IN THE MATTER OF an Australian Application corresponding to PCT Application PCT/EPO3/03099 RWS Group plc, of Europa House, Marsham Way, Gerrards Cross, Buckinghamshire, England, hereby solemnly and sincerely declares that, to the best of its knowledge and belief, the following document, prepared by one of its translators competent in the art and conversant with the English and German languages, is a true and correct translation of the PCT Application filed under No. PCT/EPO3/03099. Date: 18 October 2004 C. E. SITCH Deputy Managing Director - UK Translation Division For and on behalf of RWS Group plc Beiersdorf Aktlengesellschaft Hamburg 5 Description Water-resistant cosmetic and dermatological iqht protection formulations with a content of acetylated stearic esters 10 The present invention relates to water-resistant cosmetic and dermatological light protection preparations with a content of oil-soluble and/or oil-dispersible acetylated stearic esters, and to the use of such substances for increasing the water resistance of cosmetic and dermatological light protection preparations. 15 The harmful effect of the ultraviolet part of solar radiation on the skin is generally known. Depending on their particular wavelength, the rays have different effects on the skin as an organ: 20 The so-called UV-C radiation with a wavelength between 100 and 280 nm is absorbed by the ozone layer in the Earth's atmosphere and accordingly is not found in the solar spectrum. It is therefore of no physiological importance during sunbathing. The so-called UV-B region is between 290 nm and 320 nm. UV-B rays are essentially 25 responsible for the long-lasting tanning of the skin, but can at the same time cause an erythema, simple sunburn or even burns of greater or lesser severity. Chronic photodamage, photodermatoses and Herpes solaris can also be caused by UV-B radiation. 30 It has for a long time been incorrectly assumed that long-wave UV-A radiation with a wavelength between 320 nm and 400 nm only has a negligible biological effect and that, correspondingly, the UV-B rays are responsible for most photodamage to the human skin. However, in the meantime, numerous studies have shown that UV-A radiation is much more hazardous than UV-B radiation with regard to the triggering of photodynamic, 35 specifically phototoxic reactions and chronic changes in the skin. The harmful influence of UV-B radiation can also be further intensified by UV-A radiation.

2 Thus, it has, inter alia, been found that even UV-A radiation suffices under very normal everyday conditions to harm, within a short time, the collagen and elastin fibers which are of essential importance for the structure and strength of the skin. The consequences are 5 chronic photo-induced changes in the skin - the skin "ages" prematurely. The clinical appearance of skin aged by light includes, for example, wrinkles and lines, and also an irregular, furrowed relief. In addition, the parts affected by photo-induced skin aging have irregular pigmentation. The formation of brown spots, keratoses and even carcinomas or malignant melanomas is also possible. Skin aged prematurely by everyday UV exposure 10 is, moreover, characterized by lower activity of the Langerhans cells and slight, chronic inflammation. Approximately 90% of the ultraviolet radiation which reaches the Earth consists of UV-A rays. While UV-B radiation varies widely depending on numerous factors (e.g. time of 15 year and time of day or degree of latitude), UV-A radiation remains relatively constant day to day irrespective of the time of year and time of day or geographical factors. At the same time, the majority of UV-A radiation penetrates into the living epidermis, while approximately 70% of UV-B rays are retained by the horny layer. 20 The relatively recent findings concerning the effect of UV-A rays on the skin have led to increased attention now being devoted to protective measures for this ray range. In practice, no sunscreen product is complete any more without an effective UV-A filter effect, and pure UV-B filter preparations are rare. 25 When applying a sunscreen to the skin, the ultraviolet rays can be weakened through two effects: firstly, by reflection and scattering of the rays at the surface of pulverulent solids (physical light protection) and, secondly, by absorption on chemical substances (chemical light protection). Depending on which wavelength region is absorbed, a distinction is made between UV-B filters (absorption range 280 to 320 nm), UV-A filters (absorption 30 range 320 to 400 nm) and broadband filters (absorption range 290 to about 380 nm). To protect against UV-B radiation, numerous compounds are known, the absorption maximum of which should be around 308 nm as far as possible since this is the highest erythema effectiveness of solar radiation. Typical UV-B filters are, for example, 35 derivatives of 3-benzylidenecamphor, of 4-aminobenzoic acid, of cinnamic acid, of salicylic acid, of benzophenone, and also of 2-phenylbenzimidazole.

3 Some compounds are also known for protecting against UV-A radiation, such as, in particular, dibenzoylmethane derivatives. However, dibenzoylmethane derivatives are generally not photostable, as a result of which cosmetic or dermatological preparations 5 with a content of this substance should also comprise certain UV stabilizers. Further known UV-A filter substances are certain water-soluble, sulfonated UV filter substances, such as, for example, phenylene-1, 4 -bis( 2 -benzimidazyl)-3,3'-5,5'-tetrasulfonic acid and its salts. 10 Besides the pure UV-A or UV-B filters, there are substances which cover both regions. This group of broadband filters includes, for example, asymmetrically substituted s-triazine compounds, such as, for example, 2,4-bis{[4-(2-ethylhexyloxy)-2 hydroxy]phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI: BisEthyihexyloxyphenol Methoxyphenyl Triazine), certain benzophenones, such as, for example, 2-hydroxy-4 15 methoxybenzophenone (INCI: Benzophenone 3) or 2,2'-methylenebis(6-(2H-benzotriazol 2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol) (INCI: Methylene Bis-Benzotriazolyl Tetramethylenebutylphenol). In general, the light absorption behavior of light protection filter substances is very well 20 known and documented, especially as there are positive lists for the use of such substances in most industrialized countries, which impose very strict standards on the documentation. Since, in order to characterize a filter substance, not only is the position of the absorption maximum important, but primarily the absorption range, absorption spectra are recorded for each substance. However, the absorbance values can at best 25 be a guide for the concentration of the substances in the finished formulations since interactions with ingredients of the skin or of the surface of the skin itself may give rise to imponderables. In addition, it is usually difficult to estimate beforehand how uniformly and thickly the filter substance is distributed in and on the horny layer of the skin. 30 To test the UV-A protection performance, use is usually made of the IPD method (IPD = immediate pigment darkening). Similarly to the determination of the light protection factor, this method gives a value which indicates how much longer the skin protected with the light protection composition can be irradiated with UV-A radiation until the pigmentation which occurs is the same as for the unprotected skin. 35 4 The use concentration of known light protection filter substances present in the form of a solid, which exhibit a high filter effect in the UV-A region is, however, often limited especially in combination with other substances to be dissolved. This therefore gives rise to certain technical difficulties relating to formulation in achieving relatively high light 5 protection factors or UV-A protection performance. Since light protection filter substances are generally expensive and since some light protection filter substances are also difficult to incorporate into cosmetic or dermatological preparations in relatively high concentrations, it was an object of the 10 invention to arrive, in a simple and cost-effective manner, at preparations which, despite having unusually low concentrations of conventional UV filter substances, nevertheless achieve an acceptable or even high UV-A and/or UB-B protection performance. Emulsions also play the decisive role in the field of sunscreen formulations. Preference is 15 given here to flowable or low-viscosity emulsions since they can be applied more easily than high-viscosity creams. Most sunscreens are employed in the vicinity of water or during sporting activity (perspiration), for which reason the water resistance of such formulations is to be 20 attributed particular importance. A water-resistant sunscreen protects the user not only after bathing, but also protects him against sunburn during bathing. It is a widespread - misconception that water offers good or even adequate protection against ultraviolet radiation. Rather, investigations have shown that even 1 m below the surface of the water, the transmittance for UV-B rays is about 50%. It is therefore advisable for those 25 who participate in watersports, who, for example, swim, surf or snorkel, and in particular children, who often play for hours at or in the water, to also protect the skin against overly intense and excessive solar irradiation with a sun product which adheres well and can only be rinsed off with difficulty by water and perspiration. 30 In order to achieve high light protection factors coupled with very good water resistance, W/O formulations are generally advantageous. However, W/O emulsions often have unsatisfactory cosmetic properties: upon application, they can leave behind a greasy, shiny and sometimes tacky impression on the skin and are difficult to spread - particularly on hair-covered skin. 35 5 By contrast, O/W emulsions are less greasy on the skin, have more of a matting effect and absorb more rapidly into the skin. They are generally perceived by the consumer as being lighter and cosmetically more elegant than W/O emulsions. However, since water is the external phase, O/W emulsions are usually only water-resistant to a limited degree. 5 In order to improve the water resistance of cosmetic and dermatological light protection preparations, it may be advantageous to incorporate film formers into the cosmetic or dermatological preparations. According to the prior art, polyurethanes (e.g. the Avalure@ grades from Goodrich), dimethicone copolyol polyacrylate (Silsoft Surface@ from Witco 10 Organo Silicones Group), PVPNA (VA = vinyl acetate) copolymer (Luviscol VA 64 powder from BASF), C 2 o.

