Definitions
- the present invention relates to cosmetic or dermatological preparations containing 9-retinal and / or 9-retinal-alkanolamine Schiff base of the structural formula
- R ROH, branched or unbranched alkanols.
- R ROH, branched or unbranched alkanols.
- the use of preparations containing 9-retinal and / or 9-retinal-alkanolamine Schiff base leads to the induction and intensification of the tanning mechanisms of the skin and to the intensification of the hair color.
- UVC range rays with a wavelength shorter than 290 nm
- UVB range rays in the range between 290 nm and 320 nm, the so-called UVB range, cause erythema simple sunburn or even more or less severe burns on the skin.
- 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, because of that Rays can cause damage. It has been shown that UVA radiation damages the elastic and collagen fibers of the connective tissue, which causes the skin to age prematurely, and that it is to be seen as the cause of numerous phototoxic and photoallergic reactions. The damaging influence of UVB radiation can be intensified by UV-A radiation.
- UVA radiation can also cause skin damage by u. a. the skin's own keratin or elastin is damaged. This reduces the skin's elasticity and water retention capacity, i.e. the skin becomes less supple and tends to wrinkle. This type of wrinkling is also known as light-related skin aging. The strikingly high incidence of skin cancer in areas exposed to strong sunlight shows that damage to the genetic information in the cells is apparently also caused by sunlight.
- UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products interfere with the skin's metabolism.
- UV radiation also belongs to ionizing radiation. There is therefore a risk that ionic species also develop when exposed to UV, which in turn can then oxidatively intervene in the biochemical processes.
- the pigmentation of the human skin is essentially caused by the presence of melanin.
- the degree of bleeding as well as the nature and thickness of the stratum corneum and other skin layers make skin tones of practically white (with reduced filling or in the absence of blood vessels) or yellowish over light brown-reddish, bluish to brown different shades and finally almost black appear.
- the individual skin regions show different depths of color tint due to different amounts of melanin.
- melanin protects the skin from penetrating UV radiation.
- the number of melanin granules produced in the melanocytes determines whether the skin is light or dark.
- melanin can also be found in the stratum spinosum and even in the stratum corneum. It weakens the UV radiation by up to approx. 90% before it reaches the corium.
- melanocytes contain melanosomes, in which the melanin is formed. When stimulated by UV radiation, among other things, melanin is increasingly formed. This is ultimately transported via the living layers of the epidermis (keratinocytes) into the homolayer (comeocytes) and causes the more or less pronounced brown to brown-black skin color.
- keratinocytes the epidermis
- comeocytes the homolayer
- brown to brown-black skin color keratinocytes
- Melanin is formed as the final stage of an oxidative process in which tyrosine, with the help of the enzyme tyrosinase, is converted into brown to brown-black eumelanins (DHICA and DHI melanin) or with the participation of sulfur-containing compounds to reddish pheomelanin.
- DHICA and DHI melanin brown to brown-black eumelanins
- DHICA and DHI melanin are produced via the common intermediate stages dopaquinone and dopachrome.
- the latter is implemented, partly with the participation of further enzymes, either in indole-5,6-quinone carboxylic acid or in indole-5,6-quinone, from which the two eumelanins mentioned arise.
- the formation of phaeomelanin occurs, among other things, via the intermediates dopaquinone and cysteinyldopa.
- melanin In addition to various functions of the skin's own melanin (also "detoxification'V connection of toxic substances / pharmaceuticals, etc.), the function of melanin as a natural UV filter to protect against damaging UV rays and the antioxidant function of melanin as protection against reactive oxygen species (oxidative Stress), which can occur, among other things, from the sun's rays, is very important for the skin, including in relation to homeostasis, avoidance of skin aging, avoidance of sunburn, etc. This should not just be a cosmetic benefit in terms of increased tanning due to the increased melanin synthesis in the skin after topical application of compounds which increase the melanogenesis, but also provide additional protection through the various protective functions of melanin.
- oxidative Stress reactive oxygen species
- Skin type I never tans, always gets a sunburn.
- Skin type II hardly tans, easily gets sunburned.
- Skin type III tans well on average.
- Skin type IV tans lightly and persistently, almost never gets sunburned.
- Skin type V dark, often almost black skin, never gets sunburned.
- make-up or make-up preparations The easiest way to give your skin a brown hue is to apply appropriately colored make-up or make-up preparations. However, only those parts of the body that are covered by the colored preparations are of course stained. With the help of washable make-up preparations, a light skin tint can be achieved (e.g. extracts from fresh green walnut shells, henna).
- a disadvantage of the make-up is therefore the time-consuming procedure of applying. Another disadvantage is that they rub off heavily on textiles such as shirt collars or blouses.
- the different dyes can have different allergenic potency and can even be irritating to the skin.
- carotene is stored in the subcutaneous fatty tissue, the skin gradually turns orange to yellow-brown.
- the staining can also be done by chemical modification of the skin's skin layer with so-called self-tanning preparations.
- the most important active ingredient is dihydroxyacetone (DHA).
- DHA dihydroxyacetone
- Dihydroxyacetone can be called ketotriose and reacts as a reducing sugar with the amino acids of the skin or the free amino and imino groups of keratin via a series of intermediates in the sense of a Maillard reaction to brown-colored substances, so-called melanoids, which occasionally also melanoidins to be named.
- a particular disadvantage of tanning with dihydroxyacetone is that, in contrast to "sun-tanned" skin, the tanned skin is not protected against sunburn.
- Another disadvantage of dihydroxyacetone is that it, especially under the influence of ultraviolet radiation, albeit in mostly releases small amounts of formaldehyde, so there was an urgent need to find ways in which the decomposition of dihydroxyacetone can be effectively countered.
- An object of the present invention is to find alternatives to DHA as a self-tanning agent which do not have any disadvantageous properties as are known from DHA.
- Another type of artificial tanning which is also completely independent of UV light, can be brought about by the hormones, which are also released in the body as a result of (natural) UV radiation and ultimately stimulate the melanocytes to synthesize melanin.
- proopiomelanocortin POMC
- aMSH proopiomelanocortin
- synthetic variants such as NDP
- these hormones can generally bring about a tan, their use in cosmetics is forbidden, since they are clearly pharmacological acting substances (hormones), which should not be widely used without medical indication.
- the object of the present invention was therefore to remedy the disadvantages of the prior art.
- the structure of all these hairs is roughly similar: the central hair mark (from epithelial cells with eosinophilic granules of the trichohyaline granule), surrounded by the hair cortex (from horny cells; contains pigments) and the cuticle (cuticle pili; coreless epidermal layer) and of layers of the epithelial and connective tissue sheath.
- the hair is divided into the hair shaft protruding from the skin and the oblique hair root reaching into the subcutis, the layers of which correspond approximately to those of the epidermis.
- the thickened lower end of the root, the hair bulb sits on a vascular connective tissue cone, the hair papilla, protruding into it (both as a hair floor).
- Melanin is responsible for the personal hair color. Melanin is formed in the melanocytes, cells that are associated with the keratinocytes of the hair bulb
- melanocytes contain melanosomes, in which the melanin is formed. This will go over the long Dendrites of the melanocytes are transferred into the keratinocytes of the precortical matrix and produce the more or less pronounced blonde to brown-black hair color.
- Melanin is formed as the final stage of an oxidative process in which tyrosine is converted into brown to brown-black eumelanins (DHICA and DHI melanin) or with the participation of sulfur-containing compounds to reddish pheomelanin with the help of the enzyme tyrosinase.
- DHICA and DHI melanin are produced via the common intermediate stages dopaquinone and dopachrome.
