Description
WO 01/00166 PCT/US00/17638 COSMETIC COMPOSITIONS CONTAINING PANTOTHENIC ACID Technical Field The present invention relates to cosmetic compositions. In particular, the present invention relates to cosmetic compositions for the treatment of skin. Background to the Invention Skin is made up of several layers of cells which coat and protect the keratin and collagen fibrous proteins that form the skeleton of its structure. The outermost of these layers, referred to as the stratum corneum, is known to be composed of 25nm protein bundles surrounded by 8nm thick layers. Anionic surfactants and organic solvents typically penetrate the stratum corneum membrane and, by delipidization (i.e. removal of the lipids from the stratum corneum), destroy its integrity. This destruction of the skin surface topography leads to a rough feel and may eventually permit the surfactant or solvent to interact with the keratin, creating irritation. Many people expose their skin to this type of insult every day. In addition, the skin can be damaged by other factors such as exposure to the sun, exposure to cold air, mechanical abrasion, immersion in water etc. Thus, there exists a need for a way of mitigating or ameliorating this damage. In the past compositions have been formulated that are claimed to help to maintain the stratum corneum at its optimum performance in spite of deleterious interactions which the skin may encounter in washing, work, and recreation. Desirable properties for such compositions are that they have good skin feel, water retention, moisturisation, absorption, and/or rub-in characteristics. Prior art compositions have attempted to deliver these properties by the use of one or more 'skin benefit agents'. For example, panthenol, the alcohol form of pantothenic acid, is known for use in skin care products, e.g. shampoos and skin lotions. It has been reported that panthenol, for example in combination with zinc oxide, provides an acceleration of superficial wound healing (see, H. Weise 1 WO 01/00166 PCT/US00/17638 et al., "Acceleration of Superficial Wound Healing by Panthenol Zinc Oxide", Cosmetics and Toiletries, vol. 103, pp. 79-84, October 1988). There appears to be a direct relationship between the amount of the skin benefit agent and the effectiveness of the composition at delivering benefits to the skin. However, it is also the case that the higher the level of skin benefit agent the higher the risk of the associated negatives. Therefore, to date, it has been necessary to balance the benefits of compositions comprising high levels of the skin benefit agents against the negatives associated with such high levels. Thus, there remains a need for compositions which contain high levels of skin benefit agents, and therefore provide high levels of the associated benefits such as skin feel, skin softness and skin smoothness, but show low levels of the associated negatives such as irritation, stickiness or tackiness. Quaternary ammonium agents are also known for use in cosmetic compositions. See, for example, WO-A-99/27904, WO-A-96/32089, and EP-A-789,076. Also, US-A-5,804,205 which discloses skin care compositions which are claimed to provide a high degree of moisturisation without leaving a "tacky" or "sticky" residue. The compositions contain quaternary ammonium compounds having two alkyl groups of 16-22 carbon atoms, humectant and non-irritating hydrophobic microspheres having an average particle size of less than 50 pm. It is claimed that the hydrophobic polymeric microspheres significantly reduce the "tackiness" associated with high humectant levels. The compositions of US-A 5,804,205 may also contain low levels of emollients such as petrolatum or mineral oil. It has now been unexpectedly found that compositions comprising at least one quaternary ammonium agent and greater than 0.5% of pantothenic acid or pantothenic acid derivative and mixtures thereof provide good skin benefits and protect the skin. These compositions have improved user acceptance and, thus, promote better user compliance with concomitant overall improved skin care benefits. While not wishing to be bound by theory, it is believed that the quaternary ammonium agents of the present invention drive the deposition of the 2 WO 01/00166 PCT/US00/17638 pantothenic acid or pantothenic acid derivative onto the skin. This ensures that the maximum skin benefit is derived from the actives while minimising the negatives such as irritation, tackiness and/or stickiness. Also, the quaternary ammonium agents help reduce the loss of the actives from the skin due to environmental factors such as water or abrasion. Moreover, it is believed that the quaternary ammonium agents themselves deliver skin care benefits, such as good moisturisation, good skin feel, good skin softness. Summary of the Invention According to the present invention there is provided a cosmetic composition comprising: (a) at least one quaternary ammonium agent; and (b) greater than 0.5% of pantothenic acid or pantothenic acid derivative and mixtures thereof. The compositions of the present invention give the benefits associated with pantothenic acid or pantothenic acid derivatives such as wound healing and and skin-protection while reducing the associated negatives such as irritation, tackiness and/or stickiness. Detailed Description of the Invention The compositions of the present invention comprise at least one quaternary ammonium agent and greater than 0.5% of pantothenic acid or pantothenic acid derivative and mixtures thereof. These elements will be described in more detail below. The present compositions can be used for any suitable purpose. In particular, the present compositions are suitable for topical application to the skin. In particular, the skin care compositions can be in the form of creams, lotions, gels, and the like. Preferably the cosmetic compositions herein are in the form of an oil-in-water emulsion of one or more oil phases in an aqueous continuous phase, each oil phase comprising a single oily component or a mixture of oily 3 WO 01/00166 PCT/US00/17638 components in miscible or homogeneous form but said different oil phases containing different materials or combinations of materials from each other. The compositions of the present invention preferably comprise vesicles. Preferably said vesicles comprise quaternary ammonium agent and pantothenic acid or pantothenic acid derivative. As used herein the term "vesicle" means one or more bilayers arranged in a closed, usually spherical geometry, said bilayer comprises quaternary ammonium agent as described hereinbelow. Preferably the compositions of the present invention comprise less than 10%, preferably less than 5%, more preferably less than 3%, even more preferably 0%, by weight, of anionic surfactant.