4 o carboxylic acid with polyethylene (Performacid 350 from New Phase Technologies), and film formers from the group of polymers based on polyvinylpyrrolidone (PVP): - C--CH-CH2- 15 o for example are suitable for this purpose. Particular preference is given to using copolymers of polyvinylpyrrolidone, for example 20 the PVP hexadecene copolymer and the PVP eicosene copolymer, which are available under the trade names Antaron V216 and Antaron V220 from GAF Chemicals Cooperation, and also tricontayl PVP and the like. However, it is a disadvantage of those preparations which comprise film formers in an 25 effective concentration (i.e. a concentration which increases the water resistance) that they leave behind a sticky and greasy impression when applied to the skin. Besides the influence of the base, the binding ability of the UV filter in or on the skin is also of great importance for the water resistance of the formulation. It will be appreciated 30 that oil-soluble UV filters are better bonded to the (lipophilic) surface of the skin, and are more difficult to wash off than water-soluble UV filters.

6 A further object of the invention was therefore to arrive, in a simple and inexpensive manner, at preparations (in particular at O/W formulations) which are characterized by good water resistance. In particular, preparations were to be found which have a high content of water-soluble UV filters and nevertheless exhibit very good water resistance. 5 It was surprising and could not have been foreseen by the person skilled in the art that the use of oil-soluble and/or oil-dispersible acetylated stearic esters for improving the water resistance of cosmetic or dermatological formulations comprising at least one customary UV filter substance would overcome the disadvantages of the prior art. 10 In addition, it was surprising that the use of oil-soluble and/or oil-dispersible acetylated stearic esters for improving the water resistance of O/W formulations would overcome the disadvantages of the prior art. 15 Moreover, it was particularly surprising that the use of oil-soluble and/or oil-dispersible acetylated stearic esters for improving the water resistance of cosmetic or dermatological formulations comprising at least one customary water-soluble UV filter substance would overcome the disadvantage of the prior art. 20 The preparations according to the present invention are satisfactory preparations in every respect which are not limited to a restricted choice of raw material. Accordingly, they are suitable very particularly as a basis for preparation forms with diverse intended uses. The preparations according to the present invention exhibit very good sensory and cosmetic properties, such as, for example, spreadability on the skin or the ability to absorb into the 25 skin, and are further characterized by very good light protection effectiveness, extremely high UV-A and/or UV-B protection performance, and by excellent water resistance coupled with excellent skin care data. It was particularly surprising that it is possible to dispense entirely with customary film formers which are used according to the prior art for increasing the water resistance. 30 It was very particularly surprising that the use of oil-soluble and/or oil-dispersible acetylated stearic esters also improves the UV-A and UV-B protection performance of cosmetic or dermatological formulations comprising at least one customary UV filter substance since the substances used according to the invention themselves exhibit no 35 absorption performance at all in the UV region.

