The invention relates to novel hydrated lamellar phases or liposomes which contain either polyethylenimine, or a substance which stimulates intracellular penetration selected from the group consisting of: These liposomes are very useful in cosmetics or in pharmacy for stimulating the intracellular penetration of a substance or active principle.

Hydrated lamellar phases or liposomes which contain a fatty monoamine or a cationic polymer which promotes intracellular penetration, and a cosmetic or pharmaceutical composition containing same, as well as a method of screening such a substance

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.

Substance for restoring normal co-expression and interaction between the LOX and NRAGE proteins

The present invention relates to a process for the preparation of nanoparticulate zinc oxide in the form of aqueous suspensions or in the form of pulverulent solid. Furthermore, the invention relates to the use of zinc oxide particles and suspensions prepared in this way in cosmetic sunscreen preparations, as stabilizer in plastics, in paints, in coatings and as antimicrobial active ingredient.

Process for the preparation of nanoparticulate zinc oxide

The present invention relates to surface-modified nanoparticulate metal oxides where the metal is chosen from the group consisting of aluminum, cerium, iron, titanium, zinc and zirconium, wherein the surface modification comprises a coating with a copolymer P comprising, as monomers,

Surface-modified metal oxides prepared by precipitation in the presence of a copolymer having N-vinylamide units, production processes and use thereof in cosmetic preparations

The present invention relates to the modification of surface properties of particulate, linear, sheet-like, or three-dimensional structures using alkoxylated polyvinylamines. The invention further relates to novel alkoxylated polyvinylamines, and also to a process for their preparation.

Use of alkoxylated polyvinyl amines for the modification of surfaces

The present invention relates to the formation of surface treated zinc oxide and titania particles, and in particular zinc oxide and titania nanoparticles, with a siloxane star-graft copolymer coating, comprising a looped and/or linear polymeric structure on a star-graft copolymer coating, on a particle surface to control the interfacial surface interactions between the particle and the oil phase of the cosmetic skin formulation.

Cosmetic formulations comprising ZnO nanoparticles

The present invention relates to a particulate, linear, sheet-like or three-dimensional structure comprising, at least on its surface, a hydrophilicizing amount of at least one acylated polyamine, where at least some of the polyamine nitrogen atoms bear acyl radicals of the formula IR&#x2014;CO&#x2014;&#x2003;&#x2003;(I)where Ris hydrogen, C&#x2013;C-alkyl, C&#x2013;C-alkenyl or C&#x2013;C-aryl, and where the alkyl, alkenyl and aryl groups may bear at least one substituent selected from the class consisting of hydroxyl, alkoxy, alkoxycarbonyl and NEE, where Eand Emay be identical or different and are hydrogen, alkyl or acyl, to the use of acylated polyamines for modifying the surface properties of solids, and also to a process for modifying the surface properties of particulate, linear, sheet-like, or three-dimensional structures.

Use of acylated polyamines for the modification of surfaces

The invention relates to a method of in vitro testing of the efficacy of a potentially active substance comprising monitoring the effect of said potentially active substance on an artificial skin, comprising a composite product forming a collagen support comprising at least one porous collagen layer covered on at least one side with a collagen membrane component selected from the group consisting of a collagen membrane prepared by compression of a collagen sponge at a pressure of at least about 50 bar and of a collagen membrane comprising a collagen film prepared by drying a collagen gel separately from the porous collagen layer, thereby providing a reliable method for finding new potentially active substances.

Support with collagen base for tissue engineering and manufacture of biomaterials
