Abstract

Cosmetic or dermatological formulations contain physiologically-compatible thiosulfonic acid(s) (I). An Independent claim is also included for the use of (I) as antioxidant and/or free radical scavenger in cosmetic or dermatological formulations.

Description

The present invention relates to cosmetic and dermatological preparations with an effective content of physiologically acceptable thiosulfonic acids. Insbesonde The present invention relates to cosmetic preparations with an effective Protection against harmful oxidation processes in the skin, but also for the protection kos metic preparations themselves or for the protection of the ingredients of cosmetic Zube preparations for harmful oxidation processes.

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

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

The present invention further relates to drug combinations and preparations which for the prophylaxis and treatment of the photosensitive skin, in particular of Photo dermatoses, serve.  

The damaging effect of the ultraviolet part of solar radiation on the skin is well known. While rays with a wavelength smaller than 290 nm (the so-called UVC range), absorbed by the ozone layer in the earth's atmosphere be, cause rays in the range between 290 nm and 320 nm, the soge called UVB, erythema, simple sunburn or even more or less severe burns.

As a maximum of the erythema efficiency of sunlight becomes the narrower area indicated at 308 nm.

For protection against UVB radiation, numerous compounds are known in which it derivatives of 3-benzylidene camphor, 4-aminobenzoic acid, cinnamic acid, salicylic acid, benzophenone and 2-phenylbenzimidazole.

Also for the range between about 320 nm and about 400 nm, the so-called UVA Area, it is important to have filter substances available as its rays Can cause reactions in photosensitive skin. It has been proven that UVA Radiation damage the elastic and collagen fibers of the connective tissue What leads the skin to prematurely age, and that it is the cause of numerous photo toxic and photoallergic reactions can be seen. The damaging influence of UVB radiation can be amplified by UVA radiation.

For protection against the rays of the UVA range, therefore, certain derivatives of the Dibenzoylmethane, whose photostability (Int J. Cosm. Science 10, 53 (1988)), is not given sufficiently.

The UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products interfere with the skin metabolism.

Predominantly, such photochemical reaction products are ra dicalic compounds, for example hydroxy radicals. Also undefined radical Photoproducts, which develop in the skin itself, can due to their high Reactivity uncontrolled subsequent reactions to the day. But also Singulettsauer substance, a non-radical excited state of the oxygen molecule can be Irradiation occur, as are short-lived epoxides and many others. singlet  For example, is distinguished from the normally existing Triplettsau erstoff (radical ground state) by increased reactivity. However, there exists also excited, reactive (radical) triplet states of the oxygen molecule.

Furthermore, UV radiation counts as ionizing radiation. So there is a risk that also arise ionic species on UV exposure, which in turn oxidative in to be able to intervene in the biochemical processes.

To prevent these reactions, the cosmetic or dermatological Formulations additional antioxidants and / or radical scavengers are incorporated.

It has already been suggested vitamin E, a substance with known antioxida tive effect in sunscreen formulations, but still remains here scored far behind the hoped for effect.

The object of the invention was therefore also cosmetic, dermatological and pharma to provide active substances and preparations as well as sunscreen formulations, those for the prophylaxis and treatment of photosensitive skin, in particular Photo dermatoseh, preferably PLD serve.

Other terms for polymorphic photodermatosis include PLD, PLE, Mallorcan Acne and a variety of other names, as described in the literature (eg. Voelckel et al. Zentralblatt skin and venereal diseases (1989), 156, p. 2) given are.

Erythematous skin manifestations also occur as a side effect in certain Skin disorders or irregularities. For example, the typical skin rash in the appearance of acne regularly more or less reddened.

Mainly antioxidants are used as protective substances against the spoilage of them used preparations containing. Nevertheless, it is known that in menschli Skin and animal skin undesirable oxidation processes can occur. Such Processes play an essential role in skin aging.  

In the article "Skin Diseases Associated with Oxidative Injury" in "Oxidative Stress in the Matology, p. 323 et seq. (Marcel Decker Inc., New York, Basel, Hong Kong, Ed Jürgen Fuchs, Frankfurt, and Lester Packer, Berkeley, California), become oxidative Damage to the skin and its nearer causes listed.

If human hair is to be dyed permanently, only oxi are used in practice qualifying hair dyeing process into consideration. During oxidative hair dyeing the Ausbil takes place formation of the dye chromophore by reaction of precursors (phenols, amino phenols, more rarely diamines) and bases (mostly p-phenylenediamine) with the Cxi dationsmittel, mostly hydrogen peroxide. Hydrogen peroxide concentrations by 6% are usually used.

Usually, it is assumed that in addition to the dyeing also a bleach effect by the hydrogen peroxide. In oxidatively dyed human hair are similar to bleached hair, microscopic holes in the places at de melanin granules were detectable.

The fact is that the oxidizing agent hydrogen peroxide not only with the Farbvorstu but also react with the hair substance and possibly a Damage to the hair can cause.

Antioxidants are substances that prevent oxidation processes or which the Prevent auto-oxidation of unsaturated compounds containing fats. antioxidants which are also used in the field of cosmetics and pharmacy, For example, α-tocopherol, especially in the form of α-tocopheryl acetate, Se samol, gallic acid derivatives, butylhydroxyanisole and butylhydroxytoluene.

Also, for the sake of preventing such reactions, cosmetic formu In addition, antioxidants and / or radical scavengers can be incorporated.

Although some antioxidants and radical scavengers are known. So is already in the US Pa pending 4,144,325 and 4,248,861 and from numerous other documents been beaten, vitamin E, a substance with known antioxidant activity in Nevertheless, the effect achieved here also remains here far behind the hoped for.  

An object of the present invention was to overcome the disadvantages of the prior art to eliminate. In particular, active substances or preparations should be such active substances containing, when used, the damage to the Skin and / or hair at least reduced by oxidative influence, if not can be completely prevented.

Another object of the present invention was to provide cosmetic preparations The hairstyles available before or after treatment of the hair with hair coloring preparations, even those containing strong oxidizing agents such as z. As hydrogen peroxide, counteract their damaging oxidation effect.

In particular, active ingredients and preparations containing such active ingredients, should cosmetic and dermatological treatment and / or prophylaxis of erythematous, inflammatory, allergic or autoimmune reactive phenomena, in particular Der matose, but also the appearance of the "Stinging" provided the.

Finally, an object of the present invention was to provide antioxidants to be stable over a wide pH range, especially in the pH range <5 are.

It was, however, surprising and not foresee the expert that kosmeti or dermatological preparations containing physiologically tolerated chen thiosulfonic acids or the use of physiologically acceptable thiosul Fonsäuren as antioxidant and / or as radical scavenger in cosmetic or dermatolo the solution to these problems and the disadvantages of Prior art remedy.

In particular, it was not foreseen that cosmetic or dermatological preparations having a pH of <5 containing physiologically compatible thiosulfonic acids or the use of physiologically acceptable Thiosulfonic acids as antioxidant and / or as radical scavenger in cosmetic or the matological preparations, which have a pH of <5, exceed extremely advantageous properties in the sense of the solution of all the above tasks to draw.
