Abstract

The present invention relates to silica coated containers containing so-called Pickering emulsions.

Description

The The present invention relates to silica coated containers, containing the so-called Pickering emulsions.

you knows especially from the cosmetic field preparations two immiscible phases containing an oily phase and have an aqueous phase, wherein usually the oily phase due to their lower density over the aqueous phase is located. At the time of use obtained by stirring or shaking an emulsion. A preparation with completely separate aqueous and oily phase is then useful if the preparation contains active substances, either only in the aqueous phase or only in the oily one Stable phase can be stored. A preparation from however, two overlapping phases are possible completely homogenize only with great effort, whereas in practice the tendency is usually adjusts that the upper oily sublayer in larger Amount consumed as the aqueous sublayer.

emulsifiers allow or facilitate in this context the even distribution of two or more not miscible phases and prevent their segregation. They are therefore used to stabilize water-lipid mixtures used in the form of emulsions. Emulsifiers set the interfacial tension between the phases down, passing at the interface oil / water interface films training, whereby the irreversible confluence of Droplet is counteracted. It usually arises cloudy emulsions with a droplet size in the micrometer range. As emulsifiers usually surfactants used.

Under A Pickering emulsion is understood to mean emulsions which are emulsifying Components instead of surfactants or optionally in addition to surfactants finely divided powdered solids. The use of these finely divided powdered solids with emulsifying properties has the advantage that on the use of short-chain surfactants with irritative properties can be dispensed with, on the other hand one can by using larger Solid particles produce Pickering emulsions that are optically visible Having ball structures. These optically visible sphere structures also allow the stabilization of lipophilic drugs, the would be unstable in an aqueous environment.

Microparticle finely divided W / O emulsions with oil droplets which are free of surfactants and stabilized only by solids are disclosed in the Laid Open Publication EP 0686391 described. To stabilize spherical polyalkylsilsesquioxane particles are used here, which have a diameter of 100 nm up to 20 microns. In EP 0870495 also finely divided O / W emulsions are described with oil droplets in the micrometer range, in which case in addition to finely divided solids with a diameter of up to 200 nm and surfactants are used as emulsifiers.

In US 3,920,883 and US 4,767,741 On the other hand, surfactant-free droplet-shaped O / W macroemulsions having a particle diameter of the oil droplets in the range from 0.1 millimeters to several centimeters are disclosed in which finely divided solid particles are also used as emulsifier.

Regarding a potential commercial use of these Pickering emulsions it has turned out to be a problem that the Pickering emulsions in the cost, weight and safety aspects provided plastic containers not stably stored but the pearl structure of the Pickering emulsion Disintegrated because the oil phase is the plastic surface better wetted than the aqueous phase.

According to the invention was Now surprisingly found that silica-coated Containers excellent for storage of Pickering emulsions are suitable because the Pickering emulsions are stored in these can, without causing the decomposition of the Pickering emulsion comes.

A first subject of the present invention is therefore an at least partially, preferably in the interior, coated with silica (SiO _x ) container, characterized in that it contains a Pickering emulsion.

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 is suitable for non-compatible In ingredients more effectively and sustainably. Especially with long storage times are thus to achieve decisive advantages in terms of stability and the constant composition of the preparation.

These Macroemulsions are further distinguished by the fact that the Emulsion is not milky or cloudy, but a high Translucency possesses, as the visible and from each other distinguishable spherical particles in the preferred colorless first phase emulsified as clearly distinguishable objects available.

As a further component, the preparation according to the invention may preferably contain a density compensation agent. In the context of the invention, density compensation means are to be understood as meaning all substances which are suitable for varying the relative density of the first and second phases relative to one another. The function of the density compensation agent is either to increase the density of a phase by increasing the mass of the respective phase without practically changing the volume, or to decrease the density of a phase the volume is increased without changing the respective mass decisively. The density compensation agent is selected from the group of substances soluble in the first or second phase as well as their mixtures.

When Example of a density compensation agent that in the second phase Soluble, you can use oils, especially adipates such as dioctyl adipate, myristates such as isopropyl myristate, palmitates, such as Octyl palmitate, stearates such as isopropyl stearate, vitamins such as vitamin A, Vitamin E, Vitamin F, Oils like sunflower oil, Fish oil, pentaerythrityl tetra-2-ethylhexanoate and their Name mixtures or similar products.

