The present invention relates to cosmetic and dermatological preparations, in particular those of the water-in-oil type, to processes for their preparation and to their use for cosmetic and medical purposes.
Human skin, as the largest human organ, performs many vital functions. With an average of about 2 m<sup>2</sup> Surface in adults plays a prominent role as a protective and sensory organ. The task of this organ is to mediate and ward off mechanical, thermal, actinic, chemical and biological stimuli. In addition, it plays an important role as regulatory and target organ in human metabolism.
Cosmetic skincare is primarily understood to strengthen or restore the natural function of the skin as a barrier against environmental influences (eg dirt, chemicals, microorganisms) and against the loss of endogenous substances (eg water, natural fats, electrolytes) and their horny layer to assist in the event of damage occurring in their natural regeneration capacity.
If the barrier properties of the skin are disturbed, increased absorption of toxic or allergenic substances or infestation of microorganisms and, as a consequence, toxic or allergic skin reactions may occur.
The aim of skin care is also to compensate for the daily loss of fat and water loss of the skin. This is especially important when the natural regeneration capacity is insufficient. In addition, skin care products to protect against environmental influences, especially from the sun and wind, and delay the aging of the skin.
Medical topical compositions typically contain one or more drugs in effective concentration. For the sake of simplicity, reference is made to the clear distinction between cosmetic and medical use and corresponding products to the statutory provisions of the Federal Republic of Germany (eg Cosmetics Regulation, Food and Medicines Act).
Emulsions are generally understood to mean heterogeneous systems which consist of two liquids that are immiscible or only slightly miscible with one another, which are usually referred to as phases. In an emulsion, one of the two liquids is dispersed in the form of very fine droplets in the other liquid.
If the two liquids are water and oil and oil droplets are finely distributed in water, then it is an oil-in-water emulsion (O / W emulsion, eg milk). The basic character of a Q / W emulsion is characterized by the water. A water-in-oil emulsion (W / O emulsion, eg butter) is the reverse principle, with the basic character being determined by the oil.
Of course, a variety of ways are known in the art to formulate stable W / O preparations for cosmetic or dermatological use, for example in the form of creams and ointments spreadable in the range of room to skin temperature, or as lotions and milk, the are more fluid in this temperature range.
An object of the present invention was to provide preparations which can be formulated with a high or very high content of water-soluble and / or water-miscible substances without impairing the galenic quality or other properties of the preparations.

If vitamin A or vitamin A derivatives, or carotenes or derivatives thereof, are the antioxidant (s), it is advantageous if their respective concentrations are within the range of 0.001-10% by weight, based on the total weight of the formulation, of to choose.
It is of course known to the person skilled in the art that cosmetic preparations are generally not conceivable without the usual hoof and additives. The cosmetic and dermatological preparations according to the invention can accordingly also contain cosmetic adjuvants, as commonly used in such preparations, for example, bodying agent, stabilizers, fillers, Preservatives, perfumes, Substances for preventing foaming, dyes, pigments have the coloring effect, Thickeners, surfactants, emulsifiers, softening, moisturizing and / or moisturizing substances, anti-inflammatory substances, additional active ingredients such as vitamins or proteins, Light stabilizers, insect repellents, bactericides, virucidal, Water, salts antimicrobial, proteolytic or keratolytic substances, Medicines or other common ingredients of a cosmetic or dermatological formulation such as alcohols, polyols polymers Foam stabilizers, organic solvents or electrolytes.

