The bucket is then capped and allowed to equilibrate (15 min). The panelists (see below for further information) then evaluate the headspace and the soaked towel for malodor perception. They are provided with a sample of malodor in wash liquor as reference. The results of these evaluations are expressed in terms of yes (malodor perceivable) or no (malodor not perceivable). A test material or finished fragrance is considered to be malodor masking if less than 33% of the panelists are able to perceive the malodor both in the headspace and on the towel.
- the malodor perception is assessed by a panel of 15 to 20 individuals (panelists), who have been screened for their olfactory acuity and are trained in the method of evaluation.

In the course of a laundry process, soaking' and hand washing are very common. During the process perceivable malodors are generated and/or set free through complex interaction between fabrics, dirt (eg. sweat) and wash liquor.
The present invention provides methods and substances for reducing the perception of these malodors which are generated during soaking and hand washing of laundry.
There is a number of documents disclosing related art. US patents 4,304,679, 4,322,308, 4,289,641 and 4,663,068 relate to certain perfume compositions for detergent compositions which exhibit a deodorant action. This deodorant action is achieved through deposition of the perfume composition onto the fabric during the wash. The fabric then has the property of reducing body malodor when the fabric is subsequently worn in contact with the skin.
Further malodor counteracting compositions are disclosed in WO 00/27442, US 4,187,251 and US 4,310,512, according to which a perception of a malodor is decreased while reducing or not contributing to the overall perceived odor level. These malodor counteractant compositions are inter alia meant to be included in cloths deodorants as used for washing machine applications such as in detergent, powders, liquids or fabric softeners.
According to WO 00/1360 unpleasant sulphurous body odors are reduced by treating fabric with laundry products containing specific perfume compositions. These compositions contain at least 15% defined aldehydes and at least 30% of one of five categories of hydroxylic materials, ketones, esthers, esters and nitriles.
EP 483 426 A1 teaches a deodorant composition for controlling malodor from perspiration comprising a thiol heterocyclic compound. The deodorant composition can be applied to fabric through a laundry product.
WO 01/16265 discloses a method of reducing odor on fabrics in a wash or rinse solution. The odor control agent is selected from the group consisting of uncomplexed cyclodextrin, odor blocker, specified aldehydes, flavonoid, metallic
salt, and mixtures thereof. To be effective however, a high amount of cyclodextrin is required.
Thus, although a number of approaches have been made to prevent malodor development during washing of laundry, there is still a need for improved malodor counteracting and/or masking substances .
Correspondingly, according to the first aspect of the invention, there is provided a composition suitable for counteracting and/or masking malodor developed during soaking and/or hand washing of laundry comprising:
a malodor counteracting and/or masking effective amount of one member or a mixture of two or more members of the group consisting of:
- compounds of the formula
with the cyclopentane ring being saturated or unsaturated (as indicated by the dotted line), and with
R1 = a hydrogen atom or a linear or branched, saturated or unsaturated alkanoate, aldehydic, or alkoxy radical having 1-4 carbon atoms,
and, independently thereof,
R2 = a hydrogen atom or a linear, saturated alkylcarboxylate radical having 1-4 carbon atoms
(for these compounds hereinafter also the term "methanoindene derivatives according to the present invention" is used),
Aldehyde C-11 (Undecanal)
Aldehyde C-11 Inter
Aldehyde C-12 Laurie
Ethyl Rosate
Galbanum Oil

Dihydromyrcenol
Ethylvanillin
Florazon
Irisnitrile
Methyl lonone Gamma
Nonalactone Gamma

and mixtures thereof.
The listed members of the group, methanoindene derivates or not, exhibit a surprisingly high malodor counteracting and/or masking effect as demonstrated in malodor reduction tests described in detail below.
In particular preferred is the use of a malodor counteracting and/or masking effective amount of one member or a mixture of two or more members of the group consisting of the following methanoindene derivatives according to the present invention:
Greenyl Acetate
tricyclo[5.2.1.0.(2,6)]dec-3-en-8-yl acetate CAS-No 5413-60-5 tricyclo[5.2.1.0.(2,6)]dec-4-en-8-yl acetate CAS-No 2500-83-6 Mixture: 54830-99-8

