Abstract

Cosmetic or dermatological preparation (I) comprises benfotiamine (A). ACTIVITY : Dermatological; Antipsoriatic; Antiinflammatory; Antiallergic; Immunosuppressive; Vasotropic. MECHANISM OF ACTION : None given.

Description

The The present invention relates to cosmetic or dermatological Preparations containing active ingredients for care and protection the skin, especially the sensitive skin as well as especially in the Foreground standing by intrinsic and / or extrinsic Factors of aging or aging skin and the use of such Active substances and combinations of such active ingredients in the field cosmetic and dermatological skin care.

Under Cosmetic skincare is first and foremost to understand that natural Function of the skin as a barrier against environmental influences (for example dirt, chemicals, Microorganisms) and against the loss of endogenous substances (e.g. natural Fats, electrolytes) or restored.

Becomes this function disturbed, it can be overpowered Absorption of toxic or allergenic substances or infestation of Microorganisms and as a result to toxic or allergic skin reactions come.

at old skin, for example, the regenerative renewal slows down, in particular, the water-binding capacity of the horny layer decreases. she becomes therefore inflexible, dry and cracked ("physiologically" dry skin). A barrier damage is the consequence. The skin becomes vulnerable for negative environmental influences like the invasion of microorganisms, toxins and allergens. When It can even lead to toxic or allergic skin reactions come.

at Pathologically dry and sensitive skin is a barrier damage a priori. Epidermal intercellular lipids become defective or in insufficient Quantity or composition formed. The consequence is an increased permeability the horny layer and insufficient protection of the skin from loss hygroscopic substances and water.

The Barrier effect of the skin can over the determination of transepidermal water loss (TEWL - transepidermal water loss). This is the evaporation of water from inside the body without the inclusion of water loss during sweating. The determination the TEWL value has turned out to be extraordinary has proved informative and may be more chapped or crippled for diagnosis Skin, to determine the tolerability chemically diversified surfactants and the like be used.

For the beauty and Nourishment of the skin is the water content in the uppermost skin layer of highest importance. It can be favorably influenced to a limited extent by introducing moisture regulators.

anionic Surfactants, which are generally components of cleaning preparations are, can increase pH in the horny layer for a long time, which means regenerative processes, the restoration and renewal of the barrier function of the Serve skin, severely disabled. In this case, turns in the horny layer between regeneration and the loss of essential substances regular extraction newer, more often very unfavorable State of equilibrium, which is the external appearance of the skin and the physiological functioning of the horny layer crucial impaired.

Nice in a simple water bath without the addition of surfactants it comes first to a swelling of the horny layer of the skin, the degree of this Swelling for example of the duration of the bath and its temperature depends. At the same time become water-soluble Fabrics, e.g. water-soluble Dirt components, but also skin-own substances, which are responsible for the water-binding capacity of the Horn layer are responsible, washed off or washed out. By the skin's own surfactants Substances are also dissolved and washed out skin fats to a certain extent. This requires after initial Swelling a subsequent significant dehydration of the skin, the through detergent additives even stronger can be.

at healthy skin are these processes generally irrelevant, since the protective mechanisms of the skin such slight disturbances the upper layers of the skin can readily compensate. But even in the case of non-pathological deviations from normal status, e.g. due to environmental damage or irritation, photodamage, aging skin etc., the protective mechanism of the skin surface is disturbed. It may be He then no longer able to do his job on his own fulfill and must be through external action be regenerated.

In addition, it is known that lipid composition and amount of the horny layer of the patholo In the healthy, normally hydrated skin of an age group of the same age group, the dry and non-diseased skin of younger and older people is different from normal. The changes in the lipid pattern of the very dry, non-eczematous skin of patients with atopic eczema represent an extreme case for the deviations that are found in the dry skin of healthy people.

These Deviations particularly concern the ceramides which in their amount greatly reduced and additionally composed differently are. A striking feature is the deficit of the Ceramides 1 and 3, wherein in particular for the ceramide 1 is known, that in a special way the order of lipids in the intercellular membrane systems increases.

Adverse changes may be based in the lipid membranes of the type described above on misdirected lipid biosynthesis and also increase in the end the transepidermal water loss. A long-standing barrier barrier again makes the skin, which is healthy in itself, more sensitive and can in a single case to the emergence of eczematous operations contribute in the diseased skin.

