Cosmetic composition containing an aqueous polymer dispersion and an insoluble silicone, and process and use thereof

Cosmetic or dermatological composition in an aqueous medium comprising a film-forming oligomer and rigid, non-film forming nanometric particles and uses thereof

An aqueous or aqueous/alcoholic cosmetic composition which can be sprayed, comprising an aqueous dispersion of insoluble film-forming polymer particles and at least one insoluble silicone, wherein the polymer particles are present in a concentration greater than 15%, relative to the total weight of the composition, and further wherein the glass transition temperature of the insoluble polymer particles ranges from 15 to 35.degree. C. The invention also relates to a process for the cosmetic treatment of keratinous substances using these compositions and to the use of the silicone for improving the quality of the spraying of the composition.

An aqueous or aqueous/alcoholic cosmetic composition comprising an aqueous dispersion of insoluble particles of a non-ionic film-forming polymer, the polymer particles being at a concentration greater than 15% by weight with respect to the total weight of the composition and the glass transition temperature of the polymer particles of the composition ranging from 15 to 35.degree. C. and a process for the cosmetic treatment of keratinous substances using these compositions.

Cosmetic composition comprising an aqueous non-ionic polymer dispersion

Cosmetic or dermatological compositions comprising in a cosmetically acceptable medium (A) at least one film-forming oligomer having a molecular weight, measured by steric exclusion chromatography, of less than or equal to 50,000, said at least one film-forming oligomer being soluble or dispersible in said cosmetically acceptable aqueous medium; and (B) rigid, non-film-forming particles of average size less than or equal to 1 .mu.m, said rigid, non-film-forming particles being dispersed in said cosmetically acceptable aqueous medium, wherein the compositions may be used, for example, as product bases for maintaining the hairstyle, as products for coating the eyelashes and the eyebrows or as nail make-up and/or care products.

A colorimetric measurement head, for determining the internal color of a non-opaque material, in particular the internal color of the human skin, includes an emitter which emits light, towards the material to be studied, and is separated by an opaque wall from a emitter which receives light which has penetrated into the material and which is reflected thereby. An external surface of the head, which is positioned at the material to be studied, and contacts this surface either by direct application against the surface, or with optical wetting. The light received by the detector comes from the interior of the material, whereas the light possibly reflected by the surface of the material or coming directly from the emitter cannot reach the detector because of the opaque separating wall.

Fluid dispensing container (1) equipped with a dispensing valve (2) carrying an outlet (3) through which the fluid is dispensed during the actuation of a pushbutton carried by the valve; a conditioning chamber (4) of variable volume defined by a mobile wall (5a) subjected to the internal pressure of the container, communicates, on the one hand, with the dispensing valve (2) and, on the other hand, with the inside (18) of the container through a retarder means made in the form of a passage with high head loss. At the end of emptying of the conditioning chamber (4), the communication between the dispensing valve (2) and the inside (18) of the container is interrupted.

Fluid dispensing container for dispensing a predetermined quantity of a

Device for mixing at least two products (11, 21) each contained in a container (10, 20), one of the containers (10), or first container, having a volume suitable to receive the product (21) contained in the other container (20), or second container, in order to obtain the mixture (41) of the two products (11, 21), the first container (10) comprising, in its upper part, a push-button (15) equipped with a nozzle (16) and the actuation of which allows the mixture (41) to leave the first container (10) via the nozzle (16); the two containers (10, 20) are carried by a common casing (30) into which they are fitted so as to slide between two positions, a position called far-apart position for which the two containers (10, 20) are not in communication, and a position called close-together position for which the two containers (10, 20) are in communication, the casing (30) preventing, in the far-apart position, any action on the push-button (15) of the first container (10) and allowing action on the said push-button (15) in the close-together position, communication means (17, 18, 22) which can be closed off being provided between the two containers (10, 20).

The device for the compression of a gas comprises a motor (1), a piston (2) adapted to be displaced linearly in a pump body, transmission means (T) between the motor (1) and the piston (2) adapted to convert the rotary motion generated by the motor (1) into a reciprocating translatory motion by the piston (2). Speed varying means comprising a cam (12) are provided to impart a different speed to the piston (2) of the compressor according to the resistance opposing the motor (1) during one complete admission/compression cycle, so that the resisting torque is substantially constant and so that the motor (1) operates at its maximum torque and therefore at maximum efficiency. The section of the cam (12) is determined so as to ensure substantially isothermal compression of the gas.
