Abstract

Foam-form or foamable cosmetic preparations containing one or more organic micropigments.

Description

The The present invention relates to foamy or foamable cosmetic Preparations containing organic micropigments.

Foams or foamy Preparations belong to disperse systems.

The By far the most important and best known disperse system are emulsions Emulsions are two- or multi-phase systems of two or three more in each other not or only slightly soluble liquids. The liquids (pure or as solutions) lie in an emulsion in a more or less fine distribution which generally has only limited stability.

Foams are Structures made of gas-filled, spherical or polyhedron-shaped Cells caused by liquid, semi-liquid, highly viscous or fixed cell ridges. The cell bridges, connected via so-called nodal points, form a coherent one Framework. Between the cell bridges, the foam lamellae (closed-cell Foam). If the foam lamellae are destroyed or flow At the end of foaming back into the cell webs, one obtains an open-celled Foam. Also foams are thermodynamically unstable, since by reducing the surface surface energy can be won. The stability and thus the existence of a Foam is thus dependent on how far it is possible to prevent its self-destruction.

cosmetic foams are usually dispersed systems of liquids and gases, the liquid the dispersant and the gas are the dispersed substance. foams from low-viscosity liquids become temporary by surface-active Stabilized substances (surfactants, foam stabilizers). Such tenside foams because of their big ones inner surface a strong adsorption capacity, which exploited for example in cleaning and washing operations becomes. Accordingly, find cosmetic foams especially in the fields cleaning, such as shaving cream, and hair care Use.

to Generation of foam gas is blown into suitable liquids, or Foaming is achieved by vigorous beating, shaking, splashing or stirring the liquid in the gas atmosphere in question, provided that the fluids suitable surfactants or other surfactants (so-called Foaming agents) which, in addition to interfacial activity, also have some film-forming ability.

cosmetic foams have opposite Other cosmetic preparations have the advantage of being a fine one Allow distribution of active ingredients on the skin. However, they are cosmetic foams usually only by using special surfactants, which in addition often not tolerated by the skin are to reach.

One Disadvantage of the prior art is that such foams only are little stable, which is why they usually collapse within about 24 hours. A request to However, cosmetic preparations is that this one possible Years of stability have. This problem is generally taken into account by that the consumer the actual foam only at the application with the help of a suitable spraying system itself, for which, for example, spray cans can be used, in which a liquefied Compressed gas serves as a propellant gas. When opening the pressure valve escapes the propellant-liquid mixture through a fine nozzle, the propellant evaporates leaving a foam.

Also foaming Cosmetic preparations are known per se. They are initially in a flowable form from an aerosol container applied to the skin and develop after a short delay first there under the influence of the contained Nachschäummittels the actual Foam, for example a shaving cream. Post-foaming preparations are often in special embodiments like frothing Shaving gels or the like.

Of the The prior art also knows cosmetic preparations, which already foamed in the production and thereby in itself one enough high stability show up in ordinary Wrapped, stored and put on the market (see for example DE-100 63 340-A1, DE-100 63341-A1 and DE-100 63 342-A1).

One Disadvantage of the preparations of the prior art, however often the quality of the foam, d. H. the foam is soft, coarse-bubble and after removal from the container only a little stable. Also foamable Cosmetic emulsions (so-called "aerosol foams") can be broken down the prior art without the use of special surfactants not formulate or produce technically. This applies in particular for systems, based on classic emulsifiers. According to the state of the art develop such systems with the addition of propellant exclusively aqueous humid mousses, which break quickly after application.

task Thus, the present invention was to enrich the state of the art and cosmetic self-foaming and / or foamy Preparations available to provide that do not have the disadvantages of the prior art.

cosmetic mousses, which are used in the field of UV light protection, have the Disadvantage, not to be particularly waterproof and while bathing quickly release from the skin again. Cosmetic sunscreen products are predominantly on the beach or swimming pool applied by consumers. The changing bath of sunbathing and water bathing belongs has always been one of the favorite leisure activities of the people.

It was therefore another object of the present invention, a especially waterproof, foamed or foamable develop cosmetic UV sunscreen formulation.

Lots Cosmetic sunscreen products have some stickiness which is usually too unwanted when used on the beach Sand deposits on the skin leads. This phenomenon occurs especially in waterproof UV light protection preparations on.

task The present invention was therefore, sand-repellent, foamable or foamed cosmetic To develop sunscreen preparations.

It represents a fundamental Problem foamed or foamable cosmetic preparations that it is extremely difficult particulate components to be incorporated in storage and temperature stable. In particular, larger quantities on particulate Fabrics as they are for Sunscreens based on pigmentary filters are required, to ensure adequate UV protection, are up to date the technology hardly produce.

The Advantages of micropigments as UV filter substance in cosmetic Preparations are mainly due to the fact that the pigments in the Unlike soluble / liquid organic Sunscreen filters are physically and chemically very stable. They do not tend to decompose even with strong UV radiation or to photoreactions. Due to the fact that it is The pigments are solids, there is no risk of excessive penetration the filter in the skin. The occurrence of allergic reactions is excluded.

task It was therefore the object of the present invention to overcome the disadvantages of the prior art eliminate the technique and stable cosmetic sunscreen preparations with high SPF based on foams too develop. The formulations should be used in your application at the Skin over a longer one Application period stable absorption spectrum with a balanced Have UV-A / UV-B absorption balance.
