The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

The present invention relates to a process for treating keratin fibers, comprising the application to the keratin fibers of a composition (C) comprising at least one (poly)carbodiimide compound, at least one aqueous dispersion of particles of polymer(s) chosen from polyurethanes, acrylic polymers, and mixtures thereof, optionally at least one silicone, and at least one coloring agent chosen from pigments, direct dyes, and mixtures thereof.

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.

An aqueous suncare formulation is provided, including: a cosmetically acceptable aqueous carrier; a suncare active; and a sulfated crystalline cellulose SPF booster; wherein the sulfated crystalline cellulose SPF booster both boosts the SPF of the aqueous suncare formulation and thickens the aqueous suncare formulation.

Devices, systems, materials, and methods for contouring a volume of hair are described. A hair contouring device can include a contouring source. The contouring source can be configured to generate contouring electromagnetic radiation within a first energy range to induce a conformation change of a hydrogel formulation. The hair contouring device can include a fixing source. The fixing source can be configured to generate curing electromagnetic radiation within a second energy range to induce a photo-curing transition of the hydrogel formulation. The hair contouring device can include an input component. The hair contouring device can also include control circuitry, electrically coupled with the contouring source, the fixing source, and the input component. The control circuitry can be configured to receive an input from the input component and to control the contouring source or the fixing source in accordance with the input.

The invention describes a cosmetic article, in particular for make-up, in stick form comprising a transparent external product and a liquid internal product in which solid decorative elements are dispersed. The cosmetic article features an attractive, original appearance, which can be appreciated from both an aesthetic and a functional point of view upon application thereof to skin.

A method and a kit-of-parts are provided for dyeing keratinous material. The method includes applying a first agent to the keratinous material and applying an second agent to the keratinous material. The first agent includes at least one organic silicon compound. The second agent comprises at least one colorant compound and at least one film-forming polymer. The colorant compound includes at least one effect pigment including a substrate platelet including synthetic mica. The colorant compound further includes a coating including at least a first metal oxide (hydrate) layer.

The instant disclosure generally relates to a multicomponent composition for coloring mammalian or synthetic keratin fibers, the multicomponent composition comprising first, second, third and fourth components. The first component includes an organic polymer, the second component includes an in situ linking material, the third component includes a base compound and the fourth component includes a catalyst or other substance. One or more of the components includes pigment microparticles. The multicomponent composition in situ links upon application, forms a solid coating on treated material such as hair and has a substantially long color remanence following development. Methods of using such compositions are also described herein.

Composition comprising at least one acrylate-functionalized polymer and at least one silicone chosen from silicones functionalized with at least one mercapto or thiol group The present invention relates to a composition intended for the cosmetic treatment of keratin fibres, in particular of human keratin fibres such as the hair, comprising one or more acrylate-functionalized polymers and one or more silicones chosen from silicones functionalized with one or more mercapto groups, amino silicones, and mixtures thereof.
