Description

PARTICLE AND SUSTAINABLE EMULSION

The present invention relates to a biphasic preparation comprising at least one surfactant, at least one finely divided, pulverulent solid, and water or a hydrophilic organic solvent or any aqueous or anhydrous mixture as the first phase and at least one fatty substance as the second phase, wherein the second phase in the form of spherical particles having particle diameters of at least 0.5 mm is emulsified in the first phase.

There are known preparations of two immiscible phases which have an oily phase and an aqueous phase with one phase above the other. At the time of use, an emulsion is obtained by stirring or shaking. However, a preparation of two overlaid phases can be completely homogenized only at great expense. As a rule, in the practical application, there is a tendency that the upper oily part layer is consumed in a larger amount than the aqueous part layer.

In this context, emulsifiers enable or facilitate the uniform distribution of two or more immiscible phases and at the same time prevent their segregation. They are therefore used to stabilize water-lipid mixtures in the form of emulsions. Emulsifiers reduce interfacial tension between phases by forming interfacial films at the oil / water interface, thereby counteracting the irreversible flow of droplets. As a rule cloudy emulsions with a droplet size in the micrometer range are formed

U.S. Patent 3,920,883 to Yamada et al. (SHISEIDO) describes an alternative concept for the stabilization of emulsions. The liquid composition disclosed therein contains (1) an oily phase, (2) an aqueous phase, (3) an organic liquid which is miscible with the aqueous but not the oily phase, and (4) finely divided Liquids (1), (2) and (3) insoluble solid particles, which particles are adsorbed at the interface of (1) and (2). The result is a drop-shaped macroemulsion of the oily phase in the aqueous phase, wherein the particle diameter of the oil drops ranges from 0.1 mm to several centimeters. The solid particles have an emulsion-stabilizing effect, since they attach to the droplets of the disperse phase and form a mechanical barrier, so to speak, which prevents the coalescence, ie the confluence of the droplets. such Preparations are known per se and are generally referred to as Pickering emulsions.

U.S. Patent 4,767,741 to Komor et al. (AVON PRODUCTS) contains the technical teaching to provide a two-phase cosmetic liquid composition similar to that of SHISEIDO, except that the immiscible solid particles are formed by an in situ precipitation.

The published patent application EP 0686391 describes emulsions of the water-in-oil type, which are free of surface-active substances and are only stabilized by solids. To stabilize spherical polyalkylsilsesquioxane particles are used here, which have a diameter of 100 nm up to 20 microns. These emulsions can also be referred to as Pickering emulsions according to the above

All these papers have in common that they contain no or no significant amounts of surface-active compounds, so that these compositions no cleansing effect is attributed. Rather, oil-containing cosmetic preparations are described which should form stable emulsions without the addition of surface-active substances.

The published patent application EP 0870495 contains the teaching for providing an emulsion-based cosmetic cleanser. The described liquid composition contains (1) one or more oil components, (2) water, (3) one or more surfactants, and (4) micronized inorganic pigments having an average particle size of less than 200 nm having an amphiphilic character and adsorbed at the interface of (1) and (2). Thus, the preparation is suitable to cause by the surfactants, both a cleaning as well as by the oil components and a nourishing effect. Due to the nanometer-scale particle diameter of the micronized, inorganic pigments, it can be assumed that the preparation is in the form of a milky, finely divided emulsion in which the disperse phase forms droplets so small that they are imperceptible to the naked eye. The fine distribution of the emulsion leads to a very large contact surface between the oil component and the water, which is why sensitive, dissolved or dispersed in the oil component active substances can not be effectively protected from contact with the atmospheric oxygen during storage and application. The milky character of the emulsion is next to one A lack of aesthetic impression also responsible for the fact that no optical differentiation of the phases is possible, so visually no relevant statements about the overall state and the overall composition of the emulsion can be made.

Accordingly, the object of the present invention is to provide a preparation for the treatment and / or cleaning of surfaces or of the skin, in particular of the human skin, which has a cleansing and nourishing effect with high transparency, and also its ingredients are protected from decomposition processes due to external influences over a long storage period.

