A method is provided for preparing a hair dye color mixture. The method includes: accessing a control system having at least a processor, a memory, and user input controls, the memory configured to store ingredients of a hair dye color mixture, receiving user input from the user input controls to change one or more ingredients of the hair dye color mixture to a new product brand; matching the color of the hair dye color mixture using one or more ingredients of the new product brand, in response to the user input; and displaying the ingredients of the hair dye color mixture in the new product brand on a display.

The invention concerns a device 51 for mixing at least two components, characterised by the fact that the mixing device 51 comprises two containers 52 and 53 each provided with: a. at least one opening 110 connected by a conduit 55 and provided with a device allowing the available volume of the containers 52 and 53 to be varied alternately, pistons 50 that are able to be moved in opposing directions, so as to transfer the content from one of the containers 52 or 53 into the other container 52 or 53 through the openings 110 and the conduit 55; and b. at least one inlet opening X allowing the at least two components to enter; said mixing device not comprising an additional outlet opening, one of the inlet openings X allowing both at least one component to enter, and the mixture of the at least two components obtained to leave. The invention also concerns a method for mixing cosmetic components using this mixing device and a device for manufacturing and dispensing a customised cosmetic composition comprising said mixing device.

The invention belongs to the field of personalized cosmetics which, in terms of their composition, are determined by the end user (personalized), and it relates to a method for producing said cosmetics, and to dosing containers for the production thereof, and also to the use of cosmetic mixtures in the dosing containers and the use of the dosing containers for carrying out the method.

A method for preparing stable liquid emulsion forms of plant extract is provided. A plant extract having a bitter flavor is mixed with diluent oil as an oil mixture and heat is applied to the oil mixture. An emulsifying agent is dispersed in water as an emulsifying solution. The oil mixture is mixed with the emulsifying solution. The mixed oil mixture and emulsifying solution is homogenized as a liquid form of the plant extract. Gluconic acid is added to the liquid form of the plant extract. The bitter flavor of the plant extract is disguised by adding a bitter blocker to the liquid form of the plant extract.

The presently disclosed subject matter relates to a system and method for customizing a cosmetic product. The system includes: an interface device, in electronic communication with a single batch cosmetic device. A container configured, to be imported into the single batch cosmetic device containing a base. The single batch cosmetic device configured to formulate a customized cosmetic product by mixing a cosmetic additive with the base inside the imported container using at least one mixing element. The container exported from the single batch cosmetic device containing the customized cosmetic.

Apparatus and methods for variable-control fragrance dispensing. The disclosed device brings customization to the fragrance industry. Interchanging sub-containers and selecting the amounts of each sub-container allows a user to customize their scents. A mixing chamber contained to receive and mix a variable amount of each liquid from a plurality of sub-containers is described. The mixed liquid is sprayable out a spray head of the device. Selector knobs may be used to control valves which control the variable amount of each liquid dispensed.

A mixing assembly, device, system and method for operating are provided which includes a powder assembly holding a first container containing a powder, the powder assembly having a powder dispensing means for dispensing a predetermined quantity of the powder, a liquid assembly holding a second container containing a liquid, the liquid assembly having a liquid dispensing means for dispensing a predetermined amount of the liquid, and a mixing bowl for receiving the predetermined quantity of the powder and the predetermined amount of the liquid.

A capsule for mixing multiple substances, comprising: a main chamber having a main chamber bottom and a main chamber top opening; at least two repository tubular chambers, each: adapted to contain substance, mechanically connected to the main chamber and having a repository tubular chamber top opening; at least two passages, each fluidly connecting one of the at least two repository tubular chambers to the main chamber; a main piston fitted in the main chamber; and a mixer rod having a mixer element disposed at a distal end and a torque adapter disposed at a proximal end for transferring a torque to the mixer element, the mixer rod is fitted to pass along the main piston such that the mixer element is mounted in the main chamber between the main chamber bottom and a distal end of the main piston when the main piston is in the outward position.

A dispensing system includes a container containing a flowable base formulation to be dispensed, an additive mixing device, and an actuable pump engine which draws the flowable base formulation from the container and pumps it through the mixing device. The additive mixing device includes a body with an internal cavity, an additive ingredient within the cavity, and a flow path/mixing chamber between an input and an output. With each pump of the device the additive ingredient is introduced into, and mixed with, a flow of the base formulation traveling through the mixing device. Multiple additive mixing devices may be interchangeable for different formulations, and the mixing devices may be refillable.

One aspect of the present disclosure is an apparatus for manufacturing cosmetic containing: a main body providing a space for manufacturing cosmetic; a mixing vessel that can store cosmetic materials and a parts supply unit providing components including a plurality of cosmetic containers; a cosmetic material supply unit that can store cosmetic materials and then discharge cosmetic materials to the mixing vessel; a transfer unit that can transfer the mixing vessel and the components including the cosmetic container; and a control unit that can control the movement of the transfer unit in order to simultaneously assemble a plurality of cosmetic containers from the mixing vessel and the components.
