A fluid formulation assembly for a formulation dispenser includes a fluid container configured to store a volume of fluid cosmetic formulation, a drive assembly operatively connectable to the fluid container and configured to dispense the fluid cosmetic formulation, and a carriage that receives the fluid container and is configured to interface with the drive assembly. The fluid container is removably attachable with the carriage without tools and at least one of the drive assembly or the carriage is removably attachable with the cosmetic formulation dispenser.

Fluid formulation assembly for custom formulation systems

The invention relates to a method for determining the color of a cosmetic product on a skin model, the method including steps to: &#x2014;for a plurality of wavelengths, supply experimental points giving diffusion and/or absorption values for several mixes of a given concentration of one pigment in another pigment, each mix corresponding to different given concentrations, and &#x2014;use a physicochemical model capable of predicting interactions between pigments passing through experimental points to obtain the curve giving the diffusion and/or absorption for each wavelength as a function of the given concentration of pigment in the mix of pigments considered.

The invention relates to a method for determining the color of a cosmetic product adapted to the skin of a wearer of the cosmetic product, the method including the following steps: &#x2014;supply data related to the color of the wearer's skin, &#x2014;determine the color of the cosmetic product by using a correspondence function applied to data about the color appearance of the wearer's skin, the correspondence function associating a cosmetic product color with a wearer's skin color appearance, the correspondence function having at least three reference associations, a reference association associating a predetermined cosmetic product color with a predetermined wearer skin color within a tolerance, the tolerance being equal to a distance of 2 in the L*a*b* color space.

The apparatus for assistance in makeup includes a measurement unit for measuring local phenomena of light interaction with a zone to be made up and/or treated; a database relating to the BRDF of various cosmetic and/or care products; a selector unit enabling a product to be selected; a calculation unit for calculating the resulting BRDF to the zone virtually made up or treated with the product, on the basis of measurement previously taken and on the basis of information taken from the database and relating to the BRDF of the selected makeup product; and a display unit for displaying the zone virtually made up or treated in this way as a result of the previously calculated resulting BRFD.

Apparatus for assisting makeup and an assembly constituted by such apparatus and apparatus for delivering makeup having a predetermined BRDF as selected by the apparatus for assisting makeup

A portable dispenser has at least two containers organized to enable the substances they contain to be dispensed in proportions selected by the user, and a mixing chamber into which the substances contained in the containers are dispensed and in which they can be mixed together. The substances contained in the containers have different colors, the dispenser includes at least one stirrer that is movable in said mixing chamber, and the mixing chamber is organized to enable the user to observe the color of the resulting mixture prior to extracting it.

Portable dispenser for packaging and dispensing colored cosmetics

The invention relates to apparatus for measuring color, the apparatus comprising: an acquisition system including a video camera and processing means organized to respond to the signals delivered by the camera to determine the tristimulus values of the color of the object in a reference colorimetric system by using a transfer matrix to transform the colorimetric system associated with said acquisition system into the reference colorimetric system, and to determine a correction function &Ggr; to correct the non-linearities of said acquisition system.