There is no need to mention that in cosmetics only physiologically acceptable electrolytes should be used. Particularly preferred are potassium chloride, common salt, magnesium sulfate, zinc sulfate and mixtures thereof.
Mutatis mutandis have corresponding requirements for the formulation of medical preparations.
The W / O emulsions according to the invention can serve as a basis for cosmetic or dermatological formulations. These may be composed as usual and, for example, for the treatment and care of the skin and / or hair, as a lip care product, as a Deoprodukt and as make-up or Make-up removal product in decorative cosmetics or serve as a sunscreen preparation. For use, the cosmetic and dermatological preparations according to the invention are applied to the skin and / or the hair in a sufficient amount in the manner customary for cosmetics or dermatological agents.
Accordingly, cosmetic or topical dermatological compositions according to the present invention, depending on their structure, for example, be used as skin protection cream, cleansing milk, sunscreen lotion, nutrient cream, day cream or night cream, etc. It is possible and advantageous, the compositions of the invention as a basis for pharmaceutical To use formulations.
The low-viscosity cosmetic or dermatological compositions according to the invention can be present, for example, as preparations which can be sprayed from aerosol containers, squeeze bottles or by a pump device or in the form of a liquid composition which can be applied by means of roll-on devices, but also in the form of an emulsion which can be applied from normal bottles and containers.
Suitable propellants for sprayable from aerosol containers cosmetic or dermatological preparations in the context of the present invention, the usual known volatile, liquefied propellants, such as hydrocarbons (propane, butane, isobutane) are suitable, which can be used alone or in mixture with each other. Also, compressed air is advantageous to use.
Of course, those skilled in the art will recognize that there are inherently nontoxic propellants which would be useful in the practice of the present invention in the form of aerosol preparations, but which should be avoided due to adverse environmental effects or other concomitant conditions, especially fluorocarbons and chlorofluorocarbons (US Pat. CFC).
Also favorable are those cosmetic and dermatological preparations which are in the form of a sunscreen. In addition to the active compound combinations according to the invention, these preferably additionally contain at least one UV-A filter substance and / or at least one UV-B filter substance and / or at least one inorganic pigment.
However, it is also advantageous in the context of the present inventions to prepare such cosmetic and dermatological preparations whose main purpose is not the protection from sunlight, but which nevertheless contain a content of UV protective substances.

Also, UV protectants, as well as antioxidants and, if desired, preservatives, provide effective protection of the preparations themselves against spoilage.
Advantageously, compositions of the invention may also contain substances that absorb UV radiation in the UVB range, the total amount of the filter substances, for example 0.1 wt .-% to 30 wt .-%, preferably 0.5 to 10 wt .-%, in particular 1.0 to 6.0 wt .-%, based on the total weight of the preparations to cosmetic preparations for To provide the hair or protect the skin from the full range of ultraviolet radiation. They can also serve as a sunscreen for hair or skin.
If the emulsions according to the invention contain UVB filter substances, these may be oil-soluble or water-soluble. Oil-soluble UVB filters which are advantageous according to the invention are, for example:<ul id="ul0002" list-style="dash" compact="compact"><li>3-benzylidene camphor derivatives, preferably 3- (4-methylbenzylidene) camphor, 3-benzylidene camphor;</li><li>4-aminobenzoic acid derivatives, preferably 4- (dimethylamino) -benzoic acid (2-ethylhexyl) ester, 4- (dimethylamino) benzoic acid amyl ester;</li><li>Esters of cinnamic acid, preferably 4-methoxycinnamic acid (2-ethylhexyl) ester, 4-methoxycinnamic acid isopentyl ester;</li><li>Esters of salicylic acid, preferably 2-ethylhexyl salicylate, 4-isopropylbenzyl salicylate, homomenthyl salicylate,</li><li>Derivatives of benzophenone, preferably 2-hydroxy-4-methoxybenzophenone, 2-hydroxy-4-methoxy-4'-methylbenzophenone, 2,2'-dihydroxy-4-methoxybenzophenone;</li><li>Esters of benzalmalonic acid, preferably di (2-ethylhexyl) 4-methoxybenzalmalonate,</li><li>Derivatives of 1,3,5-triazine, preferably 2,4,6-trianilino (p-carbo-2'-ethyl-1'-hexyloxy) -1,3,5-triazine.</li></ul>
