Claims14
A fabric and home care product comprising cationic soil release polymer and a lipase enzyme, where the cationic soil release polymer is obtainable by radical copolymerization of:
- at least one monomer of formula (I), in which n is a number in range of from 3 to 120, preferably for a number in the range of from 5 to 50, most preferred for a number in the range of from 7 to 46
- with at least one monomer of formula (II), in which A− is an anion, preferably selected from fluoride, chloride, bromide, iodide, sulfate, hydrogensulfate, alkylsulfate, and mixture thereof
- wherein the lipase enzyme is a variant of SEQ ID NO:1 comprising:
- (a) substitution T231R;
- (b) substitution N233R and/or N233C;
- and
- (c) at least three further substitutions selected from ElC, D27R, N33Q, G38A, F51V, G91Q, D96E, K98L, K98I, D111A, G163K, H198S, E210Q, Y220F, D254S, 1255A, and P256T,
- wherein the positions correspond to the positions of SEQ ID NO:1 and wherein the lipase variant has at least 90% but less than 100% sequence identity to the polypeptide having the amino acid sequence of SEQ ID NO:1 and wherein the variant has lipase activity.