7 Although hitherto there is still no approved method throughout Europe for determining the water resistance of cosmetic or dermatological light protection formulations, the prior art recognises a series of possible investigative methods: the preparation to be investigated is applied to the skin and the light protection factor is determined. Water is then allowed 5 to come into contact with the skin for a certain time and then the light protection factor is determined again. This basic measurement principle is the same for all methods. However, differences exist in the details of the experimental arrangement, such as, for example, the type of contact (basin/whirlpool or vigorous shower), the water contact time, the water temperature or the type of water used (tapwater, salt water or chlorinated 10 water). For the purposes of the present invention, preparations are referred to as water-resistant if they still have at least 50% of the original light protection factor after the following test: * application of 2 mg/cm 2 of the preparation to be investigated to two areas of skin 15 (preferably on the backs of the subjects) * 15 to 30 minutes contact (waiting) * determination of the (original) light protection factor on one of the two areas * 2 x 20 minute contact with water (tapwater) in the whirlpool at 25 to 356C (at least 15 minutes pause between the baths) 20 * 15 to 30 minute drying (waiting) * determination of the light protection factor on the other of the two areas. The abovementioned criterion for the water resistance of the tested product accordingly arises from the quotient of the light protection factors (LPF) determined before and after 25 the water contact: LPF PF'. 100% LPFre It was particularly surprising that the preparations for the purposes of the present invention are also water-resistant to salt water (seawater, perspiration) and even 30 chlorinated water (swimming pool) and can accordingly also be referred to as perspiration-resistant and chlorinated water-resistant. A particularly advantageous acetylated stearic ester for the purposes of the present invention is acetylated glycol stearate. According to the invention, it can also be 35 advantageous to use the combination of acetylated glycol stearate with tristearin (INCI: 8 Acetylated Glycol Stearate and Tristearin), which is available, for example, under the trade name Unitwix from ISP. Such products are registered under the Chemical Abstracts registry numbers 91052-08-3 and 94944-95-3. 5 For the purposes of the present invention, cosmetic or dermatological preparations comprise - based on the total weight of the preparations - advantageously 0.1 to 8% by weight, in particular 0.5 to 5% by weight, of one or more acetylated stearic esters. Besides one or more oil phases, the preparations for the purposes of the present 10 invention can preferably additionally comprise one or more water phases and be present, for example, in the form of W/O, O/W, W/O/W OR O/W/O emulsions. Such formulations can preferably also be microemulsions, sticks, foams (so-called mousse), solid emulsions (i.e. emulsions which are stabilized by solids, e.g. Pickering emulsions), sprayable emulsions or hydrodispersions. Furthermore, the preparations may advantageously also 15 be oil-free and/or aqueous/alcoholic solutions. According to the invention, (macroscopically) two- or multi-phase systems are also advantageous. For the purposes of the present invention, "two- or multi-phase" means that two or more phases are present in separate layers one above the other. For the 20 purposes of the present invention, it is particularly advantageous if at least one of the macroscopically visible phases is a (W/O, O/W, micro-) emulsion. Upon this (macroscopic) examination, the emulsion is perceived as being one phase although it is of course known to the person skilled in the art that emulsions are per se formed from two or more phases homogenized with one another. The "emulsion phase" has long-term 25 stability meaning that, even over a prolonged period (months, years), demixing and phase separation within the emulsion does not arise. The macroscopically visible phases and layers can advantageously be emulsified - for example by shaking - in the short term to give a homogeneous emulsion, although this does not have long-term stability, but separates again to give two or more layered phases 30 over a period of minutes, hours or days. For the purposes of the present invention, it is particularly advantageous if at least one of the macroscopically visible phases is a microemulsion and at least one of the other macroscopically visible phases is an oil phase. 35 Sprayable emulsions, in particular mcroemulsions 9 For the purposes of the present invention, sprayable O/W emulsions, in particular O/W microemulsions, are particularly advantageous. The droplet diameters of the customary "simple", i.e. non-multiple, emulsions are in the 5 range from about 1 pm to about 50 pm. Such "macroemulsions" are, without further coloring additives, milky-white in color and opaque. Finer "macroemulsions", the droplet diameters of which are in the range from about 0.5 pm to about 1 pm, are, again without coloring additives, bluish-white in color and opaque. Such "macroemulsions" usually have a high viscosity. 10 The droplet diameter of microemulsions for the purposes of the present invention, by contrast, is in the range from about 50 to about 500 nm. Such microemulsions are bluish white in color to translucent and in most cases of low viscosity. The viscosity of many microemulsions of the O/W type is comparable with that of water. 15 An advantage of microemulsions is that active ingredients can be present in an essentially more finely disperse form in the disperse phase than in the disperse phase of "macroemulsions". A further advantage is that, due to their low viscosity, they are sprayable. If microemulsions are used as cosmetics, corresponding products are 20 characterized by high cosmetic elegance. Advantageous according to the invention are, in particular, O/W microemulsions which are obtainable using the so-called phase-inversion temperature technology and comprise at least one emulsifier (emulsifier A), which is chosen from the group of emulsifiers with 25 the following properties: * their lipophilicity is dependent on the temperature, such that by increasing the temperature the lipophilicity increases, and by reducing the temperature the lipophilicity of the emulsifier decreases. 30 Advantageous emulsifiers A are, for example, polyethoxylated fatty acids (PEG-100 stearate, PEG-20 stearate, PEG-150 laureate, PEG-8 distearate and the like) and/or polyethoxylated fatty alcohols (cetearath-12, cetearath-20, isoceteth-20, beheneth-20, laureth-9 etc.) and/or alkyl polyglycosides (cetearyl glycoside, stearyl glycoside, palmityl glycoside etc.). 35 If the phase inversion is triggered essentially by varying the temperature, O/W emulsions, in particular O/W microemulsions, are obtainable, the size of the oil droplets being 10 determined essentially by the concentration of the emulsifier(s) used in such a way that a higher emulsifier content brings about smaller droplets and a lower emulsifier content leads to larger droplets. The droplet sizes are usually between 20 and 500 nm. 5 For the purposes of the present invention, it is in some instances advantageous to use further W/O and/or O/W emulsifiers which are not covered by the definition of emulsifier A, for example in order to increase the water resistance of the preparations according to the invention. For example, alkylmethicone copolyols and/or alkyldimethicone copolyols (in particular cetyl dimethicone copolyol, lauryl methicone copolyol), W/O emulsifiers 10 (such as, for example, sorbitan stearate, glyceryl stearate, glycerol stearate, sorbitan oleate, lecithin, glyceryl isostearate, polyglyceryl-3 oleate, polyglyceryl-3 diisostearate, PEG-7 hydrogenated castor oil, polyglyceryl-4 isostearate, acrylate/Clo- 1 -alkyl acrylate crosspolymer, sorbitan isostearate, poloxamer 101, polyglyceryl-2 dipolyhydroxystearate, polyglyceryl-3 diisostearate, polyglyceryl-4 dipolyhydroxystearate, PEG-30 15 dipolyhydroxystearate, diisostearoyl polyglyceryl-3 diisostearate, glycol distearate, polyglyceryl-3 dipolyhydroxystearate) and/or fatty acid esters of sulfuric acid or phosphoric acid (cetyl phosphate, trilaureth-4 phosphate, trioleth-8 phosphate, stearyl phosphate, cetearyl sulfate etc.) can be used. 20 Further advantageous sprayable O/W emulsions for the purposes of the present invention are low-viscosity cosmetic or dermatological hydrodispersions which comprise at least one oil phase and at least one water phase, where the preparation is stabilized by at least one gel former and does not necessarily have to comprise emulsifiers, but may comprise one or more emulsifiers. 25 Advantageous gel formers for such preparations are, for example, copolymers of Cso alkyl acrylates and one or more monomers of acrylic acid, of methacrylic acid or esters thereof. The INCI name for such compounds is "Acrylates/C10-30 Alkyl Acrylate Crosspolymer". The Pemulene grades TR1, TR2 and TRZ from Goodrich (Noveon) are 30 particularly advantageous. Carbopols are also advantageous gel formers for such preparations. Carbopols are polymers of acrylic acid, in particular also acrylate-alkyl acrylate copolymers. Advantageous carbopols are, for example, the grades 907, 910, 934, 940. 941, 951, 954, 35 980, 981, 1342, 1382, 2984 and 5984, likewise the ETD grades 2020, 2050 and 11 Carbopol Ultrez 10. Further advantageous gel formers for such preparations are xanthan gum, cellulose derivatives and carob seed flour. Possible (optional) emulsifiers which may be used are ethoxylated fatty alcohols or 5 ethoxylated fatty acids (in particular PEG-100 stearate, ceteareth-20) and/or other nonionic surface-active substances. The very low-viscosity to sprayable emulsions may also advantageously be W/O emulsions or water-in-silicone oil (W/S) emulsions. W/O and/or W/S emulsions which 10 comprise * at least one silicone emulsifier (W/S) with a HLB value of _ 8 and/or at least one W/O emulsifier with a HLB value of < 7 and * at least one O/W emulsifier with a HLB value of > 10 are particularly advantageous. 15 Such preparations further comprise at least 20% by weight of lipids, where the lipid phase can also advantageously comprise silicone oils, or even consist entirely of such oils. The silicone emulsifier or emulsifiers can advantageously be chosen from the group of 20 alkyl methicone copolyols and/or alkyldimethicone copolyols (e.g. dimethicone copolyols which are sold by Goldschmidt AG under the trade names ABIL B 8842, Abil e B 8843, Abil B8847, Abil e B 8851, Abil ® B 8852, Abil ® B 8863, Abilo B 8873 and Abil B 88183, cetyl dimethicone copolyol [Goldschmidt AG/Abile EM 90], cyclomethicone dimethicone copolyol [Goldschmidt AG/Abil' EM 97], lauryl methicone copolyol [Dow Coming Ltd./ 25 Dow Comings 5200 Formulation Aid], octyl dimethicone ethoxyglucoside [Wacker]. The W/O emulsifier or emulsifiers with a HLB value of < 7 can advantageously be chosen from the following group: sorbitan stearate, sorbitan oleate, lecithin, glyceryl lanolate, lanolin, hydrogenated castor oil, glyceryl isostearate, polyglyceryl-3 oleate, pentaerythrityl 30 isostearate, methylglucose dioleate, methylglucose dioleate in a mixture with hydroxystearate and beeswax, PEG-7 hydrogenated castor oil, polyglyceryl-4 isostearate, hexyl laurate, acrylate/C 1 oo-alkyl acrylate crosspolymer, sorbitan isostearate, polyglyceryl-2 dipolyhydroxystearate, polyglyceryi-3 diisostearate, PEG-30 dipolyhydroxystearate, diisostearoyl polyglyceryl-3 diisostearate, polyglyceryl-3 35 dipolyhydroxystearate, polyglyceryl-4 dipolyhydroxystearate, polyglyceryl-3 dioleate.

12 The O/W emulsifier or emulsifiers with a HLB value of > 10 can advantageously be chosen from the following group: glyceryl stearate in a mixture with ceteareth-20, ceteareth-25, ceteareth-6 in a mixture with stearyl alcohol, cetylstearyl alcohol in a mixture with PEG-40 castor oil and sodium cetylstearyl sulfate, triceteareth-4 phosphate, 5 glyceryl stearate, sodium cetylstearyl sulfate, lecithin trilaureth-4 phosphate, laureth-4 phosphate, stearic acid, propylene glycol stearate SE, PEG-9 stearate, PEG-20 stearate, PEG-30 stearate, PEG-40 stearate, PEG-100 stearate, ceteth-2, ceteth-20, polysorbate 20, polysorbate-60, polysorbate-65, polysorbate-100, glyceryl stearate in a mixture with PEG-100 stearate, ceteareth-3, isostearyl glyceryl ether, cetylstearyl alcohol in a mixture 10 with sodium cetylstearyl sulfate, PEG-40 stearate, glycol distearate, polyglyceryl-2 PEG-4 stearate, ceteareth-12, ceteareth-20, ceteareth-30, methylglucose sesquistearate, steareth-10, PEG-20 stearate, steareth-21, steareth-20, isosteareth-20, PEG-45/dodecyl glycol copolymer, glyceryl stearate SE, ceteth-20, PEG-20 methylglucose sesquistearate, glyceryl stearate citrate, cetyl phosphate, cetearyl sulfate, sorbitan sesquioleate, 15 triceteareth-4 phosphate, trilaureth-4 phosphate, polyglyceryl methyiglucose distearate, potassium cetyl phosphate, isosteareth-10, polyglyceryl-2 sesquiisostearate, ceteth-10, isoceteth-20, glyceryl stearate in a mixture with ceteareth-20, ceteareth-12, cetylstearyl alcohol and cetyl palmitate, PEG-30 stearate, PEG-40 stearate, PEG-100 stearate. 20 Aqueous-alcoholic solutions are also advantageous. They can comprise from 0% by weight to 90% by weight of ethanol. Aqueous-alcoholic solutions for the purposes of the present invention may advantageously also comprise solubility promoters, such as, for example, PEG-40 or PEG-60 hydrogenated castor oil. 25 The preparations according to the invention can advantageously also be used as cosmetic or dermatological impregnation solutions with which water-insoluble substrates in particular - such as, for example, woven or nonwoven wipes - are moistened. Impregnation solutions of this type are preferably of low viscosity, in particular sprayable (such as, for example, PIT emulsions, hydrodispersions, W/O emulsions, oils, aqueous 30 solutions etc.) and preferably have a viscosity of less than 2000 mPa- s, in particular less than 1500 mPa -s (measuring device: Haake Viskotester VT-02 at 25 0 C). They can be used to obtain, for example, cosmetic sunscreen wipes, care wipes and the like, which represent the combination of a soft, water-insoluble material with the low viscosity cosmetic and dermatological impregnation solution.

13 Oils The preparations according to the invention can advantageously also be in the form of water-free oils or oil gels or pastes. Advantageous oils are, for example, synthetic, 5 semisynthetic or natural oils, such as, for example, rapeseed oil, rice oil, avocado oil, olive oil, mineral oil, cocoglycerides, butylene glycol dicaprylate/dicaprate, C12.15 alkylbenzoate, dicaprylyl carbonate, octyldodecanol and the like. Oil gel formers which may be used are diverse waxes with a melting point > 250C. Also advantageous are gel formers from the group of Aerosils, of alkyl galactomannans (e.g. N-Hance AG 200 and 10 N-Hance AG 50 from Hercules) and polyethylene derivatives. Mousses 15 Also particularly advantageous for the purposes of the present invention are self foaming, foam-like, after-foaming or foamable cosmetic and dermatological preparations. "Self-foaming", "foam-like", "after-foaming" and "foamable" preparations are understood as meaning preparations from which foams can in principle be produced by introducing 20 one or more gases - whether during the preparation process, whether upon use by the consumer or in another way. In such foams, the gas bubbles are (randomly) distributed in one (or more) liquid phase(s), where the (foamed) preparations do not necessarily have to have the appearance of a foam in macroscopic terms. Foamed cosmetic or dermatological preparations according to the invention (referred to below for the sake of 25 simplicity also as foams) may, for example, be macroscopically visibly dispersed systems of gases dispersed in liquids. The foam character may, however, for example also only be visible under a (light) microscope. Moreover, foams according to the invention particularly when the gas bubbles are too small to be seen under a light microscope - are also evident from the considerable volume increase of the system. 30 For the purposes of the present invention, such preparations advantageously comprise an emulsifier system which consists of A. at least one emulsifier A chosen from the group of completely neutralized, partially neutralized or unneutralized branched and/or unbranched, saturated and/or 35 unsaturated fatty acids with a chain length of from 10 to 40 carbon atoms, 14 B. at least one emulsifier B chosen from the group of polyethoxylated fatty acid esters with a chain length of from 10 to 40 carbon atoms and with a degree of ethoxylation of from 5 to 100 and C. at least one coemulsifier C chosen from the group of saturated and/or 5 unsaturated, branched and/or unbranched fatty alcohols with a chain length of from 10 to 40 carbon atoms. The emulsifier or emulsifiers A are preferably chosen from the group of fatty acids, which are completely or partially neutralized with customary alkalis (such as, for example, 10 sodium hydroxide and/or potassium hydroxide, sodium carbonate and/or potassium carbonate, and mono- and/or triethanolamine). Stearic acid and stearates, isostearic acid and isostearates, palmitic acid and palmitates, and myristic acid and myristates, for example, are particularly advantageous. 15 The emulsifier or emulsifiers B are preferably chosen from the following group: PEG-9 stearate, PEG-8 distearate, PEG-20 stearate, PEG-8 stearate, PEG-8 oleate, PEG-25 glyceryl trioleate, PEG-40 sorbitan lanolate, PEG-15 glyceryl ricinoleate, PEG-20 glyceryl stearate, PEG-20 glyceryl isostearate, PEG-20 glyceryl oleate, PEG-20 stearate, PEG-20 methylglucose sesquistearate, PEG-30 glyceryl isostearate, PEG-20 glyceryl laurate, 20 PEG-30 stearate, PEG-30 glyceryl stearate, PEG-40 stearate, PEG-30 glyceryl laurate, PEG-50 stearate, PEG-100 stearate, PEG-150 laurate. Polyethoxylated stearic esters, for example, are particularly advantageous. According to the invention, the coemulsifier or the coemulsifiers C are preferably chosen 25 from the following group: behenyl alcohol (C22H 4 sOH), cetearyl alcohol [a mixture of cetyl alcohol (Cle 6 HOH) and stearyl alcohol (C 1 8

H

37 0H)], lanolin alcohols (wool wax alcohols which are the unsaponifiable alcohol fraction of wool wax which is obtained following saponification of wool wax). Cetyl and cetylstearyl alcohol are particularly preferred. 30 It is advantageous according to the invention to choose the weight ratios of emulsifier A to emulsifier B to emulsifier C (A:B:C) as a:b:c, where a, b and c, independently of one another, may be rational numbers from 1 to 5, preferably from 1 to 3. A weight ratio of, for example, 1:1:1 is particularly preferred. 35 For the purposes of the present invention, it is advantageous to choose the total amount of the emulsifiers A and B and of coemulsifier C from the range from 2 to 20% by weight, 15 advantageously from 5 to 15% by weight, in particular from 7 to 13% by weight, in each case based on the total weight of the formulation. Pickering/solids-stabilized emulsions 5 Also particularly advantageous for the purposes of the present invention are cosmetic or dermatological preparations which have been stabilized only by very finely divided solids particles. Such "emulsifier-free" emulsions are also referred to as Pickering emulsions. 10 In Pickering emulsions, the solid material accumulates at the oil/water interface in the form of a layer, as a result of which coalescence of the disperse phases is prevented. Of essential importance here are, in particular, the surface properties of the solids particles, which should exhibit both hydrophilic and also lipophilic properties. 15 The stabilizing solids particles can also advantageously be surface-treated ("coated") to repel water, the intention being to form or retain an amphiphilic character of these solids particles. The surface treatment can consist in providing the solids particles with a thin hydrophobic or hydrophilic layer by processes known per se. 20 The average particle diameter of the microfine solids particles used as stabilizer is preferably chosen to be less than 100 pm, particularly advantageously less than 50 pm. In this connection, it is essentially unimportant in what form (platelets, rods, spheres, etc.) or modifications the solids particles used are present. 25 The microfine solids particles are preferably chosen from the group of amphiphilic metal oxide pigments. In particular, * titanium dioxides (coated and uncoated): e.g. Eusolex T-2000 from Merck, titanium dioxide MT-100 Z from Tayca Corporation * zinc oxides, e.g. Z-Cote and Z-Cote HP1 from BASF AG, MZ-300, MZ-500 and MZ 30 505M from Tayca Corporation * iron oxides are advantageous. Furthermore, it is advantageous when the microfine solids particles are chosen from the 35 following group: boron nitrides, starch derivatives (tapioca starch, sodium corn starch octynyl succinate etc.), talc, latex particles.

16 It is advantageous according to the invention when the solids-stabilized emulsions comprise significantly less than 0.5% by weight of one or more emulsifiers or are even entirely emulsifier-free. 5 Sticks Also advantageous for the purposes of the invention are preparations in the form of sticks. Viewed technically, most stick formulations are anhydrous fatty mixtures of solid 10 or semisolid waxes and liquid oils, where highly purified paraffin oils and paraffin waxes are the stick base. Customary bases for stick preparations are, for example, liquid oils (such as, for example, paraffin oils, castor oil, isopropyl myristate, C 12

.

1 5 alkyl benzoate), semisolid 15 constituents (e.g. vaseline, lanolin), solid constituents (e.g. beeswax, ceresin and microcrystalline waxes and ozokerite) and/or high-melting waxes (e.g. camauba wax, candelilla wax). Water-containing stick preparations are also known per se, it being possible for these also to be present in the form of W/O emulsions. 20 The cosmetic or dermatological light protection formulations according to the invention can have the customary composition and be used for cosmetic or dermatological light - protection, and also for the treatment, care and cleansing of the skin and/or of the hair and as a make-up product in decorative cosmetics. 25 Depending on their formulation, cosmetic or topical dermatological compositions for the purposes of the present invention can, for example, be used as skin protection cream, cleansing milk, day or night cream etc. It is optionally possible and advantageous to use the compositions according to the invention as a base for pharmaceutical formulations. 30 For use, the cosmetic and dermatological preparations are applied to the skin and/or the hair in an adequate amount in the manner customary for cosmetics. The cosmetic and dermatological preparations according to the invention can comprise cosmetic auxiliaries as are customarily used in such preparations, e.g. preservatives, 35 preservative aids, complexing agents, bactericides, perfumes, substances for preventing or increasing foaming, dyes, pigments which have a coloring action, thickeners, 17 moisturizing and/or humectant substances, fillers which improve the feel on the skin, fats, oils, waxes or other customary constituents of a cosmetic or dermatological formulation, such as alcohols, polyols, polymers, foam stabilizers, electrolytes, organic solvents or silicone derivatives. 5 Advantageous preservatives for the purposes of the present invention are, for example, formaldehyde donors (such as, for example, DMDM hydantoin, which is available, for example, under the trade name GlydantTM from Lonza), iodopropyl butylcarbamates (e.g. those available under the trade names Glycacil-L, Glycacil-S from Lonza, and/or 10 Dekaben LMB from Jan Dekker), parabens (i.e. alkyl p-hydroxybenzoates, such as methyl-, ethyl-, propyl- and/or butylparaben), phenoxyethanol, ethanol, benzoic acid and the like. In addition, the preservative system according to the invention also usually advantageously comprises preservative aids, such as, for example, octoxyglycerol, glycine soya etc. 15 Advantageous complexing agents for the purposes of the present invention are, for example, EDTA, [S,S]-ethylenediamine disuccinate (EDDS), which is available, for example, under the trade name Octaquest from Octel, pentasodium ethylenediamine tetramethylenephosphonate, which is available, for example, under the trade name 20 Dequest 2046 from Monsanto and/or iminodisuccinic acid, which is available, inter alia, from Bayer AG under the trade names Iminodisuccinate VP OC 370 (about 30% strength solution) and Baypure CX 100 solid. Particularly advantageous preparations are also obtained when antioxidants are used as 25 additives or active ingredients. According to the invention, the preparations advantageously comprise one or more antioxidants. Favorable, but nevertheless optional, antioxidants which may be used are all antioxidants customary or suitable for cosmetic and/or dermatological applications. 30 For the purposes of the present invention, water-soluble antioxidants may be used particularly advantageously, such as, for example, vitamins, e.g. ascorbic acid and derivatives thereof. Preferred antioxidants are also vitamin E and derivatives thereof, and vitamin A and 35 derivatives thereof.

18 The amount of antioxidants (one or more compounds) in the preparations is preferably 0.001 to 30% by weight, particularly preferably 0.05 to 20% by weight, in particular 0.1 to 10% by weight, based on the total weight of the preparation. 5 If vitamin E and/or derivatives thereof are the antioxidant or the antioxidants, it is advantageous to choose their respective concentrations from the range from 0.001 to 10% by weight, based on the total weight of the formulation. If vitamin A or vitamin A derivatives, or carotenes or derivatives thereof are the 10 antioxidant or the antioxidants, it is advantageous to choose their respective concentrations from the range from 0.001 to 10% by weight, based on the total weight of the formulation. It is particularly advantageous when the cosmetic preparations according to the present 15 invention comprise cosmetic or dermatological active ingredients, preferred active ingredients being antioxidants which can protect the skin against oxidative stress. Further advantageous active ingredients for the purposes of the present invention are natural active ingredients and/or derivatives thereof, such as, for example, a-lipoic acid, 20 phytoene, D-biotin, coenzyme Q10, a-glucosylrutin, camitine, camosine, natural and/or synthetic isoflavonoids, creatine, taurine and/or l-alanine, and 8-hexadecene-1,16 dicarboxylic acid (dioic acid, CAS number 20701-68-2; provisional INCI name Octadecenedioic acid). 25 Formulations according to the invention which comprise, for example, known antiwrinkle active ingredients, such as flavone glycosides (in particular a-glycosylrutin), coenzyme Q10, vitamin E and/or derivatives and the like are particularly advantageously suitable for the prophylaxis and treatment of cosmetic or dermatological changes in the skin, as arise, for example, during skin aging (such as, for example, dryness, roughness and 30 formation of dryness wrinkles, itching, reduced refatting (e.g. after washing), visible vascular dilations (telangiectases, cuperosis), flaccidity and formation of wrinkles and lines, local hyperpigmentation, hypopigmentation and incorrect pigmentation (e.g. age spots), increased susceptibility to mechanical stress (e.g. cracking) and the like). In addition, they are advantageously suitable to counter the appearance of dry or rough 35 skin.

