Abstract:
An oil-in-water nanoemulsion in which the oil globules have a mean size of less than 100 nm and which contains an amphiphilic lipid component containing at least one non-ionic amphiphilic lipid which is liquid at an ambient temperature of less than 45.degree. C. The nanoemulsion can be used in the fields of cosmetics and dermopharmaceuticals. The nanoemulsion is stable on storage, can contain significant amounts of oil while retaining good transparency, and can contain heat-sensitive active agents.
Abstract:
Disclosed herein are cosmetic compositions comprising (a) at least one ethylenically unsaturated polymerizable compound and (b) at least one photoinitiator system comprising at least one photoinitiator having at least one absorption wavelength greater than about 350 nm. Also disclosed herein are methods of making up and/or enhancing the appearance of a keratinous substrate comprising (1) forming at least one film on the keratinous substrate by applying said cosmetic composition to the keratinous substrate and (2) exposing the film to UV-LED radiation.
Abstract:
The present invention relates to a method for the cosmetic treatment of a keratin material comprising at least the steps of: (a) having available a lyophilizate containing at least one live or inactivated, physiologically acceptable microorganism, one of its metabolites or one of its fractions and at least one surfactant with an HLB greater than or equal to 12, (b) having available a physiologically acceptable medium, separate from the said lyophilizate, (c) bringing the said lyophilizate extemporaneously into contact with the said medium under conditions favorable for the solubilization and/or dispersion of the said lyophilizate in the said medium, and (d) bringing the mixture obtained in the preceding step into contact with the said keratin material. It further relates to a lyophilizate as defined above.
Abstract:
The invention provides synergistic aqueous compositions comprising at least one flavonoid, and ferulic acid, and optionally one or more additional antioxidants, for cosmetic use.
Abstract:
Novel double-stranded RNA oligonucleotides are useful for decreasing tyrosinase expression, have cosmetic and/or pharmaceutical applications, for example are useful skin depigmenting or anti-browning agents, and can be associated with cationic particles less than or equal to 1 μm in size, having a zeta potential of from 10 to 80 mV.
Abstract:
A foundation composition in the form of a water-in-oil emulsion comprising a fatty phase; an aqueous phase; at least one silicone surfacant chosen from C8-C22 alkyl dimethicone copolyols; and at least 5% by weight, relative to the total weight of the composition, of hydrophobic coated pigments; provided that the composition is free of polyglyceryl-4 isostearate or comprises polyglyceryl-4 isostearate in a quantity such that the weight ratio of the C8-C22 alkyl dimethicone copolyol to the polyglyceryl-4 isostearate is greater than or equal to 2:1, wherein the foundation composition can exhibit good stability at room temperature and can be easy to apply to the skin.
Abstract:
The present invention relates to a composition, especially a cosmetic and/or dermatological composition, containing, in a physiologically acceptable medium, a combination of at least one monosaccharide chosen from mannose, rhamnose and a mixture thereof, and of at least one antioxidant. The present invention also relates to the use of such a composition.
Abstract:
Sunscreen compositions having increased SPF contain at least one aqueous phase, at least one organic UV screening agent and/or at least one inorganic UV screening agent, notably at least one wetting agent, and an effective SPF-increasing amount of concave or annular particles of a silicone material, formulated into a physiologically acceptable medium therefor.
Abstract:
The present invention relates to a composition comprising an oil-in-water emulsion, wherein the emulsion comprises oily globules which are each provided with a lamellar liquid crystal coating and are dispersed in an aqueous phase, wherein each oily globule comprises at least one compound which is agriculturally active, and is individually coated with a monolamellar or oligolamellar layer comprising: (1) at least one non-ionic lipophilic surface-active agent, (2) at least one non-ionic hydrophilic surface-active agent and (3) at least one ionic surface-active agent, wherein the globules having a mean particle diameter of less than 800 nanometers.
Abstract:
