Description of key information
Skin irritation / corrosion and eye irritation: Data are waived in accordance with REACH Annex VII, because all compounds are flammable gases at room temperature. In liquid form the mixture may cause burns and frostbite due to extreme cold.
Key value for chemical safety assessment
Additional information
All components of the Reaction Mass of Butane and Butene (Butene, CAS 25167-67-3; Butane, CAS 106-97-8; Isobutane, CAS 75-28-5; 2-Methylpropene, CAS 115-11-7) are flammable gases at room temperature and therefore, the requirement for data on skin irritation / corrosion and eye irritation is waived in accordance with REACH Annex VII. In liquid form the mixture may cause burns and frostbite due to extreme cold.
Justification for classification or non-classification
Since the requirement for data on skin irritation / corrosion and eye irritation is waived in accordance with REACH Annex VII, a classification according to Annex VI of Directive 67/548/EWG or Annex I of Directive 1272/2008 (EU-GHS) is not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