Surprisingly, it has now been found that a preparation comprising at least two immiscible phases, wherein a) contains a first phase of water, a hydrophilic organic solvent or water in combination with at least one hydrophilic organic solvent or a mixture of different anhydrous hydrophilic organic solvents, b) a second phase contains at least one fatty substance and this second phase is present in the form of optically highly visible and distinguishable spherical particles having a particle diameter of at least 0.5 mm and c) the preparation comprises at least one surfactant and at least one finely divided, pulverulent solid .

has both a cleansing and nourishing effect, provides an effective protection against external influences during storage of sensitive ingredients and is characterized by a high light transmission.

The particle diameter of the optically highly visible and distinguishable spherical particles according to the invention is at least 0.5 mm, preferably 1 to 20 mm, more preferably 2 to 10 mm and more preferably 3 to 8 mm and can easily be determined by a person skilled in the art with the aid of suitable visual, imaging and / or microscopic methods.

For the purposes of the invention, the particle diameter of the spherically visible particles, which are clearly visible and distinguishable from each other, is the average particle diameter. This can be determined by visual, imaging and / or microscopic methods, by a statistically relevant Amount of spherical particles of diameter is determined. The mean particle diameter is then the quotient of the sum of the individual particle diameters and the number of particles.

The formation according to the invention of an emulsion in the form of optically highly visible and distinguishable spherical particles is surprising insofar as the person skilled in the art is satisfied by the addition of surface-active substances, such as e.g. of surfactants would expect competing micelle formation to break up the disperse phase into small droplets that are imperceptible to the naked eye. The inventive formation of a macroscopic droplet structure in the presence of surfactants is thus surprising and unpredictable. The finely divided, pulverulent solid has an emulsion-stabilizing effect, as a result of which the preparation according to the invention can be used for various tasks.

An object of the present invention is therefore the aforementioned preparation.

Another object of the present invention is the use of the inventive preparation for the treatment and / or cleaning of surfaces, in particular of wood, glass, plastic and / or metal surfaces and / or the use of the preparations according to the invention for cosmetic and / or dermatological Treatment and / or cleansing of the skin, in particular of human skin.

According to the invention, the term "skin" generally refers to the skin itself, the mucous membrane and the skin appendages, insofar as they comprise living cells, in particular hair follicles, hair roots, hair bulbs, the anterior epithelium of the nail bed (lectorulus) as well as sebaceous glands and sweat glands.

The present invention particularly relates to the use of the preparation according to the invention for the treatment of sensitive or dry skin, for the treatment of mature skin and / or for the treatment of stressed, in particular UV-stressed, skin.

Likewise provided by the present invention is the use of the preparation according to the invention for the prevention of sensitive or dry skin and / or for the prevention of skin reddening and skin irritations. The present invention furthermore relates to the use of the preparation according to the invention for the care, conditioning and maintenance of the natural lipid coat of creatine fibers.

Likewise provided by the present invention is a process for the treatment of keratinic fibers in which the preparation according to the invention is applied to the keratinic fiber and is rinsed out again after an exposure time of 5 seconds to 45 minutes.

In a preferred embodiment of the invention, the preparation according to the invention is a washing and cleansing lotions, a skin care agent and / or skin protection agent or a hair conditioner.

The invention accordingly also provides a cosmetic and / or pharmaceutical composition which contains the preparation according to the invention as at least one component.

With the formation of optically highly visible and distinguishable spherical particles having a particle diameter of at least 0.5 mm, a significant reduction of the contact area between the first and second phase is achieved in comparison to finely dispersed emulsions due to the larger particle diameter. This achieves an encapsulation effect that makes it possible to separate non-compatible ingredients more effectively and more sustainably. Especially with long storage times are thus to achieve decisive advantages in terms of stability and the constant composition of the preparation.

