Abstract

Active substance combinations comprises 2-(4-(diethylamino)-2-hydoxybenzoyl)-benzoic acid hexylester and glucosylglycerides. An independent claim is included for a cosmetic preparation comprising the active substance combination.

Description

The The present invention relates to drug combinations of 2- (4- (diethylamino) -2-hydroxybenzoyl) -benzoic acid hexyl ester and one or more glucosylglycerides as well as cosmetic and dermatological sunscreen preparations containing such Drug combinations.

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 mostly derivatives of the 3-benzylidene camphor, 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 well as its Rays damage can cause. It is thus stated that UVA radiation to injury the elastic and collagen fibers of the connective tissue performs what the skin ages prematurely, and that she as the cause of numerous phototoxic and photoallergic reactions you can see. The injurious Influence of UVB radiation can amplified by UVA radiation become.

UV-A radiation may also cause skin damage cause damage to the skin's own keratin or elastin. This will cause elasticity and water storage capacity the skin is reduced, i. The skin becomes less supple and tends for wrinkling. The strikingly high incidence of skin cancer in areas of strong sunlight shows that apparently also damage the genetic information in the cells by sunlight, especially by UV-A radiation caused.

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 free radical compounds, e.g. Hydroxyl radicals. Also undefined radical photoproducts that are formed in the skin itself, can 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) due to increased reactivity. Indeed 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 even ionic species at UV exposure, which in turn oxidative in to be able to intervene in the biochemical processes.

The Pigmentation of human skin, is essentially through the presence of melanin causes. Melanin and its degradation products (Melanoids), carotene, degree of circulation and the nature and Thickness of the stratum corneum and other layers of skin leave skin tones of practically white (at reduced filling or in the absence of blood vessels) or yellowish over light brown-reddish, bluish until brown different nuances and finally appear almost black. The individual skin regions show different amounts of melanin different depth of coloration.

The natural Melanin protects the skin from penetrating UV radiation. The number of melanocytes in the produced melanin granules decide on light or dark skin. With strong pigmentation (for example in colored, but also in fair skinned after melanin is also present in the stratum spinosum and even in the stratum corneum. It attenuates the UV radiation 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 sunburned.
Skin type III tans well on average.
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 the harmful UV radiation is a tangible benefit of natural skin tanning. since a few decades later a "healthy" skin color as a sign especially sports activity and is therefore of a broad consumer stratum is considered desirable. representative the skin types 1 and II, who enjoy such a skin tone want, therefore, rely on self-tanning preparations anyway. But also Representatives of skin type III who are not too aware of the risks sunbathing while still looking tanned, are grateful Target groups for self-tanning preparations.

One Another disadvantage of sunscreen preparations with conventional Skin-moisturizing ingredients is that a very high moisture content in the skin detrimental to the sun protection performance of UV filters can affect. Desirable is to provide sunscreen preparations that are characterized by a balanced skin moisturizing.

The To remedy disadvantages of the prior art was therefore the task of the present invention.