19 The water phase of the preparations according to the invention can advantageously comprise customary cosmetic auxiliaries, such as, for example, alcohols, in particular those of low carbon number, preferably ethanol and/or isopropanol, diols or polyols of low carbon number, and ethers thereof, preferably propylene glycol, glycerol, butylene glycol, 5 ethylene glycol, ethylene glycol monoethyl or monobutyl ether, propylene glycol monomethyl, monoethyl or monobutyl ether, diethylene glycol monomethyl or monoethyl ether and analogous products, polymers, foam stabilizers, electrolytes, and in particular one or more thickeners, which may advantageously be chosen from the group consisting of silicon dioxide, aluminum silicates, polysaccharides or derivatives thereof, e.g. 10 hyaluronic acid, xanthan gum, hydroxypropylmethylcellulose, particularly advantageously from the group of polyacrylates, preferably a polyacrylate from the group of so-called Carbopois [from Bf. Goodrich], for example carbopol grades 980, 981, 1382, 2984, 5984, ETD 2020, ETD 2050, Ultrez 10, in each case individually or in combination. 15 In addition, the preparations according to the invention can advantageously also comprise self-tanning substances, such as, for example, dihydroxyacetone and/or melanin derivatives in concentrations of from 1% by weight to 8% by weight, based on the total weight of the preparation. 20 In addition, the preparations according to the invention can advantageously also comprise repellents for protection against flies, ticks and spiders and the like. For example, N,N-diethyl-3-methylbenzamide (trade name: Metadelphene, "DEET"), dimethyl phthalate (trade name: Palatinol M, DMP) and in particular ethyl 3-(N-n-butyl-N acetylamino)propionate (available under the trade name lnsekt Repellent 3535 from 25 Merck) are advantageous. The repellents can either be used individually or in combination. Moisturizers is the term used to refer to substances or mixtures of substances which impart to cosmetic or dermatological preparations the property, following application or 30 distribution on the surface of the skin, of reducing moisture release by the horny layer (also called trans-epidermal water loss (TEWL)) and/or of positively influencing hydration of the horny layer. Advantageous moisturizers for the purposes of the present invention are, for example, 35 glycerol, lactic acid and/or lactates, in particular sodium lactate, butylene glycol, propylene glycol, biosaccharide gum-1, glycine soya, ethylhexyloxyglycerol, pyrrolidone- 20 carboxylic acid and urea. In addition, it is particularly advantageous to use polymeric moisturizers from the group of water-soluble and/or water-swellable and/or water-gelable polysaccharides. Hyaluronic acid, chitosan and/or a fucose-rich polysaccharide, which is filed in the Chemical Abstracts under the registry number 178463-23-5 and which is 5 available, for example, under the name Fucogelo 1000 from SOLABIA S.A., for example, are particularly advantageous. Moisturizers can advantageously also be used as anti wrinkle active ingredients for the prophylaxis and treatment of cosmetic or dermatological changes in the skin, as arise, for example, during skin aging. 10 The cosmetic or dermatological preparations according to the invention can also advantageously, but not necessarily, comprise fillers, which, for example, further improve the sensory and cosmetic properties of the formulations and, for example, bring about or enhance a velvety or silky feel on the skin. Advantageous fillers for the purposes of the present invention are starch and starch derivatives (such as, for example, tapioca starch, 15 distarch phosphate, aluminum or sodium starch octenylsuccinate and the like), pigments which have neither a primarily UV filter effect nor a coloring effect (such as, for example, boron nitride etc.) and/or AerosilsO (CAS No. 7631-86-9). The oil phase of the formulations according to the invention is advantageously chosen 20 from the group of polar oils, for example 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 with a chain length of from 8 to 24, in particular 12 to 18, carbon atoms. The fatty acid triglycerides can, for example, be chosen advantageously from the group of synthetic or semisynthetic and natural oils, 25 such as, for example, cocoglyceride, olive oil, sunflower oil, soybean 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. Also advantageous according to the invention are, for example, natural waxes of animal 30 and vegetable origin, such as, for example, beeswax and other insect waxes, and berry wax, shea butter and/or lanolin (wool wax). For the purposes of the present invention, further advantageous polar oil components can also advantageously be chosen from the group of esters of saturated and/or 35 unsaturated, branched and/or unbranched alkanecarboxylic acids of chain length from 3 to 30 carbon atoms and saturated and/or unsaturated, branched and/or unbranched 21 alcohols of chain length 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 of chain length from 3 to 30 carbon atoms.

In addition, the oil phase can likewise advantageously also comprise nonpolar oils, for 35 example those which are chosen from the group of branched and unbranched hydrocarbons and hydrocarbon waxes, in particular mineral oil, vaseline (petrolatum), 22 paraffin oil, squalane and squalene, polyolefins, hydrogenated polyisobutenes and isohexadecane. Among the polyolefins, polydecenes are the preferred substances. The oil phase can also advantageously have a content of cyclic or linear silicone oils or 5 consist entirely of such oils, although it is preferred to use an additional content of other oil phase components apart from the silicone oil or the silicone oils. Silicone oils are high molecular weight synthetic polymeric compounds in which silicon atoms are joined in a chain-like and/or reticular manner via oxygen atoms and the 10 remaining valences of the silicon are saturated by hydrocarbon radicals (in most cases methyl, less often ethyl, propyl, phenyl groups etc.). Systematically, the silicone oils are referred to as polyorganosiloxanes. The methyl-substituted polyorganosiloxanes, which are the most important compounds of this group in terms of amount and are characterized by the following structural formula 15 CH r CH 3

Goldschmidt. However, other silicone oils can also be used advantageously for the purposes of the present invention, for example cetyldimethicone, hexamethylcyclotrisiloxane, polydimethylsiloxane, poly(methylphenylsiloxane).

Siloxane elastomers present in the form of spherical powders which are advantageous 25 according to the invention are those with the INCI name Dimethicone/Vinyl Dimethicone Crosspolymer, for example that available from DOW CORNING under the trade names DOW CORNING 9506 Powder. It is particularly preferred when the siloxane elastomer is used in combination with oils 30 from hydrocarbons of animal and/or vegetable origin, synthetic oils, synthetic esters, synthetic ethers or mixtures thereof. It is very particularly preferred when the siloxane elastomer is used in combination with unbranched silicone oils which are liquid or pasty at room temperature or cyclic silicone 35 oils or mixtures thereof. Organopolysiloxane elastomers with the INCI name Dimethicone/Polysilicone-11, very particularly the Gransil grades obtainable from Grant 24 Industries Inc. GCM, GCM-5, DMG-6, CSE gel, PM-gel, LTX, ININ gel, AM-18 gel and/or DMCM-5, are particularly advantageous. It is very extremely preferred when the siloxane elastomer is used in the form of a gel of 5 siloxane elastomer and a lipid phase where the content of the siloxane elastomer in the gel is 1 to 80% by weight, preferably 0.1 to 60% by weight, in each case based on the total weight of the gel.

The cosmetic and dermatological preparations according to the invention can comprise 15 dyes and/or color pigments, particularly when they are in the form of decorative cosmetics. The dyes and color pigments can be chosen from the corresponding positive list in the Cosmetics Directive or the EC list of cosmetic colorants. In most cases, they are identical to dyes approved for foods. Advantageous color pigments are, for example, titanium dioxide, mica, iron oxides (e.g. Fe 2 03, Fe 3

