The present disclosure relates to the field of hair coloring compositions. Described herein is an oxidative hair coloring composition including microcapsules made of a perfumed-oil based core and a polymeric shell. Also described herein are a method for coloring hair and a hair coloring kit.

Provided is a core-shell structure having an excellent immediate effect in transdermal absorption of an active ingredient.

A core-shell structure comprising a core portion containing an active ingredient, and a shell portion containing a surfactant having an HLB value of 4 to 14, the core portion being solid, and the surfactant containing a saturated hydrocarbon group having 7 to 15 carbon atoms or an unsaturated hydrocarbon group having 7 to 17 carbon atoms.

According to the present invention, provided is a core-shell structured chromic microcapsule having a size of 50-1,500 m, comprising: a core comprising a colorant core (A) and an optional inner color layer (B); and a shell comprising a pressure sensitive destructible wall layer (C) encompassing the core, an optional outer color layer (D) and an optional outermost protective layer (E), wherein the colorant core allows a high content of a colorant to be contained, and the pressure sensitive destructible wall layer comprises carbon dioxide particles and a binder comprising one or more wall-forming materials and one or more lipid-base materials. The chromic microcapsule according to the present invention has high colorant content, has excellent storage durability, maintenance durability and color-hiding property of the inner color layers, is easily destroyed by pushing, rubbing, polishing or scrubbing with the hands or a tool (cotton fabric, sponge or paper) so as to express the color of the inner color layers, and can maintain stability for a long time even if being added into a carrier.

An oil-in-water type cosmetic composition, including the following components (A), (B), (C1), and (E): (A) titanium oxide coated with a surface treatment agent including aluminum, (B) a water-soluble polymer having a constitutional unit of sulfonic acid, (C1) an oily compound whose molecule includes one or more hydroxy groups and two or more fatty acid groups having 8 or more carbon atoms or two or more hydrocarbon chains having 8 or more carbon atoms in an amount of 0.6 mass % or more, and (E) a dextrin fatty acid ester.

The purpose of the present invention is to provide an oil-in-water emulsion composition exhibiting high UV-protective capabilities with which it is possible to uniformly and stably disperse a hydrophobized metal oxide into an inner phase (oil phase) without detracting from the inherent fresh sensation on use of an oil-in-water emulsion composition even when a high amount of the hydrophobized metal oxide is compounded therewith. In summary, the present invention is an oil-in-water emulsion composition characterized by including (A) 0.1-5 mass % of polyether-modified silicone having an HLB (Si) of 5-14, (B) one or more hydrophilic thickeners, (C) a metal oxide hydrophobized by an agent other than metal soap, and (D) nonvolatile oil other than silicone oil, the (C) hydrophobized metal oxide being present in the inner phase.

The present invention provides a composition containing component (A): a compound represented by the formula (1) ##STR00001##
wherein each symbol is as described in the DESCRIPTION, or a salt thereof, and component (B): at least one kind of inorganic powder. The composition can be produced conveniently, shows good dispersibility, and is superior in the sense of use such as moist feeling, feeling of close adhesion and affinity, and a coated film formed from the composition has good condition and is also superior in durability.

The invention relates to a particle containing at least 3 wt. % of pigment(s) in relation to the weight of the said particle.

The invention also relates to a series of particles, in which each particle contains at least 3 wt. % of pigment(s) in relation to the weight of the said particle, to a method for producing the said series of particles, and to the uses thereof in cosmetic compositions, particularly make-up for keratinous materials.

A coated powder comprises (a) particles, and (b) a coating on the surface of the particles including (1) silica moieties, (2) organo oxysilane moieties selected from the group consisting of mono-organo oxysilane moieties, bi-organo oxysilane moieties and tri-organo oxysilane moieties, and (3) poly(dialkyl)siloxane moieties. The amount by weight in SiO.sub.2 equivalents of the organo oxysilane moieties and the silica moieties is at least 0.0625% of the total coated powder weight per m.sup.2/g of the specific surface area of the particle to be coated.

Cosmetic body compositions, particularly in the form of a body moisturizer, are provided. The cosmetic body compositions comprise particles having encapsulated pigments which are capable of evening the body's skin tone by providing a pantyhose effect, improving its overall appearance, hydration, radiance and strengthening its barrier.

Ultraviolet radiation sun protective compositions are reported which feature micronized metal oxide inorganic particles selected from zinc oxide, titanium oxide and mixtures thereof, the inorganic particles being coated with poly [C.sub.8-C.sub.20 hydroxycarboxylic acid], the coated particles measured at a 10% loading in dodecane and 1 minute elapsed time having a Zeta Potential ranging from 2 to 10 mv, amounts of the poly [C.sub.8-C.sub.20 hydroxycarboxylic acid] to the inorganic particles being in a relative weight ratio of 1:100 to 1:10.
