Chemical Composition & Hazardous Ingredients
Detailed component analysis, concentration ranges, and hazardous substance identification
Product Type
substanceGeneral Composition
Concentration is nominal. For the exact product composition, please refer to technical specifications. For safety reasons, the acetylene is dissolved in acetone (Flam. Liq. 2, Eye Irrit. 2, STOT SE 3) or dimethylformamide (Flam. Liq. 3, Repr. 1B, Acute Tox. 4, Eye Irrit. 2) in the gas receptacle. Vapour of the solvent is carried away as impurity when the acetylene is extracted from the gas receptacle. The concentration of the solvent vapour in the gas is lower than the concentration limits to change the classification of the acetylene.
Chemical Components & Hazardous Substances
| Chemical Name | CAS Number | Concentration | Hazardous |
