Field of application of the invention

The invention relates to a cosmetic agent in the form of an ointment, paste, cream or the like, which contains hydrophilic and / or lipophilic active ingredients, a fatty phase, an aqueous phase, emulsifiers, preservatives and fragrances.

Characteristic of the known technical solutions

There are numerous such cosmetic creams, ointments or the like, in particular so-called nutritional and moisturizing creams based on either an oil / water emulsion or a water / oil emulsion based. The problem associated with such creams is, however, that the Areas of the skin having different levels of fat and / or moisture need not be supplied according to their specific needs when applying such creams. According to the fat and / or moisture requirement of the skin, when applying such creams, they usually become either skin areas too much or too little fat phase, .Nutrients or moisture and the like supplied »Even a successive application of creams based on the one and then the other emulsion type brings here no remedy

Aim of the invention

The aim of the invention is the provision of kosmetηη ointments, creams or the like, with the help of different skin areas can be supplied simultaneously according to their specific fat, nutrients and / or ifeuehtigkeitsbedarf.

Explanation of the essence of the invention

The invention is based on the task of finding a composition which has the desired effects.

According to the invention, a cosmetic agent in the form of an ointment, cream or the like is provided, which is characterized in that it contains the hydrophilic and / or lipophilic active ingredients, the fatty phase and aqueous phase in the form of a finely disperse mixture of an oil / water emulsifier and Preservative containing oil / water emulsion and a water / oil emulsifier containing water / oil emulsion contains;

24U9 2 8

With the help of the finely disperse mixture of the two emulsion types containing cream can be produced on the skin depending on their moisture on their different areas or depending on skin types a corresponding oil / water or water / oil hydrolipid film.

According to the invention, the particle size of the emulsion is 2 to 50 μm.

The invention further relates to a process for the preparation of a cosmetic agent in the form of an ointment, paste, cream or the like, which is characterized in that from fat phase, aqueous phase, oil / water emulsifier and preservative an oil / water emulsion and from Fat phase, aqueous phase and water / oil emulsifier produces a water / oil emulsion and that intimately stirred the two emulsions with the addition of hydrophilic and / or lipophilic agents under vacuum at a temperature between 20 and 40 ° C and then the resulting finely dispersed Blended with fragrances.

Although it might seem to be approaching in view of the different needs of the skin, simply the two emulsion types for making a cream. to mix, so as to meet the above-mentioned needs of the skin, so this procedure is not readily possible. This is because the two emulsion types could not be stably maintained side by side, but rather, depending on the ingredients used, at least soon after processing, a conversion of one to the other type of emulsion occurs, so that only one type of emulsion is ultimately obtained in the produced one remains.

Now, if the two types of emulsion at temperatures between 20 and 40 ° C, preferably at 30 ° C under vacuum very gently, but nevertheless very intense, combined in a stirred vessel / earth, so that finally a very fine dispersion of the two emulsions whose particle size between 2 and 50 μπι, preferably between 5 and 15 μπι is achieved, then the two types of emulsion remain unchanged side by side in the cream produced. This emulsion system remains at considerable dilution, e.g. with liquid phase, stable. It is believed that the particle size as well as the interaction of the emulsifiers is important for the stability of this emulsion system. It is essential that in the production fdes cosmetic agent according to the invention, the emulsions used are dispersed and not homogenized.

The combination of the two emulsions is preferably carried out under a vacuum of 0.5 torr to 50 torr. The stirring speed, as is well known to those skilled in the art, depends on the agitator used and must be determined in a manner known per se. ;

The oil / water emulsions and the water / oil emulsions can be prepared in a conventional manner using conventional emulsifiers (Kirk Othmer: Encyclopedia of Chemical Technology, 3rd edition, 1979; John Wiley &Sons; New York, etc. VoI 8, Pages 900 to 930 and Dr. Otto-Albrecht Neumüller: Rompps Chemie Lexikon 7th edition, 1973; 'Franck'sche Verlagshandlung Stuttgart, pages 1009 to 1013). The waxes, emulsifiers used for these emulsions

and other additives are the same as those conventionally used in the case of emulsified skincare preparations (Dr. Otto-Albrecht Neumüller: Rompps Chemie Lexikon, 7 · Aufläge 1973, Franck'sche Verlagshandlung Stuttgart, pages 1427 and 1428),

24449 2 8.

An oil / water emulsion used in the cosmetic composition according to the invention can consist of hydrophilic and / or lipophilic active ingredients, fatty phase, oil / water emulsifier, aqueous phase and preservative.

As hydrophilic and / or lipophilic active ingredients moisturizing factors (hydrocomplexes), such as glycerol, polyethylene glycols or amino acid mixtures, Puroba oil (= jojoba oil), vitamins (preferably vitamin A and E) vital complexes (such as placental extracts), enzymes, Herbal extracts (such as Hammamelis extract or chamomile extract) or proteins (such as collagen) are used. Hydrocarbons such as, for example, Vaseline, paraffins or stearin, or waxes such as, for example, beeswax are suitable as the oily phase or as the fatty phase in the oil / water emulsion. Suitable oil / water emulsifiers are, for example, stearyl alcohol, polyoxyethylene stearates (such as, for example, MYRJ) complex emulsifiers

(such as amphoterin) and sorbitan fatty acid esters (such as Span) or carboxyvinyl polymers (such as Carbopol). The aqueous phase may additionally contain buffer substances, such as, for example, the disodium salt of ethylenediamine-N, N, N ', N'-tetraacetic acid and preservatives, such as chlorquinaldol, parabens or benzalkonium chloride.

In the oil / water emulsion, the proportion of the inner emulsion is preferably 30 to 49 wt.%, The particle size of the inner emulsion is preferably between 1μ and 100μ. In the dispersion of both phases, it is comminuted again and is below 50μ in the finished product.

A water / oil emulsion which can be used in the cosmetic according to the invention in turn consists of hydrophilic and / or lipophilic active ingredients, as are also used in the oil / water emulsion, fatty phase, water / oil emulsifier and aqueous phase. As the oily phase or fat phase of the water / oil emulsion, hydrocarbons, e.g. Paraffins and Vaseline, synthetic, vegetable and animal oils or waxes (such as olive oil, peanut oil, fine bone oil, almond oil, lanolin, beeswax or sunflower oil) are used, as an aqueous phase purified demineralized water and as a water / oil emulsifier wool fat ( = Lanolin), fatty alcohols such as cetyl alcohol, myristyl alcohol, stearyl alcohol or ceryl alcohol, fatty acid esters such as beeswax (Cera alba) or wax alcohol esters or mixed esters (such as Dehy-

  (R), muls).

In the water / oil emulsion, the proportion of the inner emulsion is preferably 30 to 49 wt.% ,. the particle size of the inner emulsion is preferably between 1μ and ΙΟΟμ. In the dispersion of both phases, it is comminuted again and is below 50μ in the finished product.
