The present invention relates to cosmetic and / or dermatological preparations containing

• a) biotin,
• b) at least one ubiquinone and / or a derivative thereof
• c) at least one cyclodextrin and / or a derivative thereof in addition to other cosmetic auxiliaries and active ingredients, and their use.

The skin is the largest organ in humans. Among its many functions (for example for heat regulation and as a sensory organ) is the barrier function that prevents the skin (and ultimately the entire organism) from drying out probably most important. At the same time, the skin acts as a protective device against penetration and the absorption of substances coming from outside. This barrier function is effected through the epidermis, which is the outermost layer opposite the actual protective cover of the environment. With about a tenth of the total thickness, it is also the thinnest layer of skin.

The epidermis is a stratified tissue in which the outer layer, the horny layer (Stratum corneum), which is the important part for the barrier function. It will be in Worn out contact with the environment and is therefore in a constant Renewal process, whereby fine scales are continuously released to the outside cornified cell and lipid material is reproduced from the inside.

The skin model of Elias (P. M. Elias, Structure and Function of the Stratum Corneum Permeability Barrier, Drug Dev. Res. 13, 1988, 97-105) describes the horny layer as a two-component system, similar to one Brick wall (brick mortar model). In this model they correspond Horn cells (corneocytes) the bricks, the complex composite Lipid membrane in the intercellular spaces corresponds to the mortar. This system represents in essentially a physical barrier against hydrophilic substances, but can due to its narrow and multilayered structure, it is equally lipophilic Substances are difficult to pass. The special structure of the horny layer protects on the one hand the skin and on the other hand stabilizes its own flexibility through bonding a defined amount of water.

Mechanical loads, such as pressure, impact or shear forces, can be astonished by the horny layer alone or in combination with the deeper layers of skin can be caught. Greater pressure, torsional or shear forces are connected to the deeper layers of the skin by the intermeshing of the epidermis with the corium passed.

Cosmetic skin care means primarily that the natural Function of the skin as a barrier against environmental influences (e.g. dirt, chemicals, Microorganisms) and against the loss of the body's own substances (e.g. water, natural Fats, electrolytes) is strengthened or restored.

If this function is disturbed, the absorption of toxic or allergenic substances may increase Substances or for infestation of microorganisms and as a result too toxic or allergic skin reactions are coming.

The aim of skin care is also to reduce the fat and fat caused by daily washing Compensate for skin water loss. This is especially important when the natural Regeneration capacity is not sufficient. In addition, skin care products are said to exist Protect environmental influences, especially from the sun and wind, and skin aging delay.

• a) Trockenheit, Rauhigkeit und Ausbildung von Trockenheitsfältchen,
• b) Juckreiz und
• c) verminderte Rückfettung durch Talgdrüsen (z. B. nach Waschen).

The chronological skin aging is e.g. B. caused by endogenous, genetically determined factors. In the epidermis and dermis it occurs due to aging e.g. B. the following structural damage and malfunctions, which may also fall under the term "senile xerosis":

• a) dryness, roughness and formation of dry wrinkles,
• b) itching and
• c) Reduced regreasing by sebum glands (e.g. after washing).

• a) Sichtbare Gefäßerweiterungen (Teleangiektasien, Cuperosis);
• b) Schlaffheit und Ausbildung von Falten;
• c) lokale Hyper-, Hypo- und Fehlpigmentierungen (z. B. Altersflecken) und
• d) vergrößerte Anfälligkeit gegenüber mechanischem Stress (z. B. Rissigkeit).

Exogenous factors, such as UV light and chemical pollutants, can be cumulatively effective and e.g. B. accelerate or complement the endogenous aging processes. In the epidermis and dermis, it occurs in particular due to exogenous factors such. B. the following structural damage and functional disorders in the skin, which go beyond the extent and quality of the damage with chronological aging:

• a) Visible vasodilation (telangiectasia, cuperosis);
• b) flaccidity and wrinkling;
• c) local hyper, hypo and incorrect pigmentations (e.g. age spots) and
• d) increased susceptibility to mechanical stress (e.g. cracking).

The present invention particularly relates to products for the care of Environmental pollutants such as B. UV light, ozone, cigarette smoke stressed skin, and Treatment of the consequential damage of light aging, in particular that under a) to g) phenomena listed.

Products for the care of aged skin are known per se. They contain e.g. B. Retinoids (Vitamin A acid and / or its derivatives) or vitamin A and / or its derivatives. However, their effect on structural damage is limited in scope. About that In addition, there are considerable difficulties in product development, the active ingredients in sufficient to stabilize against oxidative decay. The use of vitamin In addition, A-acidic products often cause severe erythematous Skin irritation. Retinoids can therefore only be used in low concentrations.

