Description of key information

Additional information

This multi-constituent substance is a mixture of molecules with 3 to 4 ethylene oxide 'monomer' units with a methoxy terminal function at one end of the molecule and a hydroxyl function group at the other end. Based on widely available data from multiple handbooks and manufacturers information on the two constituents, which as a whole can be considered reliable, and the information from this category approach, the following physicochemical information can be derived that is considered representative of this substance:
