Definitions
- Cosmetic or dermatological preparations containing folic acid, volatile and nonvolatile silicones containing folic acid, volatile and nonvolatile silicones
- the present invention relates to cosmetic or dermatological preparations containing folic acid, volatile and nonvolatile silicones
- folic acid and / or derivatives thereof for the preparation of cosmetic or dermatological preparations for the prophylaxis of damage to the skin's own DNA and / or for the repair of already occurred damage to the skin's own DNA.
- the skin is exposed to a variety of environmental factors that can lead to their damage.
- lipids and proteins especially the DNA is affected.
- UVC region The damaging effect of the ultraviolet part of solar radiation on the skin is well known. While rays having a wavelength smaller than 290 nm (the so-called UVC region) are absorbed by the ozone layer in the earth's atmosphere, rays in the range between 290 nm and 320 nm, the so-called UVB region, cause erythema simple sunburn or even more or less severe burns.
- UVA range it is important to have available filter substances, since its rays can cause reactions in photosensitive skin. It has been proven that UVA radiation too Damage to the elastic and collagenous fibers of the connective tissue results, 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 amplified by UVA radiation.
- Skin cells in particular receive a high proportion of DNA damage as a result of frequent UV exposure and therefore require particularly efficient and efficient repair systems.
- Only efficient, proprietary DNA repair systems are able to quickly repair damage that can prevent skin alteration and early onset of skin aging. Efficient DNA repair thus contributes significantly to maintaining a healthy, vital skin. Stimulation and support of skin-own repair systems by cosmetic-dermatological ingredients are therefore very important.
- DNA replication required in view of the large number of nucleotides that have to be copied per cell division is guaranteed, on the one hand, by the specificity of the DNA polymerases involved in replication (replicases) and, on the other hand, by their additional exonuclease activity: They catalyze the excision of inappropriate nucleotides and their replacement by the correct ones immediately after the new synthesis.
- the damage caused by chemical action (by mutagens, some of which can intervene between two superimposed base pairs of the double helix) as well as the radiation-induced changes (eg two superimposed thymine residues can dimerize) help repair enzymes (including: Endonucleases, polymerases, ligases) that cut out and replace inappropriate nucleotides again from the DNA.
- repair enzymes including: Endonucleases, polymerases, ligases
- Some of these repair systems are inducible, i. H. they are synthesized only when needed. The question of which strand contains the original information and which was wrongly synthesized is apparently decided by the repair enzyme on the basis of the state of methylation.
- Exposure to environmental factors causes damage to the DNA molecules of the body's cells, which, however, can be remedied by cellular DNA repair mechanisms. First of all, the DNA damage is detected and then the damage is repaired.
- environmental factors e.g., ultraviolet radiation, chemical and physical factors
- Object of the present invention was therefore to remedy the evils of the prior art remedy.
- active ingredients and preparations should be provided which should ensure a reliable prophylaxis of damage to the skin's own DNA and / or in a particular embodiment should be used to repair damage already occurred to the skin's own DNA.
- Folic acid has the following structure:
- Folic acid occurs in liver, kidney, yeast, fungi, cereals and green leaves, predominantly as a conjugate with poly- ⁇ -L-glutamic acid (pteroylpolyglutamic acids). It has been discovered as a growth substance for various microorganisms and has a vitamin character for the human organism. Adult human needs are about 200 ⁇ g per day of bioavailable folate.
- H 2 folate 7,8-dihydrofolic acid
- FH 2 7,8-dihydrofolic acid
- H 2 folate is produced in plants and some microorganisms via several intermediates from guanosine 5'-triphosphate (guanosine phosphates) and converts to (6S) -5,6,7,8-tetrahydrofolic acid with the aid of dihydrofolate reductase Physiologically active form of folic acid.
- 7,8-Dihydrofolic acid has the following chemical structure:
- derivatives of folic acid is to be understood in particular as meaning the abovementioned dihydrofolic acid and the tetrahydrofolic acid.
- folic acid Since folic acid is water-soluble, it does not stay on the skin long enough to work optimally after morning use / sweating. Film formers or very greasy emulsions make this possible, but are z.T. difficult to spread and leave an unpleasant skin feeling.
- folic acid and / or derivatives thereof have a high potential for repairing damaged DNA. Furthermore, folic acid and / or its derivatives provide effective prophylaxis against DNA damage, especially those caused by UV radiation.
- the combination of nonvolatile and volatile silicone oils (preferably dimethicones and cyclomethicones) in an emulsion enables the folic acid remains on the skin long enough.
- the cosmetic preparation is very well distributed and has a light, pleasant skin feel.
- the preferred embodiment contains more volatile silicone oil (cyclomethicone) than non-volatile silicone oil (dimethicone).
- compositions which are advantageous according to the invention are those in which the weight ratios of folic acid and / or derivatives thereof to nonvolatile silicone oils are chosen to be volatile silicone oils (A: B: C) such as a: b: c, where a, b and c independently of one another are rational numbers from 1 to 5, preferably from 1 to 3 represent.

- Non-volatile is a silicone oil that stays on the skin or lips for several hours. It has a vapor pressure at room temperature of less than 0.02 mm Hg (2.66 Pa). A volatile silicone oil evaporates from the skin or lips within an hour. It has a vapor pressure at room temperature which is between 0.02 mmHg and 300 mm Hg (13 Pa-12000 Pa), preferably between 0.1 mmHg and 90 mm Hg (2.66 Pa-40,000 Pa).
