Abstract
The present invention relates to amphiphilic water-soluble alkoxylated polyalkyleneimines having an inner polyethylene oxide block comprising 20 to 50 polyethylene oxide units and an outer polypropylene oxide block comprising 10 to 50 polyethylene oxide units and especially to such alkoxylated polyalkyleneimines wherein the ratio of polyethylene oxide units and polypropylene oxide units is proportionally related to the square root of the number of polyalkyleneimine units present in the backbone. The present invention further relates to the use of these alkoxylated polyalkyleneimines as a soil detachment promoting additive to laundry detergents and cleaning compositions and to laundry detergents and cleaning compositions which comprise these alkoxylated mono- or polyalkyleneimines.