Formulation Process Preferably the compositions of the present invention are prepared in such a way that the quaternary ammonium compound forms vesicles. It is preferred that said vesicles also comprise humectant. Preferably said vesicles also comprise emollient. Even more preferably said vesicles comprise pantothenic acid or pantothenic acid derivatives. In order to ensure optimal performance characteristics it is preferred that the compositions of the present invention are prepared as follows: (i) all or part of the quaternary ammonium agent is mixed with humectant, pantothenic acid or pantothenic acid derivatives, water soluble skin care actives (where included), and, preferably, polar solvent at a temperature which is higher than the melting point of the quaternary ammonium agent; (ii) optionally, the mixture is vigorously agitated; (iii) In a separate vessel the emulsion is prepared as follows; (iv) The oil phase containing the emollients, the relevant thickener in case the said thickener is oil soluble and any remaining quaternary ammonium agent are mixed together at a temperature which is higher than the melting point of the quaternary ammonium agent; The aqueous phase is prepared separately. The water, the relevant thickener in case the said thickener is water soluble, and any remaining water soluble ingredients are heated to the same temperature as the oil phase. 25 WO 01/00166 PCT/US00/17638 (v) the temperature of the oil and aqueous phases of the emulsion are then approximately equalised and the aqueous phase is combined with the oil phase with agitation. (vi) On production of the emulsion the mixture formed in step (i) is added to the aforementioned emulsion with agitation. Method of Use The cosmetic compositions of the present invention may be used in a conventional manner for the treatment of skin. An effective amount of the composition, typically from about 0.1 grams to about 50 grams, preferably from about 1 gram to about 20 grams, is applied to wet or dry, preferably wet, skin. Application of the composition typically includes working the composition into the skin, generally with the hands and fingers. The composition is then left on the skin or, preferably, the skin is rinsed. The preferred method of treating the skin, therefore, comprises the steps of: (a) applying an effective amount of the cosmetic composition to the skin, (b) rinsing the skin. A preferred aspect of the present invention involves the above method with an application of the composition on dry skin before an application on wet skin. Therefore, a preferred method comprises: (i) applying to dry skin an effective amount of the cosmetic composition; (ii) rinsing the skin under a shower; (iii) further application of said composition; and (iv) further rinsing. Much of the damage to human skin is caused by repeated exposure to surfactant containing compositions during washing routines. It has been found that this damage can be mitigated using the present compositions. Therefore, another preferred method comprises: (i) washing the skin using a composition comprising surfactants; (ii) rinsing the skin; (iii) applying to the wet skin a composition according to the present invention; (iv) rinsing the skin. 26 WO 01/00166 PCT/US00/17638 It has also been found that the present compositions are particularly useful when incorporated as part of a regular routine. Therefore, another preferred method comprises: (i) applying to the skin a composition comprising: (a) at least one quaternary ammonium compound; (b) humectant; and (ii) rinsing the skin; (iii) repeating steps (i) and (ii) within 48 hours. The present compositions can also be useful in mitigating damage caused by exposure of the skin to ultra violet radiation, damage caused by exposure of the skin to water during swimming or similar water based exercise, damage caused by shaving or exfoliation or damage caused by exposure of the skin to water during bathing.