The active ingredient biotin (vitamin H) belongs to the group of bio-growth substances that regulate the embryonic or plasmatic growth of the cells and is an indispensable factor for the multiplication of yeast and other microorganisms. In the human organism, it has proven to be an active ingredient necessary for the normal function of the skin, vitamin H (Beyer, Walter, Textbook of Organic Chemistry, 22nd edition, S. Hirzel Verlag). Biotin is a chiral molecule with three asymmetric carbon atoms and has the following structure:

Natural biotin is clockwise and can be synthesized from D-mannose.

Recently biotin has been used increasingly in cosmetics (e.g. DE 42 42 876). In general, however, the effectiveness of biotin is rather moderate, as the Connection is poorly absorbed by the skin.

Ubiquinones are a group of substances that are attached to their quinone ring Have bound isoprene units in a chain. Ubiquinones act in the biological, mitochondal oxidation as an electron carrier and play an important role in the energy metabolism of the cells.

The ubiquinones are known from the literature (e.g. Beyer, Walter, textbook of the Organic Chemistry, S. Hirzel-Verlag, Stuttgart, 22nd edition). They are also called Mitochinone or Coenzyme Q called. The number of isoprene units in the Side chain is given with n in the name coenzyme Q-n, where n is a whole Number means. Coenzymes from n = 0 to n = 12 are known. Most common are however n = 6-10.

Ubiquinones have long been used in cosmetic preparations as antioxidants to protect substances sensitive to oxidation. For example, WO 95/26181 describes ubiquinones in topical preparations. WO 95/26180 describes the combination of ubiquinones and retinols as skin care products. The disadvantage in the prior art is also the poor bioavailability of the compounds, which usually remain on the skin with the preparation.

Cyclodextrins (cycloamyloses, cycloglucans) are termed cyclic Oligosaccharides consisting of α-1,4 linked glucose building blocks. Usually are six to eight glucose units (α-γ-cyclodextrin) linked together. Cyclodextrins are obtained when Bacillus macerans acts on starch. she have a hydrophobic interior and a hydrophilic exterior. cyclodextrins and their derivatives can form inclusion complexes due to their structure. You are for Microencapsulation of active ingredients suitable (e.g. as a protective covering sensitive molecules in cosmetic and pharmaceutical formulations). This Applications are also described in a number of patents (e.g. WO 98/55148, EP 0 579 435, EP 0 392 608). In these writings, however, usually only one active ingredient from Cyclodextrin (derivative) encapsulated as several compounds due to different Complex formation constants would be released unevenly by the cyclodextrins. Multiple component inclusion complexes are described in EP 0756 493, on closer inspection, however, this is a salt and not one Two-component mixture of acid and base.

“Cyclodextrin and / or a derivative thereof” in the following means both cyclodextrins with a different number of glucose units in the ring molecule and derivatives of these compounds.

The object of the present invention was to overcome the disadvantages of the prior art avoid or at least mitigate. In particular, treatment and Prophylaxis of intrinsic and / or extrinic skin aging and treatment and prophylaxis of the harmful effects of ultraviolet radiation on the skin permanent, sustainable and without the risk of side effects.

Preparations according to the invention can, especially if crystalline or microcrystalline Solids, for example inorganic micropigments in the inventive Preparations are to be incorporated, including anionic, nonionic and / or contain amphoteric surfactants. Surfactants are amphiphilic substances that are organic, non-polar Can dissolve substances in water.

• - anionische Tenside,
• - kationische Tenside,
• - amphotere Tenside und
• - nichtionische Tenside.

The hydrophilic parts of a surfactant molecule are mostly polar functional groups, for example -COO ^- , -OSO ₃ ^2- , -SO ^3- , while the hydrophobic parts generally represent non-polar hydrocarbon residues. Surfactants are generally classified according to the type and charge of the hydrophilic part of the molecule. There are four groups:

• - anionic surfactants,
• - cationic surfactants,
• - amphoteric surfactants and
• - nonionic surfactants.

Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In an aqueous solution they form negatively charged organic ions in an acidic or neutral environment. Cationic surfactants are characterized almost exclusively by the presence of a quaternary ammonium group. In aqueous solution they form positively charged organic ions in an acidic or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and therefore behave like anionic or cationic surfactants in aqueous solution depending on the pH. They have a positive charge in a strongly acidic environment and a negative charge in an alkaline environment. In the neutral pH range, however, they are zwitterionic, as the following example should illustrate:

RNH ₂ ⁺ CH ₂ CH ₂ COOH X ^- (at pH = 2); X ^- = any anion, e.g. B. Cl ^- ;
RNH ₂ ⁺ CH ₂ CH ₂ COO ^- (at pH = 7);
RNHCH ₂ CH ₂ COO ^- B ⁺ (at pH = 12); B ⁺ = any cation, e.g. B. Na ⁺ .

Polyether chains are typical of non-ionic surfactants. Non-ionic surfactants form in aqueous medium no ions.
