Disclosed is a process for preparing an alkoxylated alkyl (ether) amine of formula (I) with peaked distribution using a catalyst with a multiple-charge counterion, wherein said process comprises reacting, in a first step, a primary alkylamine with an alkylene oxide at a temperature of from about 150 to about 190 degrees C in order to yield the first intermediate followed by reacting, in a second step, the intermediate with (m) additional molar equivalents of alkylene oxide in the presence of a catalyst with multiple-charge counterions to yield the desired final alkoxylated alkyl (ether) amine product (I) wherein R is selected from a linear or branched, saturated or nonsaturated alkyl group containing 8 - 22 carbon atoms, or is a group of the formula: R'- O - (A)a - (B)b - (C)c - wherein A, B, X, Y are alkylene oxide groups containing 2 - 4 carbon atoms, C is an alkylene group containing 3 - 4 carbon atoms, R' is selected from a linear or branched, saturated or non-saturated alkyl group containing 8 - 22 carbon atoms and the other variables are as disclosed in the description.
