Abstract
The present invention relates to compositions comprising water-soluble alkoxylated polyalkyleneimines with a low melting point. More specifically, the present invention relates to compositions comprising water-soluble alkoxylated polyalkyleneimines having an inner polyethylene oxide block comprising 5 to 18 polyethylene oxide units, a middle polyalkylene oxide block comprising 1 to 5 polyalkylene oxide units and an outer polyethylene oxide block comprising 2 to 14 polyethylene oxide units.
Claims20
A cleaning composition comprising:
- from about 1% to about 70% by weight of a surfactant system, wherein the surfactant system comprises a detersive surfactant selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, zwitterionic surfactants, amphoteric surfactants, ampholytic surfactants, and mixtures thereof;
- and
- from about 0.1% to about 5% by weight of the composition, of an alkoxylated polyalkylenimine of the general formula I
- in which the variables are each defined as follows:
- R represents identical or different, linear or branched C2-C12-alkylene radicals or an
- etheralkyl unit of formula X:
- 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 from about 0 to about 50;
- B represents a continuation of the alkoxylated polyalkylenimine by branching;
- y is from about 0 to about 150, z is greater than 0 and less than or equal to about 150;
- E is an alkylenoxy unit of the formula II
- in which the variables are each defined as follows:
- R1 represents 1,2-propylene;
- R2 represents hydrogen and/or C1-C22-alkyl and/or C7-C22 aralkyl;
- each of m and p independently has a value in the range of from about 5 to about 14;
- n is an integer having a value in the range of from about 1 to about 5;
- and m+p is equal to or greater than about 14.
