A process for preparing a stable and anhydrous solid dispersion, containing from 20 to 95 weight percent of a fatty body, constituted of 10 to 50 weight percent of at least one wax having a melting point greater than 55&deg; C., and from 4 to 50 weight percent of a polyhydric alcohol, involves heating the fatty body and the polyhydric alcohol to a temperature between 65&deg; and 95&deg; C. and mixing the heated components in a turbine rotating at a speed greater than 1500 rpm. The resulting dispersion is employed in the production of cosmetics in stick form.

Process for the preparation of a solid dispersion of at least one polyhydric alcohol in a fatty body and the resulting dispersion for cosmetic and pharmaceutical use

Composition for the treatment of the nails, containing a sulphur-bearing aminoacid or derivative thereof. This composition is prepared by introducing a sulphur-bearing aminoacid together with sodium tetraborate into an aqueous or water-alcohol medium. The combination of these two ingredients gives a composition with which embrittled or damaged nails can be treated and at the same time cuticles can be eliminated.

A process for preparing a stable and anhydrous solid dispersion, containing from 20 to 95 weight percent of a fatty body, constituted of 10 to 50 weight percent of at least one wax having a melting point greater than 55.degree. C., and from 4 to 50 weight percent of a polyhydric alcohol, involves heating the fatty body and the polyhydric alcohol to a temperature between 65.degree. and 95.degree. C. and mixing the heated components in a turbine rotating at a speed greater than 1500 rpm. The resulting dispersion is employed in the production of cosmetics in stick form.

Preparation of an effervescent aqueous solution which has an emollient action on the cuticles of the nails, by dissolving the following anhydrous solid compounds substantially simultaneously in water: urea, pyrrolidonecarboxylic acid and an alkali metal and/or ammonium bicarbonate, and additional ingredients, the different compounds being introduced in the form of a mixture or of several separate mixtures prepared in advance. These mixtures are in pulverulent or tablet form. Composition for the preparation of the effervescent aqueous solution. Cosmetic treatment of the cuticle of the nails using the effervescent aqueous solution.

The dispenser comprises a shell enclosing a movable reservoir for the product. A dispensing valve is formed in a zone between the shell and the reservoir. Control member allow a relative displacement to be effected between the shell and the reservoir to open the dispensing valve and to allow the product to flow out. Openable passage are capable of connecting the inside of the reservoir to the atmosphere when the control member are actuated to open the dispensing valve.

Liquid product dispenser, in particular for a cosmetic product such as

A rod or stick for pharmaceutical or cosmetic use in topical application to the skin of an easily oxidizable active substance comprises an internal fatty phase or core phase containing in an anhydrous medium the oxidizable active substance. The said core phase is protected from oxidation by an external fatty phase or sheath phase containing at least one surface active agent. The said sheath phase entirely envelopes the circumferential surface and at least one end section of said core phase.

An emulsifying system for use in the production of cosmetic or pharmaceutical compositions in the form of an emulsoid or gel comprises (i) at least one fatty acid having from 8 to 22 carbon atoms or a protein condensate of a fatty acid having from 8 to 40 carbon atoms and a polypeptide of animal origin, (ii) a polyoxyethylenated sterol and (iii) a phosphatide.

Emulsifying system based on a fatty acid or a protein condensate, a

Copper lanolate, a novel product, can be produced by initially preparing an isotropic solution of a sodium or potassium salt of lanolic acid and thereafter precipitating copper lanolate therefrom by the addition thereto of a solution of a copper salt. The resulting copper lanolate is employed in anti-acne compositions for topical application to the skin.

Emulsions of the water-in-oil type having a water phase, an oil phase and an emulsifying agent consisting of a metal or alkaline-earth metal lanolinyl lactylate. The emulsions may also be in the form of cosmetic compositions, including other cosmetic additives, or may be used as pharmaceutical excipients.

Emulsions of the water-in-oil type useable as cosmetic supports or

Stable emulsions are provided which can be either in the form of 'water-in-oil' or 'oil-in-water' emulsions and are obtained using a mixture of lanolin acid and at least one natural basic .alpha.-amino acid, the proportions in the mixture determining the form of the emulsion.

A novel automatic test measuring apparatus of the pendulum variety for readily and easily determining film and the like hardness is adapted to automate all the operations necessarily preceding the commencement of a measurement stage using, in connection therewith, a recording unit or printer to supply the operator with the numerical results of all the measurements without personal manipulation(s). In making a measurement, the necessary time count for passing from amplitude .alpha. to amplitude .beta. is effected by means of a photo-electric cell. This records the passage of a pendulum arm having a predetermined period during the time that the oscillation amplitude is higher than .beta.. The involved count gives the measured time necessary for the measurement. The automatic apparatus advantageously reduces error relating to each measurement and increases the number of measurements to be effected on one and the same test film to yield a vastly more reliable mean statistical value. Provision may be made to simultaneously test several films, either by simultaneous of successive mountings of a plurality of films whose hardness is being measured.
