Abstract

An aqueous-alcoholic cosmetic and/or dermatological preparation contains a UV-A filter comprising a hydroxybenzophenone and/or a benzoxazole derivative. An independent claim is also included for production of the preparation by dissolving the UV-A filter(s) in alcohol and then adding the other components.

Description

The The present invention relates to aqueous-alcoholic cosmetic and dermatological preparations, in particular they are cosmetic and dermatological formulations with increased UV-A protection performance.

The damaging effect of the ultraviolet part of solar radiation on the skin is well known. Depending on their respective wavelength, the rays have different effects on the organ skin:
The so-called UV-C radiation with a wavelength between 100 and 280 nm is absorbed by the ozone layer of the earth's atmosphere and is accordingly not found in the solar spectrum. It is therefore physiologically meaningless when sunbathing.

Of the so-called UV-B range is between 290 nm and 320 nm. UV-B rays are essential for the long-lasting tanning responsible for the skin but at the same time an erythema, a simple sunburn or even cause more or less severe burns. Also chronic Photodamage, Photodermatoses and herpes solaris can be caused by UV-B radiation become.

you has been wrong for a long time assumed that the long-wave UV-A radiation with a wavelength between 320 nm and 400 nm only a negligible has biological activity and that accordingly the UV-B rays for the most photodamage responsible for the human skin. Meanwhile, though Numerous studies have shown that UV-A radiation in terms of on the trigger pho-dynamic, especially phototoxic reactions and chronic changes the skin far more dangerous as UV-B radiation is. Also, the damaging influence of UV-B radiation reinforced by UV-A radiation become.

So is it u. a. proved that itself the UV-A radiation is sufficient under normal everyday conditions to damage the collagen and elastin fibers within a short time, the for the Structure and firmness of the skin are essential. This leads to chronic light-induced skin changes - the skin "ages" prematurely Appearance of light aged skin, for example, includes Wrinkles and wrinkles as well as an irregular, furrowed Relief. Furthermore, can the areas affected by photodamage have irregular pigmentation exhibit. Also the formation of brown spots, keratoses and even Carcinomas or malignant melanoma is possible. One through the everyday UV exposure Prematurely aged skin is also characterized by a lower activity Langerhans cells and a mild, chronic inflammation.

Approximately There is 90% of the ultraviolet radiation reaching the earth from UV-A rays. While the UV-B radiation depending varies greatly depending on numerous factors (eg year and time of day) or latitude), the UV-A radiation remains independent of Yearly or daily or geographical factors day by day relative constant. At the same time, most of the UV-A radiation penetrates into the living epidermis while About 70% of the UV-B rays are retained by the horny layer become.

The newer findings about the effect of the UV-A rays on the skin have led to the precautions For this Radiation range now increased Devotes attention. Virtually no sunscreen product comes more without effective UV-A filter effect, pure UV-B filter preparations are rare.

At the Apply a sunscreen to the skin, the ultraviolet rays are attenuated by two effects: on the one hand by reflection and scattering of the rays on the surface of pulverulent solids (physical light protection) and on the other by absorption chemical substances (chemical light protection). Whichever Wavelength range A distinction is made between UV-B filters (absorption range 280 to 320 nm), UV-A filters (absorption range 320 to 400 nm) and broadband filtering (absorbance range 290 to about 380 nm).

To the Protection against UV-B radiation, numerous compounds are known wherein the absorption maximum as possible should be around 308 nm, since here the highest erythema efficacy of the Solar radiation is present. Typical UV-B filters are z. B. derivatives of the 3-benzylidene camphor, 4-aminobenzoic acid, the cinnamic acid, salicylic acid, Benzophenone and 2-phenylbenzimidazole.

Also for protection against UV-A radiation, some compounds are known, in particular Diben zoylmethanderivate. However, dibenzoylmethane derivatives are generally not photostable, which is why cosmetic or dermatological preparations containing this substance should advantageously also contain certain UV stabilizers. Other 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.

Next The pure UV-A or UV-B filters have substances, both Cover areas. For example, this group of broadband filters unsymmetrically substituted s-triazine compounds, such as. B. the 2,4-bis - {[4- (2-ethyl-hexyloxy) -2-hydroxy] phenyl} -6- (4-methoxyphenyl) -1,3,5-triazine (INCI: bis-ethylhexyloxylphenol methoxyphenyl triazine), certain Benzophenones, such as. For example, 2-hydroxy-4-methoxy-benzophenone (INCI: Benzophenones 3) or 2,2'-methylenebis (6- (2H-benzotriazol-2-yl) -4- (1,1,3,3-tetramethylbutyl) -phenol) (INCI: Methylene bis-benzotriazolyl tetramethyleneebutylphenol).

in the general is the light absorption behavior of sunscreen filter substances very well known and documented, especially in most industrialized countries positive lists for the Use of such substances exist, which are quite strict standards to the Create documentation. As for the characterization of a filter substance not only the location of the absorption maximum, but above all the Absorption range is important, absorption spectra of each substance added. For the dosage of the substances in the finished formulations can the Extinction values but at most provide guidance, because of interactions with ingredients of the skin or the skin surface yourself can uncertainties occur. Furthermore, it is usually difficult to estimate in advance how evenly and in which layer thickness the filter substance in and on the horny layer the skin is distributed.

to exam the UV-A protection performance is usually the IPD method used (IPD - immediate pigment darkening). This is - similar to the determination of the sun protection factor - a value determined, which indicates how much longer with the sunscreen protected Skin can be irradiated with UV-A radiation until the same pigmentation occurs as with the unprotected Skin.

The Use concentration of known sunscreen present sunscreen filter substances, which show a high filtering effect, especially in the UV-A range, is however often - straight in combination with others to solve Substances - limited. It therefore causes some formulation difficulties, higher To achieve sun protection factors or UV-A protection performance.

There Sunscreen filter substances are usually expensive and there some sunscreens also difficult in higher concentrations to be incorporated into cosmetic or dermatological preparations are, it was an object of the invention, to simple and inexpensive Way to get to preparations, which at unusually low Concentrations of conventional UV-A sunscreen filters nevertheless an acceptable or even achieve high UV-A protection performance.

A special form of sunscreen filter formulations provide the aqueous-alcoholic preparations because this is a pleasant cooling Have an effect on the skin and leave no greasy-oily feeling on the skin. Also, by the application of aqueous-alcoholic Lichschutzzubereitungen the phenomenon observed in many sunscreens Clinging of sand and other (dirt) particles on the skin effectively suppressed become. Furthermore, the risk of causing "Mallorca acne" is significantly reduced. Last but not least, the production of aqueous-alcoholic preparations in Comparison to the production of emulsions particularly simple, energy-saving and cost-effective.

It is preparing big though Problems of incorporating UV sunscreen filter substances into aqueous-alcoholic preparations. Most of these compounds are lipophilic and only slightly soluble in water, so that so far only small amounts of filter substances in have the preparations incorporated. This applies in particular to UV-A filter substances.

It Therefore, the object of the present invention, the shortcomings of Prior art to eliminate.

Surprisingly, the problem is solved by aqueous-alcoholic cosmetic and / or dermatolo gische preparations containing at least one UV-A filter from the group of hydroxybenzophenones and / or benzoxazole derivatives.
