Description

• The present invention relates to cosmetic and dermatological emulsions, in particular skincare cosmetic and dermatological emulsions. In a preferred embodiment, the present invention relates to a use which permits the stability of electrolyte-containing preparations, in particular emulsions, preferably of O/W emulsions, to be increased. [0001]
• The skin is the largest human organ. Amongst its many functions (for example for temperature regulation and as a sensory organ) the barrier function, which prevents the skin (and ultimately the entire organism) from drying out, is by far the most important. At the same time, the skin acts as a protective device against the penetration and absorption of external substances. This barrier function is effected by the epidermis, which, as the outermost layer, forms the actual protective sheath against the environment. Being about one tenth of the total thickness, it is also the thinnest layer of the skin. [0002]
• The epidermis is a stratified tissue in which the outer layer, the horny layer (Stratum corneum), is the part which is of significance for the barrier function. The Elias skin model, which is currently recognized in the specialist field (P. M. Elias, [0003] Structure and Function of the Stratum Corneum Permeability Barrier, Drug Dev. Res. 13, 1988, 97-105), describes the horny layer as a two-component system, similar to a brick wall (bricks and mortar model). In this model, the horny cells (corneocytes) correspond to the bricks, and the lipid membrane in the intercellular spaces, which is of complex composition, corresponds to the mortar. This system is essentially a physical barrier to hydrophilic substances, but, because of its narrow and multilayered structure, can equally, however, also be passed by lipophilic substances only with difficulty.
• The present invention relates, in a particular embodiment, to cosmetic or pharmaceutical preparations having a reduced feel of stickiness, to processes for their preparation, and the use of active ingredients for reducing the feel of stickiness of cosmetic preparations. [0004]
• Apart from its barrier action against external chemical and physical influences, the epidermal lipids also contribute to the holding together of the horny layer and have an effect on the smoothness of the skin. In contrast to the sebaceous gland lipids, which do not form a continuous film on the skin, the epidermal lipids are distributed over the entire horny layer. [0005]
• The extremely complex interaction of the moisture-binding substances and of the lipids of the upper layers of the skin is very important for the regulation of skin moisture. For this reason, cosmetics generally comprise, in addition to balanced lipid mixtures and water, water-binding substances. [0006]
• As well as the chemical composition, however, the physical behavour of these substances is also of importance. The development of very biocompatible emulsifiers and surfactants is therefore desirable. Products formulated therewith aid the liquid-crystalline organization of the intercellular lipids of the Stratum corneum, thereby improving the barrier properties of the horny layer. It is particularly advantageous if their molecular constituents consist of substances which are naturally occurring in the epidermis. [0007]
• Cosmetic skin care primarily means that the natural function of the skin as a barrier against environmental influences (e.g. dirt, chemicals, microorganisms) and against the loss of endogenous substances (e.g. water, natural fats, electrolytes) is strengthened or rebuilt. [0008]
• If this function is impaired, increased resorption of toxic or allergenic substances or attack by microorganisms may result, leading to toxic or allergic skin reactions. [0009]
• Another aim of skin care is to compensate for the loss by the skin of lipids and water caused by daily washing. This is particularly important when the natural regeneration ability is insufficient. Furthermore, skincare products should protect against environmental influences, in particular against sun and wind, and delay skin ageing. [0010]
• Medicinal topical compositions generally comprise one or more medicaments in an effective concentration. For the sake of simplicity, in order to distinguish clearly between cosmetic and medicinal use and corresponding products, reference is made to the legal provisions in the Federal Republic of Germany (e.g. Cosmetics Directive, Foods and Drugs Act). [0011]
• Customary cosmetic forms of application are emulsions. This term generally means a heterogeneous system of two liquids which are immiscible or miscible only to a limited extent with one another, which are usually referred to as phases. One is in the form of droplets (disperse or internal phase), whilst the other liquid forms a continuous (coherent or internal) phase. Less common forms of application are multiple emulsions, i.e. those which, in the droplets of the dispersed (or discontinuous) phase, comprise for their part droplets of a further dispersed phase, e.g. W/O/W emulsions and O/W/O emulsions. [0012]
