Definitions
- the present invention concerns the use of specific topically-applied cosmetic compositions for reducing malodour on clothing.
- WO 2001/07002 A1 discloses a method for deodorizing an object wherein the object is clothes or body.
- JP2 2007/2822799 A2 discloses a water-based deodorant for reducing the smell of sweat and sebum on clothing.
- WO 2018/195613 A1 discloses a method for deodorizing keratinic or textile material.
- WO 2016/096897 A1 discloses a cosmetic method for controlling odours that can be used on the skin and on materials for deodorizing malodourous environments such as shoe soles or clothing.
- WO 2016/090247 A1 discloses a method of applying a cosmetic composition to skin, hair or clothing. Summary of the Invention
- a topically-applied cosmetic composition comprising a zinc organometallic salt or complex and a carrier material for reducing malodour on clothing worn in proximity to the site of topical application of said cosmetic composition.
- a topically-applied cosmetic composition comprising a zinc organometallic salt or complex and a carrier material for making clothing worn in proximity to the site of topical application of said cosmetic composition smell fresher.
- a topically-applied zinc organometallic salt or complex for making clothing worn in proximity to the site of topical application of the non-aluminium deodorant active.
- a topically-applied cosmetic composition comprising a zinc organometallic salt or complex and a carrier material for reducing malodour trapped in clothing worn in proximity to the site of topical application of said cosmetic composition.
- a topically-applied cosmetic composition comprising a zinc organometallic salt or complex and a carrier material for reducing the transfer of malodour to clothing worn in proximity to the site of topical application of said cosmetic composition.
- a topically-applied zinc organometallic salt or complex for reducing the transfer of malodour to clothing worn in proximity to the site of topical application of the zinc organometallic salt or complex.
- the benefits are of particular note when sportswear and/or synthetic clothing is the clothing worn, especially when the clothing comprises lycra®.
- odour transfer and trapping can be of particular relevance.
- a topically-applied cosmetic composition comprising a zinc organometallic salt or complex and a carrier material to reduce malodour on clothing has not been previously disclosed nor suggested in the prior art.
- the topically-applied deodorant composition does not comprise any aluminium-containing antiperspirant active. In particularly preferred embodiments, the topically-applied deodorant composition does not comprise any aluminium-containing material. By avoiding aluminium-containing materials, a more natural means of reducing odour on clothing may often be achieved.
- the topically-applied deodorant composition does not comprise any antiperspirant active.
- the benefits of the invention are particularly unexpected since there is no reduction in perspiration and its possible transfer to clothing worn in proximity to the skin.
- topical application refers to application to the skin of the human body, in particular to the underarm regions of the human body.
- deodorant actives are materials that reduce malodour, typically following topical application to the skin of the human body.
- antiperspirant actives are materials that reduce perspiration on the skin of the human body, typically following topical application.
- a non-aluminium deodorant active is a material that does not comprise aluminium in any form, whether charged, uncharged, complexed or in any other form.

Detailed Description
For all aspects of the invention, the benefits are of particular note when sportswear and/or synthetic clothing is the clothing worn, especially when the clothing comprises lycra®. For such clothing, odour transfer and trapping can be of particular relevance.
To the best of our knowledge, the use of a topically-applied cosmetic composition comprising a zinc organometallic salt or complex and a carrier material to reduce malodour on clothing has not been previously disclosed nor suggested in the prior art.
In preferred embodiments, the topically-applied deodorant composition does not comprise any aluminium-containing antiperspirant active. In particularly preferred embodiments, the topically-applied deodorant composition does not comprise any aluminium-containing material. By avoiding aluminium-containing materials, a more natural means of reducing odour on clothing may often be achieved.
In preferred embodiments, the topically-applied deodorant composition does not comprise any antiperspirant active. In such embodiments, the benefits of the invention are particularly unexpected since there is no reduction in perspiration and its possible transfer to clothing worn in proximity to the skin.
Herein, topical application refers to application to the skin of the human body, in particular to the underarm regions of the human body.
Herein, deodorant actives are materials that reduce malodour, typically following topical application to the skin of the human body.
Herein, antiperspirant actives are materials that reduce perspiration on the skin of the human body, typically following topical application.
Herein, a non-aluminium deodorant active is a material that does not comprise aluminium in any form, whether charged, uncharged, complexed or in any other form.