Fruitate
ethyl(1S,2R,6R,7R)-tricyclo[5.2.1.0.(2,6)]dec-4-ene-2-carboxylate CAS-No 80657-64-3
Herein, the notation/nomenclature used in the CAS database is used for certain substituents/structural units. E.g., with respect to Fleuroxene H2C=CH-CH2-O-D1 indicates that the H2C=CH-CH2-O- unit is attached at an unknown position to the ring system. Further information can be derived from the nomenclature name and/or the CAS-No stated.
Although certain methanoindene derivatives have already been mentioned in documents relating to malodor counteractant compositions the related art provided no teaching that a composition could be formulated which comprises a malodor counteracting and/or masking effective amount of said methanoindene derivatives.
EP 1 113 105 A2 (International Flavors & Fragrances Inc.) concerns a human sweat malodor counteractant composition and process for using same. It discloses certain fragrances comprising hexahydro-4,7-methanoindene-5-yl acetate, hexahydro-4,7-methanoindene-6-yl acetate and/or hexahydro-4,7- methanoinden-5-yl propionate besides a number of other organoleptically effective substances. However, EP 1 113 105 A2 comprises no teaching that said methanoindene derivatives are effective on its own and thus could be incorporated into a malodor or masking composition in an (individually) malodor counteracting and/or masking effective amount. Accordingly, said methanoindene derivatives are not characterized as essential ingredients of the malodor maskant compositions disclosed in EP 1 113 105 A2.
WO 99/57233 discloses a perfume composition comprising at least 5% (by weight of the perfume composition) of a so-called "class 4"-substance which can be ethyl tricyclo[5.2.1.0(2,6)]decane-2-carboxylate (Fruitate). Besides said class 4 component at least 17% of a class 3 and at least 20% of a class 6 component are present. Thus, WO 99/57233 does not disclose a malodor counteracting and/or masking composition comprising a malodor counteracting and/or masking effective amount of a methanoindene derivative as stated above. To the contrary, according to WO 99/57233 only a combination of components chosen from class 3 plus class 4 plus class 6 is useful.
Amongst the substances listed above the following non-methanoindene compounds exhibit a particularly pronounced malodor counteracting and/or masking effect (masking index = 5, see below): Aldehyde C-11 (Undecanal), Aldehyde C-11 Inter, Aldehyde C-12 Laurie, Ethyl Rosate, Galbanum Oil, Hivertal, Methyl Cresol Para, Methylacetophenone, Patchouli Oil, Undecavertol.

The invention is further illustrated by means of the following examples without being limited thereto.
Example 1 :
The malodor counteracting and/or masking effect of materials is evaluated according to the following protocol, and a corresponding masking index is determined:
1. An unperfumed water-soluble laundry detergent powder (composition see table 1 below) is dosed (pre-treated) with 0.1% of test material (comprising one or more members of said malodor counteracting and/or masking substances) or 0.2% to 0.5% of finished fragrance (comprising one or more members of said malodor counteracting and/or masking substances and further fragrance for perfuming the laundry detergent and/or laundry).
2. In a 3 I bucket, at 25° C a specified amount of synthetic sweat malodor (see table 2) is mixed with 1 I of wash liquor and 5 g of the pre-treated laundry detergent powder according to point 1.
3. A white cotton towel (30 x 30 cm, prewashed with unperfumed laundry powder) is added to the resultant mixture according to point 2, and the mixture containing the towel is stirred for 1 min in the bucket.
4. The bucket is then capped and allowed to equilibrate (15 min). The panelists (see below for further information) then evaluate the headspace and the soaked towel for malodor perception. They are provided with a sample of malodor in wash liquor as reference. The results of these evaluations are expressed in terms of yes (malodor perceivable) or no (malodor not perceivable). A test material or finished fragrance is considered to be malodor masking if less than 33% of the panelists are able to perceive the malodor both in the headspace and on the towel.
The malodor perception is assessed by a panel of 15 to 20 individuals (panelists), who have been screened for their olfactory acuity and are trained in the method of evaluation.
5. For determining the masking index of the materials tested different concentrations of malodor were used according to table 3.
6. The evaluation results for a number of materials tested is listed in table 4.
