Abstract

Use of cosmetic preparations containing (i) glycyrrhizin and / or glycyrrhetinic acid and (ii) 2,4-bis - {[4- (2-ethylhexyloxy) -2-hydroxy] -phenyl} -6- (4-methoxyphenyl) - 1,3,5-triazine for the care of light-stressed skin.

Description

The present invention relates to cosmetic and dermatological preparations for tanning the skin, especially those which simultaneously provide protection against UV radiation.

The damaging effect of the ultraviolet part of solar radiation on the skin is well known. While rays with a wavelength less than 290 nm (the so-called UVC range) 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 range, cause erythema simple sunburn or even more or less severe burns.

As a maximum of the erythema efficiency of sunlight, the narrower range around 308 nm is given.

For protection against UVB radiation, numerous compounds are known, which are mostly derivatives of 3-Benzylidencamphers, 4-Aminobenzoësäure, cinnamic acid, salicylic acid, benzophenone and also of 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, since even its rays can cause damage. Thus, UVA radiation has been shown to cause damage to the connective tissue elastic and collagenous fibers, prematurely aging the skin, and to be the cause of many phototoxic and photoallergic reactions. The damaging influence of UVB radiation can be amplified by UVA radiation.

UVA radiation can also cause skin damage by damaging the skin's own keratin or elastin. As a result, elasticity and water storage capacity of the skin are reduced, d. H. The skin becomes less supple and tends to wrinkle. The strikingly high prevalence of skin cancer in areas of strong sunlight shows that apparently damage to the genetic information in the cells by sunlight, especially caused by UV-A radiation.

However, the UV radiation can also lead to photochemical reactions, in which case the photochemical reaction products intervene in the skin metabolism.

Predominantly, such photochemical reaction products are free-radical compounds, eg. B. hydroxyl radicals. Undefined free radical photoproducts that form in the skin itself may show uncontrolled sequelae due to their high reactivity. But also singlet oxygen, a non-radical excited state of the oxygen molecule can occur on UV irradiation, as well as short-lived epoxides and many others. Singlet oxygen, for example, is distinguished from the normally present triplet oxygen (radical ground state) by increased reactivity. However, there are also excited, reactive (radical) triplet states of the oxygen molecule.

Furthermore, UV radiation counts as ionizing radiation. There is thus the risk that ionic species may also be formed on exposure to UV radiation, which in turn may intervene oxidatively in the biochemical processes.

The pigmentation of human skin is essentially caused by the presence of melanin. Melanin and its degradation products (melanoids), carotene, degree of blood flow and the nature and thickness of the stratum corneum and other skin layers leave skin shades of virtually white (with reduced filling or in the absence of blood vessels) or yellowish to light brown-reddish, bluish to brown different nuances and finally appear almost black. The individual skin regions show different depth of color due to different amounts of melanin.

The natural melanin protects the skin from penetrating UV radiation. The number of melanin granules produced in the melanocytes determines whether they are light or dark-skinned. In case of severe pigmentation (eg in colored persons, but also in fair-skinned persons after some UV irradiation), melanin is also found in the stratum spinosum and even in the stratum corneum. It attenuates UV radiation by up to about 90% before it reaches the corium.

Depending on photosensitivity, the following skin types are usually distinguished: Skin type I never tans, always gets a sunburn. Skin type II hardly tans, easily gets a sunburn. Skin type III tans average good. Skin type IV tans easily and persistently, almost never gets sunburned. Skin type V dark, often almost black skin never gets sunburned.

The natural shielding of harmful UV radiation is a tangible benefit of natural skin tanning. In addition, for some decades a "healthy" skin color has been a sign of especially sporting activity and is therefore considered by a broad consumer to be desirable. Representatives of skin types I and II, who want to enjoy such a skin tone, are therefore dependent on self-tanning preparations anyway. But also representatives of skin type III, who do not want to take too much exposure to the risks of sunbathing and still want to look tanned, are grateful target groups for self-tanning preparations.

Artificial skin tanning can be effected by cosmetic or medical means, whereby essentially the following approaches play a role:
Carotene is stored in the subcutaneous adipose tissue by regular intake of carotene preparations, the skin gradually turns orange to yellow-brown.

With the help of washable make-up preparations a slight skin tone can be achieved (eg extracts of fresh green walnut shells, henna)

The staining can also be done by way of chemical modification of the horny layer of the skin with so-called self-tanning preparations. The most important active ingredient is dihydroxyacetone (DHA). The skin tanning achieved in this way is not washable and is only removed with the normal desquamation of the skin (after approx. 10-15 days). Dihydroxyacetone can be referred to as ketotriose and reacts as 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 sometimes melanoidins to be named.

A disadvantage of tanning with dihydroxyacetone is that the skin tanned with it is not protected against sunburn in contrast to "tanned" skin:
Glycyrrhetinic acid is characterized by the following structure:

In addition to the naturally occurring 18 β-form, there is also an 18 α-form. The glycyrrhetinic acid isolable from licorice (Glycyrrhiza glabra, Leguminosae) is the aglycone of glycyrrhizin (which is the 2β-glucuronido-α-glucuronide of glycyrrhetinic acid).

Glycyrrhizin is characterized by the following structure:

Glycyrrhetinic acid is used as an anti-inflammatory agent. Glycyrrhetinic acid 3-hemisuccinate serves as an antiulcer drug.

Glycyrrhizin has an anti-inflammatory effect and is used in the form of licorice juice (syrupus liquiritiae) as a cough suppressant and expectorant.

Glycyrrhetinic acid and glycyrrhizin are known to the person skilled in the art as active ingredients having a skin-lightening activity.

The disadvantage, however, is that glycyrrhizin, glycyrrhetinic acids and / or the corresponding sodium, ammonium and potassium salts and / or the corresponding esters have a photostability in cosmetic bases.

The object of the present invention was therefore to find ways that avoid the disadvantages of the prior art.

• (i) Glycyrrhizin und/oder Glycyrrhetinsäure und

the disadvantages of the prior art would remedy.

It is particularly advantageous if the preparations contain 0.0001 to 5% by weight, in particular 0.001 to 1% by weight, very particularly 0.005 to 0.50% by weight, of glycyrrhizin and / or glycyrrhetinic acid, based on the total weight of the preparation ,

It is furthermore advantageous if the preparations contain from 0.001 to 5% by weight, in particular from 0.01 to 3% by weight, very particularly from 0.5 to 2% by weight, of 2,4-bis- [4- (2 Ethylhexyloxy) -2-hydroxy] -phenyl} -6- (4-methoxyphenyl) -1,3,5-triazine, based on the total weight of the composition.
