Abstract

The invention relates to light-protective cosmetic or dermatological emulsions which are characterised in that they contain (a) at least one sucrose ester and (b) at least one benzotriazole derivative. The invention also relates to the use of said emulsions.

Description

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

The harmful effect of the ultraviolet part of solar radiation on the skin is well known. Depending on their respective wavelength, the rays have different effects on the organ skin: the so-called UV-C radiation with a Wavelength that is less than 290 nm is from the ozone layer in the earth's atmosphere absorbed and therefore has no physiological meaning. In contrast, strah len in the range between 290 nm and 320 nm, the so-called UV-B range, an Ery them, a simple sunburn or even more or less severe burns As a maximum of the erythema effectiveness of the sunlight the narrower Be richly stated around 308 nm.

To protect against UV-B radiation, numerous compounds are known in which it are, for example, derivatives of 3-benzylidene camphor, 4-aminobenzoic acid, cinnamic acid, salicylic acid, benzophenone and s-triazine.

It has long been erroneously assumed that the boring UV-A radiation with a wavelength between 320 nm and 400 nm only a negligible biological effect. However, numerous studies have now shown that UV-A radiation with a view to triggering photodynamic, especially phototoxic Reactions and chronic changes in the skin are far more dangerous than UV-B  Radiation is. The damaging influence of UV-B radiation from UV-A Radiation to be amplified.

So it is u. a. proved that even UV-A radiation occurs under normal everyday conditions conditions are sufficient to damage the collagen and elastin fibers within a short time conditions that are essential for the structure and firmness of the skin. here this leads to chronic light-related skin changes - the skin "ages" prematurely. The clinical appearance of light-aged skin includes for example folds and wrinkles as well as an irregular, furrowed relief. Further the areas affected by light-induced skin aging can cause an irregular pigment have mentation. The formation of brown spots, keratoses and even kar Zinoma or malignant melanoma is possible. One through everyday UV exposure prematurely aged skin is also characterized by less activity of the lan gerhans cells and a mild, chronic inflammation.

About 90% of the ultraviolet radiation reaching the earth consists of UV-A Rays. While the UV-B radiation is strong depending on numerous factors varies (e.g. time of year and time of day or latitude), the UV-A radiation remains unaffected depending on the season and time of day or geographical factors day by day relative constant. At the same time, the major part of UV-A radiation penetrates the living Epidermis, while about 70% of UV-B rays go back from the horny layer be.

It is therefore of fundamental importance that cosmetic and dermatological Light protection preparations against both UV-B and UV-A radiation are sufficient provide adequate protection.

In general, the light absorption behavior of light protection filter substances is very high well known and documented, especially in most industrialized countries positive lists for the Use of such substances exist, which are quite strict standards for the documentation create mentation.

The use concentration of light protection filter substances known as solids is often limited - especially in combination with other substances to be dissolved.  It therefore creates certain technical difficulties, higher light to achieve 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

• - regreasing and moisturizing agents,
• - anti-inflammatory and cooling substances,
• - locally anesthetic substances and / or
• - disinfectants to prevent possible skin infections.

These so-called aftersun or après-soleil preparations are intended for the skin to cool after sunbathing and to improve their moisture retention, the Communication of the cooling effect plays a central role. However, the stand is lacking the technology on products that already protect the skin during UV radiation protect them from drying out and take good care of them.

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. in application such products on a sandy beach that the sand sticks to the body, which is perceived by the user as unpleasant and, in the worst case, lead to it Ren can that the sunscreen is used too little or not at all. There at the sea there is usually a more or less strong wind, this disadvantage occurs in the Rule even when the body is not in direct contact with the sand comes - for example, when sunbathing on a deck chair - because also in the wind Swirling sand dust sticks to the creamy skin areas.

Another object of the present invention was therefore light protection formulations to find, after their application, no sand sticks to the creamy skin, accordingly, which can be described as sand-repellent.

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

• a) one or more sucrose esters and
• b) at least one benzotriazole derivative

contain,
remedy the disadvantages of the prior art.

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

The emulsions according to the invention are extremely satisfactory in every respect Preparations that are not limited to a limited selection of raw materials. Accordingly, they are particularly suitable as a basis for preparation to serve shapes with diverse applications. The accessories according to the invention Horse shows show very good sensory and cosmetic properties, such as show the distributability on the skin or the ability to draw into the skin, and NEN also stand out due to their very good light protection effectiveness the skin care data.

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

The invention also relates to light-protective cosmetic or dermatological preparations, characterized in that they have synergistic combinations of substances

• a) one or more sucrose esters and
• b) at least one benzotriazole derivative

contain,
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 is in the sense of the present invention, for example the sun protection factor (SPF or SPF).  

The cosmetic and dermatological preparations in the sense of the present invention leave no greasy or sticky impression on the skin, are worn out is skin-friendly and surprisingly distinguish itself by 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) at least one benzotriazole derivative

contain.
