Provided is a powder material for a cosmetic that has excellent dispersibility in any of silicone oil agents, hydrocarbon oil agents, and ester oil agents, and does not affect the color appearance of a formulation. The powder material for a cosmetic contains a powder for a cosmetic surface-treated with an ester compound of a fatty acid having 8-20 carbon atoms and glycerol. The ester compound is at least one selected from the group consisting of diglyceryl tetraisostearate, diglyceryl triisostearate, glyceryl tri(caprylate/caprate), glyceryl dilaurate, glyceryl triisostearate, decaglyceryl monoisostearate, and decaglyceryl diisostearate.

An aqueous, particle-stabilized Pickering emulsion along with methods or processes for producing the same and particles produced therefrom.

Semisolid oral dispersions for improving the health and/or appearance of the oral cavity. The semisolid oral dispersions include hydrophilic active agent particles in hydrophobic phase. The hydrophilic active agent particles can include bleaching agents, antimicrobial agents, anticalculus agents, and/or combinations thereof. The hydrophilic active agent particle can have a solubility in water of at least about 20 parts, by weight of the particles, in about 100 parts, by weight, of water. The hydrophobic phase can be semisolid petrolatum.

Cosmetic and dermatological compositions, including color changing compositions, are provided which typically include a plurality of synthetic particles having a size in the micrometer or nanometer range. Each synthetic particle typically includes one or more aggregates of a pigment selected from phenoxazone, phenoxazine, and a derivate or precursor thereof, and a stabilizing material which has a refractive index larger than 1.45; the aggregates having a size larger than about 100 nm and the composition being biodegradable and biocompatible.

The present invention relates to an emulsion not containing any emulsifying surfactant, in particular to an oil-in-water emulsion not containing any emulsifying surfactant, characterized in that it comprises, especially in a physiologically acceptable medium, at least composite particles comprising a core comprising at least organic or inorganic particles A; said core being covered at the surface, continuously or discontinuously, with an envelope comprising at least organic or inorganic particles B; said particles A and B having different polarities.

According to the present disclosure, a method of preparing polymeric microparticles comprising further crosslinking with an organic crosslinking agent after crosslinking with metal ions, polymeric microparticles, medical compositions, cosmetic compositions, medical articles and cosmetic articles comprising the same can be provided.

There is provided a method of preparing a hybrid capsule, the method comprising heterocoagulating organic polymer latex particles with a primary capsule to form an organic polymer coating layer over a shell of the primary capsule.

Disclosed is a cosmetic composition comprising: (i) microspheres for providing soft-focus benefits where said microspheres comprise at least 50% cellulose by weight of microspheres; and, (ii) 0.5 to 10 wt % of a non-silica hydrophilic inorganic thickener; wherein refractive index of said microspheres is from 1.42 to 1.50.

Provided is a polyurethane gel composition containing A and B below. Here, A represents a polyurethane obtained by reaction of (a) a hydrogenated polybutadiene having isocyanate groups at the terminals and (b) a glycol represented by HO—R.sub.3—OH (wherein R.sub.3 represents a linear or branched C2 to C6 alkylene group optionally having an ether bond), or A represents a polyurethane obtained by reaction of (c) a hydrogenated polybutadiene having hydroxyl groups at the terminals, (d) a diisocyanate compound, and the (b) glycol represented by HO—R.sub.3—OH (wherein R.sub.3 represents a linear or branched C2 to C6 alkylene group optionally having an ether bond), and B represents an oil agent. The polyurethane gel composition of the present invention is particularly useful as a raw material for cosmetics since a film of an oil-soluble gel obtained using the polyurethane gel composition is exceptionally excellent in any point of transparency, high gloss, elasticity, and resilience.

Pressed powder compositions are provided. The compositions include at least about 80% by weight of a mineral portion. The mineral portion comprises at least one alkylsilane-coated mineral; polyhydroxystearic acid, synthetic mica, and less than about 12% by weight of binding agents. Methods of shadowing the eyes and methods of forming pressed powder compositions are also provided.