The preparation according to the invention is further distinguished by the fact that the emulsion formed is not milky or turbid, but has a high light transmission, since the visible and distinguishable spherical particles are emulsified in the preferably colorless first phase as clearly distinguishable objects. This offers the advantage that, for example, by the use of pigment particles of the preparation a special aesthetic effect can be awarded with a high optical brilliance.

In addition, it is possible to convert the preparation according to the invention by mere shaking by hand before use in virtually homogeneous mixtures. In a According to a preferred embodiment of the invention, the second phase emulsified in the form of spherical particles in the first phase after homogenization within a period of 1 to 100 minutes forms the original emulsion having a particle diameter of 0.5 to 20 mm.

Suitable cationic surfactants in the compositions according to the invention are all cationic surfactants suitable for use on the human body or on technical surfaces. Cationic surfactants are distinguished in cosmetic application areas in that, like amphoteric and zwitterionic surfactants, they contribute to a significantly improved cosmetic appearance of the skin and hair. The cationic charge ensures a good bond to the rather negatively charged surfaces, especially of damaged hair or stressed skin. On the long fat residues of these molecular structures, in turn, more hydrophobically structured active ingredients can accumulate. As a result, an overall increased deposition of care substances on the surface of skin and hair is effected. For example, the hair is easier to comb, easier to style both in the dry and in the wet state and shows more shine and a pleasant grip.

Cationic surfactants are generally derived from ammonium ions and have a structure (NR ¹ R ² R ³ R ⁴ ) ^* with a correspondingly negatively charged counterion. Such cationic ammonium compounds are well known to those skilled in the art. Further cationic surfactants are, for example, the esterquats or the imidazolium compounds.

In a further preferred embodiment, the preparations according to the invention contain conditioning agents. As examples of conditioning agents, this connection may be mentioned, but is not limited thereto, to cationic and amphoteric and / or nonionic polymers and / or mixtures thereof or copolymers.

For the purposes of the invention, polymers are understood to mean both natural and synthetic polymers.

Cationic polymers are to be understood as meaning polymers which have a group in the main and / or side chain which may be "temporary" or "permanent" cationic. According to the invention, "permanently cationic" refers to those polymers which have a cationic group, irrespective of the pH of the agent. These are usually polymers containing a quaternary nitrogen atom, for example in the form of an ammonium group. Preferred cationic groups are quaternary ammonium groups. In particular those polymers in which the quaternary ammonium group via a C1-4 hydrocarbon group to one of acrylic acid, methacrylic acid or their Derivatives constructed polymer backbone have been found to be particularly suitable.

Further cationic polymers according to the invention are the so-called "temporary cationic" polymers, which usually contain an amino group which, at certain pH values, is present as a quaternary ammonium group and thus cationically.

These two groups of polymers share a potentially cationic charge. Both cationic and amphoteric or zwitterionic polymers can therefore be characterized by their cationic charge density. The polymers of the invention are characterized by a charge density of at least 1 to 7 meq / g. A charge density of at least 2 to 7 meq / g is preferred. Particularly preferred is a charge density of at least equal to 3meq / g to 7 meq / g.

Another characteristic feature of the polymers according to the invention is their molecular weight. The molecular weight of the particular polymer is understood to mean the molecular weight which the manufacturer indicates in the corresponding data sheets by its method. For the selection of a suitable polymer, a molecular weight of at least 50,000 g / u has proven to be suitable according to the invention. Polymers with a molecular weight of more than 100,000 g / u have proven to be particularly suitable. Polymers with a molecular weight of more than 1000,000 g / u are very particularly suitable.

Furthermore, amphoteric polymers can be used as polymers. The term amphoteric polymers includes both those polymers which contain in the molecule both free amino groups and free -COOH or SO ₃ H groups and are capable of forming internal salts, as well as zwitterionic polymers which in the molecule have quaternary ammonium groups and -COO contain ^" - or -SO ₃ ^" groups, and summarizes those polymers containing -COOH or SO ₃ H groups and quaternary ammonium groups.

Amphoteric polymers, like the cationic polymers, are most preferred polymers.
