The nanoemulsion according to the invention comprises an oily phase dispersed in an aqueous phase, having oil globules with a number-average size less than 100 nm, characterized in that it contains a ternary surfactant system comprising: Use in the manufacture of cosmetic, dermatological and ophthalmological compositions.

Translucent nanoemulsion, production method, and uses thereof in the cosmetic, dermatological and/or ophthalmological fields

A solid composition for topical application comprising, in an aqueous phase, a gelling system comprising (i) gellan gum, (ii) at least one other hydrocolloid chosen from the group formed by xanthan gum, carboxymethylcellulose, hydroxypropylcellulose, methylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, agar-agar, carrageenans, alginates, carob gum, guar gum, gum arabic, karaya gum, gum tragacanth, ghatti gum, pectins, gelatin, caseinates and hydroxypropylguar, and (iii) at least one amphiphilic polymer comprising at least one fatty chain and at least one hydrophilic unit.

Solid cosmetic composition and uses thereof

A topical composition separately containing a hydrophilic carrier and a solid which are intended to be mixed immediately before use, the solid being powdered ascorbic acid and the carrier containing an aqueous medium and at least one hydrophilic gelling agent, the carrier being capable of withstanding the introduction of an acidic compound. In a preferred embodiment, the carrier (L) is packaged in a container (,) closed with a cap (,) containing ascorbic acid (P), a perforable and/or detachable separator (,) being provided between the acid and the carrier.

Cosmetic and/or dermatological composition with a hydrophilic carrier and vitamin C which can be mixed immediately before use

The present invention relates to a solid composition for topical application, which is free of fillers, containing, in an aqueous phase, less than 20% of the total weight of the composition of a hydrophillic gelling system having the combination of at least 2% by weight of kappa-carrageenan, relative to the total weight of the composition, and at least one hydrocolloid chosen from xanthan gum and cellulose derivatives which are soluble in hot water.

Solid cosmetic composition free of fillers, containing low amounts of gelling agents

A solid composition free of fillers, comprising an aqueous phase, wherein said aqueous phase comprises a hydrocolloid combination of gellane gum and at least one other hydrocolloid, wherein said gellane gum is present in an amount of at least 2% by weight, relative to the total weight of the composition, and wherein said hydrocolloid combination is present in an amount of less than 20% of the total weight of the composition, formable as tubes, pencils or bars, and useful to care for and/or treat the skin, the scalp, the hair or mucous membranes, to make up the skin and/or keratin fibers such as the eyelashes and the hair, and to style and/or shape keratin fibers, and in particular the hair.

A topical composition separately containing a hydrophilic carrier and a solid which are intended to be mixed immediately before use, the solid being powdered ascorbic acid and the carrier containing an aqueous medium and at least one hydrophilic gelling agent, the carrier being capable of withstanding the introduction of an acidic compound. In a preferred embodiment, the carrier (L) is packaged in a container (1) closed with a cap (3,6) containing ascorbic acid (P), a perforable and/or detachable separator (5) being provided between the acid and the carrier.

Container for ascorbic acid composition

Primary amine salts derived from amino acids containing a urethane

A device for packaging a product comprising: i) a dispensing device such that the product is not brought into contact with the environment, ii) constituent walls which are impermeable to gases and to visible-ultraviolet light, wherein a surface of the walls in contact with the product is non-metallic; and iii) an oxygen-trapping device.

Water-in-oil emulsion containing retinol, its use and its packaging

A composition for topical application is provided containing ascorbic acid and at least one polyol, the latter being present in an effective quantity to obtain a water activity value of the composition which is lower than or equal to 0.85, and at least one structuring agent chosen from polymers and oils, with a view to stabilizing the ascorbic acid. In such a composition ascorbic acid retains its effectiveness over the course of time. The composition obtained can be employed for treating and/or caring for the skin.

Stable composition containing ascorbic acid

The invention relates to the use of a salicylic acid derivative salified with a base, as a stabilizer for an oil-in-water emulsion. This salified derivative has the same properties as its acidic homologue, while at the same time having a less irritating nature. This salified derivative is, in particular, an n-alkanoyl-5-salicylic acid salified with an amphoteric base such as lysine or arginine. The present compositions are more especially intended for the cosmetic and dermatological fields.

Salicylic acid derivative as a stabilizer for an oil-in-water emulsion

The invention relates to a water-in-oil emulsion containing retinol, an oil phase, an aqueous phase and an agent for emulsifying the aqueous phase in the oil phase, the oil phase containing at least one organic solvent for retinol which is liquid at room temperature, and the pH of the aqueous phase being basic, so as to stabilize the retinol for at least two months at 45.degree. C. This emulsion is for cosmetic or dermatological use.

Water-in-oil emulsion containing retinol its use

A solid, transparent or translucent non-alcoholic cosmetic gel contains 65 to 99 weight percent of a polyol, 0.1 to 5 weight percent of a dibenzylidene-ose, 0.1 to 5 weight percent of a hardening agent of the sulfosuccinate type and 0.5 to 40 weight percent of water. The gel is employed in makeup products.
