Definitions
- This invention relates to cosmetic compositions for reducing or preventing body malodour.
- cosmetic compositions comprising a highly effective, sub- lethal inhibitor of selected corynebacteria.
- perfumes There are three types of material routinely used to combat body malodour: perfumes, antiperspirants and deodorants.
- Perfumes typically work by simply masking body malodour.
- Antiperspirants work by blocking the sweat glands, thereby reducing perspiration. However, even the best cosmetically acceptable antiperspirants rarely reduce sweat production by more than 50%.
- Typical deodorants work by reducing the population of microorganisms living on the surface of the skin, thereby reducing the extent of sweat biotransformation referred to above.
- Typical deodorants include ethanol and triclosan
- the present invention concerns malodour reduction via the sub-lethal inhibition of certain corynebacteria, as described in WO 00/01356 (Quest International BV) and WO 00/01353 (Unilever) , the latter of which is incorporated herein by reference.
- WO 00/01356 Quest International BV
- WO 00/01353 Unilever
- WO 00/01353 uses the term "corynebacteria A" to mean corynebacteria that are able to catabolise fatty acids; this term is used with the same meaning in the present application.
- Such bacteria contribute strongly to the formation of body malodour, in particular axillary malodour. For many males, malodour formation is largely caused by corynebacteria A.
- the deodorants presently available on the market tend to be insufficiently effective or substantially reduce the numbers of all bacteria on the skin indiscriminately.
- the present invention offers the opportunity to provide cosmetic compositions, which, for many females, will substantially reduce malodour formation while inactivating only a minor portion of the skin microflora. For many males, malodour formation can be substantially reduced or even largely eliminated while inactivating only one subgroup of the skin microflora, the corynebacteria A.
- the specific active ingredient disclosed in the present application is effective at particularly low concentrations .
- DD 29 39 58 (Medezinische Fakultaet [Charite] der Humboldt Universitaet zu Berlin) describes the use of lipoxygenase inhibitors to act biochemically to reduce sweat production or to inhibit, to various degrees, the action of skin bacteria or their enzymes on the decomposition of sweat to form unpleasant-smelling substances.
- a cosmetic composition comprising 4-hydroxy-3- methoxybenzyl alcohol .
- a cosmetic method of obtaining a deodorancy benefit comprising the topical administration of 4-hydroxy-3- methoxybenzyl alcohol .
- the active ingredient utilised in the present invention is capable of inhibiting fatty acid catabolism by corynebacteria A at a concentration below that which would lead to the death of said corynebacteria A.
- the active ingredient leads to a deodorancy benefit without significant harm to the skin's natural microflora.
- the active ingredient is effective at particularly low concentrations, being able to reduce the fatty acid catabolism of corynebacteria A by greater than 50% at a concentration of 0.5 mg/ml or less.
- the aforementioned inhibitory effect may be described as sub-lethal, in that the effect is obtained at a concentration below that which would lead to the death of the corynebacteria A.
- the effect may be further defined as a significant inhibition of fatty acid catabolism, for example greater than 50% inhibition of pentadecanoic acid utilisation, without a concomitant reduction in cell viability ( ⁇ 1 logio CFU/ml reduction) of the corynebacteria
- the active ingredient is able to produce this effect at a concentration of 0.25 mg/ml or less.
- the active ingredient may be employed in any cosmetic composition.
- a particularly useful application is in deodorant compositions, particularly those used on the human body, and especially those used for treatment of underarm and/or foot malodour.
- compositions according to the invention comprise an effective total concentration of active ingredient; that is to say, a concentration sufficient to inhibit the catabolism of fatty acids by corynebacteria A on normal use of the composition.
- Typical concentrations range from 0.001 to 10%, preferably from 0.01 to 5%, and especially from 0.2 to 2% by weight of the composition.
- compositions of the invention do not comprise significant amounts of additional anti-microbial agents that cause lethal inhibition of corynebacteria A. It is desirable that the total concentration of such anti-microbial agents is less than the total concentration of active ingredients according to the invention; indeed, it is preferred that the total concentration of such anti-microbial agents is less than half, and especially less than one tenth, of this amount. Active ingredients that cause lethal inhibition of corynebacteria A may be defined as those causing > 1 logio
- Cosmetic compositions according to the invention may take any of a variety of forms. Typical forms include aerosols, sticks, soft solids, creams, gels, roll-ons, pump sprays, squeeze sprays, and compositions for application to deodorant wipes. All of the above forms are particularly applicable forms of deodorant composition.
