(57) A detergency enhancing polymer is used in a laundry cleaning operation to improve
removal of oily and/or greasy soil from cotton fabrics. This polymer is a homopolymer
or copolymer containing one or more monomer units independently selected from those
of formula (I)
- wherein -A- is selected from groups of formula -R5-, -R5-(CO)-R6-, -R5-(CO)-O-R6,
-R5-O-(CO)-R6-, -R5-(CO)-NH-R6-, -R5-NH-(CO)-R6-, wherein R5 and R6 are independently
absent, or represent C1-3 alkyl groups;
- R1, R2 and R3 are independently selected from hydrogen, C1-3 alkyl, C1-3 alkenyl,
hydroxy-C1-3 alkyl and C5-8 cycloalkyl groups; and
- R4 is selected from groups as defined for A above;
- wherein R3 may also represent a bridge, group with the group R4, said bridging group
being selected from groups as defined for A above; and
- X - is a monovalent anion or an n'th part of an n-valent anion.
