FIELD OF THE INVENTION [0001] This invention concerns the control of female body odours, particularly odours associated with products of the genito-urinary tract, such as menstrual or catamenial fluids, vaginal fluids, urine. The invention relates particularly to a method of counteracting or reducing odours associated in use with an article selected from sanitary towels or napkins and panty liners, i.e. odours associated with products of the female genito-urinary tract, particularly menstrual or catamenial fluids, vaginal fluids and urine. BACKGROUND TO THE INVENTION [0002] EP 0404470A1 and U.S. Pat. No. 5,501,805 concern compositions of fragrance materials that have in themselves a low or imperceptible level of fragrance, i.e. a low odour intensity, yet which can confer deodorant effects in use. Such compositions may be referred to for brevity as "low odour compositions". These prior art documents disclose the use of such low odour compositions in detergent products and personal body underarm deodorant compositions (for combating axillary malodour). [0003] It has now surprisingly been found that such low odour compositions also find use in combating other body odours. SUMMARY OF THE INVENTION [0004] A method of counteracting or reducing odours associated in use with an article selected from sanitary towels or napkins and panty liners, comprising providing in or on the article a composition of fragrance materials having an odour intensity index of less than about 110, the composition comprising at least 5% w/w of at least one musk and at least 5% w/w of at least one salicylate. [0005] The invention also covers use as a material for counteracting or reducing odours associated in use with an article selected from sanitary towels or napkins and panty liners of a composition of fragrance materials having an odour intensity index of less than about 110, the composition comprising at least 5% w/w of at least one musk and at least 5% w/w of at least one salicylate. [0006] A further aspect of the invention provides use of a composition of fragrance materials having an odour intensity index of less than about 110 in an article selected from sanitary towels or napkins and panty liners, for counteracting or reducing odours associated with female bodily fluids, the composition comprising at least 5% w/w of at least one musk and at least 5% w/w of at least one salicylate selected from a sanitary towel or napkin and a panty liner. [0007] The invention also provides an article selected from a sanitary towel or napkin and a panty liner, wherein the article includes a composition of fragrance materials having an odour intensity index of less than about 110, the composition comprising at least 5% w/w of at least one musk and at least 5% w/w of at least one salicylate. [0008] In all aspects of the invention, references to odour intensity index mean a value obtained by the odour intensity index method set out in EP 0404470 (based on a comparison with the odour intensity of a control sample of a 10% solution of benzyl acetate in dipropylene glycol, which corresponds to an index of 100). [0009] It is preferred to use a composition of fragrance materials having an odour intensity index of less than about 105, more preferably less than about 100. [0010] The composition of fragrance materials may optionally have a malodour reduction value of at least about 0.25, possibly at least about 0.5, or an odour reduction value of at least about 0.25, possibly at least about 0.5. References to malodour reduction value mean a value when tested by the procedure set out in EP 0147191; and references to odour reduction value mean a value when tested by the procedure set out in EP 0003172. EP 0404470, EP 0147191 and EP 0003172 are incorporated herein by reference. [0011] It is to be understood that in this specification, expression such as `perfume` and `fragrance` extend to compositions of which the odour intensity may be so low as to be imperceptible in use. [0012] By using a low odour composition, the present invention can enable undesirable body odours to be counteracted or reduced in a discrete manner without providing an overt fragrance that, while possibly pleasant in itself, might also be considered by the user to be undesirable, particularly given