The Effect of ointments and creams on barrier function and hydration The horny layer is usually not in a recovery or strengthening physicochemical properties of lamellae from intercellular lipids. A significant partial effect is based on the mere coverage of the treated skin areas and the resulting water retention in the underlying Stratum corneum. Co-applied hygroscopic substances bind this Water, causing a measurable increase in water content comes in the horny layer. This purely physical barrier can however, be relatively easily removed. After weaning of the product, the skin then returns very quickly to the condition back before treatment. About that In addition, the skin care effect may diminish with regular treatment, so that finally even while the treatment of the status quo is achieved again. For certain Products, the condition of the skin worsens after weaning in certain circumstances temporarily. A sustainable product effect is usually not or only in a limited way Dimensions achieved.

Around the deficit Skin at its natural Support regeneration and to strengthen their physiological function, are topical preparations more recently, intercellular lipid mixtures have increasingly been added, used by the skin to rebuild the natural barrier should be. However, these lipids are, in particular but the ceramides to very expensive raw materials. In addition, their effect usually much lower than hoped.

aim Thus, it has been the object of the present invention to find ways to overcome the disadvantages of the prior art. In particular, the effect should be the skin care products are physiological, fast and sustainable.

Under Skin care in the sense of the present invention is primarily to understand that the natural Function of the skin as a barrier against environmental influences (eg dirt, chemicals, Microorganisms) and against the loss of endogenous substances (eg Water, lipids, electrolytes) strengthened or restored becomes.

Products for the care, treatment and cleaning of dry and stressed Skin is known. However, their contribution to regeneration a physiologically intact, hydrated and smooth horny layer extensive and limited.

The Effect of ointments and creams on barrier function and hydration the horny layer is based essentially on the cover (occlusion) of the treated dermal districts. The ointment or cream poses, so to speak a (second) artificial one Barrier that is supposed to prevent the loss of water from the skin. Correspondingly easy can this physical barrier - for example, with detergents - again be removed, causing the original, impaired State is reached again. In addition, the skin care effect with regular treatment ease up. After discontinuation of the product application, the skin returns very well quickly back to the state before treatment. at Certain products deteriorate the condition of the skin circumstances even temporarily. A sustainable product effect is usually not or only in a limited way Dimensions achieved.

The effect of some pharmaceutical preparations on the barrier function of the skin even exists in a selective barrier damage which is supposed to enable active substances to penetrate into or through the skin into the body. A disturbed appearance of the skin is partly as a side effect billi accepted.

The Effect of nourishing cleaning products consists essentially in an efficient refatting with sebum lipid-like Substances. By the simultaneous reduction of the surfactant content such preparations the damage to the horny layer barrier continues to be limited.

the The prior art, however, lacks preparations which the barrier function and the hydration of the horny layer are positive affect and the physicochemical properties of the horny layer and in particular strengthen the lamellae of intercellular lipids or even restore.

task It was therefore the object of the present invention to overcome the disadvantages of the prior art to eliminate the technology. In particular, skin-care preparations should and preparations provided for cleansing the skin which preserve the barrier properties of the skin or Restore, especially when the natural regeneration of the skin not enough. They should also be used for treatment and prophylaxis consequential damages skin dehydration, such as fissures or inflammatory or allergic processes or atopic dermatitis be. Object of the present invention was also stable skin care cosmetic and / or dermatological agents available which protect the skin from environmental influences such as sun and wind. Especially The effect of the preparations should be physiological, fast and be sustainable.

Furthermore The invention relates to preparations with extremely low so-called "stinging potential".

The Problem "sensitive Skin "concerns one growing number of adults and children. With Sensitive Skin you get a combination of different symptoms, like hyperreactive and intolerant skin. But also atopic skin can be subsumed under it become. These skin conditions are often referred to by those affected, not quite correct, as "allergic" skin. Although an allergic disease to symptoms of sensitive skin to lead can, the appearance is "sensitive Skin "not up Allergic limited.

at People with sensitive, sensitive or vulnerable skin can one labeled "stinging" (hurting, burning, hurting) neurosensory phenomenon to be watched. This "sensitive Skin "is different basically from "dry skin" with thickened and indurated Horn layers.

typical Stinging reactions in sensitive skin are redness, Tensing and burning of the skin as well as itching.

