Sunscreen composition including a combination of a linear ultraviolet radiation absorbing polyether that includes a covalently bound UV-chromophore, and at least one non-polymeric UV-screening compounds.

Sunscreen compositions containing a combination of a linear ultraviolet radiation-absorbing polyether and other ultraviolet-screening compounds

Disclosed are cosmetic or pharmaceutical composition comprising a UV filter combination of

Mixtures of cosmetic UV absorbers

A cosmetic or dermatological composition comprising: a) at least one merocyanine of formula (1) or (2)  b) at least one oily phase comprising at least one alkyl or alkylene carbonate is provided. Also provided is a non-therapeutic cosmetic process for caring for and/or making up a keratin material, comprising applying to the surface of the keratin material, of at least one of the above compositions. Also provided is a non-therapeutic cosmetic process for limiting the darkening of the skin and/or improving the colour and/or uniformity of the complexion, comprising applying to the surface of the keratin material, of at least one of the above compositions. In addition, provided is a non-therapeutic cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising applying to the surface of the keratin material, of at least one of the above compositions.

Cosmetic or dermatological composition comprising a merocyanine and an oily phase comprising at least one alkyl or alkylene carbonate

The present invention relates to a cosmetic and/or dermatological composition comprising in a physiologically acceptable medium at least one merocyanine derivative of formula (1) or (2) and/or its E,E-, E,Z- or Z,Z-geometrical isomer forms: comprising specific polar groups consisting of hydroxyl- and ether-functionalities. Another object of the present invention relates to a cosmetic process for controlling and/or improving the darkening of the skin under exposure to UV radiation and the homogeneity of the colour of the complexion which comprises the application onto the skin of a cosmetic composition as above defined. Another object of the present invention relates to a cosmetic process for protecting the keratinic materials and particularly the skin against photo-ageing which comprises the application onto the keratinic material of a cosmetic composition as above defined. 

Cosmetic and/or dermatological composition containing a merocyanine derivative comprising specific polar groups consisting of hydroxyl- and ether-functionalities

The present invention relates to a photoprotective composition for topical use comprising, in a cosmetically acceptable medium, at least one dibenzoylmethane derivative compound, at least one merocyanine compound and at least one compound capable of accepting the triplet excited level energy of said dibenzoylmethane derivative compound(s). The invention also relates to the use of at least one compound capable of accepting the triplet excited level energy of said dibenzoylmethane derivative compound(s), for photostabilizing with respect to UV radiation a composition comprising at least one dibenzoylmethane derivative compound and at least one merocyanine compound.

Photoprotective compositions comprising a dibenzoylmethane derivative, a merocyanine compound and a compound capable of accepting the triplet excited level energy of the dibenzoylmethane compound

Disclosed is the use of a UV filter combination, comprising (a) a first UV filter selected from benzylidene malonates of formula (1), wherein Rmethyl; ethyl; propyl; or n-butyl; if Ris methyl, then R is tert. butyl; formula (II); formula (III); a radical of formula (1a); or a radical of formula (1b); wherein Rand R, independently from each other are hydrogen; or methyl; Ris methyl; ethyl; or n-propyl; Rand Rindependently from each other are hydrogen; or C-Calkyl; if Ris ethyl; propyl; or n-butyl, then R is isopropyl; and (b) a second UV filter selected from (b) Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine; (b) Butyl Methoxydibenzoylmethane; (b)Diethylhexyl Butamido Triazone; (b) Ethylhexyl Triazone; (b) Diethylamino Hydroxy Benzoyl Hexyl Benzoate; (b) Ethylhexyl Methoxycinnamate; (b) Ethylhexyl Salicylate; (b) Homosalate; (b) Octocrylene; (b) micronized Methylene Bis-Benzotriazolyl Tetramethylbutylphenol; (b) Phenylbenzimidazole Sulfonic Acid; (b) Titanium Dioxide; (b) micronized Tris-Biphenyl Triazine; and (b) micronized (2-{4-[2-(4-Diethylamino-2-hydroxy-benzoyl)-benzoyl]-piperazine-1-carbonyl}-phenyl)-(4-diethylamino-2-hydroxy-phenyl)-methanone;(b) benzoicacid,4,4-[[3-[1,3,3,3-tetramethyl-1-[trimethylsilyl)oxy]-1-disiloxanyl]propyl]amino]-1,3,5-triazine-2,4-diyl]diimino]bis-, dibutyl ester wherein the UV filter combination comprises at least 2 UV filters of component (b)-(b); for the protection of human and animal hair and skin against UV radiation. 

UV filter combinations comprising benzylidene malonates

Disclosed is the Use of UV absorbers selected from (a) diphenylacrylates; and (a) specific hydroxyphenyl triazines for stabilizing cosmetic compositions comprising an organic UV absorber selected from (b) a specific benzophenone derivative, (b) a specific benzotriazole derivative and (b) a specific triazine derivative and UV filters selected from (c) cinnamic acid derivatives; and (c) dibenzoylmethane derivatives.

Stabilization of cosmetic compositions

Disclosed is the use of an aqueous dispersion comprising (a) a micronized sparingly soluble organic benzophenone derivative of formula (1), selected from the crystal modifications (B) and (C), wherein the crystal modification (B) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.70; and wherein the crystal modification (C) is characterized by a peak in the X-ray diffraction pattern at a d-spacing of about 7.06; and (b) a dispersing agent selected from anionic, non-ionic and amphoteric surfactants; for protecting the human skin from browning and skin aging. The new crystal modification (C) represents a thermodynamically stable compound of formula (1) at 25&#xb0; C. This modification is therefore suitable in dispersions comprising micro-fine particles.