the current trend for providing fragrance-free products. [0013] Examples of suitable perfumery materials for incorporation into a composition of fragrance materials for use in the invention (i.e. a low odour composition) are given in EP 0404470 and U.S. Pat. No. 5,501,805. In general, any of a wide range of perfumery materials may be incorporated into the compositions, provided that the basis of selection is such as to provide a deodorant effect, and the odour intensity index of the resulting composition is as defined above. [0014] Extensive directions for the selection of materials in order to provide a deodorant effect are given for example in EP 0147191, EP 0003172, and U.S. Pat. No. 4,304,679, all three documents being incorporated herein by reference. [0015] It is helpful if the bulk of the individual ingredients chosen for the composition also individually possess an odour intensity index less than about 110, preferably less than about 100, or even lower. Small quantities of more intense materials may, however, be tolerated, e.g. for the purpose of adjusting the mild perfume note which may be given by the overall composition. [0016] The composition comprises at least 5% w/w, preferably at least 10% w/w, more preferably at least 20% w/w of at least one musk, based on the total weight of the composition (including any solvents). Where one or more musks are present, either in these or in other amounts, they can usefully be selected from musks such as those listed below: TABLE-US-00001 Trademark or Trivial Name: Generic name: Ambrettolide Cyclohexadecen-7-olide Celestolide (IFF) 4-Acetyl-6-tert-butyl-1,1- dimethylindane Dihydroambrettolide Cyclohexadecanolide Ethylene brassylate cyclo-1,13-ethylenedioxy-tridecan- 1,13-dione Exaltolide (F) Cyclopentadecanolide Exaltone (F) Cyclopentadecanone Habanolide (F) 1-oxa-5(6)-cyclohexadecen-16-one Galaxolide (IFF) 1,3,4,6,7,8-hexahydro-4,6,6,7,8.8- hexamethylcyclopenta-2-benzopyran Moskene (GIV) 1,1,3,3,5-Pentamethyl-4,6- dinitroindane Musk ambrette 2,4-dinitro-3-methyl-6-tert- butylanisole Musk Ketone 4-tert-butyl-3,5-dinitro-2,6- dimethylacetophenone Musk MC4 (SA) Ethylene 1,12-dodecanedioate Musk R1 (Q) 11-Oxahexadecanolide Musk tibetine 2-tert-butyl-1,3-dinitrol-4,5,6- trinitrobenzene Musk xylol 1-tert-butyl-3,5-dimethyl-2,4,6- trinitrobenzene Phantolide (PFW) 5-Acetyl-1,1,2,3,3,6- hexamethylindane Tonalid (PFW) 1,1,2,4,4,7-Hexamethyl-6-acetyl- 1,2,3,4-tetrahydronaphthalene Traseolide 6-acetyl-1-isopropyl-2,3,3,5- tetramethylindane Versalide (PFW) 1,1,4,4-tetramethyl-6-acetyl-7-ethyl- 1,2,3,4-tetrahydronaphthalene Suppliers indicated in brackets above are as follows: F = Firmenich GIV = Givaudan IFF = International Flavours & Fragrances PFW = Polak`s Frutal Works SA = Soda Aromatics Q = Quest International [0017] Preferred musks include cyclohexadecanolide, cyclopentadecanone, ethylene brassylate, ethylene dodecanedioate and musk R1. [0018] The quantity of musk will generally not exceed 70%, more likely not exceed 60% by weight so that other (non-musk) perfume components provide at least 30% more likely at least 40% by weight of the total weight of the perfume composition (including any solvents). [0019] The composition comprises at least 5% w/w, preferably at least 10% w/w of at least one salicylate, preferably salicylates of aliphatic or arylaliphatic alcohols containing at least three carbon atoms notably 3 to 10 carbon atoms. The amount of salicylate is based on the total weight of the composition, including any solvents. Possible salicylates include: [0020] amyl salicylate [0021] isoamyl salicylate [0022] isobutyl salicylate [0023] cis-3-hexenyl salicylate [0024] hexyl salicylate [0025] cyclohexyl salicylate [0026] benzyl salicylate [0027] phenylethyl salicylate [0028] propyl salicylate [0029] isopropyl salicylate [0030] Preferred salicylates include benzyl salicylate, cis-3-hexenyl salicylate, cyclohexyl salicylate, hexyl salicylate and phenylethyl salicylate. [0031] It is also preferred that the composition contains at least 5% w/w, more preferably at least 10% w/w, most preferably at least 20% w/w of other perfume ingredients which are neither musk nor salicylate nor solvent that is odourless or substantially odourless, based on the total weight of the composition.
