wherein:
R 1 is C 4 -C 30 -alkyl or C 4 -C 30 -alkenyl,
R 2 is C 3 -C 12 -alkylene or—((CR 10 R 11 ) o —CR 4 R 5 —CR 6 R 7 —O) m —(CR 8 R 9 ) n —,
R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 and R 11 are independently of each other selected from hydrogen or C 1 -C 10 -alkyl,
m is an integer from 1 to 100,
n is an integer from 2 to 12, and
o is an integer from 0 to 10.

2. A composition according to claim 1 , wherein
R 1 is C 4 -C 30 -alkyl, and
R 2 is C 3 -C 12 -alkylene.

3. A composition according to claim 1 , wherein
R 1 is C 6 -C 21 -alkyl, and
R 2 is C 3 -C 6 -alkylene.

4. The composition according to claim 1 , wherein
i) R 1 is a mixture of at least two individual substituents, preferably R 1 is a mixture of at least two C 6 -C 21 -alkyl substituents, more preferably of at least two C 8 -C 12 -alkyl substituents, and/or
ii) R 1 is unsubstituted straight-chain or branched C 4 -C 30 -alkyl or C 4 -C 30 -alkenyl, preferably unsubstituted straight-chain or branched C 6 -C 21 -alkyl, more preferably unsubstituted straight-chain or branched C 8 -C 12 -alkyl.

5. The composition according to any claim 1 , wherein
i) R 2 is straight-chain C 3 -C 12 -alkylene, preferably straight-chain C 3 -C 6 -alkylene, or
ii) R 2 is —(CH 2 —CHR 7 —O) m —CH 2 —CHR 9 —,—(CHR 11 ) o —CHR 5 —CHR 7 —O—(CH 2 ) 3 — or —(CH 2 —CH 2 ) p —O—(CH 2 —CH 2 ) r —,
R 5 , R 7 , R 9 and R 11 are independently of each other selected from H or methyl, preferably R 5 , R 7 , R 9 and R 11 are H,
m is an integer from 1 to 10, preferably m is 1,
n is an integer from 2 to 6, preferably n is 2,
o is an integer from 0 to 5, preferably o is 0 or 1,
p is an integer from 1 to 3, preferably p is 1, and
r is an integer from 1 to 3, preferably r is 1.

6. The composition according to claim 1 , wherein the composition comprises a salt of the esteramine according to claim 1 , wherein the salt is formed by at least partial protonation of the amine group by an acid being a protic organic or inorganic acid.

7. A cleaning composition according to claim 1 , wherein the composition comprises a salt of the esteramine according to claim 1 , wherein the salt is formed by at least partial protonation of the amine group by an acid being selected from the group consisting of methanesulfonic acid, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, toluene sulfonic acid, citric acid, lactic acid, C12-C18 fatty acid, alkyl benzene sulfonic acids, alkyl sulphonic acids, alkyl sulfate acids, alkyl ethyoxysulfate acids, alkoxylated or non-alkoxylated copolymers of acrylic acid and maleic acid, and mixtures thereof.

8. A composition according to claim 1 , wherein the esteramine comprises a salt according to Formula (II)

wherein R 3 is C 1 -C 30 -alkyl, C 2 -C 30 -alkylene or unsubstituted or at least monosubstituted aryl and the substituents are independently selected from C 1 -C 30 -alkyl under the proviso that R 3 is not para toluenyl.

9. A composition according to claim 1 , wherein the esteramine comprises a salt according to Formula (II), wherein R 3 is C 1 -C 30 -alkyl or at least monosubstituted aryl and the substituents are independently selected from C 1 -C 30 -alkyl under the proviso that R 3 is not para toluenyl.

10. A composition according to claim 1 , wherein the esteramine comprises a salt according to Formula (II), wherein R 3 is C 6 -C 18 -alkyl or at least monosubstituted phenyl and the substituents are independently selected from C 1 -C 30 -alkyl under the proviso that R 3 is not para toluenyl.

11. The composition according to claim 1 , wherein the esteramine comprises a salt according to Formula (II), wherein
i) R 3 is monosubstituted phenyl and the substituent is in para position and selected from C 8 -C 16 -alkyl, and/or
ii) R 3 is a mixture of at least two individual substituents, preferably of at least two isomers having a number of carbon atoms in the range of 8 to 20, more preferably of 16 to 18.

12. A cleaning composition according to claim 1 , wherein the surfactant system further comprises one or more surfactants selected from cationic surfactants, non-ionic surfactants, amphoteric surfactants, and mixtures thereof.