• More recent findings have recently led to a better understanding of cosmetic emulsions which are of relevance in practice. Here, it is assumed that the emulsifier mixtures used in excess form lamellar liquid-crystalline phases or crystalline gel phases. In the gel network theory, stability and physicochemical properties of such emulsions are attributed to the formation of viscoelastic gel networks. [0013]
• In order to be able to ensure the metastability of emulsions, interface-active substances, i.e. emulsifiers, are usually necessary. The use per se of customary cosmetic emulsifiers is entirely acceptable. Nevertheless, emulsifiers, as ultimately any chemical substance, may in certain cases cause allergic reactions or reactions based on oversensitivity of the user. For example, it is known that in some particularly sensitive people, certain light dermatoses are triggered by certain emulsifiers and simultaneous action of sunlight. [0014]
• It is possible to prepare emulsifier-free preparations which, for example, have, in an aqueous phase, dispersed oil droplets, similar to an O/W emulsion. A prerequisite for this may be that the continuous aqueous phase has a gel framework which stabilizes the dispersed phase, and other conditions besides. Such systems are sometimes called hydrodispersions or oleodispersions depending on which is the disperse phase and which is the continuous phase. [0015]
• For cosmetic technology, it is, however, neither necessary nor possible to dispense with emulsifiers altogether, especially since there is a certain choice of particularly mild emulsifiers. However, the prior art lacks a satisfactorily broad range of such emulsifiers which would then also significantly broaden the application spectrum of correspondingly mild cosmetic preparations which are tolerated by the skin. [0016]
• An object of the present invention was therefore to provide cosmetic and dermatological preparations having excellent skincare properties. [0017]
• A disadvantage, in particular of O/W emulsions, is often their inadequate stability to relatively high electrolyte concentrations, which manifests itself in phase separation. This can indeed sometimes lead to problems, even in the case of W/O emulsions, although this is by no means as important here as in the case of O/W systems. Although these can often be remedied to a certain extent through appropriate choice of the emulsifier system, other disadvantages, however, arise just as often. [0018]
• On the other hand, it is often desireable to use certain electrolytes in order to be able to utilize their other physical, chemical or physiological properties. [0019]
• The concentrations of all of the constituents of a cosmetic or dermatological preparation are usually chosen in units such as % by weight, mol % and the like. In view of their greater or lesser dissociation into cations and anions, often in several dissociation stages, it sometimes appears more advantageous for the description of the present invention and its technical background, to start from the ionic strength of a given electrolyte in its solution. [0020]
• The ionic strength I of an electrolyte solution is defined as [0021] $I=\frac{1}{2}\sum _i^{}c_iz_i^2$

  
• where c[0022] _i or the concentrations of the individual types of ion (in mol/l) and z_i are their charges. The physical unit of ionic strength is that of a concentration (mol/l).
• For example, a 1% strength (=0.17 molar) sodium chloride solution has an ionic strength I=0.17. [0023]
• Another object of the present invention was therefore to discover ways of producing cosmetic or dermatological emulsions, in particular O/W emulsions, which are stable to increased electrolyte concentrations—or increased ionic strengths. [0024]
• It was furthermore an object of the present invention to provide preparations which significantly improve the condition of the skin, in particular reduce skin roughness. [0025]
• It is known that certain substances, for example a few selected powder raw materials, in particular talc, can be added to reduce a feeling of stickiness and also a feeling of greasiness. However, apart from the fact that this is only rarely completely successful, such an addition also changes the viscosity of the product in question and lowers the stability. [0026]
• The object was therefore to remedy all of these disadvantages of the prior art. In particular, the intention was to provide products having reduced stickiness or greasiness. Products in the field of care cosmetics, decorative cosmetics and pharmacological technology should likewise be freed from the described disadvantages of the prior art. [0027]
• Furthermore, it was an object of the invention to develop cosmetic bases for cosmetic preparations which are characterized by good skin compatibility. [0028]
• Furthermore, it was an object of the present invention to provide products with as broad an application diversity as possible. For example, the intention was to provide bases for preparation forms such as cleansing emulsions, face and bodycare preparations, and also distinctly medicinal-pharmaceutical administration forms, for example preparations for treating acne and other skin conditions. [0029]