Herein, “odour” and “malodour” are used interchangeably.
Herein, methods and uses should be understood to be cosmetic methods/uses, i.e. non- therapeutic methods/uses.
Herein, all percentages, parts, and ratios are by weight, unless otherwise indicated.
Herein, references to an amount of a material or materials refer to the total amount of material(s) of the type indicated.
Herein, references to an amount of a material are with reference to the total composition of which it is a part, unless otherwise indicated.
Herein, “application” and “applied” relate to application to the skin of the human body, in particular the underarm regions, unless the context dictates otherwise.
Herein, features expressed as “preferred” with regard to a particular aspect of the invention should be understood to be preferred with regard to each aspect of the invention.
Herein, preferred, particularly preferred and especially preferred features of the invention are particularly preferred when used in combination with other preferred, particularly preferred, and especially preferred features of the invention.
Herein, “ambient conditions” refer to 20°C and 1 atmosphere pressure, unless otherwise indicated.
Herein, the word “comprising” is intended to mean “including” but not necessarily “consisting of’ or “composed of.” In other words, the listed steps or options need not be exhaustive.
Herein, except in the examples or where otherwise explicitly indicated, all numbers in this description and claims indicating amounts of material or conditions of reaction, physical properties of materials and/or use are to be understood as modified by the word “about”.
Herein, numerical ranges expressed in the format "from x to y" are understood to include x and y. When for a specific feature multiple preferred ranges are described in the format "from x to y", it is understood that all ranges combining the different endpoints are also contemplated.
In preferred embodiments, the zinc organometallic salt or complex is an antimicrobial deodorant active. Such deodorant actives are typically antibacterial actives, acting to counter odour-causing bacteria on the skin surface.

Examples
Transfer of odour from the underarm regions of the human body to T-shirts worn by panelists was assessed in the following test. The test was a sequential monadic, fully rotated design with a washout period ahead of each product use.
152 female panelists, aged 18 - 55, were recruited. Each was a regular antiperspirant or deodorant users (at least 4 times per week). Two products (Example 1 and Example 2 as detailed in Table 1) were tested. Both products were given to the panelists unbranded.
In a first stage, the panelists completed a 7-day “wash-out” prior to the test using a commercial bodywash and body-spray supplied to them. On the morning of the next day, the panelists again used the bodywash supplied to them, but then applied one of the test products, Example 1 or Example 2, to each underarm and put on a T-shirt, also supplied to them. They each wore their T-shirt for 24 hours prior to removing it and heat-sealing it into an aluminium pouch using an iron. Following removal of their “24-hour” T-shirt, the panelists did not wash their upper bodies and nor did they apply any further test product. Instead, they put on a second T-shirt supplied to them and wore this for a further 24 hours. Following this period, they each removed their “48-hour” T-shirt and heat-sealed it into an aluminium pouch using an iron.
In a second stage, each panelist completed a 4-day “wash-out” as described for the first stage before repeating the first stage procedure using the other of Example 1 or Example 2 not used by the panelist during the first stage.
76 of the panelists applied Example 1 in the first stage and Example 2 in the second stage and 76 of the panelists applied Example 2 in the first stage and Example 1 in the second stage, thereby eliminating any order of application effect.
The T-shirts used were white polycotton, from Brennards Textiles. The T-shirts were washed with un-fragranced washing powder (Zero Neutral) prior to use. Each participant received four T-shirts: two for each product (Example 1 and Example 2) at each of the two removal time points (24 and 48 hours following application of the test product).
The “24-hour” and “48-hour” T-shirts were returned to a Unilever laboratory where they were refrigerated to reduce any malodour change prior to malodour assessment. The malodour assessment was performed by an expert panel. The T-shirts were removed from their aluminium pouch and allowed to equilibrate to room temperature before being assessed using a 1 - 5 malodour line scale. The T-shirts were evaluated inside out; the left underarm of each shirt being assessed first and the right underarm being assessed second. A 1-minute interval was allowed before assessment of each subsequent T-shirt. Four to six assessors, depending on assessor availability, rated each of the 608 T-shirts. The mean malodour score for each assessment are indicated at the bottom of Table 1.
The malodour scores found in the underarm regions of the T-shirts worn in proximity to the armpit to which Example 1 had been applied were significant the lower after both 24 hours and 48 hours.
