Abstract:
The present invention relates to individualized porous particles, characterized in that they have a volume-average diameter of less than or equal to 10 μm and a specific surface area of greater than or equal to 1 m2/g, and in that they comprise at least one cosmetically or pharmaceutically active compound at least present inside said particles.
Abstract:
A nanoemulsion comprising an oily phase dispersed in an aqueous phase and having oil globules with a number-average size of less than 100 mm, which dispersion is facilitated by a surfactant comprised of polyethylene oxide and polypropylene oxide blocks, the oily phase comprising at least one oil having a molecular weight of greater than 400 and wherein the ratio by weight of the amount of oily phase to the amount of surfactant ranges from 2 to 10.
Abstract:
The present application relates to a transparent oil-in-water emulsion, the oil globules of which have a mean size of less than 100 nm, which comprises at least one silicone surfactant. The emulsion according to the invention is stable on storage and can contain significant amounts of oil while retaining good transparency. It can contain heat-sensitive active principles and can be used in particular in the cosmetics field and in dermatology for the treatment and the care of the skin, mucous membranes, nails, scalp and hair.
Abstract:
The present invention relates to nanoparticles, and in particular nanocapsules, provided with a lamellar coating obtained from a silicone surfactant, and to their use in a composition, in particular a topical composition, for treatment of the skin, mucosae, nails, scalp and/or hair.
Abstract:
The vesicles are prepared from a lipid phase containing a mixture of nonionic amphiphilic lipids consisting of a mixture of esters of at least one polyol chosen from the group composed of polyethylene glycol containing from 1 to 60 ethylene oxide units, sorbitan, sorbitan bearing 2 to 60 ethylene oxide units, glycerol bearing 2 to 30 ethylene oxide units, polyglycerols containing 2 to 15 glycerol units, sucroses, and glucoses bearing 2 to 30 ethylene oxide units and of at least one fatty acid containing a saturated or unsaturated, linear or branched C.sub.5 -C.sub.17 alkyl chain, the number of alkyl chains per polyol group being between 1 and 10, the mixture being stabilized with ionic amphiphilic lipid or lipids chosen from the group composed of those which impart a pH of between 5.5 and 7.5 to the dispersion.
Abstract:
Compositions containing a first dispersion of lipid vesicles which are capable of penetrating into the deep layers of the skin and which contain at least one active agent chosen from lipolytic agents, draining agents and firming agents, for treating these deep layers, and a second dispersion of lipid vesicles which are capable of penetrating into the surface layers of the skin and which contain at least one active agent chosen from cutaneous surface treatment agents, exfoliation agents, smoothing agents and softening agents for the skin, for treating these surface layers, are effective as slimming agents for combating plumpness.
Abstract:
A composition comprising an aqueous dispersion of lipid vesicles encapsulating at least one compound which screens out UV radiation and contains at least one free or at least partially neutralized acidic function, wherein the lipid vesicles have a lipid membrane formed from at least one nonionic amphiphilic lipid (A) or from at least one saturated hydrocarbon ionic amphiphilic lipid (B) having an iodine number of less than 10, and from at least one totally neutralized ionic amphiphilic lipid (C) is disclosed. The use of this composition as a base for products to care for the skin, the scalp, the hair, the eyelashes or the eyebrows, as a base for make-up products, and more particularly as bases for compositions to protect the human epidermis, the hair, the eyelashes or the eyebrows against ultraviolet rays are also disclosed.
Abstract:
Cosmetic or dermatological compositions comprising an oil-in-water type emulsion containing oily globules which are coated with a lamellar liquid crystal coating and are dispersed in an aqueous phase, in which each oily globule contains at least one lipophilic compound which is cosmetically or dermatologically active and is individually coated with a monolamellar or oligolamellar layer of at least one lipophilic surface-active agent, at least one hydrophilic surface-active agent, and at least one fatty acid, the coated oily globules having a mean diameter of less than 500 nanometers, preferably less than 200 nanometers, and the oily phase contains a basic agent in the dissolved state, exhibit good skin and hair penetration.