O

4 , FeO(OH)) and/or tin oxide. 20 Advantageous dyes are, for example, carmine, Prussian blue, chromium oxide green, ultramarine blue and/or manganese violet. It is particularly advantageous to choose the dyes and/or the color pigments from the Rowe Colour Index, 3r Edition, Society of Dyers and Colourists, Bradford, England, 1971. 25 if the formulations according to the invention are in the form of products which are used on the face, it is favorable to choose one or more substances from the following group as the dye: 2,4-dihydroxyazobenzene, 1-(2'-chloro-4'-nitro-1'-phenylazo)-2-hydroxy naphthalene, Ceres red, 2 -(sulfo-l-naphthylazo)-1-naphthol-4-sulfonic acid, calcium salt of 2-hydroxy-1,2'-azonaphthalene-l'-sulfonic acid, calcium and barium salts of 1-(2-sulfo 30 4 -methyl-l-phenylazo)-2-naphthylcarboxylic acid, calcium salt of 1-(2-sulfo-1 naphthylazo)-2-hydroxynaphthalene-3-carboxylic acid, aluminum salt of 1-(4-sulfo-1 phenylazo)-2-naphthol-6-sulfonic acid, aluminum salt of 1-(4-sulfo-1l-naphthylazo)-2 naphthol-3,6-disulfonic acid, 1-(4-sulfo-1l-naphthylazo)-2-naphthol-6,8-disulfonic acid, aluminum salt of 4-(4-sulfo-1l-phenylazo)-1-( 4 -sulfophenyl)-5-hydroxypyrazolone-3 35 carboxylic acid, aluminum and zirconium salts of 4 ,5-dibromofluorescein, aluminum and zirconium salts of 2 ,4,5,7-tetrabromofluorescein, 3',4',5',6'-tetrachloro-2,4,5,7- 25 tetrabromofluorescein and its aluminum salt, aluminum salt of 2,4,5,7 tetraiodofluorescein, aluminum salt of quinophthalonedisulfonic acid, aluminum salt of indigodisulfonic acid, red and black iron oxide (CIN: 77 491 (red) and 77499 (black)), iron oxide hydrate (CIN: 77492), manganese ammonium diphosphate and titanium 5 dioxide. Also advantageous are oil-soluble natural dyes, such as, for example, paprika extracts, j3-carotene or cochineal. 10 Also advantageous for the purposes of the present invention are formulations with a content of pearlescent pigments. Preference is given in particular to the types of pearlescent pigments listed below: 1. Natural pearlescent pigments, such as, for example, * "pearl essence" (guanine/hypoxanthin mixed crystals from fish scales) and 15 * "mother-of-pearl" (ground mussel shells) 2. Monocrystalline pearlescent pigments, such as, for example, bismuth oxychloride (BiOCI) 3. Layer-substrate pigments: e.g. mica/metal oxide 20 Bases for pearlescent pigments are, for example, pulverulent pigments or castor oil dispersions of bismuth oxychloride and/or titanium dioxide, and bismuth oxychloride and/or titanium dioxide on mica. The luster pigment listed under CIN 77163, for example, is particularly advantageous. 25 Also advantageous are, for example, the following types of pearlescent pigments based on mica/metal oxide: Group Coating/layer thickness Color Silver-white pearlescent pigments TiO 2 :40-60 nm Silver Interference pigments TiO 2 : 60-80 nm Yellow Ti0 2 : 80-100 nm Red TiO 2 : 100-140 nm Blue TiO2:120-160 nm Green Color lustre pigments Fe 2 03 Bronze Fe 2 0 3 Copper 26 Fe 2

Pearlescent pigments which are advantageous for the purposes of the present invention are obtainable by numerous methods known per se. For example, other substrates apart from mica can be coated with further metal oxides, such as, for example, silica and the like. SiO 2 particles coated with, for example, TiO 2 and Fe 2 03 ("ronaspheres"), which are 10 sold by Merck and are particularly suitable for the optical reduction of fine lines, are advantageous. It can, moreover, be advantageous to dispense completely with a substrate such as mica. Particular preference is given to iron pearlescent pigments prepared without the 15 use of mica. Such pigments are obtainable, for example, under the trade name Sicopearl Kupfer 1000 from BASF. In addition, also particularly advantageous are effect pigments which are obtainable under the trade name Metasomes Standard/Glitter in various colors (yellow, red, green, 20 blue) from Flora Tech. The glitter particles are present here in mixtures with various auxiliaries and dyes (such as, for example, the dyes with the Colour Index (Cl) numbers 19140, 77007, 77289, 77491). The dyes and pigments may be present either individually or in a mixture, and can be 25 mutually coated with one another, different coating thicknesses generally giving rise to different color effects. The total amount of dyes and color-imparting pigments is advantageously chosen from the range from, for example, 0.1% by weight to 30% by 27 weight, preferably from 0.5 to 15% by weight, in particular from 1.0 to 10% by weight, in each case based on the total weight of the preparations. For the purposes of the present invention, it is also advantageous to provide cosmetic 5 and dermatological preparations whose main purpose is not protection against sunlight, but which nevertheless have a content of further UV protection substances. Thus, for example, UV-A and/or UV-B filter substances are usually incorporated into daycreams or make-up products. UV protection substances, like antioxidants and, if desired, preservatives, also constitute effective protection of the preparations themselves against 10 spoilage. Also favorable are cosmetic and dermatological preparations in the form of a sunscreen. Accordingly, for the purposes of the present invention, the preparations preferably comprise at least one further UV-A, UV-B and/or broadband filter substance. The 15 formulations can, but do not necessarily, optionally also comprise one or more organic and/or inorganic pigments as UV filter substances, which may be present in the water phase and/or the oil phase. In addition, the preparations according to the present invention can also advantageously 20 be in the form of so-called oil-free cosmetic or dermatological emulsions, which comprise a water phase and at least one UV filter substance which is liquid at room temperature as a further phase, and which may particularly advantageously also be free from further oil components. 25 For the purposes of the present invention, particularly advantageous UV filter substances which are liquid at room temperature are homomenthyl salicylate (INCI: Homosalate), 2 ethylhexyl 2-cyano-3,3-diphenylacrylate (INCI: Octocrylene), 2-ethylhexyl 2 hydroxybenzoate (2-ethylhexyl salicylate, octyl salicylate, INCI: Ethylhexyl Salicylate) and esters of cinnamic acid, preferably 2-ethylhexyl 4-methoxycinnamate (INCI: Ethylhexyl 30 Methoxycinnamate) and isopentyl 4-methoxycinnamate (INCI: Isoamyl p Methoxycinnamate), 3

(AI

2 0 3 ), cerium (e.g. Ce 2 03), mixed oxides of the corresponding metals, and mixtures of such oxides, and also the sulfate of barium (BaSO 4 ). 5 For the purposes of the present invention, the pigments may advantageously also be used in the form of commercially available oily or aqueous predispersions. Dispersion auxiliaries and/or solubility promoters may advantageously be added to these predispersions. 10 According to the invention, the pigments may advantageously be surface-treated ("coated"), the intention being to form or retain, for example, a hydrophilic, amphiphilic or hydrophobic character. This surface treatment can consist in providing the pigments with a thin hydrophilic and/or hydrophobic inorganic and/or organic coat by methods known per se. For the purposes of the present invention, the various surface coatings may also 15 comprise water. Inorganic surface coatings for the purposes of the present invention may consist of aluminum oxide (AI 2 0 3 ), aluminum hydroxide AI(OH) 3 , or aluminum oxide hydrate (also: alumina, CAS No.: 1333-84-2), sodium hexametaphosphate (NaPO 3

)
