Description

The The present invention relates to cosmetic and dermatological compositions to protect the skin and hair against UV radiation.

The Skin damaging effect of the ultraviolet part of solar radiation is known. The UV radiation in the range between 290 nm and 320 nm, the so-called UV-B-range, can become an erythema, a simple sunburn or even more or less severe burns as acute manifestations. As a maximum of Erythema activity of sunlight becomes the narrower area 308 nm indicated.

you For a long time, it has wrongly assumed that the long-wave UV-A radiation with a wavelength between 320 nm and 400 nm has only a negligible biological effect. Meanwhile, however, numerous studies have shown that UV-A radiation with regard to the triggering of photodynamic, especially phototoxic reactions and chronic changes the skin, far more dangerous than UV-B radiation. Also, the damaging influence of UV-B radiation can be due UV-A radiation to be amplified. So it is u. a. proven that even the UV-A radiation under normal everyday conditions sufficient to make the collagen and elastin fibers within a short time harm to the structure and strength the skin are essential. This is what happens chronic light-induced skin lesions - the Skin "ages" prematurely. To the clinical appearance the light-aged skin, for example, belong Wrinkles and wrinkles as well as an irregular, furrowed relief. Furthermore, the light-induced Skin aging affected areas an irregular Have pigmentation. Also the formation of brown spots, keratoses and even carcinomas or malignant melanoma is possible. A prematurely aged by the everyday UV exposure Skin is also characterized by a lower activity Langerhans cells and a mild, chronic inflammation out.

Approximately There is 90% of the ultraviolet radiation reaching the earth from UV-A rays. While the UV-B radiation is dependent varies greatly depending on numerous factors (eg year and time of day) or latitude), the UV-A radiation remains independent of annual and daytime or geographical factors day relatively constant for the day. At the same time, the vast majority penetrates Part of the UV-A radiation entering the living epidermis while About 70% of the UV-B rays are retained by the horny layer become.

It is therefore of fundamental importance that cosmetic and dermatological sunscreen compositions against both UVB and as well as against UV-A radiation provide adequate protection. These are in the prior art already a variety of cosmetic compositions have been developed which contain at least one UV filter substance.

at The UV filter substances are liquid at room temperature or crystalline substances which are capable of ultraviolet Absorb radiation and the absorbed energy in the form of longer-wave Radiation, z. B. heat, again. One differentiates UV-A filter and UV-B filter, depending on which wavelength range the absorption maximum of the filter is.

organic UV filters in the necessary for a high sun protection factor Frequently, quantities can only be handled with great difficulty so incorporate into cosmetic carriers that long-term stable Compositions having pleasant, in particular non-sticky, properties to be obtained.

to Production of particularly powerful sunscreen compositions It is based on oil-water emulsions (O / W or W / O) advantageous if both in the oil phase and in the Water phase at least one organic UV filter is included. Because UV filters in large economic areas, such as US, EU, Japan or Australia, substances subject to authorization is the cosmetic specialist in the manufacture of new sunscreen compositions bound to a relatively limited range of approved UV filters. A particularly preferred water-soluble organic UV filter this is 2-phenylbenzimidazole-5-sulfonic acid. This connection however, tends to crystallize upon prolonged storage, what the SPF (Sun Protection Factor, SPF) of the entire Composition drops drastically.

tasks

The compositions of the prior art are further improved. In particular, compositions containing combinations of UV filter substances or other active ingredients sometimes have formulation difficulties with regard to the use concentrations, which is the result make good UV protection performance difficult.

One Another disadvantage of the prior art is that usual Sunscreen formulations often a sticky skin feel leave.

task The present invention was to provide sunscreen compositions provide a high level of protection against the above various adverse effects of radiation in the UV-A and UV-B range, especially solar radiation, provide and at the same time have improved sensory properties. The invention Compositions should also have good skin care properties, especially effectiveness against signs of skin aging (eg Wrinkling, loss of elasticity), as well as a pleasant Skin sensation and easy spreading on the skin exhibit.

Farther should the compositions of the invention with the lowest possible concentration of organic UV filters provide the highest possible sun protection factor (SPF) achieve. Especially preferred is an SPF of at least 30, most preferably at least 40.

Farther should compositions of the invention provided a long-term and storage stable SPF whose initially measured SPF will be after several weeks Storage decreases as little as possible.

A Another object of the present invention was to provide sunscreen compositions, the at least one water-soluble organic UV filter to provide in storage stable form.

s-triazine derivatives

aufweisen, mit dem obligatorischen O/W-Emulgatorsystem, umfassend mindestens ein Salz von C_12-20-Alkylphosphat und mindestens ein C_14-20-Mono- oder Diacylglycerid, im obligatorischen pH-Bereich teilweise geringere SPF-Werte und geringere Lagerstabilitäten erzielt werden konnten als beispielsweise mit Polysilicone-15.Surprisingly, it was found that with oil-soluble organic UV filter substances based on s-triazine derivatives, the following structural motif

In A preferred embodiment is the oil-in-water emulsions according to the invention therefore, free of s-triazine derivatives having the above structural motif TRIAZIN-GROUND have.

s-triazine derivatives having the structure motif TRIAZIN-GRUND above are known in the art, for example from EP 775698 . EP 878469 and EP 1027881 , With regard to the C ₃ axis of the triazine basic body of these compounds, both symmetrical substitution and unsymmetrical substitution are conceivable.

In this sense symmetrically substituted s-triazines have three identical substituents R ¹ , R ² and R ³ , while asymmetrically substituted s-triazine derivatives consequently have different substituents, whereby the C ₃ symmetry is destroyed. For the purposes of the present invention, "unsymmetrical" is always understood to be asymmetrical with respect to the C ₃ axis of the triazine base, unless something else is expressly mentioned.

With respect to the C ₃ axis of the triazine parent symmetrical triazine derivatives are, for example, those of the general formula TRIAZIN-GRUND with R ¹ = R ² = R ³ = -NH-Phe-COOR, with Phe = phenyl radical in which the substituents - NH and -COOR are in para position to each other. Corresponding symmetrical triazine derivatives are 4,4 ', 4 "- (1,3,5-triazine-2,4,6-triyltriimino) tris-benzoic acid tris (alkyl ester), in particular 4,4', 4" - (1,3,5-triazine-2,4,6-triyltriimino) -tris-benzoic acid tris (2-ethylhexyl) [INCI: ethylhexyl Triazone, formerly octyl Triazone], which as a single substance by BASF under the trade name Uvinul ^® T 150, but is also available in various commercial UV filter blends.

R₄ und R₅ können aus der Gruppe der verzweigten und unverzweigten Alkylgruppen von 1 bis 18 Kohlenstoffatomen gewählt. Auch können die Alkylgruppen wiederum mit Silyloxygruppen substituiert sein.Unsymmetrical triazine derivatives are, for example, those which are known in EP 775698 are disclosed:

R ₄ and R ₅ can be selected from the group of branched and unbranched alkyl groups of 1 to 18 carbon atoms. Also, the alkyl groups may in turn be substituted with silyloxy groups.
