Cosmetic blending devices for producing a cosmetic liquid from a solid-shell cosmetic ingredient capsule. The cosmetic blending devices include a lid, a base, a blending element configured to blend the capsule, and a drive mechanism configured to actuate the blending element. The cosmetic blending device may include a thermal element configured to change a temperature of the capsule. The thermal element may melt the capsule. The solid-shell cosmetic ingredient capsule comprises a shell defining an enclosed inner volume, and cosmetic material included in the enclosed inner volume. Methods of using the cosmetic blending devices comprise placing the solid-shell cosmetic ingredient capsule into the cosmetic blending device and blending the capsule to produce the cosmetic liquid. Methods of forming the solid-shell cosmetic ingredient capsule comprise forming a portion of the shell, adding the cosmetic material to the portion of the shell, and forming the remaining portion of the shell.

A reactor for coating particles includes a stationary vacuum chamber having a lower portion that forms a half-cylinder and an upper portion to hold a bed of particles to be coated, a vacuum port in the upper portion of the chamber, a paddle assembly, a motor to rotate a drive shaft of the paddle assembly, a chemical delivery system to deliver a first fluid, and a first gas injection assembly to receive the first fluid from the chemical delivery system and having apertures configured to inject a first reactant or precursor gas into the lower portion of the chamber and such that the first reactant or precursor gas flows substantially tangent to a curved inner surface of the half-cylinder.

A stirring wand is configured for selective engagement with a mixing device. The stirring wand comprises a substantially vertical portion having an upper end and a lower end, a first tapered surface that includes a first pitch angle proximate the upper end of the substantially vertical portion and a second pitch angle proximate the lower end of the substantially vertical portion, a substantially horizontal portion having a base and a distal tip, and a second tapered surface extending from the base to the distal tip. The second tapered surface includes a third pitch angle proximate the base and a fourth pitch angle proximate the tip.

A method of coating particles includes dispensing particles into a vacuum chamber to form a particle bed in at least a lower portion of the chamber that forms a half-cylinder, evacuating the chamber through a vacuum port in an upper portion of the chamber, rotating a paddle assembly such that a plurality of paddles orbit a drive shaft to stir the particles in the particle bed, injecting a reactant or precursor gas through a plurality of channels into the lower portion of the chamber as the paddle assembly rotates to coat the particles, and injecting the reactant or precursor gas or a purge gas through the plurality of channels at a sufficiently high velocity such that the reactant or precursor a purge gas de-agglomerates particles in the particle bed.