When neurosensory phenomenon is the itching in atopic skin, as well as itching in skin diseases.

"Stinging" phenomena can be considered as cosmetically treated disorders be considered. Severe itching, especially in atopy severe skin itching can also be more severe dermatological disorder be designated.

typical, associated with the terms "stinging" or "sensitive skin", disturbing neurosensory phenomena are skin redness, Tingling, tingling, tightening and burning of the skin and itching. she can by stimulating environmental conditions e.g. Massage, surfactant action, Weather influence such as sun, cold, Dryness, but also damp heat, thermal radiation and UV radiation, e.g. the sun, to be evoked.

In "Journal of the Society of Cosmetic Chemists "28, P.197 - 209 (May 1977) describe P.J.Frosch and A. M. Kligman a method for appraisal of the "stinging potential" administered Substances. As positive substances, here e.g. Lactic acid and Pyruvic acid used. When measuring by this method but were also amino acids, in particular Glycine, detected as neurosensory active (such substances are called "stinger").

To So far, such sensitivity has been completely different individually different substances. This means, A person who experiences "stinging effects" when in contact with a substance will most likely experience repeatedly at each additional contact. The contact with other "stingers" can just as well without any reaction.

Lots more or less sensitive people have even when using some deodorizing or antiperspirant preparations under erythematous Skin symptoms to suffer.

Erythematous skin symptoms also occur as side effects in certain skin diseases or irregularities on. For example, the typical skin rash is the appearance the acne regularly more or less reddened.

It So was the object of the present invention, the disadvantages of the prior art.

Especially should contain active substances and preparations containing such active substances, for cosmetic and dermatological treatment and / or prophylaxis erythematous, inflammatory, allergic or autoimmune-reactive phenomena, in particular Dermatoses, but also the appearance of the "Stinging" provided become.

Further should such agents, or preparations, such agents containing, available be placed, which for immune stimulation of the skin, while beneficial also for immune stimulation in the sense of promoting wound healing Effect, can be used.

In a further preferred embodiment The present invention relates to cosmetic and dermatological Preparations for the prophylaxis and treatment of cosmetic or dermatological skin lesions such as. the unwanted Pigmentation, for example local hyper- and false pigmentation (for example, liver spots, freckles), but also to the pure cosmetic whitening greater, the individual skin type in itself quite appropriately pigmented Skin surfaces.

For pigmentation the skin is responsible for the melanocytes, which are in the lowest Layer of the epidermis, the stratum basale, beside the basal cells as - ever by skin type either isolated or more or less frequently occurring pigment-forming cells are found. Melanocytes contain as characteristic cell organelles melanosomes that are stimulated by Reinforced UV radiation Form melanin. This is transported into the keratinocytes and gets a more or less pronounced brownish or brown skin color out.

melanin is formed as the final stage of an oxidative process, in which Tyrosine with the help of the enzyme tyrosinase via 3,4-dihydroxyphenylalanine (Dopa), dopa-quinone, leucodopachrom, dopachrome, 5,6-dihydroxyindole and indole-5,6-quinone finally is converted into melanin.

issues with hyperpigmentation of the skin have many causes or are concomitant many biological processes, e.g. UV radiation (e.g., freckles, ephelides), genetic disposition, False pigmentation of the skin during wound healing or scarring or skin aging (e.g., Lentigines seniles).

It active ingredients and preparations are known which skin pigmentation counteract. In practical use are essentially preparations on the basis of hydroquinone, which, however, partly after several weeks Application to show their effect, their overly long application On the other hand, for toxicological reasons is questionable. Also the Inhibition of tyrosinase with substances such as kojic acid, ascorbic acid and azelaic acid and their derivatives are familiar, but has cosmetic and dermatological disadvantages.

Also to remedy these evils, was task of the available invention.

The aim of skin care is also to compensate for the daily loss of fat and water loss of the skin. This is especially important when the natural regeneration capacity is insufficient. In addition, skincare products should protect against environmental influences, especially from the sun and wind zen and delay skin aging.