- phaeomelanin occurs, among other things, via the intermediates dopaquinone and cysteinyldopa. Cysteine is also necessary if the phaeomelanin is to be created for blonde and reddish hair.
- Eumelanin is the black-brown pigment. It is mainly about the depth of color of the hair. In brown and black hair it occurs in clearly recognizable granules.
- Phaeomelanin is the red pigment. It is responsible for light blonde, blonde and red hair. The structure of this melanin is much finer and smaller. The different hair colors result from the different proportions of the melanin types:
- Blond hair contains little eumelanin and a lot of phaeomelanin.
- Red hair also has little eumelanin and a lot of phaeomelanin.
- the pigment formation process can only proceed if sufficient tyrosinase is available. This enzyme is formed less frequently with increasing age. This gradually leads to gray hair. The reason: with little tyrosinase, less and less tyrosine is formed. The production of melanin also decreases. The missing melanin is replaced by the storage of air bubbles. The hair appears gray. This process is usually insidious. It begins at the temples and then extends to the entire hair on the head. Then it hits the beard and eyebrows. Finally, all of the body's hair is gray.
- gray hair is called canities.
- canities There are several ways of graying. Premature graying, from the age of 20, is also called Canities praecox.
- Symptoms of canities, or symptomatic graying of the hair can have various causes. This includes:
- Pernicious anemia (vitamin B deficiency anemia), severe endocrinological disorders, e.g. B. in thyroid diseases. acute, febrile diseases,
- the cosmetic industry uses lead acetate in some countries, which is toxic and is therefore prohibited in the European Cosmetics Regulation.
- This lead acetate is preferably applied to the hair as a solution and remains there for a long time without being washed off.
- dyeing keratin fibers e.g. B. hair, wool or fur
- direct dyes or oxidation dyes which are formed by oxidative coupling of one or more developer components with one another or with one or more coupler components, are used. Coupler and developer components are also referred to as oxidation dye precursors.
- Primary aromatic amines with a further free or substituted hydroxyl or amino group in the para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and derivatives thereof are usually used as developer components used.
- Special representatives are, for example, p-phenylenediamine, p-toluenediamine, 2,4,5,6-tetraaminopyrimidine, p-aminophenol, N, N-bis (2-hydroxyethyl) -p-phenylenediamine, 2- (2,5-diaminophenyl ) -ethanol, 2- (2,5-diaminophenoxy) -ethanol, 1-phenyl-3-carboxyamido-4-amino-pyrazolon-5, 4-amino-3-methylphenol, 2-aminomethyl-4-aminophenol, 2- Hydroxy-methyl-4-aminophenol, 2-hydroxy-4,5,6-triaminopyrimidine, 2,4-dihydroxy-5,6-diaminopyrimidine and 2,5,6-triamino-4-hydroxypyrimidine.
- M-Phenylenediamine derivatives, naphthols, resorcinol and resorcinol derivatives, pyrazolones and m-aminophenols are generally used as coupler components.
- Suitable coupler substances are, in particular, ⁇ -naphthol, 1, 5-, 2,7- and 1, 7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monomethyl ether, m-phenylenediamine, 2 , 4-diaminophenoxyethanol, 1-phenyl-3-methylpyrazolon-5, 2,4-dichloro-3-aminophenol, 1, 3-bis (2,4-diaminophenoxy) propane, 2-chlororesorcinol, 4-chlororesorcinol , 2-chloro-6-methyl-3-aminophenol, 2-methylresorcinol and 5-methylresorcinol.
- Oxidation dye precursors sometimes have a sensitizing effect on people with sensitive skin. Direct dyes are applied under gentler conditions, but their disadvantage is that the dyeings often have inadequate fastness properties.
- the object of the present invention is to improve the independent melanin production of the hair, but without coloring agents and in particular oxidizing agents such. B. H 2 O 2 to be instructed.
- the agents must have no or only a very low sensitization potential.
- the object of the present invention was therefore to remedy the disadvantages of the prior art.
