Definitions

  • the present invention relates to novel flavones, preparations and mixtures containing flavones, their preparation and use.

  • Another approach is to protect the skin from environmental influences that lead to permanent damage and thus aging of the skin.
  • the idea is to intervene preventively and thereby delay the aging process.
  • An example of this are the UV filters already mentioned, which avoid or at least reduce damage to the skin by absorption of certain wavelength ranges. While in UV filters, the damaging event, the UV radiation is shielded from the skin, one tries in another way, the natural defense or repair mechanisms of the skin

  • a number of undesirable side effects occur, such as sunburn or premature aging and wrinkling.
  • the wavelength range of 280 to 400 nm is the wavelength range of 280 to 400 nm.

  • tanning may also age, promote the triggering of an erythematous reaction, or increase this response in certain people, or even trigger phototoxic or photoallergic and irritative reactions.
  • Skin damage is caused not only by sunlight, but also by other external influences, such as cold or heat. Furthermore, the skin is subject to natural aging, which causes wrinkles and relieves the elasticity of the skin.
  • Structural change e.g. change their color and / or lose their effectiveness.
  • Antioxidants are compounds that inhibit or prevent undesirable changes in the substances to be protected due to oxidative effects, such as oxidative effects. Fields of application are, for example, in plastics and rubber for protection against aging; in fats for protection against rancidity, in oils, animal feed, automotive gasoline and jet fuels for protection against gumming, in transformer and turbine oil against sludge formation, in flavorings against odor deterioration.
  • Effective antioxidants include phenols substituted by sterically hindering groups, Hydroquinones, catechols and aromatics. Amines and their metal complexes. According to Römpp, the effect of the antioxidants is usually that they act as radical scavengers for the free radicals which occur during the autoxidation.
