Cosmetic and dermatological light protection formulations containing unsymmetrically substituted triazine derivatives and surface-active sucrose esters

The present invention relates to cosmetic and dermatological light protection preparations, in particular it relates to sand-repellent cosmetic and dermatological light protection preparations.

The damaging effect of the ultraviolet part of solar radiation on the skin is generally known. Depending on their respective wavelengths, the rays have different effects on the skin organ: The so-called UV-C radiation with a wavelength that is less than 290 nm is absorbed by the ozone layer in the earth's atmosphere and therefore has no physiological significance. In contrast, rays in the range between 290 nm and 320 nm, the so-called UV-B range, cause erythema, simple sunburn or even more or less severe burns. The narrower range around 308 nm is given as a maximum of the erythema effectiveness of sunlight.

Numerous compounds are known for protection against UV-B radiation, which are, for example, derivatives of 3-benzylidene camphor, 4-aminobenzoic acid, cinnamic acid, salicylic acid, benzophenone, 2-phenylbenzimidazole and s-triazine.

It has long been erroneously assumed that long-wave UV-A radiation with a wavelength between 320 nm and 400 nm has only a negligible biological effect. In the meantime, however, numerous studies have shown that UV-A radiation is far more dangerous than UV-B radiation in terms of triggering photodynamic, especially phototoxic reactions and chronic changes in the skin. Radiation is. The damaging influence of UV-B radiation can also be increased by UV-A radiation.

So it is u. a. have proven that even UV-A radiation under normal everyday conditions is sufficient to damage collagen and elastin fibers, which are essential for the structure and firmness of the skin, within a short period of time. This leads to chronic light-induced skin changes - the skin "ages" prematurely. The clinical appearance of skin aged by light includes, for example, wrinkles and fine lines and an irregular, furrowed relief. Furthermore, the areas affected by light-induced skin aging can have irregular pigmentation Brown spots, keratoses and even carcinomas or malignant melanomas are possible, and skin that has aged prematurely due to everyday UV exposure is also characterized by less activity of the Langerhans cells and a mild, chronic inflammation.

About 90% of the ultraviolet radiation reaching the earth consists of UV-A rays. While UV-B radiation varies greatly depending on numerous factors (e.g. time of year and time of day or latitude), UV-A radiation remains relatively constant day by day, irrespective of the time of year, day or geographical factors. At the same time, the majority of UV-A radiation penetrates the living epidermis, while around 70% of UV-B rays are retained by the horny layer.

It is therefore of fundamental importance that cosmetic and dermatological light protection preparations offer adequate protection against both UV-B and UV-A radiation.

In general, the light absorption behavior of light protection filter substances is very well known and documented, especially since most industrialized countries have positive lists for the use of such substances, which create very strict standards on the documentation ^¬ mentation.

However, the use concentration of known light protection filter substances known as solids is frequently - especially in combination with other substances to be dissolved - borders. It therefore presents certain formulation difficulties to achieve higher sun protection factors or UV-A protection performance.

The sunburn or the light erythema are the acute manifestations of the influence of light. In addition to the effects of UV rays already described, the subsequent reaction of the skin also leads to reduced sebum production and drying of the skin. To alleviate and care for these phenomena, the prior art knows products that are used after sunbathing and usually contain special active ingredients, such as, for example, ^■ moisturizing and moisturizing agents,

^■ anti-inflammatory and cooling substances,

^■ locally anesthetic substances and / or

^■ disinfectants to prevent possible skin infections.

These so-called aftersun or apres-soleil preparations are intended to cool the skin after sunbathing and to improve its moisturizing ability, whereby the imparting of the cooling effect plays a central role. However, the state of the art lacks products that protect the skin from drying out during UV radiation and provide sufficient care.

Another disadvantage of the prior art is that conventional light protection formulations leave a mostly sticky film on the skin. This has e.g. B. when such products are used on a sandy beach, the result is that the sand sticks to the body, which is perceived by the user as unpleasant and, in the worst case, can lead to the sunscreen being used too little or not at all. Since there is usually a more or less strong wind at the sea, this disadvantage usually occurs even when the body does not come into direct contact with the sand - for example when sunbathing on a deck chair - because the sand dust whirling around in the wind also occurs adheres to the creamed areas of the skin.

A further object of the present invention was therefore to find light protection formulations which, after use, do not leave any sand stuck to the creamy skin, which are therefore to be described as sand-repellent.

It was surprising and unforeseeable for the person skilled in the art that cosmetic or dermatological emulsions effective in protecting against light, characterized in that they

(a) one or more sucrose esters and

(b) contain at least one UV filter substance, selected from the group of asymmetrically substituted azine derivatives, to remedy the disadvantages of the prior art.

The emulsions according to the invention are preferably O / W emulsions.

In all respects, the emulsions according to the invention are extremely satisfactory preparations, which are not limited to a restricted selection of raw materials. Accordingly, they are particularly suitable to serve as the basis for forms of preparation with a variety of uses. The preparations according to the invention show very good sensory and cosmetic properties, such as, for example, the ability to be distributed on the skin or the ability to be absorbed into the skin, and are furthermore distinguished by very good light protection effectiveness and, at the same time, excellent skin care data.

It was particularly surprising that the skin moisturizing performance of these preparations is higher than the same preparations which do not contain sucrose esters. A measure of the skin moisturizing performance in the sense of the present invention is, for example, the results of comeometer measurements.

The invention also provides light-protective cosmetic or dermatological preparations, characterized in that they contain synergistic combinations of substances

(a) one or more sucrose esters and

(b) contain at least one UV filter substance, selected from the group of asymmetrically substituted triazine derivatives, the UV protection performance of these preparations being higher than the same preparations which do not contain any substances according to (a).

A measure of the UV protection performance in the sense of the present invention is, for example, the sun protection factor (SPF or SPF). The cosmetic and dermatological preparations in the sense of the present invention do not leave a greasy or sticky impression on the skin, are extremely skin-friendly and, furthermore, are surprisingly distinguished by the fact that they are sand-repellent.

The invention therefore also relates to sand-repellent cosmetic or dermatological sunscreen preparations, characterized in that they (a) one or more sucrose esters and

(b) contain at least one UV filter substance selected from the group of asymmetrically substituted triazine derivatives.

Preferred sucrose esters for the purposes of the present invention are esters of fatty acids and sucrose (sometimes also called “sucrose” in this document), simply to completely esterified, and commercially available cosmetic raw materials containing the same.

where R ¹ to R ^{8 can} advantageously be selected independently of one another from the group consisting of hydrogen atoms and branched and unbranched alkanoyl groups with 1 to 24 carbon atoms. It is particularly advantageous if up to seven of the radicals R ¹ to R ^{8 are} hydrogen atoms and one up to eight of the radicals R ¹ to R ^{8 are} selected from the group of branched and unbranched alkanoyl groups with 8 to 20 carbon atoms. ,

Particularly preferred sucrose esters are sucrose tetrastearate triacetate, sucrose laurate, sucrose dilaurate, sucrose stearate, sucrose distearate, sucrose caprylate, sucrose myristate, sucrose pa- imitate, sucrose oleate, sucrose behenate, sucrose or sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose / sucrose-sucrose / sucrose-sucrose / sucrose-sucrose / sucrose-sucrose.
