The present invention relates to a process for the production of discrete solid extruded particles comprising dispersion droplets, to such particles as well as to the use of such particles in food, feed, pharmaceutical and personal care applications.

In a cosmetic composition according to the present invention, a coating membrane with a multilayer lamella structure is formed on the outside of ceramide particles by using phytosphingosine, and therefore, the cosmetic composition is stably present without ceramide precipitation even in formulations with low viscosity as well as high viscosity although the particles contain a high content of ceramide, and a cosmetic composition showing an excellent skin barrier recovery effect can be provided.

An encapsulated perfume composition in the form of a slurry comprising one or more core-shell capsules, dispersed in an aqueous dispersing medium, wherein the core contains a perfume and the shell contains a polyurea resin, and wherein the capsules are in the form of a stable suspension having a viscosity of up to 3000 centipoise, and more particularly about 150 to 3000 centipoise when measured on a rheometer, using rotating disks at a shear rate of 21 s.sup.−1 at a temperature of 25° C.

An encapsulated perfume composition wherein the shell contains a polyurea resin and the core contains a perfume comprising an aldehyde-containing perfume ingredient or ingredients, a non-aromatic cyclic perfume ingredient, and an alkyl salicylate and/or a 2,2,2-trisubstituted acetal,

A composition and method is provided for synthesizing silicone particles with narrow size distributions and tunable degrees of crosslinking for encapsulation of an active ingredient or multiple active ingredients in the matrix of the particles for controlled release. The method comprises agitating at least one type of silane monomer having two, three or four siloxane bonds in an acidic aqueous solution under conditions sufficient to allow for hydrolysis of the monomers, adding a catalyst and a solution comprising a co-solvent and the active ingredient(s) to the acidic aqueous solution, and continuing to agitate the combined solution to allow for a condensation reaction and formation of silicone particles with a narrow size distribution encapsulating at least a portion of the active ingredient(s). The tunable degree of crosslink density of the particles formed is based on the ratios of the monomers used, which enables controlled release of the active ingredient(s) from the particles.

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.

The invention comprises an emulsifier-free, skin-conditioning, cosmetic or dermatological preparation having a granular structure, characterized by contents of fatty alcohols and wax or paraffin for use on wet skin. The preparation is characterized by a special production method, which in turn only brings about the advantageous properties of a skin conditioning.

A nano-particulate composition comprising nano-particulate capsule comprising at least one or more of hydrophobic core material and a polymeric shell comprising homo-polymer or copolymers of at least one ethylenically unsaturated monomers or mixture thereof and having particle size distribution with an average article size in the range of 50 to 1000 nm is provided together with a controlled release delivery system comprising fragrance release delivery system involving said nano-particulate capsule water based emulsion and a process of manufacture thereof. Said delivery system provided is able to protect and release the fragrance in a controlled manner over a period of time. The controlled release fragrance delivery system of the present invention finds advantageous end use and application in fragranced consumer products formulations including water based coating/paint formulations and industrial formulations for use in industries including textile, cosmetics, soaps and detergents, leather industries.

In one aspect, the invention provides a method for treating a protein-containing surface, including applying to the surface a microcapsule suspension including droplets of a dispersed water-immiscible core phase, an aqueous continuous phase, and a wall surrounding each core phase droplet, the wall including the salt formed from at least one amphiphilic Lewis acid reactant or amphiphilic Lewis base reactant, and at least one corresponding Lewis base reactant or Lewis acid reactant.

A long lasting breath mint including a carrier and a flavorant, wherein the carrier includes at least one of a high viscosity cellulose ether and a low viscosity cellulose either and an alginate. The carrier forms a gel upon contact with saliva. A tablet is placed in the mouth of user, whereupon the tablet is wetted with saliva. A surface of the tablet is converted to a gel resulting in a tablet having an outer gel layer and a core. The gel serves as an adhesive for adhering the tablet to mouth structure. The gel slows exposure of the core to moisture and also slows diffusion of flavorant into the mouth of the user with the gel resulting in a breath mint having an extremely long life prior to complete dissolution, e.g., greater than 30 minutes or longer.
