A composition for controlling malodours comprises bacteria producing one or more enzymes selected from the group of enzymes comprising protease, esterase, cellulase, lipase, amylase, urease, xylanase and mixtures thereof; an olfactory receptor inhibitor; a malodour masking composition adapted to absorb malodours and a fragrance. Preferably, the bacteria comprise one or more strains of Bacillus, whilst the olfactory receptor inhibitor may comprise a mixture of 1-cyclohexyl-1-ethyl-n-butyrate and 1-cyclohexyl-ethanol. The malodour masking composition can comprise a salt or other derivative of ricinoleic acid, wherein the salt may be a zinc salt or sodium salt. A surfactant may also be included in the composition. The surfactant may be a non-ionic surfactant or amphoteric surfactant, such as Polyoxyethylene (6) C9-C11 alcohol or a disodium salt of an alkylamine dicarboxylic acid, such as Caflon (RTM) AA30 respectively. The composition may further comprise a malodour neutralising composition that traps the malodour molecules, such as Odouraze (RTM). Suitably, the composition also includes a thickening agent, such as Carbopol (RTM) Ultrez 21 and a dye. |
