Description

The present invention relates to cosmetic and / or dermatological Light protection formulations which have a particularly advantageous sensor system. At the same time, the formulation has a synergistic effect on the achieved SPFs. The formulations are suitable for protecting the skin and / or the Hair from UV radiation and are applied by application to the skin or the Hair.

The harmful 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 that is less than 290 nm is from the ozone layer in the earth's atmosphere absorbed and therefore has no physiological meaning. Against cause Rays in the range between 290 nm and 320 nm, the so-called UV-B range Erythema, a simple sunburn or even more or less severe Burns. As a maximum of the erythema effectiveness of sunlight, the narrower Range around 308 nm specified.

To protect against UV-B radiation, numerous compounds are known in which it are, for example, derivatives of 3-benzylidene camphor, 4-aminobenzoic acid, cinnamic acid, salicylic acid and benzophenone.

It has long been erroneously assumed that long-wave UV-A radiation with a wavelength between 320 nm and 400 nm only a negligible one has biological effects. However, numerous studies have now shown that UV-A radiation with a view to triggering photodynamic, especially phototoxic Reactions and chronic changes in the skin are far more dangerous than UV-B Radiation is. The damaging influence of UV-B radiation from UV-A Radiation to be amplified.

So it is u. a. proved that even the UV-A radiation under normal Everyday conditions are sufficient to quickly reduce the collagen and elastin fibers damage that are essential for the structure and firmness of the skin. This leads to chronic light-related skin changes - the skin "ages" prematurely. The clinical appearance of light-aged skin is part of it for example folds and wrinkles as well as an irregular, furrowed relief. Further the areas affected by light-induced skin aging can become irregular Have pigmentation. Even the formation of brown spots, keratoses and even Carcinoma or malignant melanoma is possible. One through everyday UV exposure prematurely aged skin is also characterized by a lower activity of the Langerhans cells and a mild, chronic inflammation.

About 90% of the ultraviolet radiation reaching the earth consists of UV-A Rays. While the UV-B radiation is strong depending on numerous factors varies (e.g. time of year and day or latitude), the UV-A radiation remains Relative to day and day or geographical factors regardless of the season constant. At the same time, the major part of UV-A radiation penetrates the living Epidermis, while about 70% of UV-B rays come from the horny layer be held back.

It is therefore of fundamental importance that cosmetic and dermatological Light protection preparations against both UV-B and UV-A radiation provide adequate protection.

Inorganic micropigments are also suitable as light stabilizers. These work in such a way that they reflect the UVA and UVB rays on the surface of the skin. The particle sizes of the pigments are chosen so that the individual particles are no longer perceptible to the eye. For example, pigments based on metal oxides and / or other metal compounds which are sparingly soluble or insoluble in water are used, in particular the oxides of titanium (TiO ₂ ), zinc (ZnO), iron (e.g. Fe ₂ O ₃ ), zirconium (ZrO ₂ ), Silicon (SiO ₂ ), manganese (e.g. MnO), aluminum (Al ₂ O ₃ ), cerium (e.g. Ce ₂ O ₃ ), mixed oxides of the corresponding metals, mixtures of such oxides and the sulfate of Bariums (BaSO ₄ ). The inorganic pigments are often used in hydrophobic form, ie they are treated to be water-repellent on the surface. This surface treatment can consist in that the pigments are provided with a thin hydrophobic layer by methods known per se.

The use of solid elastomeric polyorganosiloxanes or organopolysiloxanes, hereinafter referred to as siloxane elastomers, in cosmetic preparations is known per se and has become increasingly important in recent years. These substances found


in addition to use in cosmetics, use in food and feed, pharmaceuticals, impregnating agents, lubricants and so on. Siloxal elastomers are partially or completely cross-linked and mostly have a three-dimensional structure. They can be obtained by a reaction of vinyl-terminated polymethylsiloxane and methylhydrodimenthylsiloxane
or also by reaction of hydroxy-terminated dimethylpolysiloxane and trimethylsiloxy-terminated methylpolysiloxane:

These siloxane elastomers are used, for example, to adjust the rheological Properties of a preparation used. Such are described Siloxane elastomers, for example in European Patent 295886 and U.S. Patent 5,266,321, which discloses the use of these substances in facial cleansers or oily makeup products. In these Writings also describe the nature of the siloxane elastomers in more detail. The use of the Siloxane elastomers are used in cosmetic preparations in particular because of their pleasant sensory properties, the resulting products are considered described as velvety, powdery and / or matting. In addition, they have stabilizing Effects on high oil formulations with low water content of at most 5% by weight. This often arises when formulating the products mentioned above Problem that the siloxane elastomers with other commonly used components are incompatible, which leads to unsatisfactory long-term stability of the products.

The object of the present invention was cosmetic and / or dermatological To provide sunscreen preparations which have the disadvantages of the prior art Do not have technology and especially high sun protection factors, good Long-term storage stability, pleasant sensory properties and improved Have water resistance.
