Claim:
A method to counteract malodors, which comprises applying to a closed space, or a surface intended to be deodorized or freshened, a malodor counteracting (MOC) composition in an amount sufficient to reduce, mask, eliminate or prevent malodor perception from the closed space or surface, wherein the MOC composition consists of a mixture of at least two ingredients selected from Group (I) compounds, at least one ingredient selected from Group (II) compounds, and at least two ingredients selected from Group (III) compounds, wherein the Groups (I) to (III) compounds are defined as follows: a) Group (I): aldehydes selected from at least two of the following sub-groups: Sub-group a): aldehydes consisting of a linear, saturated or unsaturated, aliphatic C7 chain, optionally substituted with up to six carbon atoms; Sub-group b): aldehydes consisting of a linear, saturated or unsaturated, aliphatic C8 chain, optionally substituted with up to five carbon atoms; Sub-group c): aldehydes consisting of a linear, saturated or unsaturated, aliphatic C9 chain, optionally substituted with up to four carbon atoms; Sub-group d): aldehydes consisting of a linear, saturated or unsaturated, aliphatic C10 chain, optionally substituted with up to three carbon atoms; Sub-group e): aldehydes consisting of a linear, saturated or unsaturated, aliphatic C11 chain, optionally substituted with up to two carbon atoms; or Sub-group f): aldehydes consisting of a linear, saturated or unsaturated, aliphatic C12 chain, optionally substituted with one carbon atom; b) Group (II): ketones of formula R2COR3, wherein R2 is an ethyl or methyl group and R3 is an aliphatic linear or branched, saturated or unsaturated carbon chain containing from 1 to 12 carbon atoms; and c) Group (III): primary alcohols selected from at least two of the following sub-groups: Sub-group g): alcohols consisting of a linear, saturated or unsaturated, aliphatic C6 chain, optionally substituted with up to seven carbon atoms; Sub-group h): alcohols consisting of a linear, saturated or unsaturated, aliphatic C8 chain, optionally substituted with up to five carbon atoms; or Sub-group i): alcohols consisting of a linear, saturated or unsaturated, aliphatic C10 chain, optionally substituted with up to three carbon atoms, wherein the aldehydes of Group (I) are present in a concentration of between 55 and 60% by weight, the ketone of Group (II) is present in a concentration of between 20 and 25% by weight and the primary alcohols of Group (III) are present in a concentration of between 20 and 25% by weight, all concentrations being relative to the total weight of the composition.
