A composition comprising: (i) an anti-microbial agent; and (ii) an acidic co-polymer of the Formula (1) wherein: [A] is of Formula (9), [B] is of Formula (10), and [C] is of Formula (12) wherein: [X] is of Formula (11), wherein [A], [B] and [C] may occur in any order; T is an optionally substituted substituent; L and G each independently is an optionally substituted linking group; R1, R2 and R3 are each independently H, optionally substituted C1-20-alkyl or optionally substituted C3-20-cycloalkyl; R4 and R5 are each independently H or C1-4-alkyl; q is 15 to 1000; p is 3 to 50; J is an optionally substituted hydrocarbyl, group; F is an acidic substituent; b is 0, 1, or 2; m is 0 to 350; n is 1 to 75; v is 1 to 100; and w is 1 to 4; provided that at least one of R4 and R5 is H and provided that R1, R2, R3, T, L, J and G do not contain a basic group; and wherein the pka value of the acidic substituent F on the monomer from which [C] is derived is less than 5.5. |