As a density compensator, which is soluble in the first phase, you can also have one cosmetic ingredient, e.g. B. a preservative, UV filter fabric, a buffering agent and a shine agent for the complexion as well in general, any water-soluble compound or its Name mixtures suitable for increasing the density of the water vary.

you may also use one or more density compensation means, which soluble in both the first and second phases are.

In a further preferred embodiment of the invention the density of the second phase is greater than that Density of the first phase or the density of the second phase corresponds the density of the first phase. This ensures that that in the form of spherical particles in the first Phase emulsified second phase in the first phase hovers or itself at the bottom settles. A contact of the second phase with the atmospheric oxygen is thus excluded, so in the oil component (2. Phase) dissolved or dispersed sensitive active substances during storage and application effectively before contact with the To be protected against atmospheric oxygen.

According to the invention optionally in addition to the finely divided, powdery solids Surfactants may be included in the Pickering emulsions.

That the addition of surfactants in the preparation of the inventive Pickering emulsions with a diameter of 0.5 to 20 mm possible would be surprising to a person skilled in the art, as that was to be expected by competing micelle formation the disperse phase is split into so small drops that this with the naked eye no longer perceptible or distinguishable are. The inventive formation of a macroscopic Drop structure in the presence of surfactants was thus surprising and unpredictable.

Usable according to the invention Surfactants are preferably selected from the group of anionic, cationic, amphoteric and / or nonionic surfactants or mixtures thereof.

Around to be perceptible, a perfume must be volatile, besides the nature of the functional groups and the structure the molecular weight of the chemical compound also plays an important role plays. So most perfumes have molecular weights up to about 200 Dalton, while molar masses of 300 Daltons and above tend to be constitute an exception. Due to the different volatility of fragrances, the smell of one of several changes Fragrances of composite perfume or fragrance during evaporation, taking the odor impressions in "top note", "heart or middle note" (middle note or body) and "base note" (end note or dry out). Because the smell perception to a large Part also based on the odor intensity, there is the Top note of a perfume or fragrance not only from volatile Compounds, while the base note to the largest Part of less volatile, d. H. adherent fragrances consists. When composing perfumes can more volatile fragrances, for example, to certain Fixative, which prevents it from evaporating too quickly becomes. In the subsequent classification of the fragrances in "lighter volatile "or" adherent "fragrances is about the odor impression and whether the corresponding fragrance is perceived as the head or middle note, nothing said.

In a further preferred embodiment include the Pickering emulsions according to the invention conditioning agents. As examples of conditioning agents are this Context, without, however, being limited to cationic and amphoteric and / or nonionic polymers and / or whose mixtures or copolymers mentioned.

Under Polymers within the meaning of the invention are both natural as well as synthetic polymers.

Under Cationic polymers are understood to mean polymers which are used in the Main and / or side chain have a group which "temporarily" or "permanent" can be cationic. To be "permanently cationic" According to the invention refers to such polymers, the regardless of the pH of the agent, a cationic group exhibit. These are usually polymers that are quaternary Nitrogen atom, for example in the form of an ammonium group. Preferred cationic groups are quaternary ammonium groups. Especially those polymers in which the quaternary ammonium group over a C1-4 hydrocarbon group on one of acrylic acid, Methacrylic acid or derivatives thereof built polymer backbone are bound, have proved to be particularly suitable.

Further Cationic polymers according to the invention are the so-called temporary cationic polymers. These polymers usually contain an amino group which in certain pH values as quaternary ammonium group and thus cationic is present.

These Both groups of polymers have a potentially cationic charge together. Both cationic and amphoteric or zwitterionic Polymers can therefore have their cationic charge density be characterized. The invention Polymers 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 from at least 3 meq / g to 7 meq / g.

One another characteristic feature of the invention Polymers is their molecular weight. Below the molecular weight of the respective polymer is the molecular weight understood by the manufacturer in the corresponding Datasheets measured by its method. For the selection of a suitable polymer has a molecular weight of at least 50,000 g / u as being suitable according to the invention proved. Have polymers with a molecular weight of more than 100,000 g / u proved to be particularly suitable. Polymers with one molecular weight of more than 1000,000 g / u are 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 ^- or -SO ₃ ^- groups, and summarized those polymers containing -COOH or SO ₃ H groups and quaternary ammonium groups.

amphoteric Polymers, like the cationic polymers, are very particular preferred polymers.
