Definitions

  • the present invention according to a first aspect concerns a malodor counteracting and/or masking composition, which is in particular effective against malodor developed during soaking and/or hand washing laundry.
  • the invention further concerns a method for counteracting or masking malodor, in particular malodor produced during soaking and/or hand washing of laundry.
  • the invention concerns a laundry detergent comprising a malodor counteracting and/or masking composition.
  • Further aspects of the invention concern a method of preparing a malodor counteracting and/or masking composition, a fragrance composition comprising a malodor counteracting and/or masking composition, and a method for soaking and/or hand washing and/or machine washing of laundry.
  • soaking ' and hand washing are very common.
  • 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.
  • 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.
  • 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.
  • composition suitable for counteracting and/or masking malodor developed during soaking and/or hand washing of laundry comprising:
  • R1 a hydrogen atom or a linear or branched, saturated or unsaturated alkanoate, aldehydic, or alkoxy radical having 1-4 carbon atoms,
  • R2 a hydrogen atom or a linear, saturated alkylcarboxylate radical having 1-4 carbon atoms
  • Verdalia A Greenyl methylether
  • the notation/nomenclature used in the CAS database is used for certain substituents/structural units.
  • 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.
  • a method for counteracting or masking malodor produced during soaking and/or hand washing of laundry comprises the following steps:
  • a laundry detergent which comprises a malodor counteracting and/or masking effective amount of a composition as described above with respect to the first aspect of the present invention.
  • Such laundry detergent is of particular use in laundry processes which comprise soaking and/or hand washing of laundry, however, it can also be useful in other types of laundry processes like e.g. machine washing.
  • the laundry detergent preferably is a powder detergent which is water soluble.
  • a method of preparing a malodor counteracting and/or masking composition comprising the step of mixing one, two or more members of the group consisting of:
  • 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
  • a solvent or a dispersion agent and/or other additives such that the total amount of said member(s) of said group is sufficient for counteracting and/or masking a malodor in a process comprising soaking and/or hand washing of laundry.
  • a fragrance composition comprising (a) a sensorically effective amount of a fragrance material and (b) a malodor counteracting and/or masking effective amount of one member or a mixture of two or more members of the group defined above with respect to the first aspect of the present invention, wherein (a) said fragrance and (b) said member or mixture of members are not the same.
  • the fragrance composition of the present invention is particularly useful for providing laundry with a fragrance which is (at least almost) unaffected by malodor normally- produced during soaking and/or hand washing.
  • the malodor counteracting and/or masking substance may or may not contribute to the overall sensoric appearance of the laundry.
  • a method for soaking and/or hand washing and/or machine washing of laundry comprising the following steps:
  • the present invention allows for a significant reduction of adverse malodor when (a) a sample of laundry treated with the malodor counteracting and/or masking composition of the present invention (or a corresponding laundry detergent) is compared with (b) a control laundry treated with a composition not comprising any malodor counteracting and/or masking substances (e.g. pure water or a laundry detergent without malodor counteracting substances).
  • a sample of laundry treated with the malodor counteracting and/or masking composition of the present invention or a corresponding laundry detergent

  • the malodor counteracting and/or masking effect of materials is evaluated according to the following protocol, and a corresponding masking index is determined:
  • 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).
  • 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.
