Abstract: A powder cosmetic product in the form of a flat wafer or plate or extruded rod for lipsticks includes a cosmetic body with a visible surface provided with a plurality of protruding stripes with triangular section. Each stripe has a vertex, a first inclined side decorated with a portion of a first image, and a second inclined side decorated with a portion of a second image. By observing the cosmetic body from an observation point (A) angled so that only the first inclined side of each stripe can be seen, only the first image is visible, while by observing the same cosmetic body from an observation point (B) angled so that only the second inclined side of each stripe can be seen, only the second image is visible.

Said polyurethane is able to form a film on skin, and is preferably provided with gloss. (FIG.

Abstract: A cosmetic ingredient for cosmetic products has a polymer structure which includes an emollient or film-forming cosmetic polymer which is transparent to light. An organic chromophore molecule is inserted and chemically linked into the polymer, which can be a fixed color molecule or a photochromic molecule capable of rapidly switching from one color to another. The colored or photochromic molecule is inserted and chemically linked by transesterification into a cosmetic oil provided with functionalities which are suitable for the chemical anchoring of the molecule and chemically linked to said oil. The cosmetic oil may be a silicone macrodiol functionalized with a photochromic derivative designed so as to ensure the transition between a colorless state and a colored state following irradiation with ultraviolet light.

Abstract: Native or physically or chemically modified starches, consisting of insoluble native particles with a smooth surface, free of edges, harshness, and roughness of any kind, are used as ingredients for cosmetic compositions. The particles can be of a regular spheroidal shape with diameter between 0.1 and 60 microns or of a lenticular/lamellar shape with diameter between 5 and 60 microns and thickness between 0.5 and 15 microns. Using such starches allows obtaining cosmetic compositions with high aesthetic features.

Abstract: A process for coloring a solid compact powder cosmetic cake includes dripping ink droplets of various colors and various sizes onto an upper surface of the solid compact powder cosmetic cake, and impregnating the ink droplets into the solid compact powder cosmetic cake.

Abstract: A cosmetic composition comprising Janus particles, an aqueous phase and an organic phase uses Janus particles produced with a method which includes the preparation of hollow particles (1) having two non-continuous surfaces of a material with surface energy ?, of which the external one (2) is accessible and the internal one (3) is inaccessible. The surface energy of the external surface (2) is thereby modified originating particles (11) with internal surface energy ? and external surface energy ?. The modified particles (11) are then ground until particles are obtained constituted by small fragments (21) shaped as spherical caps with external surface (12) having modified energy and internal surface (13) having non-modified internal energy.

Abstract: A lipstick (13, 17, 19, 21, 23) with external lateral surface having a tridimensional design is obtained by a process comprising laser-working the external lateral surface of a head part (2), previously mirror-polished, of a rough tap (1). The process may include the final pearling of the lipstick (13, 17, 19, 21, 23) by means of a cyclone system (14) to obtain a pearled lipstick (16, 18, 20, 22, 24).

Abstract: A fluid cosmetic composition with unusual rheologic characteristics has a formulation comprising 0.1 to 50% by weight of at least one fluid branched polymer obtained by simultaneous reaction from components A. B and C, where A is a linear polymer with a molecular weight Mw between 5000 and 50000 Da, provided with reactive functional groups X in a chain at a concentration between 0.1 and 50 mmol/g of polymer. B is a linear polymer with a molecular weight Mw between 10000 and 100000 Da, having terminal reactive functional groups of type Y capable of reacting with the functional group X in an addition or condensation reaction, and C is a molecule or linear oligomer (or a mixture thereof) with a molecular weight between 50 and 1000 Da, having a reactive functional group Y per molecule, capable of reacting with the functional group X in an addition or condensation reaction. The molar ratio of the functional groups of B and A is between 0.01 and 0.

Abstract: A powder cosmetic composition with a chromophore-based coating is described. The composition comprises from 0.1% to 50% by weight of at least one chromophore selected among polymeric chromophores chemically linked to polyols with reactive functional groups and from 99.9% to 50% by weight of a cosmetic powder or mixture of cosmetic powders having superficial reactive groups.

Abstract: An innovative process for coloring solid compact powder cosmetic products includes dripping ink droplets (5) of various colors and sizes onto an upper surface (3) of the cosmetic cake (1), and impregnating them into the cake itself.
