EC number: 310-288-2 | CAS number: 161907-78-4 A complex mixture of oxygenated hydrocarbons produced by the distillation of residues from the manufacture of ethylene glycol monoethyl ether. It consists predominantly of a mixture of di-, tri-, tetra- and pentaethylene glycol monoethyl ethers having carbon numbers predominantly in the range C6 to C12 and boiling in the range of approximately 200°C to 300°C (392°F to 572°F).

Key value for chemical safety assessment
- Water solubility:
- 1 020 mg/L
- at the temperature of:
- 20 °C
Additional information
There is no data for the UVCB substance itself. However, a number of handbook sources at least one of which is reliable report that the substance 2-(2-(2-ethoxyyethoxy)ethoxy)ethanol, a major component of the UVCB substance, is fully miscible with water as are all other glycol ethers of this type. It seems therefore a reasonable conclusion that the UVCB substance itself will also be fully miscible with water.
