Definitions
- 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.
- 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.
- rays in the range between 290 nm and 320 nm, the so-called UV-B range cause an erythema, a 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 and s-triazine.
- 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.
- the damaging influence of UV-B radiation can also be intensified by UV-A radiation.
- UV-A radiation 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 or day or geographical factors. At the same time, the major part of UV-A radiation penetrates the living epidermis, while around 70% of UV-B rays are retained by the horny layer.
- 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.
- 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 using such products 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.
- the preparations can preferably contain, in addition to one or more oil phases, one or more water phases and, for example, in the form of W / O, O / W, W / O / W or O / W / O emulsions .
- Such formulations may preferably also be a microemulsion, a solid emulsion (i.e. an emulsion stabilized by solids, e.g. a Pickering emulsion), a sprayable emulsion or a hydrodispersion.
- the emulsions according to the invention are preferably O / W emulsions.
- 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 spreadability 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.
- the invention therefore also relates to cosmetic or dermatological preparations which have a light protection effect, characterized in that they contain synergistic combinations of (a) at least one benzotriazole derivative and
- UV protective power means both the protective power against UV-A radiation and against UV-B radiation.
- a measure of the UV protection power in the sense of the present invention is, for example, the sun protection factor (SPF or SPF) or also IPD values and the like.
- the sun protection factor indicates the prolongation of sun exposure, which is made possible by using the sunscreen. It is the quotient of erythema threshold time with sunscreen and erythema threshold time without sunscreen.
- the IPD method (IPD ⁇ immediate pigment darkening) is usually used to test UV-A protection. Similar to the determination of the light protection factor, a value is determined which indicates how much longer the skin protected with the light protection agent can be irradiated with UV-A radiation until the same pigmentation occurs as for the unprotected skin.
- the cosmetic and dermatological preparations in the sense of the present invention do not leave a greasy or sticky impression on the skin, are excellently compatible with the skin and are also surprisingly distinguished by the fact that they are sand-repellent.
- the invention therefore also relates to cosmetic or dermatological light protection preparations, characterized in that they