• Surprisingly, it has been found, and herein lies the solution to these problems, that cosmetic and dermatological preparations in the form of O/W emulsions, comprising [0030]
• (1) 0.1 up to 5% by weight, based on the total weight of the preparations, of one or more C[0031] ₁₄-C₂₂-fatty acids,
• (2) 0.2 up to 10% by weight, based on the total weight of the preparations, of one or more mono- and/or diglycerides of fatty acids, [0032]
• (3) 0.1 up to 5% by weight, based on the total weight of the preparations, of one or more ethoxylated fatty acid esters, [0033]
• where the sum of (1), (2) and (3) is at most 12% by weight, [0034]
• (4) 0.5 to 10% by weight, based on the total weight of the preparations, of one or more nonpolar lipids, [0035]
• (5) 0.5-7.5% by weight, based on the total weight of the preparations, of one or more fatty alcohols [0036]
• (6) 0.5-7.5% by weight, based on the total weight of the preparations, of one or more lipophilic bodying agents having a melting point or dropping point of ≧30° C. [0037]
• (7) where the total lipid phase can comprise up to 40% by weight of polar lipids, based on the total weight of the lipid phase, [0038]
• overcome the disadvantages of the prior art. [0039]
• It was therefore not foreseeable by the person skilled in the art that the preparations according to the invention would [0040]
• be more effective moisture-donating preparations, [0041]
• better promote skin smoothing, [0042]
• be characterized by better care action, [0043]
• be better vehicles for cosmetic and medicinal-dermatological active ingredients [0044]
• have higher stability to decomposition in oil and water phases and [0045]
• would be characterized by better biocompatibility [0046]
• would be characterized by better feel on the skin and by higher cosmetic elegance than the prior art preparations. [0047]
• The preparations according to the invention can be formulated both in flowable form and also in cream form, have very good cosmetic properties, in particular with regard to stickiness, and have very good skin compatibility and skincare performance. [0048]
• Advantageous embodiments of the present invention relate to cosmetic and dermatological preparations according to the main claim, comprising [0049]

• Particularly advantageous embodiments of the present invention are obtained when they relate to cosmetic and dermatological preparations according to the main claim, comprising [0057]
• (3) up to 5% by weight, based on the total weight of the preparations, of one or more ethoxylated fatty acid esters chosen from the group of PEG-20 to PEG-100 stearates. [0058]
• It is particularly advantageous to choose weight ratios between the constituents given under (1), (2) and (3) of approximately 1:4:2. [0059]
• (5) 0.5 to 10% by weight, based on the total weight of the preparations, of one or more nonpolar lipids, chosen from the group of mineral oil and/or mineral waxes (including Vaseline). [0060]
• Furthermore, advantageous embodiments of the present invention are obtained if these relate to cosmetic and dermatological preparations according to the main claim, comprising [0061]
• (6) 2.0-3.0% by weight, based on the total weight of the preparations, of one or more fatty alcohols. [0062]
• Furthermore, advantageous embodiments of the present invention are obtained if these relate to cosmetic and dermatological preparations according to the main claim, comprising [0063]
• (7) 1.5-2.5% by weight, based on the total weight of the preparations, of one or more lipophilic bodying agents having a melting point or dropping point of ≧30° C. [0064]
• For the purposes of the present disclosure, the general term for fats, oils, waxes and the like which is sometimes used is the expression “lipids”, with which the person skilled in the art is entirely familiar. The terms “oily phase”. and “lipid phase” are also used synonymously. [0065]
• Oils and fats differ from one another in their polarity, which is difficult to define. It has already been proposed to adopt the interfacial tension towards water as a measure of the polarity index of an oil or of an oily phase. Then, the lower the interfacial tension between this oily phase and water, the greater the polarity of the oily phase in question. According to the invention, the interfacial tension is regarded as one possible measure of the polarity of a given oil component. [0066]
• The interfacial tension is the force which acts on an imaginary line one metre in length in the interface between two phases. The physical unit for this interfacial tension is conventionally calculated from the force/length relationship and is usually expressed in mN/m (millinewtons divided by metres). It has a positive sign if it endeavours to reduce the interface. In the converse case, it has a negative sign. For the purposes of the present invention, lipids are regarded as polar if their interfacial tension towards water is less than 30 mN/m. [0067]
