Phosphate-free detergent composition comprising:
- (A) at least one additive according to general formula (I)
- R1—CO—NH—CH2CH2—O—(AO)x—CH2CH2—NH—CO—R2 (I)
- wherein
- R1, R2 are the same or different and selected from C5-C21-alkyl and C6-C20-alkenyl,
- x is in the range of from 5 to 150, and
- AO is selected from identical or different alkylene oxides, selected from —CH2—CH2—O, —(CH2)3—O, —(CH2)4—O, —CH2CH(CH3)—O, —CH(CH3)—CH2—O—, and —CH2CH(n-C3H7)—O,
- wherein said additive (A) has a melting point in the range of from 40 to 60° C.
