Definitions

  • the present invention relates to cosmetic and dermatological preparations with an effective content of physiologically compatible combinations of active ingredients.
  • the present invention relates to cosmetic preparations with effective protection against harmful oxidation processes in the skin, but also to protect cosmetic preparations themselves or to protect the constituents of cosmetic preparations from harmful oxidation processes.
  • the present invention also relates to antioxidants, preferably those which are used in skin-care cosmetic or dermatological preparations.
  • the invention also relates to cosmetic and dermatological preparations containing such antioxidants.
  • the present invention relates to cosmetic and dermatological preparations for the prophylaxis and treatment of cosmetic or dermatological skin changes such as skin aging, in particular skin aging caused by oxidative processes.
  • the present invention further relates to active ingredients and preparations containing such active ingredients for the cosmetic and dermatological treatment or prophylaxis of erythematous, inflammatory, allergic or autoimmune reactive phenomena, in particular dermatoses.
  • the present invention also relates to active ingredient combinations and preparations which are used for the prophylaxis and treatment of light-sensitive skin, in particular of photodermatoses.
  • UVC range rays with a wavelength smaller than 290 nm
  • UVB- Area rays in the range between 290 nm and 320 nm, the so-called UVB- Area, an erythema, a simple sunburn or even more or less severe burns.
  • the narrower range around 308 nm is given as a maximum of the erythema effectiveness of sunlight.
  • UVA range It is also important to have filter substances available for the range between about 320 nm and about 400 nm, the so-called UVA range, since its rays can cause reactions in photosensitive skin. It has been proven that UVA radiation leads to damage to the elastic and collagenous fibers of the connective tissue, which causes the skin to age prematurely, and that it can be seen as the cause of numerous phototoxic and photoallergic reactions. The damaging influence of UVB radiation can be intensified by UVA radiation.
  • UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products intervene in the skin's metabolism.
  • Such photochemical reaction products are predominantly radical compounds, for example hydroxy radicals.
  • Undefined free radical photo products which arise in the skin itself, can show uncontrolled secondary reactions due to their high reactivity.
  • singlet oxygen a non-radical excited state of the oxygen molecule, can also occur when exposed to UV radiation, as can short-lived epoxides and many others.
  • Singlet oxygen stands out from the normally present triplet oxygen (more radical Ground state) by increased reactivity.
  • UV radiation also counts as ionizing radiation. There is therefore a risk that ionic species will also be formed when exposed to UV, which in turn are able to intervene oxidatively in the biochemical processes.
  • antioxidants and / or radical scavengers can be incorporated into the cosmetic or dermatological formulations.
  • vitamin E a substance with a known antioxidant effect, in light protection formulations, but here too the effect achieved remains far below that which was hoped for.
  • the object of the invention was therefore also to create cosmetic, dermatological and pharmaceutical active ingredients and preparations and light protection formulations which are used for the prophylaxis and treatment of light-sensitive skin, in particular photo dermatoses, preferably PLD.
  • Erythematous skin symptoms also occur as side effects of certain skin diseases or irregularities. For example, the typical skin rash is usually more or less reddened when acne appears.
  • Antioxidants are mainly used as protective substances against spoilage of the preparations containing them. Nevertheless, it is known that undesirable oxidation processes can also occur in human and animal skin. Such processes play an essential role in skin aging.
  • skin Diseases Associated with Oxidative Damage in "Oxidative Stress in Dermatology", p. 323 ff. (Marcel Decker Inc., New York, Basel, Hong Kong, editors: Jürgen Fuchs, Frankfurt, and Lester Packer, Berkeley / California), oxidative damage to the skin and its more detailed causes are listed.
  • oxidizing hair coloring the dye chromophore is formed by the reaction of precursors (phenols, aminophenols, more rarely also diamines) and bases (mostly p-phenylenediamine) with the oxidizing agent, mostly hydrogen peroxide. Hydrogen peroxide concentrations around 6% are commonly used.
  • the hydrogen peroxide also has a bleaching effect.
  • oxidatively dyed human hair similar to bleached hair, microscopic holes can be detected in the places where melanin granules are present.
  • the oxidizing agent hydrogen peroxide not only reacts with the dye precursors, but also with the hair substance and can cause damage to the hair under certain circumstances.
  • Antioxidants are substances which prevent oxidation processes or which prevent the auto-oxidation of fats containing unsaturated compounds.
  • Antioxidants which are also used in the field of cosmetics and pharmacy, are, for example, ⁇ -tocopherol, in particular in the form of ⁇ -tocopheryl acetate, sesamol, gallic acid derivatives, butylhydroxyanisole and butylhydroxytoluene.
  • Antioxidants and / or radical scavengers can also be incorporated into cosmetic formulations for the purpose of preventing such reactions.
  • antioxidants and radical scavengers are known.
  • US Patents 4,144,325 and 4,248,861 as well as numerous other documents suggest It has been decided to use vitamin E, a substance with a known antioxidant effect, in sunscreen formulations, but here too the effect achieved remains far below the hoped-for effect.
  • One object of the present invention was to eliminate the disadvantages of the prior art.
  • active ingredients or preparations containing such active ingredients should be made available, if they are used, damage to the skin and / or hair due to oxidative influence can at least be reduced, if not completely prevented.
  • Another object of the present invention was to provide cosmetic preparations which, before or after treatment of the hair with hair coloring preparations, even those with a content of strong oxidizing agents such as hydrogen peroxide, counteract their damaging oxidizing effect.
  • active ingredients and preparations containing such active ingredients should be made available for the cosmetic and dermatological treatment and / or prophylaxis of erythematous, inflammatory, allergic or autoimmune reactive phenomena, in particular dermatoses, but also the appearance of "stinging".
  • active ingredient combinations comprising a) one or more ubiquinols and b) short-chain hyaluronic acid (45-55 kDa) or cosmetic or dermatological preparations containing such active ingredient combinations or the use of such active ingredient combinations as an antioxidant and / or as free radical scavengers, in particular in cosmetic or dermatological preparations, represent the solution to these problems and remedy the disadvantages of the prior art.
  • Ubiquinols are characterized by the following chemical structure and act as antioxidants:
  • n 10 predominates (ubidecarenol), which according to the invention is the preferred ubiquinol. Due to the redox character of ubiquinone and ubiquinol, only the reduced form, ubiquinol, can act as an antioxidant (Fig. 1).
  • ubiquinols The cosmetic use of ubiquinols is known per se, for example from WO 2017/045034, DE 4228871 and other publications.
  • Hyaluronic acid is a polysaccharide derivative, which is characterized by the following structural element:
  • Hyaluronic acid is a glycosaminoglycan found in connective tissue, vitreous humor, umbilical cord and synovial fluid in the joints. Hyaluronic acid is particularly abundant in the early embryonic stages and acts here Cell migrations with, because their loose structure and a high water content shield the cells expressing them on their surface from each other and thus enable their free mobility. Hyaluronic acid is involved in wound healing
  • Hyaluronic acid is a high molecular compound with molecular weights between 40,000 and several million.
  • Experiments have shown that when the antioxidant ubiquinol is combined with long-chain hyaluronic acid (1800-2500 kDa), the antioxidant effect of ubiquinol is unfortunately weakened or canceled (FIG. 2).
