摘要:
The invention relates mainly to a particle comprising at least one biopolymer which is degradable under the effect of an electromagnetic wavelength, notably the wavelength of which is in the spectrum of the wavelengths emitted by the sun, this biopolymer comprising nucleosides. The invention also relates to compositions containing such particles with the aim of delivering an active principle.These particles can be used mainly in cosmetics, in dermatology, in pharmacy, in agri-food or en agro-industrials.
摘要:
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.
摘要:
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.

摘要:
This invention relates to the use of a preparation comprising sulfated oligosaccharides which trap spermine or spermidine or both, as an active slimming ingredient in a cosmetic, pharmaceutical and/or nutraceutical composition. One of the objectives of the invention is to supply a cosmetic, pharmaceutical or nutraceutical composition with a slimming effect.
摘要:
A method for tinting, for coloring skin, or for increasing the tanned appearance of skin comprising the use of an extract of a plant from the family of Compositae or Asteraceae, preferably an extract of chicory (Cichorium intybus L.), and a method of screening a plant for the manufacture of a cosmetic composition for coloring, particularly for tinting, at least one part of skin.
摘要:
The invention relates to substances which are capable of protecting FGF-2, to a composition for preventing or controlling degradation of FGF-2, and a method of protecting FGF-2 in the skin from degradation.In particular, the invention relates to an extract of Hibiscus Abelmoschus or ambrette, a rebokza extract, a gougizi berry extract, a banha extract, a lessonia extract, a mustard flour extract, a wooyin extract, a barley extract, and/or a sesame extract, in amounts effective to protect FGF-2 from its degradation.Further, the present invention allows the extracellular matrix to be restructured, particularly at the dermis, which is useful, for example, for controlling aging.
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 invention relates to the use of a Rhodiola crenulata extract, via the topical route, for increasing the energy metabolism of the cutaneous tissues of a subject. The invention relates notably to topical compositions which comprise an active agent for increasing the energy metabolism of the cutaneous tissues of a subject, said active agent being a Rhodiola crenulata extract. The present invention enables making a cosmetic care such as fighting against, or slowing down or preventing the loosening of the cutaneous tissue, increasing the plasticity of the cutaneous tissue, exerting an anti-wrinkle effect or slowing down or preventing the appearance of wrinkles, fighting against, slowing down or preventing the appearance of acne, exerting a depigmenting effect of the cutaneous tissue, in particular of the skin, and promoting desquamation of the cutaneous tissue (or “peeling”).
摘要:
Particles comprising an outer wall formed of one or more saccharide components selected from the group consisting of monosaccharides and oligosaccharides crosslinked by interfacial crosslinking in emulsion, preferably at room temperature, with a polyfunctional acylating crosslinking agent to produce ester linkages between the acylatable hydroxyl group(s) of the primary alcohol(s) of the saccharide component and the acyl groups of the polyfunctional acylating agent. These particles can be used for the manufacture of cosmetic, pharmaceutical and food compositions.
