## Abstract

The present invention relates to the field of perfumery and more particularly to the field of malodor counteractancy. In particular, it relates to a method for application of malodor counteracting (MOC) compositions capable of neutralizing in an efficient manner, through chemical reactions, malodors of a large variety of origins and which can be encountered in the air, on textiles, bathroom or kitchen surfaces, and the like. The composition may be applied as is or in the form of a perfuming composition or in a consumer product or article containing the compound or perfume composition.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The method of claim 1, wherein the aldehydes of the MOC composition are selected from decanal, octanal, nonanal, 9-undecenal, (+−)-2,6-dimethyl-5-heptenal or (Z) 4 dodecenal.

### Claim 3 (depends on 1)

The method of claim 1, wherein the ketone of the MOC composition is 2 octanone or 2-heptanone.

### Claim 4 (depends on 1)

The method of claim 1, wherein the primary alcohols of the MOC composition are selected from decan-1-ol, hexan-1-ol, octan-1-ol, or (Z)-3-hexen-1-ol.

### Claim 5 (depends on 1)

The method of claim 1, wherein each compound of the MOC composition is characterized by a vapor pressure above 4 Pa.

### Claim 6 (depends on 1)

The method of claim 1, wherein the MOC composition is applied in the form of a deodorant or antiperspirant, an air freshener or a fabric softener or refresher.

### Claim 7 (depends on 1)

The method of claim 1, wherein the MOC composition comprises at least three aldehydes of Group (I) compounds selected from at least three of Sub-groups a) to f).

### Claim 8 (depends on 1)

The method of claim 1, wherein the MOC composition comprises three alcohols of Group (III) selected from Sub-Groups g) to i).

### Claim 9 (depends on 1)

The method of claim 1, wherein the Group I aldehydes of the MOC composition includes a combination of octanal, nonanal and decanal.

### Claim 10 (depends on 1)

The method of claim 1, wherein the Group III alcohols of the MOC composition include a combination of hexanol, octanol and decanol.

### Claim 11 (depends on 1)

The method of claim 1, wherein the MOC composition consists of the combination of at least three aldehydes of Group (I) compounds selected from at least three of Sub-groups a) to f), at least one Group (II) compound, and at least two Group (III) compounds, wherein the aldehydes of Group (I) include a combination of octanal, nonanal and decanal, and wherein the alcohols of Group (III) include a combination of hexanol, octanol and decanol.
