A method may prepare a tinted cosmetic composition, in particular a make-up composition, which is particularly versatile. Such a method may make it possible to prepare tinted cosmetic compositions that can be suitable for many types of skin tone, e.g., including preparing a continuous hydrophilic phase comprising (i) a hydrophilic compound A in a range of from 90 to 99.6 wt. % of a hydrophilic phase of the oil-in-water emulsion, and (ii) a polymer P, in a range of from 0.4 to 10 wt. % of the hydrophilic phase, the polymer P comprising, in polymerized form, an anionic monomer (a1) and a C.sub.1-C.sub.8 ester (a2); adding, under stirring, a lipophilic phase comprising a lipophilic compound B, to form a dispersion of lipophilic phase particles in the continuous hydrophilic phase; then adding, under stirring, of a pigment C. The coloration, retention, and stability properties of such compositions are particularly improved.

The present invention provides a method for producing natural polymer microspheres, the method including: adding a solution containing a natural polymer (e.g., an aqueous fibroin solution) to an organic solvent, the organic solvent having a surfactant dissolved therein, and homogenizing the resulting mixed solution to generate a natural polymer colloidal suspension; and adding the natural polymer colloidal suspension to an alcohol having 3 or more carbon atoms to form natural polymer microspheres.

The present disclosure provides biophotonic topical compositions and methods useful in phototherapy. In particular, the biophotonic topical compositions of the present disclosure are substantially resistant to leaching such that very low amounts of chromophore(s) present in the biophotonic composition leach out of the composition. The biophotonic compositions and the methods of the present disclosure are useful for promoting wound healing and skin rejuvenation, as well as treating acne and various skin disorders.

This invention provides a groundbreaking approach to PLNPs and their preparation. In particular, the synthetic methodology disclosed herein fundamentally differs from the traditional solid-state annealing reactions that require extreme and harsh reaction conditions. In one unique aspect of the invention, a simple, one-step mesoporous template method utilizing mesoporous silica nanoparticles (MSNs) is disclosed that affords in vivo rechargeable NIR-emitting mesoporous PLNPs with uniform size and morphology. In another unique aspect of the invention, the novel synthetic approach is based on aqueous-phase chemical reactions conducted in mild conditions, resulting in uniform and homogeneous PLNPs with desired size control (e.g., sub-10 nm).

The method comprises the following steps: (a) forming a powder layer (19) comprising at least one cosmetic powder; (b) supplying a photoactivatable material on at least a first region of the layer (19); (c) illuminating at least the first region of the layer (19) to activate the photoactivatable material; (d) forming an additional powder layer (19) comprising at least one cosmetic powder; (e) supplying a photoactivatable material on at least a second region of the additional layer (19); (f) illuminating at least the second region of the additional layer (19) to activate the photoactivatable material; (g) repeating steps (d) to (f) until the three-dimensional object is formed.
The cosmetic composition comprised in the three-dimensional object or forming the three-dimensional object can be restored after the three-dimensional object is formed.

A light emitting composition including first color emitters and second color emitters. The first color emitters are configured to emit, upon exposure to an energy source, visible light at a target color in response to absorption of energy across a first band of wavelengths. The second color emitters are configured to emit, upon exposure to the energy source, visible light at the target color in response to absorption of energy across a second band of wavelengths. The light intensity observable at the target color is enhanced relative to reflected white light without emission from the first and second color emitters. The light emitting composition can be a part of a paint, an ink, a fabric, a thread, a road sign, a highway marking, an automobile, a boat, a plane, a reflector, a building product, a concrete product, an epoxy product, a jewelry product, colored contact lens, a candle product, a rubber product, a plastic product, or other colored surface.
