The present invention relates to sunscreen compositions for application to the skin containing certain polyurethanes, as well as the use of these polyurethanes for the manufacture of sunscreen products.

Long tanned leather is synonymous with attractive, healthy, athletic, and successful person. To achieve this, people expose their skin to sunlight. However, the sun's rays have on the skin harmful effects, because they are depending on wavelengths penetrate the skin at different depths. Shortwave radiation in the UV-b (wavelength: 280-320 nm) reaches the upper layers of the skin. Radiation in the UV-b region causes sunburn and is responsible for the increased risk of skin cancer. Long-wave UV-A (wavelength: 320-400 nm) penetrates the layers of skin that are more deeply. It causes damage to collagen and elastin fibers, which are of key importance for the structure and strength of the skin. In addition, it leads to premature aging of the skin (the formation of deep and fine wrinkles, non-uniform skin texture etc). To protect the skin from solar radiation was developed substances with the functions of filters, protection from radiation (UV-a and UV-b filters contained in the list form is approved for use, t is anyone as Annex 7 to the cosmetic regulations), used in cosmetic and dermatological compositions.

Sunscreen products are often used outdoors during a vacation or leisure time at sea, or during exercise, when the body is in contact with water or sweat. There is therefore a need to develop water-resistant and/or resistant to sweat sunscreen compositions. The production of such products is made possible thanks to the use of certain technologies, such as, for example, emulsions of water in oil (W/M) or through the use of a hydrophobic film-forming substances, such as, for example, the alkylated polyvinylpyrrolidone.

The use of polyurethanes in sunscreen compositions described in the prior art. In the German patent DE 10223693 describes the use of polyurethane, which is formed when politicoeconomic 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl-1-isocyanate and polyhydric alcohols, glycerides, complex hydroxyamino derived silicones and/or amines. In the European patent EP 1214929 describes the use of film-forming, water-soluble or capable of dispergirujutsja polyurethane in water to improve the water resistance of cosmetic or dermatological compositions containing at least one UV filter. In U.S. patent US2003044364 describes the use of polyurethanes to improve the water resistance of sunscreen compositions.

However, sunscreen products according to the issues of the prior art have the following drawbacks:

- Water emulsion of the type water-in-oil (W/M) heavily distributed and also left after the application of unpleasant, wax-like feeling on the skin.

- The use of a hydrophobic film-forming substances radically change sensation on the skin from sunscreen compositions. These compositions are in the process of distribution on the skin often form pellets (the so-called effect of clumping) and leave on the skin a feeling of stickiness, oiliness and greasiness.

Thus, at the heart of this invention lies in the task of developing a cosmetic or dermatological sunscreen composition, which has excellent water resistance. However, at the same time not neglecting other important characteristics, such as ease of application, comfort, lack of sensation on the skin sticky and oily, and the lack of education of pellets.

Unexpectedly, this task is solved by the use of certain polyurethanes or their aqueous dispersions, which can be obtained by reacting one or more water-insoluble, are not able to dispergirujutsja in water polyurethane prepolymers A)containing isocyanate functional the group, at least one or more compounds containing amidofunctional group.
