The present invention relates to water-soluble alkoxylated polyalkyleneimines having an inner block of polyethylene oxide comprising 5 to 18 polyethylene oxide units, a middle block of polyalkylene oxide comprising 1 to 5 polyalkylene oxide units and an outer block of polyethylene oxide comprising 2 to 14 polyethylene oxide units. The middle block is formed from polypropylene oxide units, polybutylene oxide units and/or polypentene oxide units. In addition, the present invention relates to water-soluble alkoxylated polyamines. La presente invención se refiere a polialquileniminas alcoxiladas solubles en agua que tiene un bloque interno de óxido de polietileno que comprende 5 a 18 unidades de óxido de polietileno, un bloque medio de óxido de polialquileno que comprende 1 a 5 unidades de óxido de polialquileno y un bloque externo de óxido de polietileno que comprende 2 a 14 unidades de óxido de polietileno. El bloque medio se forma a partir de unidades de óxido de polipropileno, unidades de óxido de polibutileno y/o unidades de óxido de polipenteno. Además, la presente invención se refiere a poliaminas alcoxiladas solubles en agua.
