The present invention is directed to a transparent medium incorporating the oxidative polymerization product of 3-hydroxykynurenine, a synthetic version of the yellow-to-brown pigment that occurs in the ocular crystalline lens with age. Because this coloration in the ocular lens is believed to offer photoprotection to the retina, it may represent an ideal sun lens filter with an optical transmission spectrum that is compatible with the psychophysical and neurophysiological characteristics of the vision system.

Topically applicable cosmetic/sunscreen/dermatological compositions, well suited for improved photoprotection of human skin and/or hair against the damaging effects of UV-A and UV-B irradiation and/or for the therapeutic treatment of a disease state of the skin or mucosae, essentially in the absence of photobluing/whitening, comprise at least one titanium dioxide (nano)pigment and an effective photobluing/whitening-reducing amount of deformable hollow particulates (microspheres) having a particle size ranging from 1 mu m to 250 mu m and which comprise an expanded copolymer of vinylidene chloride, acrylonitrile and a (meth)acrylate.

A cosmetic composition is provided which is a vanishing cream structured with 0.5 to 50% by weight of C₁₂-C₂₀ fafty acid, 0.1 to 20% by weight of C₁₂-C₂₀ fatty acid salt and hydrophilic composite particles with organic sunscreen agent. The hydrophilic composite particles are formed as a composite of sunscreen agent and a binder in a relative weight ratio of about 5:1 to about 1:10. The composition exhibits relatively high SPF photoprotection while maintaining excellent skinfeel aesthetics.

An orally administrable composition for the photoprotection of the skin which comprises a photoprotecting effective amount of i) at least one probiotic lactic acid bacterium or a culture supernatant thereof, and ii) at least one yeast, included into an orally acceptable carrier.

An ingestable composition for the photoprotection of the skin of pets which comprises a photoprotecting effective amount of i) at least one probiotic lactic acid bacterium or a culture supernatant thereof, and ii) at least one yeast and/or a carotenoid or derivative, included into an ingestable carrier.

The present invention relates to photostable compositions that provide protection from ultraviolet radiation (“UVR”). The invention particularly relates to the sunscreens avobenzone, octocrylene and oxybenzone, forming a triplet sunscreen combination. Compositions of the present invention are generally substantially free of substantial amounts of other sunscreens. The triplet combination surprisingly provides and substantially maintains the initial SPF value of the sunscreen composition throughout the period of UVR exposure. Compositions of the invention are photostable such that each of sunscreen active in the triplet combination does not appreciably photodegrade. The present invention accurately communicates the amount of UVR photoprotection actually provided in natural sunlight and minimizes the amount of potential harmful free radicals formed as byproducts of photodegradation.

The present invention relates to a new-type beauveria bassiana pesticide suspension. Its composition includes (by wt%) 1-50% of beauveria bassiana powder, 0.05-15% of chitin inhibitor, 0.25-40% of organic silicon surfactant, 0-40% of adsorbing agent, 0-20% of dispersing agent, 0-20% of moistening agent, 0-20% of antioxidant, 0-20% of photoprotection agent, 0-20% of viscosifier and 1-60% of water. Said invention also provides the concrete steps of its preparation method, and its concrete application method.

The invention provides a photoprotection composition as well as a preparation method and application thereof. The composition is prepared from an ultraviolet absorbent, carnosine, sunflower extract, chrysanthellum indicum extract and tocopheryl acetate. According to the photoprotection composition provided by the invention, the carnosine, the sunflower extract, the chrysanthellum indicum extract and the tocopheryl acetate have a synergetic effect and are matched with the ultraviolet absorbent so that the effect of resisting full-wave band optical radiation is realized; the resistance effects on UVA (Ultraviolet A) and UVB (Ultraviolet B) are enhanced and the photoprotection composition has a resisting capability on blue light and infrared light.

Topically applicable, solid UV-photoprotecting compositions suited for the UV-photoprotection and/or makeup and/or care of the lips and/or the face, advantageously shaped as sticks, contain a) at least one fatty phase, a UV-photoprotecting amount of b) at least one organic UV-screening agent and c) a fraction of metal oxide mineral nanopigments, and d) an SPF-increasing amount of at least one octenylsuccinic anhydride-esterified starch salt, formulated into a physiologically acceptable medium therefor.

A meta-stable photoprotective composition, a product including the meta-stable composition, and a method of protecting a keratinous substrate from UV radiation by applying the product are provided. The meta-stable photoprotective composition includes at least one water-in-oil emulsifier having a hydrophilic-lipophilic balance (HLB) of less than 6, at least one non-ionic oil-in-water emulsifier having an HLB of greater than 9, at least one ionic surfactant, and at least one sunscreen active ingredient. The weight ratio of the at least one non-ionic oil-in-water emulsifier to the at least one water-in-oil emulsifier is about 0.2 to about 2.0. The meta-stable composition converts from an oil-in-water (O/W) emulsion to a water-in-oil (W/O) emulsion upon rubbing.

The present invention relates to photostable compositions that provide protection from ultraviolet radiation (“UVR”). The invention particularly relates to the sunscreens avobenzone, octocrylene and oxybenzone, forming a triplet combination. Compositions of the present invention are free of diesters or polyesters of naphthalene dicarboxylic acid and also are substantially free of substantial amounts of other sunscreens and substantial amounts of optimizing agents. Sunscreens of the invention may be essentially free of, or free of, lower monohydric alcohol and/or acrylates/C_12-22 alkylmethacrylate copolymer in an effective non-pilling amount used to gel a C₁-C₄ alcohol. The triplet combination surprisingly provides and substantially maintains the initial SPF value of the sunscreen composition throughout the period of UVR exposure. Compositions of the invention are photostable such that each of sunscreen active in the triplet combination does not appreciably photodegrade. The present invention accurately communicates the amount of UVR photoprotection actually provided in natural sunlight.
