摘要: The present invention relates to novel modified alkoxylated polyalkylene imines or modified alkoxylated polyamines obtainable by a process comprising the steps a) to d). According to step a), a polyalkylene imine or a polyamine as such is reacted with a first alkylene oxide (AO1) in order to obtain a first intermediate (11). Said first intermediate (11) is reacted with at least one first lactone (LA1) and/or at least one first hydroxy carbon acid (HA1) in step b) in order to obtain a second intermediate (I2), followed by step c), wherein said second intermediate (I2) is reacted with at least one second alkylene oxide (AO2) in order to obtain a third intermediate (I3). Afterwards, said third intermediate (I3) is reacted with at least one second lactone (LA2) and/or at least one second hydroxy carbon acid (HA2) in order to obtain the novel modified alkoxylated polyalkylene imines or modified alkoxylated polyamines according to the present invention. The present invention further relates to a process as such for preparing such modified alkoxylated polyalkylene imines or modified alkoxylated polyamines as well as to the use of such compounds within, for example, cleaning compositions and/or in fabric and home care products. Furthermore, the present invention also relates to those compositions or products as such.
