7 | Flammable solids | Not applicable | - | - | - | "Liquids" according to GHS definition. |
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 classified | - | - | - | It is conceivable that it does not ignite at normal temperatures from an autoignition temperature of 420 degrees C (Sax (11th, 2004)). |
10 | Pyrophoric solids | Not applicable | - | - | - | "Liquids" according to GHS definition. |
11 | Self-heating substances and mixtures | Classification not possible | - | - | - | No established test method suitable for liquid substances. |
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). |

Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|
1 | Acute toxicity (Oral) | Not classified | - | - | - | On the basis of an LD50 value of 2240 mg/kg bw for rats (PATTY (5th, 2001)), it was classified as "Not classified" in JIS classification (corresponding to Category 5 in UN GHS classification). |
1 | Acute toxicity (Dermal) | Classification not possible | - | - | - | Because an LD50 value of > 13800 mg/kg bw for rats (GESTIS (Access on Aug. 2011)), which corresponds to "Not classified", is from List 3 and unknown details, it was classified as "Classification not possible." |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | "Liquids" 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 | Not classified | - | - | - | From an MMAS (equivalent to AOI; the maximal value is 110) of 2.0 as an eye irritation score in a test applied 0.1 mL of undiluted solution of this substance to rabbits eyes, in which conjunctiva redness of grade 1 observed 1 day after application disappeared after 2 days (ECETOC 48 (1998)), it was classified as "Not classified." |
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. |
