摘要:
The invention relates to a composition in the form of an emulsion comprising a continuous aqueous phase and a dispersed fatty phase, characterized in that said aqueous phase contains liposomes in the presence of a non-ionic surfactant chosen from fatty alcohol polyethylene glycol ethers and fatty alcohol polypropylene glycol ethers, and mixtures thereof, and of at least one polysaccharide in water-soluble form.It also relates to a method for preparing this composition.It also relates to a stable dispersion of liposomes that can be used for the preparation of the aqueous phase of this composition.
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 compressed powder product (60) intended for cosmetic use comprises at least one string of alphanumeric characters (24) displayed essentially throughout said usable thickness h and forming a message that is intended to inform the user of said product about at least one commercial, technical or regulatory characteristic of said product, said characters themselves consisting of a cosmetically acceptable substance, preferably also a compact powder, and being visually distinct from the rest of said product so that said message remains legible on the surface of said product during use, thereby implementing a method of informing the user about the cosmetic product.
摘要:
at least one aurone or a natural or synthetic derivative of aurone, or an analogue of aurone, in which the independent phenyl ring can be substituted by a heterocycle of pyrrole, imidazole, triazole, pyridine, furan, or thiophene type, is disclosed as a cosmetic agent, or as an active substance, for the manufacture either of a cosmetic composition, or of a pharmaceutical composition, notably a dermatological composition, having a melanogenesis-inhibiting activity or a depigmenting activity, or an anti-tyrosinase activity.
摘要:
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: i) a fatty monoamine of carbon-containing chain length of between C10 and C18; ii) a cationic polymer, optionally at least one fluorescent compound which is essentially inert with respect to the intracellular penetration, which enables this penetration to be visualised. These liposomes are very useful in cosmetics or in pharmacy for stimulating the intracellular penetration of a substance or active principle.
摘要:
Cosmetic and pharmaceutical compositions comprising amphiphilic or hydrolipidic complexes of plant proteins modified with fatty chains are presented. The modified proteins are obtained from the reaction carried out at a temperature between ambient temperature and 80° C. with plant proteins having an average molecular mass is greater than or equal to 10,000 Daltons and one or more fatty chains whose carbon atom number is between 4 and 30, selected from fatty acid anhydrides and fatty acid halides, with the exclusion of undecylenic acid.
摘要:
Non-hydroxyalkylated cyclodextrins are disclosed wherein at least one primary alcohol function (CH2OH) is substituted, the —OH portion being replaced by a substituent with formula —O—CO—R or —NR1R2, where: R, R1 and R2 independently represent a linear or cyclic, saturated or unsaturated, hydroxylated or non-hydroxylated alkyl group containing 1 to 30 carbon atoms, preferably 1 to 22 carbon atoms, more preferably a fatty chain containing 2 to 22 carbon atoms. These cyclodextrins are used as vectors for at least one active ingredient, in particular to encourage tissue penetration, in a cosmetic application, or for the production of pharmaceutical compositions, in particular dermopharmaceuticals.
摘要:
The invention relates to a flavonoid ester. This flavonoid ester results from the reaction product of at least one flavonoid selected from the group consisting of a flavonoid with a ketone group in the 4-position, a salt, ester or ether of such a flavonoid, and a C-heteroside and/or O-heteroside derivative of such a flavonoid, with the proviso that this flavonoid contains at least one free alcohol group, with an organic monoacid having from 3 to 30 carbon atoms. These flavonoid esters constitute useful active principles for the manufacture of cosmetic, dermopharmaceutical, pharmaceutical, dietetic or agri-foodstuff compositions.

摘要:
The invention relates to particles. These particles comprise, at least on the surface, a wall formed of plant proteins crosslinked particularly by means of interfacial crosslinking between the plant proteins and an acylating polyfunctional crosslinking agent comprising at least two acylating groups, covalent bonds being formed between the acylatable groups of the proteins and the acyl groups of the acylating polyfunctional crosslinking agent. These particles are used for the manufacture of a cosmetic, pharmaceutical, dermatological or food composition.
