Disclosed is a fluid dispenser, comprising: a housing having an internal reservoir for containing a fluid, such as an oral care fluid, and an applicator connected to the housing. The applicator comprises a base having an exterior surface, the base comprising a valve having a movable portion defining an outlet of the valve and forming part of the exterior surface, and one or more projections extending from the exterior surface adjacent the valve outlet. The valve is for selectively blocking a passageway that is in fluid communication with the internal reservoir.

A method for reducing skin staining during the coloring of hair includes the following steps in the indicated sequence: A1) applying a coloring agent (F) to the hair, A2) allowing the coloring agent (F) to act for a time period from 30 seconds to 45 minutes, B1) applying an undiluted cleaning agent (R) to skin areas that can come into contact with the coloring agent (F) when the latter is washed out, C1) jointly washing out the coloring agent (F) and cleaning agent (R), wherein the coloring agent (F) includes at least one oxidation dye precursor and/or at least one direct dye and the cleaning agent (R) includes at least one anionic surfactant.

A multicomponent packaging unit includes the coloring agent (F) and the cleaning agent (R).

The present invention is directed towards a cosmetic assembly, of use for the treatment of keratin fibres, comprising a fluid cosmetic composition containing at least particles in the dispersed state in a liquid medium, said composition being solidifiable via the aggregation of said particles; and a device (1) comprising a mould (2), the mould (2) comprising at least one cavity (5), into which or each of which at least one of said fibres can be at least partially introduced, for the purposes of moulding said composition onto at least one part of said fibre(s) present in the cavity or cavities (5). The present invention is also directed towards a process for cosmetic treatment of one or more keratin fibres.

An apparatus for applying a two-component liquid composition to a surface has a housing having an open end, and a roller ball disposed and rotatably retained in the housing and projecting through the open end. There are two containers disposed at least partially in the housing. Each container has a dispensing nozzle arranged adjacent the roller ball. The nozzles have an open end such that a liquid or pasty substance disposed in each of the containers flows from the containers through the nozzle directly to the roller ball upon application of pressure to the substances in the containers. Rolling roller ball across a surface mixes the two substances on the roller ball with each other. This occurs by virtue of the movement of the roller ball around the surface, which causes the substances to flow around the ball and mix with each other during rolling.

A dispenser includes a first pouch configured to store a first component of a two component material, a second pouch, separate from the first pouch, and configured to store a second component of the two-component material, an outlet part having an outlet via which the first and second components stored in the first and second pouches are capable of being dispensed after the first and second components have been mixed in the outlet part, and a neck connected to the first and second pouches, a longitudinal axis of the dispenser extending in parallel to the outlet, and the first and second pouches being compressible towards one another in the direction of the longitudinal axis, the outlet part axially moveable relative to the first and second pouches in a direction towards the neck along the longitudinal axis.

An applicator for applying a product to hair, especially a hair colouring product, including: at least one first row of teeth extending longitudinally over a distance l.sub.1, from a first application face of the applicator; and a plurality of second rows of teeth, extending longitudinally over a distance l.sub.1, from a second application face of the applicator, which is arranged opposite the first application face, the ratio l.sub.1/l.sub.2 being lower than or equal to 0.75.

An apparatus for dispensing a fluid from a source of fluid comprises a roller and a tray member. The tray member comprises a pair of spaced walls having a contiguous tapered inner surface for defining an arcuate recess in an outer surface of the tray member, the outer surface tapering to an outer edge of each wall. Roller mounting means includes a pair of resilient spaced arms, each one of the arms spanning between and interconnecting the ends of the spaced wall. The tray member defines a pair ports spaced along a central longitudinal axis of the tray member for providing fluid communication between the source of fluid and the tray member. The roller is rotatably mounted to the spaced arms for receiving fluid from the tray member and applying the fluid onto a surface.

The subject of the present invention is a compound of formula (I) below, the addition salts thereof, the dimer thereof and also the organic or inorganic acid salts thereof, the optical isomers thereof, the geometric isomers thereof, and the solvates thereof such as hydrates: (I) These compounds are sensitive to pH and of use for the treatment of keratin fibers, such as human keratin fibers and in particular the hair. ##STR00001##

A plug for releasably sealing a connection channel connecting an upper chamber comprising a first component with a lower chamber comprising a second component of a two-chamber container, comprising a plug body for being inserted into the connection channel with a sealing force, a guiding member for guiding the plug in axial direction inside the upper chamber, wherein the guiding member comprises a larger extension in radial direction than the plug body and the guiding member is axially spaced to the plug body by an unsealing distance, and a head part for pushing out a folded nozzle sealing the upper chamber, wherein the head part protrudes from the guiding member away from the plug body.
