The present invention provides core-stabilized microcapsules, wherein said core comprises at least one active agent encapsulated within an inorganic oxide shell, processes for their preparations, comparisons comprising them and uses thereof.

A process for preparing microcapsules has an interconnected porous microsphere matrix The matrix includes at least one metal oxide and/or inorganic polymer. The microcapsules are obtained by a sol-gel process which involves preparing a first solution being a water-in-oil emulsion and adding to the emulsion a second acidic aqueous pre-hydrolyzed metal precursor solution and/or an organic polymer solution.

The present invention is directed to an aqueous dispersion comprising: (a) at least one solid wax particle having a particle size ranging from equal to or greater than 1 micron to about 100 microns and comprising at least one wax having a melting point of greater than 35 C.; (b) a surfactant mixture comprising at least one nonionic surfactant and at least one ionic surfactant; (c) at least one volatile solvent; and (d) water. The aqueous dispersion may be employed in compositions capable of delivering benefits to various substrates, for example, keratinous substrates such as skin and hair.

The instant invention relates to a composition for caring for and/or making up keratin materials comprising, in a physiologically acceptable medium, at least one microcapsule containing at least one encapsulated releasable material(s) said microcapsule comprising at least one core and at least one layered coating surrounding said core, and said encapsulated material(s) being at least one reflective particle, and being only released from said microcapsule(s) when said composition is applied onto a keratin material, such as keratin fibers or skin. The invention further relates to a cosmetic process for caring for and/or making up keratinic materials, comprising application on said keratinic materials in particular on the skin of a composition as defined above.

A microcapsule suspension for treating a protein-containing surface includes droplets of a dispersed water-immiscible core phase, an aqueous continuous phase, and a wall surrounding each core phase droplet. The wall includes the salt formed from at least one Lewis base reactant and at least one Lewis acid reactant, wherein at least one Lewis base reactant or Lewis acid reactant is amphiphilic and wherein at least one Lewis acid reactant is selected from the group consisting of proteins, protein hydrolysates, charged amino acids, and water-soluble salts of any of these.

Methods of making personal care compositions including microcapsules and methods of enhancing the efficacy of the microcapsules in said personal care compositions.

An object to be achieved by the present invention is to provide a pigment which is comfortable and smooth to the touch in a coating, spreads well on the skin, for example, when used in a cosmetic material such as a foundation or an eye shadow, and exhibits good color development and gloss. A pigment of the present invention is a coated pigment formed by coating a surface of a flaky base material made of at least one metal or metal oxide with a colorant. The surface of the flaky base material has a coarse particle area fraction of 9% or less. Further, it is preferable that the flaky base material be at least one or more selected from the group consisting of mica, aluminum, alumina, and glass.

Provided herein are compositions and methods comprising phosphonates, N-halamines or combination thereof for dental care. Specifically, for removing tartar (calculus), including mature tartar.

A composition, especially a cosmetic composition, in particular for making up and/or caring for keratin materials, including at least one aqueous phase gelled with at least one hydrophilic gelling agent; and at least one oily phase gelled with at least one lipophilic gelling agent chosen from organopolysiloxane elastomers; said phases forming therein a macroscopically homogeneous mixture. The composition also includes a dispersion of solid aggregates, said aggregates being formed from 10% to 80% by weight of wax(es), relative to their total weight. Also disclosed is a process for preparing such a composition.

The present invention relates to a core-shell network structure formed using a biocompatible biopolymer and to a composition comprising same. Said structure can be used as an alternative to synthetic chemical materials, such as polyethylene glycol (PEG), to effectively disperse an insoluble effective substance within a composition, thus addressing safety issues, and formulations can be preserved stably for a long time through said network structure. Furthermore, said structure and the composition comprising same may provide useful benefits for the skin in terms of skin barrier enhancement, skin moisturization, skin regeneration, or the like.
