The present invention relates to compositions comprising water-soluble alkoxylated polyamines with a low melting point. More specifically, the present invention relates to compositions comprising water-soluble alkoxylated polyamines having an inner polyethylene oxide block comprising 5 to 18 polyethylene oxide units, a middle polyalkylene oxide block comprising 1 to 5 polyalkylene oxide units and an outer polyethylene oxide block comprising 2 to 14 polyethylene oxide units.

The present invention relates to compositions comprising water-soluble alkoxylated polyamines.
Alkoxylated polyamines are known and cleaning compositions comprising alkoxylated polyamines are also known.
When the polyamine backbone of an alkoxylated polyamine is modified with polyethylene oxide units, particularly when the polyamine backbone is modified with a total of fourteen or more polyethylene oxide units per nitrogen atom, the polyamine is typically solid at room temperature and, thus, generally requires melting or incorporation into aqueous solution before further processing. Alkoxylated polyamines that are liquid at room temperature would be easier to process and handle.
