Abstract

Foam-form or foamable cosmetic preparations containing 2-phenylethyl benzoate and the use of 2-phenylethyl benzoate in cosmetic foams.

Description

The The present invention relates to foamy or foamable cosmetic Preparations containing 2-phenylethyl benzoate and one or more UV filter substances from the group of triazine derivatives

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 surfactant 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 63 341-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 foams, 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.

• • Verwendung von 2-Phenylethylbenzoat zur Schaumverstärkung und Schaumstabilisierung selbstschäumender, schaumförmiger, nachschäumender oder schäumbarer kosmetischer Zubereitungen enthaltend ein oder mehrere UV-Filtersubstanzen aus der Gruppe der Triazinderivate.

The task is solved by surprise

• Foam-like or foamable cosmetic preparations containing 2-phenylethyl benzoate and one or more UV filter substances from the group of triazine derivatives, and by the
• Use of 2-phenylethyl benzoate for foam reinforcement and foam stabilization of self-foaming, foam-like, post-foaming or foamable cosmetic preparations containing one or more UV filter substances from the group of the triazine derivatives.

Under "self-foaming", "foamy", "nachschäumend" or "foamable" is in the sense of Understand the present invention that the gas bubbles (arbitrary) distributed in one (or more) liquid phase (s), the preparations are not necessarily macroscopically Look like a foam. Cosmetic preparations according to the present invention (in hereinafter also referred to as foams for the sake of simplicity) can, for. B. macroscopically visible dispersed systems from in liquids represent dispersed gases. The foam character can but also, for example first under a (light) microscope visible. Furthermore are foams according to the present Invention - in particular then, when the gas bubbles too small to be detected under a light microscope - even on recognizable by the strong volume increase of the system.

By For the first time, the invention becomes a rich, compact cream foam ("Mousse") accessible, the over a long storage life as well as an extraordinarily high stability and a Compact appearance distinguishes. Compositions according to the invention are already developing during their production - for example while of stirring or in the homogenization - too fine bubble foams. According to the invention are fine bubbles, rich foams of outstanding cosmetic elegance available. Furthermore, according to the invention are particularly good skin-friendly Preparations available, with valuable ingredients distributed particularly well on the skin can be.

object The invention further relates to the use of 2-phenylethyl benzoate for reducing the bubble size of self-foaming, foamy, after-foaming or foamable cosmetic preparations.

With "foam reinforcement" is beyond meant that stability the foamed Preparations (the "foam stability") compared to otherwise same preparations which no UV filter substances according to the invention significantly improved, d. H. by the use according to the invention a break of the foams delayed in time.

Further is under "foam reinforcement" within the meaning of the present Invention to understand that the cosmetic properties the foams of the invention in comparison to preparations which do not contain UV filter substances according to the invention, be significantly improved: Thus obtained by the use of the invention rich, firm foams ("Foam creams"), which despite their Compactness and richness are easily redistributable and fast move in.

Especially is under "foam reinforcement" within the meaning of the present Invention to understand that the bubble size of the foams of the invention in comparison to preparations which do not contain UV filter substances according to the invention, is smaller. In contrast, the number of bubbles is increased in the same volume.

With "bubbles" are in the sense of present invention, the gas bubbles meant, under "bubble size" is accordingly the diameter of the gas bubbles to understand.

This Effect can be very good from a microscopic foam examination be clarified. The aim of this study is the microscopic Determination of the number and size of bubbles in cosmetic products.

• • Von der zu untersuchenden kosmetischen Zubereitung wird an drei verschiedenen Stellen (z. B. oben, Mitte, unten) aus dem Behälter jeweils eine Probe mittels Spatel entnommen (entsprechend drei Proben pro Zubereitung). (Aerosolschäume werden in ein Reservoir oder auf Zellstoff gesprüht und die Proben aus dem Reservoir gezogen.)
• • Einwaage von 9 mg ± 0,5mg auf Objektträgern
• • Abdeckung der Probe mit einem Abdeckglas
• • Vor der eigentlichen Aufnahme wird auf den Objektträger mit Abdeckglas für 15 sec ein Gewicht von 20 g gelegt.

A microscopic foam examination can be carried out, for example, as follows, at a constant temperature of 21 ° C.:

• • One sample of the cosmetic preparation to be examined is taken from the container at three different locations (eg top, middle, bottom) using a spatula (corresponding to three samples per preparation). (Aerosol foams are sprayed into a reservoir or pulp and samples are drawn from the reservoir.)
• • Weighed 9 mg ± 0.5 mg on slides
• • Cover the sample with a cover glass
• • Before the actual recording, place a weight of 20 g on the slide with cover glass for 15 sec.
• • Subsequently, three images are taken of each sample, with the area under investigation being 6.22 mm × 4.66 mm = 28.11 mm ² . For this, the microscope is set to 125x magnification and the sample is illuminated in transmitted light (digital camera Polaroid DMC and image analysis program KS400).
