Abstract: The present invention relates to a novel composition based on hydrated lipidic lamelar phases or on liposomes and to a cosmetic or pharmaceutical, particularly dermatological composition incorporating it. The hydrated lipidic lamelar phases or the liposomes contain at least in part a derivative of labdane, or a plant extract containing it. The invention reduces hair drop and promotes regrowth of hair and also prevents gray hair from appearing and provides a treatment for gray hair.

Abstract: The invention relates to cosmetic or pharmaceutical, particularly dermatological, compositions. More particularly, the invention relates to the utilization of an extract of Coleus Esquirolii, Coleus Scutellariodes or Coleus Xanthanthus or one of the mixtures thereof for the preparation of cosmetic or pharmaceutical, particularly dermatological, composition. In particular, the invention helps to efficiently promote skin or hair pigmentation.

Abstract: A process and apparatus are provided for making solid particles from an ionically cross-linkable material by cross-linking drops of the material with a cross-linking agent in the form of a falling stream. In one embodiment, a stream of the cross-linking agent flows down the inner walls of an enclosure and drops of the material are directed to the stream of cross-linking agent. In another embodiment, a stream of the cross-linking agent is free-falling by gravity in a cascade without contacting any surface and drops of the material are directed to the stream of cross-linking agent. Solid particles are separated from the cross-linking agent at about the bottom of the enclosure or at about the bottom of the cascade. The drops of cross-linkable material are directed at the stream of cross-linking agent preferably at an angle of incidence of less than 90.degree. such as between 5.degree. and 45.degree. and most preferably between 15.degree. and 30.degree.. Particles having a size of 10 .mu.

Abstract: The invention relates to the use of an extract of Cyperus, in particular Cyperus rotundus L. for the preparation of a cosmetic or pharmaceutical composition, especially dermatological composition, intended for promoting the pigmentation of the skin or hair and/or for treating pigmentation disorders.

Abstract: A method of treating skin or hair for promoting pigmentation wherein a xanthine component, in an amount effective to promote pigmentation, is incorporated in liposomes or hydrated lipidic lamellar phases.

Abstract: A composition having anti-inflammatory, anti-allergic or anti-aging activity comprising hydrated lipidic lamellar phases or liposomes containing an extract of Scutellaria and a method for treating inflammation, allergies or aging by topical administration of the composition.

Abstract: The present invention relates to the use of an .alpha.-tocopherol phosphate, especially in its dl or d form, or an ester thereof, of the general formula ##STR1## in which: R.sub.1 is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as the methyl or ethyl radical in particular, or an .alpha.-tocopheryl radical; and R.sub.2 is a hydrogen atom, an alkyl radical having from 1 to 4 carbon atoms, such as a methyl or ethyl radical in particular, or an oxyethylene chain of the formula ##STR2## in which R.sub.3 and R.sub.4 independently are a hydrogen atom or a methyl radical and n is an integer greater than or equal to 1, or a salt thereof, for preparing a pharmaceutical, dermatological or cosmetic composition for the prevention or treatment of allergic manifestations such as skin allergy or bronchial asthma, or inflammatory manifestations, or for the prevention or treatment of the harmful effects of free radicals.

Abstract: The present invention relates to a novel composition based on hydrated lipidic lamelar phases or on liposomes and to a cosmetic or pharmaceutical, particularly dermatological composition incorporating it.According to the invention, the hydrated lipidic lamelar phases or the liposomes contain at least in part a derivative of labdane, or a plant extract containing it.The invention makes it possible to reduce hair drop and to promote regrowth of hair and also makes it possible to prevent gray hair from appearing or to treat gray hair.

Abstract: The invention relates to a process for producing organized powders. The powder comprises a set of core particles and a set of satellite particles. To form the organized powders, a substantially homogenous dispersion of each set is made in a dispersing liquid; the resultant dispersion is then sprayed in suitable conditions to form the organized powder. The organized powders obtained are characterized by a very uniform covering of the core particles regardless of their shape.

Abstract: Compositions, for example cosmetic or pharmaceutical compositions, and methods of increasing melanin formation on the skin or scalp employ liposomes including between 0.001 and 10 weight percent, with respect to the total weight of the composition, of tyrosine or a tyrosine derivative selected from the group consisting of an alkali metal salt of L-tyrosine, an alkaline earth metal salt of L-tyrosine, methyl L-tyrosinate, ethyl L-tyrosinate, and stearyl L-tyrosinate.

Abstract: The invention relates to a cosmetic or pharmaceutical composition, containing hydroquinone and kojic acid or a derivative thereof, especially the salts or esters thereof. The hydroquinone and/or kojic acid component is in a form which is at least partially incorporated into liposomes.The combination of these components in liposomes makes it possible to obtain a synergistic effect in their use as topical formulations, especially dermatological or cosmetic compositions, especially for their skin-lightening activity.

Abstract: Compositions based on hydrated lipidic lamellar phases or liposomes are disclosed containing at least in part at least one ecdysteroid or ecdysteroid derivative, in particular ecdysterone, or a plant or animal extract containing the said ecdysteroid or ecdysteroid derivative. Cosmetic or pharmaceutical compositions can be prepared as well as compositions for sericulture or a phytosanitary composition.

Abstract: A composition comprising hydrated lipidic lamellar phases of liposomes containing a mulberry component. The composition may also contain kojic acid or its salts or esters, hydroquinone, or a mixture of kojic acid or its salts or esters and hydroquinone. This composition has skin-lightening properties or anti-inflammatory activity and has pharmaceutical and cosmetic applications. A method for lightening the skin or for applying anti-inflammatory formulation to the skin by applying to the skin a composition comprising hydrated lipidic lamellar phases or liposomes containing a mulberry component.

Abstract: This invention relates to a composition comprising hydrous lipidic lamellar phases or liposomes containing, as an active agent a retinoid or a structural analogue of retinoid, such as a carotenoid or tretinoin. These compositions are more efficient against acne and less irritant for the skin and they are used as a pharmaceutical composition, notably dermatological or cosmetic.

Abstract: The invention concerns a method of homogenizing dispersions of hydrated lipidic lamellar phases and suspensions obtained thereby which can be applied particularly to the making of products intended for cosmetic, pharmaceutical and medical uses.The method consists in dispersing in a dispersion liquid a lipidic phase or a lipidic lamellar phase containing one or several amphiphilic lipids and then in homogenizing the said dispersion by feeding the same under a pressure comprised between 10,000 and 70,000 kPa into a passageway of small width defined between the walls of an orifice and the edges of an obturating element arranged in the section of the orifice adjustably, against the flow of the dispersion.

Abstract: The invention relates to a method for preparing a pulverulent mixture of amphiphilic lipidic constituents and possibly of hydrophobic constituents, as well as to a method for producing hydrated lipidic lamellar phases from the pulverulent mixture.The method comprises dissolving the amphiphilic lipidic constituents and the hydrophobic constituents in an appropriate solvent and then atomizing said solution in a flow of gaseous fluid to produce the pulverulent mixture. The mixture thus obtained is a homogeneous and very fine powder which can be very easily dispersed in a suitable aqueous dispersion medium to produce either slightly hydrated lipidic lamellar phases or highly hydrated lipidic lamellar phases such as liposomes useful in the pharmaceutical and cosmetic fields.
