Abstract: The subject of the invention is the use of an extract of Stevia in combination with a salt, for masking the bitterness of bitter compounds in cosmetic or dermatological compositions. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the compound permanently without changing the nature of the fragrance or the colour of the composition.

Abstract: The subject of the invention is the use of a sweetener such as sucralose or an extract of Stevia, for masking the bitterness of hydrophilic organic UV-screening agents in cosmetic or dermatological compositions. The sweetener may advantageously be used in combination with a mint aroma or a salt, for example sodium chloride. This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the hydrophilic UV-screening agent without changing the nature of the fragrance or the colour of the composition.

Abstract: The invention relates to a perfuming solution comprising a volatile alcohol, a perfume and a mixture for stabilizing said perfume consisting of at least one UV filter selected from the derivatives of cinnamate, at least one UV filter selected from the derivatives of dibenzoylmethane, and at least one non-volatile oil that is soluble in said alcohol and is a solvent for said filters, the stabilizing mixture being in sufficient amount to protect the perfuming solution from degradation by UV radiation.

Abstract: The invention relates to an additive comprising at least 95 wt. % of a mixture consisting of at least one organic filter filtering UVA, at least one organic filter filtering UVB, and from 1 to 50 wt. % of at least one non-volatile oil that is a solvent for said filters. This composition is particularly useful as an agent for protecting the organoleptic properties of a transparent cosmetic composition, against UV radiation.

Abstract: The invention relates to the stimulation of the synthesis and of the activity of an isoform of lysyl oxidase, and more particularly of the LOXL (lysyl oxidase-like) isoform. The invention relates notably to a method of identifying an active principle which stimulates the formation of elastic fibers. The aim of the invention is mainly to provide such a method of identification so as to provide compositions which enable stimulating the formation of elastic fibers.

Abstract: The invention relates to a cosmetic composition for making up the skin, lips or superficial body growths, comprising a cosmetic base, at least one coloured inorganic pigment [A] in an amount sufficient to define a first colour of said composition in its body, and at least one pigment [B] chosen from organic dye lakes, the colour of which is different from that of the pigment [A], in an amount sufficient to define a second colour, radically different from said first colour, which is revealed after the application of said composition on the lips, skin or superficial body growths.

Abstract: The invention relates to a solid cosmetic composition, in the form of a loose or compact powder, comprising: (a) from 50% to 99% by weight of at least one particulate solid phase, (b) from 0.5% to 50% by weight of at least one non-volatile liquid phase, and (c) from 0.01% to 4% by weight of at least one block copolymer obtained from a first monomer of 2-acrylamidomethylpropanesulphonic acid and from a vinyl second monomer having a nitrogenous cyclic side chain. The invention also relates to a process for manufacturing such a composition, which comprises: (i) mixing the particulate solid phase, the non-volatile liquid phase, the block copolymer and water so as to obtain a slurry, (ii) suctioning off the water present in the slurry so as to obtain a dry powder.

Abstract: A method of testing a substance potentially active in the field of lipolysis comprising: preparing a substrate containing at least one triacylglycerol; placing this substrate in contact with a substance potentially active in the field of lipolysis, and with a lipoprotein lipase, in the presence of a cofactor of lipoprotein lipase, for a period of time sufficient to release at least in part one fatty acid of the triacylglycerol; and determining the capacity of inhibition of the release of the fatty acid resulting from the activity of the lipoprotein lipase, under the action of said potentially active substance, and evaluating the result of the inhibition which is either compared to the result obtained in the absence of the potentially active substance tested or compared with the result obtained in the presence of a known inhibitor acting as reference. Cosmetic and pharmaceutical uses are described.

Abstract: The disclosed substance restores normal co-expression and interaction between the LOX and NRAGE proteins. Particularly, an effective amount of the substance that modulates the expression and/or activity of LOX of SEQ ID NO: 1 and/or that modulates the expression and/or activity of NRAGE of SEQ ID NO: 2, may be used for the manufacture of a composition for modulating the interaction between the LOX and NRAGE proteins to regulate the balance between the cellular phenomena of proliferation, differentiation and apoptosis, particularly in cases where the balance between these phenomena is disturbed, and especially in cases where the interaction between LOX and NRAGE is absent or altered. The invention makes it possible especially to treat and/or prevent skin ageing, lichen planus, graft-versus-host reaction (GVH), eczema, psoriasis and a cancer, particularly an epithelial cancer and more particularly a cutaneous epithelial cancer of basocellular or spinocellular type.
