Danger

Combustible liquid (H227)
Toxic if swallowed (H301)
Harmful in contact with skin (H312)
Fatal if inhaled (H330)
Causes skin irritation (H315)
May cause allergic skin reaction (H317)
Causes damage to organs (H370)

Ingredient disclosure

Comments:

Both method and type of cup used to determine the flash point are not available in the consulted scientific litterature. However, the reported value has been estimated to be sufficiently reliable to classify the substance in a hazard category.

Inhalation acute toxicity (H330) classification was established from the lowest tested dose (1,42mg/L/4h). At this dose, all animals died. Therefore this chemical could be classified in a more severe hazard category than the one mentioned above.
