This scrub agent is in particle form with a plurality of vertices and has a median of particle size distribution set to a value in a range of from 0.1 mm to 1.0 mm.

A solid particle ranging from 0.001 to 200 microns in diameter coated with Indium Tin Oxide (“ITO”) and a topical composition containing same as well as a method for protecting skin against IR radiation.

Method for encapsulating a hydrophilic or amphiphilic biological compound, particles obtained by said method, compositions comprising them and uses thereof are disclosed.

A cosmetic composition containing sucrose esters, lauroyl lysine, and water. The composition meets at least one of the following conditions: (i) the weight ratio between the sucrose esters and lauroyl lysine is from about 5:1 to about 1:10; (ii) the lauroyl lysine has a mean particle size of from about 10 microns to about 40 microns; and (iii) the lauroyl lysine has a flat polygonal shape. The cosmetic composition can provide benefits from sucrose esters with reduced heavy coated feel, reduced sticky/tacky feel, and/or reduced friction/draggy feel.

Ultraviolet radiation sun protective compositions are reported which feature micronized metal oxide inorganic particles selected from zinc oxide, titanium dioxide and mixtures thereof, the inorganic particles being coated with an adduct of a hydroxy cinnamate and a silanol, amounts of the adduct to the inorganic particles being in a relative weight ratio of 1:200 to 1:4.

A solid or hollow particle ranging from 0.001 to 200 microns in diameter coated with Indium Tin Oxide (“ITO”) and a topical composition containing same as well as a method for protecting skin against IR radiation.

The present invention relates to a lipolysis composition comprising a biocompatible polymer that is surface-modified by an adipocyte-targeting or cell-penetrating peptide; and surface-modified gas-generating nanoparticles that contain fine-grained calcium carbonate crystals enclosed in the biocompatible polymer.

The invention provides a particle having an uneven structure on a surface thereof, and containing cellulose or a cellulose derivative and a clay mineral as main components, and a method for producing the same. Such a particle is soft and excellent in light scattering properties, and in particular, is excellent in a defocusing effect when it is formulated in cosmetics such as foundations, so that it is useful as cosmetics.

The subject of the present invention is a cosmetic composition of oil-in-water type comprising: (1) hydrophobic silica aerogel particles having a specific surface area per unit of mass (S.sub.M) ranging from 500 to 1500 m.sup.2/g and a size, expressed as volume-average diameter (D[0.5]), ranging from 1 to 1500 μm ; (2) at least one gemini surfactant of formula (I): ##STR00001##
in which R.sub.1 and R.sub.3 denote, independently of one another, an alkyl radical containing from 1 to 25 carbon atoms; R.sub.2 denotes a spacer consisting of a linear or branched alkylene chain containing from 1 to 12 carbon atoms; X and Y denote, independently of one another, a —(C.sub.2H.sub.4O).sub.a—(C.sub.3H.sub.6O).sub.bZ group; n ranges from 1 to 10 ; and (3) at least one fatty phase comprising at least one fatty substance chosen from solid fatty substances and pasty fatty substances. The composition in accordance with the invention makes it possible to make good the lack of cutaneous lipids in dehydrated skin, and to provide comfort and persistent nutrition, while at the same time having sensory properties, for example a non-greasy and non-tacky effect and a matt skin appearance, and also good skin penetration properties, even with a high level of solid fatty substance.

A powder is disclosed including a first powder of core/shell particles having an average particle size of less than 1000 microns, each particle contains a liquid core that is substantially free of water that includes a polar liquid having a percent surface polarity of at least 24%; and a shell comprising hydrophobic particles and a second powder including a color cosmetic.
