The present invention relates to the use of active substances that increase the activation threshold of immune cell as an active principle for the preparation of a cosmetic or pharmaceutical composition, especially a dermatological composition. The invention also relates to a method for screening such active substances.
摘要:
The present invention relates to microcapsule dispersions comprising microcapsules in a hydrophobic solvent, wherein the microcapsules have a capsule core, comprising at least one water-soluble organic substance in solution in a hydrophilic solvent, and a capsule shell, obtainable bya) interfacial polyaddition of at least one di-, oligo- and/or polyisocyanate with at least one reagent carrying at least one isocyanate-reactive group andb) subsequent aftertreatment of the primary product microcapsules with at least one compound selected from the group consisting of amines, alcohols and amino alcohols having a molecular weight of at least 150 g/mol andc) if appropriate, subsequent aftertreatment with at least one further aftertreatment reagent.
摘要:
a cell culture device is disclosed having at least one cell-supporting layer of porous material obtained by dehydration of an aqueous gel which is poured directly either into said well bottom or into the bottom of a cradle or insert of a size which is adapted for being insertable into the volume of the well, thereby enabling by a robot or an automaton itself commanded by you computer.
摘要:
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.
摘要:
The invention concerns active substances modulating the expression of the receptors of the products of the POMC gene (MC-IR, MC-2R, and the μ opioid receptor), and possibly modulating the expression of POMC in cutaneous cells, notably to modulate the proliferation and differentiation of epidermal cells in order to re-epithelial, maintain innervation, irrigate the skin, or restore normal pigmentation, or to fight against aging, or to modulate pigmentation independently or not of cutaneous aging. The invention also concerns a method of screening such active substances.
摘要:
The present invention relates to a method for producing cosmetic preparations comprising metal oxide, where the reaction mixture which forms during the production of the particulate metal oxide is incorporated into the cosmetic preparations essentially without further work-up.
摘要:
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.