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

The chronological skin aging is caused eg by endogenous, genetically determined factors. In the epidermis and dermis, aging causes, for example, the following structural damage and dysfunctions, which may also fall under the term "senile xerosis":

• a) dryness, roughness and formation of dryness wrinkles,
• b) itching and
• c) diminished fatty tissue suppression through sebaceous glands (eg after washing).

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

Exogenous factors, such as UV light and chemical noxae, can be cumulatively effective and, for example, accelerate or supplement endogenous aging processes. In the epidermis and dermis, the following structural and functional disorders in the skin occur, in particular due to exogenous factors, which go beyond the extent and quality of the damage caused by chronological aging:

• d) Visible vascular dilations (telangiectasias, cuperosis);
• e) slackness and formation of wrinkles;
• f) local hyper-, hypo- and false pigmentation (eg age spots) and
• g) increased susceptibility to mechanical stress (eg cracking).

The The present invention particularly relates to care products the natural one Way of aging skin, as well as to treat the sequelae of Photoaging, in particular the phenomena listed under a) to g).

Products For the care of aged skin are known. They contain e.g. Retinoids (vitamin A acid and / or their derivatives) or vitamin A and / or its derivatives. Their effect on the structural damage is but limited in scope. About that There are also significant difficulties in product development, the active ingredients sufficiently against oxidative decay to stabilize. The use of vitamin A acid-containing products conditioned about that In addition, often strong erythematous Skin irritation. Retinoids are therefore only in low concentrations used.

Especially 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 ingredients of cosmetic Preparations against harmful Oxidation processes.

The The present invention further relates to antioxidants, preferably those which are used in skin care cosmetic or dermatological Preparations are used. In particular, the invention also relates cosmetic and dermatological preparations, such antioxidants containing. In a preferred embodiment, the present invention relates Invention cosmetic and dermatological preparations for prophylaxis and treatment of cosmetic or dermatological lesions such as. Skin aging, especially that caused by oxidative processes caused skin aging.

Farther the present invention relates to active substances and preparations, containing such active ingredients, for cosmetic and dermatological Treatment or prophylaxis erythematous, inflammatory, allergic or autoimmune reactive phenomena, especially dermatoses.

The The present invention relates in a further advantageous embodiment Active substance combinations and preparations for prophylaxis and Treatment of photosensitive skin, especially photodermatoses, serve.

The damaging Effect of the ultraviolet part of solar radiation on the skin is well known. While Beams with one wavelength, which is less than 290 nm (the so-called UVC range), from the Ozone layer in the earth's atmosphere be absorbed, causing rays in the range between 290 nm and 320 nm, the so-called UVB range, an erythema, a simple Sunburn or even more or less severe burns.

When a maximum of the erythema efficiency of sunlight becomes the tighter Range indicated around 308 nm.

To the Protection against UVB radiation, numerous compounds are known which are derivatives of 3-Benzylidencamphers, 4-aminobenzoic acid, the cinnamic acid, salicylic acid, benzophenone and 2-phenylbenzimidazole.

Also for the Range between about 320 nm and about 400 nm, the so-called UVA range, it is important to have available filter substances, as its rays Can cause reactions in photosensitive skin. It It is proven that UVA radiation to injury the elastic and collagen fibers of the connective tissue performs what the skin ages prematurely, and that they are the cause of numerous phototoxic and photoallergic Reactions can be seen. The injurious Influence of UVB radiation can be amplified by UVA radiation.

To the Protection against the rays of the UVA range therefore becomes certain Derivatives of dibenzoylmethane used whose photostability (Int. J. Cosm. Science 10, 53 (1988)), is not given sufficiently is.

The UV radiation can also lead to photochemical reactions, wherein then the photochemical reaction products in the skin metabolism intervention.

mainly are such photochemical reaction products to radical compounds, for example hydroxyl radicals, singlet oxygen. Also undefined radical photoproducts, which are in the skin can arise yourself because of their high reactivity uncontrolled follow-up reactions to the day. But also singlet oxygen, a non-radical excited state of the oxygen molecule can with UV irradiation occur, as are short-lived epoxides and many others. singlet for example, is distinguished from the normally present Triplet oxygen (radical ground state) by increased Reactivity out. However, there are also excited, reactive (radical) triplet states of the oxygen molecule.

Further counts UV radiation to ionizing radiation. So there is a risk that too ionic species are formed on exposure to UV, which then in turn oxidative in the biochemical processes are able to intervene.

Around to prevent these reactions the cosmetic or dermatological formulations additional Antioxidants and / or radical scavengers be incorporated.

It has already been suggested vitamin E, a substance with known to use antioxidant activity in sunscreen formulations, Nevertheless, the achieved effect remains far behind the hoped for back.

task The invention was therefore also cosmetic, dermatological and pharmaceutical active ingredients and preparations as well as sunscreen formulations to provide for the prophylaxis and treatment of photosensitive Skin, especially photodermatoses, preferably PLD serve.

Further Designations for the polymorphic light dermatosis are PLD, PLE, Mallorca acne and a variety of other designations as described in the literature (e.g., A. Voelckel et al, Zentralblatt Skin and venereal diseases (1989), 156, P.2).

Mainly Antioxidants as protective substances against the spoilage of preparations containing them used. Nevertheless, it is known that in human and also animal skin unwanted Oxidation processes can occur. Such processes play an essential role in skin aging.

in the Essay "Skin Diseases Associated with Oxidative Injury "in" Oxidative Stress in Dermatology ", P. 323 ff. (Marcel Decker Inc., New York, Basel, Hong Kong, publisher: Jürgen Fuchs, Frankfurt, and Lester Packer, Berkeley, California) oxidative damage the skin and its closer Causes listed.

Also For the reason, to prevent such reactions can be cosmetic or dermatological formulations additionally antioxidants and / or radical scavengers be incorporated.

Though Some antioxidants and radical scavengers are known. That's already in US Patent 4,144,325 and 4,248,861 and from numerous other documents have been proposed, vitamin E, a substance with known antioxidant activity in sunscreen formulations nevertheless, the effect achieved here remains wide behind the hoped-for back.

task The present invention thus seeks to find ways that the Avoid disadvantages of the prior art. In particular, should Effect of remedying the endogenous, chronological and exogenous Skin aging related damage and the prophylaxis lasting, sustainable and without the risk of Be side effects.

According to the invention the evils of the Prior art eliminated by cosmetic or dermatological Preparations containing Benfotiamine.

Accordingly, according to the invention also the use of benfotiamine for the production of cosmetic or dermatological preparations for strengthening the barrier function of the skin.

Benfotiamine (S-benzoylthiamine O-monophosphate) is a vitamin B1 analog and has been known since the early 1960s. It is characterized by the following structure:

vitamin B1 as such is the longest known vitamin, whose deficiency symptoms (Beri-Beri's disease) already common for millennia are. The symptoms are loss of appetite, vomiting, absorption disorders, Fatigue, Polyneuritides in the form of muscle weakness, numbness, paralysis and mental changes like memory loss, Confusion, depression, arrhythmia and disorders of the water balance. The polyneuropathy seen in alcoholics is said to be due to a significant extent to vitamin B1 deficiency due to decreased absorption as well as lack of food intake. It is to be assumed that by Vitamin B1 deficiency peripheral circulatory disorders and degeneration be triggered on the medullary sheaths of the nerves and on the white matter of the brain.

Though describes the JP 2001/081027 describes cosmetics with a content to Benfotiamin, however, this writing could not lead the way to the present Invention exhibit.

The hydrophilic portions of a surfactant molecule are usually polar functional groups, for example -COO ^- , -OSO ₃ ^2- , -SO ₃ ^- , while the hydrophobic parts are usually nonpolar hydrocarbon radicals. Surfactants are generally classified according to the nature and charge of the hydrophilic part of the molecule. Here four groups can be distinguished:

• Anionic surfactants,
• Cationic surfactants,
• • amphoteric surfactants and
• • nonionic surfactants.

Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution, they form negatively charged organic ions in an acidic or neutral medium. Cationic surfactants are almost exclusively characterized 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 behave accordingly in aqueous solution depending on the pH as anionic or cationic surfactants. 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 is intended to illustrate:

Typical for non-ionic Surfactants are polyether chains. Nonionic surfactants form in aqueous medium no ions.
