flammable solids Classification not possible - - - No data.
8 Self-reactive substances and mixtures Not applicable - - - Containing neither chemical groups related to explosibility nor those related to self-reactivity.
9 Pyrophoric liquids Not applicable - - - "Solids" according to GHS definition.
10 Pyrophoric solids Classification not possible - - - No data.
11 Self-heating substances and mixtures Classification not possible - - - No established test method suitable for solid substances with a melting point of 140 degrees C or lower.
12 Substances and mixtures which, in contact with water, emit flammable gases Not applicable - - - Not containing metals or semimetals (B, Si, P, Ge, As, Se, Sn, Sb, Te, Bi, Po, At).
13 Oxidizing liquids Not applicable - - - "Solids" according to GHS definition.
14 Oxidizing solids Not applicable - - - An organic compound that contains oxygen which is not chemically bonded to elements other than carbon or hydrogen.
15 Organic peroxides Not applicable - - - An organic compound that does not contain -O-O- structure.
16 Corrosive to metals Classification not possible - - - A solid with a melting point of 55 degrees C or lower has no data.

HEALTH HAZARDS

Hazard statement Precautionary statement Rationale for the classification
1 Acute toxicity (Oral) Category 4

Warning
H302
P301+P312
P264
P270
P330
P501
Both of two LD50 values for rats correspond to Category 4 (1280 and 1350 mg/kg bw) (JECFA 1146 (2008)).
1 Acute toxicity (Dermal) Classification not possible - - - Lack of data.
Besides, a reported LD50 value of > 5000 mg/kg for rabbits (RTECS (1997)) is from List 3 data and unknown details.
1 Acute toxicity (Inhalation: Gases) Not applicable - - - "Solids" according to GHS definition.
1 Acute toxicity (Inhalation: Vapours) Classification not possible - - - No data.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible - - - No data.
2 Skin corrosion/irritation Classification not possible - - - No data.
3 Serious eye damage/eye irritation Classification not possible - - - No data.
4 Respiratory sensitization Classification not possible - - - No data.
4 Skin sensitization Classification not possible - - - No data.
5 Germ cell mutagenicity Classification not possible - - - No data.
6 Carcinogenicity Classification not possible - - - No data.
7 Reproductive toxicity Classification not possible - - - No data.
8 Specific target organ toxicity - Single exposure Classification not possible - - - No data.
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - A 16-week diet administration test given 10000 mg/kg (diet) to rats and a 28-week diet administration test given 1000 mg/kg (diet) to rats reported that effects on test substance administration were not observed in both tests, and NOELs were 10000 mg/kg (diet) (1000 mg/kg bw/day) and 1000 mg/kg (diet) (100 mg/kg bw/day) respectively (JECFA 1146 (2008)).
Therefore, both NOELs above upper limit (100 mg/kg/day) of values in Guidance in two repeated administration tests by oral route correspond to "Not classified", but the classification in specific target organ toxicity (repeated exposure) was classified as "Classification not possible" because effects on other routes (dermal, inhalation) are unknown due to no data.
10 Aspiration hazard Classification not possible - - - No data.

12 Hazardous to the ozone layer Classification not possible - - - This substance is not listed in Annexes to the Montreal Protocol.
