GHS Hazard Classification

Globally Harmonized System classification per ECHA C&L inventory and ILO/WHO International Chemical Safety Cards.

Short-term Exposure Effects
The substance and the vapour in high concentrations are irritating to the eyes, skin and respiratory tract. Exposure to very high concentrations could cause depression of the central nervous system.
Long-term Exposure Effects
The substance defats the skin, which may cause dryness or cracking.
Routes of Exposure
The substance can be absorbed into the body by inhalation of its aerosol or vapour, through the skin and by ingestion.

EU CLP Annex VI Harmonized Classification

Legally binding harmonized classification per Regulation (EC) No 1272/2008 (CLP) Annex VI.
