The composition comprises of a component A selected from a hydroxylated derivative of benzoic acid or of cinamic acid, their esters, amides or salts, a glycoside of a hexose, and their mixtures; and a component B selected from quinic acid, shikimic acid, their alkaline metal or alkaline earth salts, their methyl esters, and mixtures of the same. This composition is suitable for protecting the skin against ultraviolet radiation coming from the sun or artificial sources, such as those used in phototherapy units and in sun tanning rooms. For application in the field of dermatology and nutrition, and, in particular, in the photoprotection of the skin and mucosa, photo-ageing and photocarcinogenesis, including protection of the immune system associated with the skin.

Photoprotective compositions well suited for the photoprotection of the skin, lips and / or hair against the damaging effect of UV-radiation comprise at least one aqueous phase and at least one system for screening out UV-radiation, and which also contain:(a) at least one partially or totally neutralized, crosslinked or non-crosslinked amphiphilic polymer of 2-acrylamidomethylpropanesulfonic acid (AMPS), and(b) at least one water-soluble silicone comprising at least one terminal or pendent monovalent polyoxyalkylene group.

Topically applicable, water-resistant cosmetic or dermatological compositions well suited for the UV-photoprotection of human skin and / or hair comprising an effective UV-photoprotecting amount of: (a) at least one UV screening agent from various classes and particularly effect mixtures thereof; and, (b) at least one random terpolymer; and, optionally, (c) other cosmetically acceptable ingredients. The various classes of UV-protecting compounds or UV sunscreens of special interest are selected from the groups b1 sparingly soluble micronized organic UV absorber, b2 Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, b3 at least one oil soluble organic UV absorber,b4 at least one inorganic UV absorber and b5 at least one water soluble UV absorber further defined herein. The present invention also relates to personal care compositions comprising at least one random terpolymer and other cosmetically acceptable ingredients.

The molecules capable of absorbing ultraviolet radiation from the cashew nut shell liquid changes are the object of the present invention; it is also described the compositions responsible for protecting the surfaces and chemical processes for the referred molecules production.

A cosmetic composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, a water-insoluble powdered polymer of porous particles having an Oil Absorbance (castor oil) Value ranging from about 90 to about 500 ml / 100 gm, and a cosmetically acceptable carrier. The composition exhibits an excellent soft focus property to hide skin imperfections, and retains relatively high SPF photoprotection.

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

The present invention relates to highly stable water-in-oil sunscreen emulsions that provide a high sunscreen efficiency (“SE”) having a sun protection factor (“SPF”) of X, where X is at least about 15, and having a sunscreen efficiency (“SE”) of at least 2, preferably at least 3, where SE is the ratio of SPF over the total weight percentage of sunscreen actives based on the total weight of the composition. The emulsions of the present invention provide photoprotection for the period corresponding to the labeled SPF throughout the period of exposure to natural sunlight and comprises (i) at least one sunscreen active and (ii) an alkyl dimethicone copolyol emulsifier in which the water-soluble, alkyl-soluble and silicone-soluble groups of the dimethicone copolyol are in specific ratios to each other. Preferably, the high SE water-in-oil emulsion comprises both a UV-A sunscreen and UV-B sunscreen. More preferably, the combination of sunscreen actives is photostable.

Stable photoprotective cosmetic emulsions, notably water-in-oil emulsions well suited for the UV-photoprotection of the skin, lips, mucous membranes and / or hair, contain at least one aqueous phase, at least one oily phase, an effective UV-photoprotecting amount of at least one coated or uncoated metal oxide UV-blocking agent and an effective stabilizing amount of at least one amphiphilic oligomer or polymer derived from a polyolefin which also comprises at least one polar moiety, formulated into a physiologically acceptable medium therefor.

A cosmetic water-in-oil emulsion composition is provided which includes composite particles of a sunscreen agent and a condensation polymerized polyamide binder, an emulsifying silicone surfactant sufficient to form the water-in-oil emulsion, an oil phase, and a water phase. The composition exhibits relatively high SPF photoprotection while maintaining excellent soft focus properties that hide skin imperfections.

The invention relates to topically applicable novel cosmetic / dermatological sunscreen composition, especially suited for the enhanced UV-photoprotection of human skin and / or hair. This composition contains (i) at least a silicone derivative having a benzotriazole functional group as the first shielding agent, (ii) at least a dibenzoylmethane derivative as the second shielding agent, and (iii) at least an amino- substituted 2-hydroxybenzophenone derivative represented by formula (III) as a third shielding agent. The combination of the three UV-screening compounds results in a synergistic effect. The invention also relates to the use of the composition for the photoprotection of the skin and / or hair against the deleterious effects of ultraviolet radiation.
