A device for producing a dispersion including elements including a first phase, which are dispersed in a continuous phase immiscible with the first phase is described herein. The device including at least one production nozzle including a first duct intended to convey a first fluid that forms the first phase, a second duct, coaxially surrounding part of the first duct, able to convey a second fluid that forms the continuous phase, and an outlet. The nozzle is able to form, at the outlet, a fluid jet including the first fluid and the second fluid surrounding the first fluid. The production device additionally includes a fragmentation device for mechanically breaking up the fluid jet, positioned in the vicinity of the outlet of the nozzle, the fragmentation device including a mobile part intended to break up the fluid jet mechanically into a plurality of elements.

Devices and methods for dispersing a first phase in a substantially immiscible continuous phase

The present invention relates to a composition, in particular cosmetic, in the form of an oil-in-water emulsion, comprising a continuous aqueous phase and a dispersed oil phase in the form of drops (G1) and drops (G2), wherein the size of the drops (G1) is less than 500 μm and the size of the drops (G2) is greater than 500 μm.

Oil-in-water emulsions of which the oil phase is in the form of a mixture of drops of different sizes

A method of manufacturing a series of capsules (A) comprising a core (), and a gelled envelope () completely encapsulating the core and comprising at least two external phases (A,B), wherein the gelled envelope has a external surface comprising at least two distinct portions (A,B) formed respectively by the two external phases, and comprising the following steps: Series of capsules, cosmetic composition containing the capsules and cosmetic treatment using the composition.

Series of capsules and method of manufacture, cosmetic composition and cosmetic treatment

The present invention relates to a plant () for producing a composition (), in particular a cosmetic composition, comprising drops () of at least one first fluid dispersed in a second fluid substantially immiscible with the first fluid, each drop () comprising a core formed of the first fluid, and optionally a shell suitable for retaining the core, the plant () comprising:

Plant for producing a composition comprising drops and associated production process

This device comprises: a container defining an inner volume intended to contain the product closed off by a movable bottom and opening out through a dispensing neck; a dispensing member; a purge ring comprising a base that delimits a central orifice defining a central axis of the ring, the base having an outer contour and a side surface converging from the outer contour toward a second end of the central orifice. The device is characterized in that the purge ring comprises at least one radial opening arranged radially relative to the central axis and allowing the passage of the product from the container toward the central orifice.

Device for packaging and dispensing a product in an airless manner, notably in several phases, associated purge ring and method

Each capsule comprises a liquid core () and a gelled shell () comprising a gelled polyelectrolyte completely encapsulating the liquid core () at the periphery thereof. The gelled shell () is suitable for retaining the liquid core () when the capsule () is immersed in a gas. The liquid core () comprises an intermediate drop () of an intermediate phase, the intermediate phase being placed in contact with the gelled shell (), and at least one internal drop () of an internal phase placed in the intermediate drop (). The ratio of the volume of the core () to the volume of the gelled shell () is greater than 2, advantageously is greater than 50.

Series of capsules comprising at least one drop of internal phase in a drop of intermediate phase and manufacturing method thereof

This device comprises a hollow body, the hollow body defining: an internal conduit for distributing the first fluid, the internal conduit defining an inner volume; an external conduit or distributing the second fluid, the internal conduit and the external conduit extending coaxially along a longitudinal axis (AA'). It at least comprises one metal tube extending along the longitudinal axis (AA&#x2032;) and being positioned in the inner volume of the internal conduit and/or in the downstream extension of the internal conduit and/or of the external conduit.

Device for producing dispersed elements, associated assembly and production method

This method comprises the following steps: flowing drops of a first phase, through a circulation duct, into a second phase that is substantially immiscible with the first phase, each drop comprising a core formed from the first phase and a shell formed from a layer of coacervate inserted between the first phase and the second phase; recovering a dispersion containing drops and the second phase in a container; injecting a solution for increasing the viscosity of the second phase in the circulation duct or at the outlet of the circulation duct, upstream from the container.

Method for forming a dispersion comprising drops, and associated apparatus

The device () for dispensing a fluid composition includes: a container () containing a heterogeneous mixture ();
