Definitions

  • Cosmetic and dermatological light protection formulations containing benzotriazoles and benzoxazole derivatives containing benzotriazoles and benzoxazole derivatives
  • the present invention relates to cosmetic and dermatological light protection preparations, in particular it relates to cosmetic and dermatological formulations with increased UV-A protection.
  • the damaging effect of the ultraviolet part of solar radiation on the skin is generally known. Depending on their wavelength, the rays have different effects on the skin organ:
  • UV-C radiation with a wavelength between 100 and 280 nm is absorbed by the ozone layer in the earth's atmosphere and is therefore not found in the solar spectrum. It is therefore of no physiological importance when sunbathing.
  • UV-B range is between 290 nm and 320 nm. UV-B rays are essential for long-lasting tanning of the skin, but can also cause erythema, simple sunburn or even more or less severe burns. Chronic light damage, photodermatosis and herpes solaris can also be caused by UV-B radiation.
  • UV-A radiation with a wavelength between 320 nm and 400 nm has only a negligible biological effect and that UV-B rays are accordingly responsible for most light damage to human skin.
  • UV-A radiation is pho- todynamic, especially phototoxic reactions and chronic changes in the skin is far more dangerous than UV-B radiation.
  • the damaging influence of UV-B radiation can also be intensified by UV-A radiation.
  • UV-A radiation About 90% of the ultraviolet radiation reaching the earth consists of UV-A rays. While UV-B radiation varies greatly depending on numerous factors (eg time of year and time of day or latitude), UV-A radiation remains relatively constant day by day, irrespective of the time of year, 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.
  • the ultraviolet rays can be attenuated by two effects: on the one hand by reflection and scattering of the rays on the surface of powdery solids (physical light protection) and on the other hand by absorption of chemical substances (chemical light protection). It differs depending on which wavelength range is absorbed between UV-B filters (absorption range 280 to 320 nm), UV-A filters (absorption range 320 to 400 nm) and broadband filters (absorption range 290 to approx. 380 nm).
  • UV-B filters are e.g. B. derivatives of 3-benzylidene camphor, 4-aminobenzoic acid, cinnamic acid, salicylic acid, benzophenone and also 2-phenylbenzimidazole.
  • UV-A filter substances are certain water-soluble, sulfonated UV filter substances, such as. B. phenylene-1,4-bis (2-benzimidazyl) -3,3'-5,5'-tetrasulfonic acid and its salts.
  • This group of broadband filters includes, for example, asymmetrically substituted s-triazine compounds, such as. B. 2,4-bis - ⁇ [4- (2-ethylhexyloxy) -2-hydroxy] phenyl ⁇ -6- (4-methoxyphenyl) -1,3,5-triazine (INCI: bis -Ethylhexyloxylphenol methoxy-phenyl triazine), certain benzophenones, such as. B.
  • the light absorption behavior of light protection filter substances is very well known and documented, especially since in most industrialized countries there are positive lists for the use of such substances, which apply very strict standards to the documentation. Since not only the position of the absorption maximum, but above all the absorption range is important for the characterization of a filter substance, absorption spectra of each substance are recorded. For the dosage of the substances in the finished formulations, however, the extinction values can at best be an orientation offer assistance because interactions with ingredients of the skin or the surface of the skin itself can cause uncertainties. Furthermore, it is generally difficult to estimate in advance how evenly and in what layer thickness the filter substance is distributed in and on the horny layer of the skin.
  • the preparations according to the invention are extremely satisfactory preparations, which are not limited to a restricted selection of raw materials are. Accordingly, they are particularly suitable to serve as the basis for forms of preparation with a variety of uses.
  • the preparations according to the invention show very good sensory and cosmetic properties, such as, for example, the distributability on the skin or the ability to be absorbed into the skin, and are also notable for very good light protection effectiveness, an extremely high UV-A protection performance and excellent skin compatibility at the same time excellent skin care data.
  • the invention therefore also relates to cosmetic or dermatological preparations which have a light protection effect, characterized in that they contain synergistic combinations of substances
  • (b) contain at least one benzoxazole derivative, the UV protection, in particular the UV-A protection, of these preparations being increased disproportionately.
