Definitions

  • the present invention relates to cosmetic or dermatological (light protection) formulations containing stilbene and / or its derivatives and the use of stilbene and / or its derivatives to make cosmetic and dermatological formulations visible, in particular cosmetic and dermatological light protection formulations on the skin , especially with the help of light activation.
  • ⁇ 3rd degree cell damage deep cell damage occurs, the body reacts with fever, the epidermis is rejected over a large area.
  • the 2nd and 3rd degrees are also called solar dermatitis.
  • the formation of the erythema depends on the wavelength.
  • the erythema range of the UV-B is between 280 nm and 320 nm.
  • UV-A rays About 90% of the ultraviolet radiation reaching the earth consists of UV-A rays with a wavelength between 320 nm and 400 nm. While the UV-B radiation varies greatly depending on numerous factors (e.g. time of year and time of day) or latitude), the UV-A radiation remains relatively constant day by day, regardless of the time of year, time of day or geographical factors. At the same time, the majority of UV-A radiation penetrates the living epidermis, while around 70% of UV-B rays are retained by the horny layer.
  • UV-A radiation has only a negligible biological effect and that UV-B rays are accordingly responsible for most of the light damage to human skin.
  • UV-B radiation is far more dangerous than UV-B radiation in terms of triggering photodynamic, especially phototoxic reactions and chronic changes in the skin.
  • the damaging influence of UV-B radiation can also be intensified by UV-A radiation.
  • the sunburn or the light erythema are the acute manifestations of the effect of light.
  • particularly strongly exposed areas of the skin face, neck, hands
  • the most noticeable chronic light damage to the skin is actinic or senile elastosis. Macroscopically, it manifests itself in thickening and coarsening of the skin, wrinkling, loss of elasticity, the appearance of yellowish shimmering deposits and irregular pigment accumulations.
  • the epidermis becomes thin in places and shows warty growths, the dermis loses its elasticity and tension, the water retention capacity is reduced.
  • Chronic light damage that occurs as a late consequence also includes malignant melanoma and, in the last stage, actinic keratosis.
  • the benefit of a sunscreen preparation is to extend the amount of time that a consumer can stay in the sun without causing light damage.
  • the filter effect should be adapted in particular for the UV-B range to the individual sensitivity of the consumer and the intensity of solar radiation.
  • the weakening of the intensity of the incident light and thus the effectiveness of a sun protection formulation depend, among other things, on the layer thickness of the applied filter substance. With increasing layer thickness, the effectiveness of a sunscreen also increases. Particularly in the case of low-viscosity preparations such as oils or alcoholic solutions, it is therefore necessary to also increase the viscosity of the formulation and thus the achievable layer thickness on the skin from a certain limit concentration of filter substance. In addition, it is only possible to a limited extent to increase the sun protection factor by increasing the concentration of the UV filter substance.
  • the layer thickness achieved with a special base is a very important criterion in light protection.
  • the sun protection factor increases in the order of oil ⁇ alcoholic solution ⁇ liquid emulsion ⁇ cream ⁇ paste.
  • Another important parameter in this context is the adhesiveness or water resistance of the formulations on the skin.
  • Most sunscreens are used near the water or during sports activities (sweating).
  • a waterproof solar Protective agents can protect the user from sunburn not only during bathing but also after bathing, provided it is not washed off too much.
  • the prior art knows a variety of different light protection formulations with the most diverse light protection factors and application properties.
  • the disadvantage of these customary sunscreens is that after applying the cream, the user can neither see whether he has covered all parts of the body exposed to the radiation with a protective layer, nor whether the skin has been adequately covered. H. whether the layer thickness was chosen sufficiently.
  • Another disadvantage is that the user cannot keep track of how the layer thickness of the sunscreen changes, for example due to contact with water or mechanical stresses such as drying, etc., and accordingly when a new creaming has become necessary.
  • a high level of protection of the preparations is of particular importance, especially for children's and baby products, since children are particularly susceptible to sunburn due to the low light swell (thickening of the horny layer) and the reduced level of self-protection and also often play for hours on or in the water.
  • the object of the present invention was accordingly to remedy the disadvantages of the prior art and to find ways to visualize cosmetic and dermatological sunscreen formulations on the skin and thus to facilitate the application of a uniform film to the skin.
  • DE-100 34 332-A1 describes the use of effect pigments with an average particle size of 15 ⁇ m to 200 ⁇ m for the visualization of cosmetic and dermatological formulations on the skin.
  • DE-100 35 512-A1 also describes the use of dyes to make cosmetic and dermatological light protection formulations visible on the skin.
  • this prior art could not point the way to the present invention.
  • both EP-94 05 B1 and EP 1 136 059-A2 describe colored sun protection emulsions which are distinguished by the fact that the color essentially fades when the sun protection emulsion dries after it has been distributed on the skin and / or rubbed into the skin.

  • the present invention furthermore relates to the use of stilbene and / or its derivatives for the visualization of cosmetic and dermatological light protection formulations on the skin.

  • the formulations leave on the skin, both for the user himself and for third parties, such as. B. parents, easily recognizable which areas of the skin are already covered with a protective layer and where (or again) creaming is required.
  • the cosmetic is usually visualized directly with the eye, for example by the user viewing the area of skin in question using a contrast enhancer.
  • the substances according to the invention absorb visible and / or UV light and then emit light whose wavelength is longer than that of the absorbed light. So they show an effective fluorescence in a longer-wave range.
