The present application relates to a molded preparation for the application of cosmetic and pharmaceutical active ingredients to the skin and / or the hair, in particular in stick form, as a gel based on a fatty acid salt, d. H., A soap, is present, has a good dimensional stability and has antibacterial activity.

Soap gels have long been known in the art as carriers for topically applied cosmetic and pharmaceutical active ingredients. Usually used as soaps sodium stearate gels in aqueous monohydric C ₁ -C ₄ alcohols and glycols. In recent years, attempts have been made to reduce the content of monohydric C ₁ -C ₄ alcohols or to replace them entirely with glycols and polyols.

Commercially available cosmetic compositions are usually formulated as creams or lotions which are taken from a crucible, a tube, a bottle or a pump dispenser; In addition, there are roll-on preparations, sprays and (compact) powder in the market. For consumers, stick preparations for the application of both decorative and nourishing cosmetics enjoy high popularity. They are handy, transport stable and comfortable to apply. Increasingly, there is a need among consumers for compositions that in addition to the basic function, ie z. As the covering of skin blemishes or matting greasy skin, even more care and treatment effects, eg. As by antibacterial or soothing agents, and at the same time convey a pleasant, fresh feel on the skin.

It was an object of the present application to provide a stable stick composition which is a gel based on a fatty acid salt, i. a soap, is present with improved cosmetic care properties. Another object of the present application was to find active ingredients for cosmetic and dermatological compositions in the form of sticks with particularly high skin compatibility and particular efficiency against bacteria and odors. A further object of the present invention was to find active ingredients for cosmetic compositions which make it possible to meet an increased consumer need for products with reduced content of synthetic organic bactericides.

Surprisingly, it has been found that certain silver- and ruthenium-containing surfaces are suitable for the preparation of antibacterial stick compositions. In addition, these surfaces further increase the performance profile of the compositions.

The silver and ruthenium-containing surfaces used in the context of the present invention are described in the prior art: The International Patent Application WO 2008/046513 A2 describes metallic coatings containing silver and ruthenium and additionally anionic surfactants and vitamins.

The proportion of water in the stick compositions of the invention is 20-60 wt .-%, preferably 25-45 wt .-%, particularly preferably 35-40 wt .-%, most preferably 37-39 wt .-%, each based on the total composition.

As a further essential ingredient, the compositions according to the invention contain at least one particle with a silver-containing surface, which is partially coated or doped with ruthenium.

In the compositions of the invention, the per se known oligodynamic effect of silver surfaces for germ reduction on the field of deodorant and antiperspirant compositions transferred and significantly strengthened. The contact of the silver atoms in the surface with ruthenium atoms, which are either as a proportionate coating on the silver surface or as doping in the silver surface, produces an antibacterial effect which goes far beyond the action of elemental silver or silver compounds in the generic products.

It has been found that silver surfaces which are "disrupted" by ruthenium surfaces have advantages in terms of performance and greater effectiveness against bacteria. In this respect, silver-containing surfaces which are partially covered by ruthenium-containing surfaces are preferred.

For cost reasons, it is preferred according to the invention not to provide the silver surfaces contained in the compositions as particles of silver. Since the antibacterial effect starts from the surface anyway, suitable carrier structures or carrier particles can be coated with silver and the silver coating can subsequently be provided with a ruthenium coating partially covering it.

Suitable carrier materials are all customary ingredients of deodorants and antiperspirants, which are solid under the customary conditions of manufacture, storage and use, for example salts of mineral particles such as silicates or zeolites or particles of glass, plastic, ceramic or other metals.

Preferred compositions according to the invention are characterized in that the particle having a silver-containing surface which is partially coated or doped with ruthenium is selected from silver baffles, silver foils, silver-coated grids, silver-coated foils, silver-coated salts, silver-coated glass particles, silver-coated ceramic particles, silver-coated plastic particles, silver-coated mineral particles or mixtures thereof.

With a view to use in cosmetic compositions, particles incorporated into the composition with a silver-containing coating should not exceed certain sizes in order not to be abrasive or to interfere with the applicability of the composition. Too large particles could also lead to a residue problem. Particles which (including coating) have a maximum diameter of 0.5 mm have proved particularly suitable. The diameter is to be understood as the maximum extent along the spatial direction in which the particle has the greatest extent. For a particle in the form of an orthorhombus, the diameter would be the spatial diagonal.

Preferred compositions according to the invention are characterized in that the particle with a silver-containing surface which is partially coated or doped with ruthenium, a diameter of 1 to 500 .mu.m, preferably from 2.5 to 250 .mu.m, more preferably from 5 to 150 .mu.m, still more preferably from 7.5 to 100 microns and in particular from 10 to 25 microns.

The thickness of the coating is preferably chosen so that no abrasion of the coating is to be feared in the usual manufacturing, storage and application conditions. On the other hand, the thickness should be chosen as small as possible for cost reasons. In the context of the present invention, particular preference has been given to compositions in which the thickness of the silver coating coated or doped with ruthenium is 0.1 to 10 .mu.m, preferably 0.25 to 7.5 .mu.m, more preferably 0.5 to 5 .mu.m and in particular 0.75 to 2.5 microns.

The silver-containing surface used according to the invention, which is partially coated or doped with ruthenium, may contain varying amounts of silver and ruthenium, it being preferred for cost reasons to use silver in excess of ruthenium. For reasons of effectiveness, the silver should preferably be used in excess of 5 million times the amount of ruthenium, preferred compositions according to the invention being characterized in that the weight ratio of silver to ruthenium in the coating is 1: 1 to 1,000,000: 1, preferably 10 : 1 to 500,000: 1, more preferably 100: 1 to 250,000: 1 and especially 1000: 1 to 100,000: 1.

Further inventively preferred compositions contain at least one oil-in-water emulsifier. Preferred oil-in-water emulsifiers have an HLB value of more than 7. Other preferred oil-in-water emulsifiers are nonionic. These are emulsifiers which are generally known to the person skilled in the art, as are described, for example, in US Pat Kirk-Othmer, "Encyclopedia of Chemical Technology", 3rd ed., 1979, Vol. 8, pp. 913-916 , are listed. For ethoxylated products, the HLB value is calculated according to the formula HLB = (100-L): 5, where L is the weight fraction of the lipophilic groups, that is the fatty alkyl or fatty acyl groups, in the ethylene oxide adducts, expressed in weight percent.

In selecting nonionic oil-in-water emulsifiers which are suitable according to the invention, it is particularly preferable to use a mixture of nonionic oil-in-water emulsifiers in order to optimally adjust the properties of the compositions according to the invention, such as drug release or washability. The individual emulsifier components thereby deliver a proportion to the total HLB value or average HLB value of the oil-in-water emulsifier mixture in accordance with their proportion of the total amount of the oil-in-water emulsifiers. However, in another preferred embodiment, the compositions according to the invention, in particular the deodorant or antiperspirant sticks, may also contain only a single oil-in-water emulsifier, preferably with an HLB value in the range from 11-17, particularly preferably 12-15 and most preferably 13-14.

With regard to the glycoside radical, both monoglycosides in which a cyclic sugar radical is glycosidically linked to the fatty alcohol and oligomeric glycosides having a degree of oligomerization of up to about 8, preferably 1-2, are suitable. The degree of oligomerization is a statistical mean, which is based on a homolog distribution typical for such technical products. Products which are obtainable under the trademark Plantacare ^®, comprise a glucosidically bonded C ₈ -C ₁₆ alkyl group to an oligoglucoside whose average degree of oligomerization at 1-2, especially 1.2-1.4, lies.
