The present invention relates to a method for inhibiting or reducing the growth of a microbial biofilm on a surface, characterised in that the method comprises a step of contacting the biofilm-forming microorganism with a compound according to Formula (1), or a salt or solvate thereof (Formula 1) wherein "ORG" is an organic moiety having from 2 to 20 carbon atoms; "v" is 1, 2, 3, 4, or 5; "L" provides a covalent link to "ORG" and is selected from O, NH, or is a direct bond from the carbonyl group to "ORG"; "n" is 0 or 1; and R1, R2 and R3 are independently selected from H, OH and OCH3 provided that at least one of R1, R2 and R3 is OH.
