Abstract

A novel alkoxylated polyamines obtainable by a process including the steps a) to d) and having amphiphilic properties. According to step a), a polyamine containing up to 10 amine-groups as such is reacted with a first alkylene oxide (AO1) in order to obtain a first intermediate (I1). Said first intermediate (I1) is reacted with a lactone and/or a hydroxy carbon acid in step b) in order to obtain a second intermediate (I2) followed by step c), wherein said second intermediate (I2) is reacted optionally with alkylene oxide in order to obtain a third intermediate (I3). Afterwards, said third intermediate (I3) is reacted in optional step d) with a second alkylene oxide (AO2) in order to obtain the novel alkoxylated polyamines. The alkoxylated polyamines may also be included in cleaning compositions and/or in fabric and home care products, and the compositions or products as such.

Dependent claims

A cleaning composition comprising:

a) an alkoxylated polyamine comprising a structural unit derived from a polyamine according to general formula (I)
in which the variables are each defined as follows:
R represents identical or different,
i) linear or branched C2-C12 alkylene radicals or
ii) an etheralkyl unit of the following formula (III):
in which the variables are each defined as follows:
R10, R11, R12 represent identical or different, linear or branched C2-C6-alkylene radicals and
d is an integer having a value in the range of about 0 to about 50 or
iii) C5-C10 cycloalkylene radicals optionally substituted with at least one C1-C3 alkyl;
y is an integer having a value in the range of about 0 to about 8;
wherein the alkoxylated polyamine comprises at least one residue according to general formula (IIa)
in which the variables are each defined as follows:
R1 represents C2-C22-(1,2-alkylene) radicals;
R2 represents hydrogen and/or C1-C22-alkyl and/or C7-C22-aralkyl;
R3 represents linear or branched C1-C22-alkylene radicals;
R4 represents C2-C22-(1,2-alkylene) radicals;
R5 represents 1,2-ethylene;
m is an integer having a value of at least about 1 and up to about 10;
n is an integer having a value of at least about 1 and up to about 25;
o is an integer having a value of from 0 and up to 25;
p is an integer having a value of at least about 1 and up to about 5;
with the proviso that the sum of n+0+p is at most about 25,
wherein at least about 50 weight percent of the total amount of moieties the residues R1, R4 in the alkoxylated polyamine originates from C3 and/or C4-alkylene oxides,
and—when o is not zero—then R1 and R5 are selected such that the moieties containing R1 and R5 are of different chemical composition and/or different chemical structure such that there are different arrangements of the alkylene oxides if more than one alkylene oxide is selected for R1 and R5 and the selected alkylene oxides are the same for both R1 and R5;
and
b) a surfactant.
