Definitions

  • Cosmetic and dermatological light protection formulations containing water-soluble UV filter substances and alkyl naphthalates containing water-soluble UV filter substances and alkyl naphthalates
  • the present invention relates to 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 various 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 is around the maximum of the erythema effectiveness of sunlight 308 nm specified.
  • Numerous compounds are known for protection against UV-B radiation, which are, for example, derivatives of 3-benzyiide camphor, 4-aminobenzoic acid, cinnamic acid, salicylic acid, benzophenone and 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 increased by UV-A radiation.
  • UV-A 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.
  • UV-A filter substances are e.g. B. dibenzoylmethane derivatives, in particular 4- (tert-butyl) -4'-methoxydibenzoylmethane (CAS-Nr. 70356-09-1), which Vaudan of Gi- under the trademark Parsol ® 1789 and from Merck under the trade name Eusolex® 9020 is sold.
  • UV stabilizers such as, for example, ethylhexyl-2-cyano-3,3-diphenylacrylate (octocrylene) or 4-methylbenzylidene camphor.
  • the sunburn or the light erythema are the acute manifestations of the influence of light.
  • the subsequent reaction of the skin also leads to reduced sebum production and drying of the skin.
  • 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. It was surprising and unforeseeable for the person skilled in the art that cosmetic or dermatological preparations which act as sunscreens, characterized in that they
  • R 1 and R 2 are independently selected from the group of branched and unbranched alkyl groups containing 6 to 24 carbon atoms, remedy the disadvantages of the prior art.

  • Such formulations may preferably also be a microemulsion, a solid emulsions (i.e. an emulsion which is stabilized by solids, e.g. a Pickering emulsion), a sprayable emulsion or a hydrodispersion.
  • the preparations according to the invention are extremely satisfactory preparations in every respect, which are not limited to a restricted choice 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 substances
  • R 1 and R 2 are selected independently of one another from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms, the UV protection performance, in particular the UV-A protection performance, of these preparations being higher than the same preparations which contain no substances according to (b).
  • UV protection performance of sunscreens or the UV filters on which they are based is generally determined in biological effectiveness tests under standardized conditions.
  • 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
  • a value is determined that 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 invention also relates to the use of one or more dialkylnaphthalates, which are distinguished by the structural formula
  • R 1 and R 2 are selected independently of one another from the group of branched and unbranched alkyl groups having 6 to 24 carbon atoms, for stabilizing dibenzoylmethane derivatives in cosmetic or dermatological preparations which contain at least one water-soluble UV filter substance, against which by UV radiation induced decomposition.