• Polar oils are for example those from the group of lecithins and of fatty acid triglycerides, namely the triglycerol esters of saturated and/or unsaturated, branched and/or unbranched alkanecarboxylic acids having a chain length of from 8 to 24, in particular 12 to 18, carbon atoms. The fatty acid triglycerides can, for example, advantageously be chosen from the group of synthetic, semisynthetic and natural oils, such as, for example, olive oil, sunflower oil, soya oil, peanut oil, rapeseed oil, almond oil, palm oil, coconut oil, castor oil, wheatgerm oil, grapeseed oil, thistle oil, evening primrose oil, macadamia nut oil and the like. [0068]
• Other polar oil components can be chosen from the group of esters of saturated and/or unsaturated, branched and/or unbranched alkanecarboxylic acids having a chain length of from 3 to 30 carbon atoms and saturated and/or unsaturated, branched and/or unbranched alcohols having a chain length of from 3 to 30 carbon atoms, and from the group of esters of aromatic carboxylic acids and saturated and/or unsaturated, branched and/or unbranched alcohols having a chain length of from 3 to 30 carbon atoms. Such ester oils can then advantageously be chosen from the group consisting of isopropyl myristate, isopropyl palmitate, isopropyl stearate, isopropyl oleate, n-butyl stearate, n-hexyl laurate, n-decyl oleate, isooctyl stearate, isononyl stearate, isononyl isononanoate, 2-ethylhexyl palmitate, 2-ethylhexyl laurate, 2-hexyldecyl stearate, 2-octyldodecyl palmitate, oleyl oleate, oleyl erucate, erucyl oleate, erucyl erucate and synthetic, semisynthetic and natural mixtures of such esters, such as, for example, jojoba oil. [0069]
• In addition, the oily phase can be advantageously chosen from the group of dialkyl ethers, the group of saturated or unsaturated, branched or unbranched alcohols. It is particularly advantageous if the oily phase of the W/O emulsions according to the invention contains C[0070] _12-15-alkyl benzoate or consists entirely of the latter.
• Any mixtures of such oil and wax components can also be used advantageously for the purposes of the present invention. It may also be advantageous to use waxes, for example cetyl palmitate, as the sole lipid component of the oily phase. [0071]
• Nonpolar oils are, for example, those which are chosen from the group of branched and unbranched hydrocarbons and hydrocarbon waxes, in particular Vaseline (petrolatum), paraffin oil, squalane and squalene, polyolefins and hydrogenated polyisobutenes. Of the polyolefins, polydecenes are the preferred substances. Table 1 below lists lipids which are advantageous according to the invention as individual substances and also as a mixture with one another. The respective interfacial tensions towards water are given in the last column. It is, however, also advantageous to use mixtures of more or less polar substances and the like, provided it is ensured that the overall polarity of the oily phase lies within the claimed range.

• For the purposes of the present invention, medicinal topical compositions generally comprise one or more medicaments in an effective concentration. For the sake of simplicity, in order to distinguish clearly between cosmetic and medicinal use and corresponding products, reference is made to the legal provisions in the Federal Republic of Germany (for example Cosmetics Directive, Foods and Drugs Act). [0096]
• Accordingly, for the purposes of the present invention, cosmetic or topical dermatological compositions can, depending on their composition, be used for example as skin protection cream, cleansing milk, sunscreen lotion, nourishing cream, day or night cream, etc. If desired, it is possible and advantageous to use the compositions according to the invention as a base for pharmaceutical formulations. [0097]
• It is likewise advantageous to make use of the properties according to the invention in the form of decorative cosmetics (make-up formulations). [0098]
• Those cosmetic and dermatological preparations which are in the form of a sunscreen are also favourable. In addition to the active ingredient used according to the invention, these also preferably comprise at least one UVA filter substance and/or at least one UVB filter substance and/or at least one inorganic pigment. [0099]
• However, it is also advantageous for the purposes of the present invention to provide cosmetic and dermatological preparations whose main purpose is not protection against sunlight, but which nevertheless contain anti-UV substances. Thus, for example, UV-A and UV-B filter substances are usually incorporated into day creams. [0100]
• Preparations according to the invention can advantageously comprise substances which absorb UV radiation in the UVB region, the total amount of filter substances being, for example, from 0.1% by weight to 30% by weight, preferably from 0.5 to 10% by weight, in particular from 1 to 6% by weight, based on the total weight of the preparations.
