The nanoparticles are constituted by a crystallized mineral central part including predominantly an iron oxide, as well as a surrounding coating without material from the magnetotactic bacteria.

Provided is an oral composition containing particles that have properties to seal dentinal tubules and excellent adhesion properties in dentinal tubules. Specifically, provided is an oral composition containing hydroxyapatite particles, wherein the hydroxyapatite particles have a ratio of a diffraction peak intensity around 2θ=32° to a diffraction peak intensity around 2θ=26° of 0.8 to 1.6 in an x-ray powder diffraction pattern as measured with CuKα characteristic X-rays.

Disclosed herein is zinc/amino acid functionalized silica, compositions comprising the same, and oral care methods and uses for such compositions.

The present disclosure relates to a skin film forming agent, and provides a skin film forming agent which comprises dimethiconol, hydride dimethicone and a cross-linking component, and thereby provides a skin film forming agent which has no problem of safety, and forms a film with high intensity, and thereby can solve peeling and slipping of the film and effectively improve skin disadvantages, particularly, wrinkles and elasticity.

Disclosed a method of preparing composite particles comprising a non-porous spherical particulate inorganic material deposited on a plate-like inorganic material, where refractive index of said particulate inorganic material is greater than that of said plate-like inorganic particulate material, wherein, said spherical material occupies 20 to 80% of total surface area of said plate-like material and wherein the amount of said spherical material accounts for 2 to 20 wt % of said composite particles, further wherein said plate-like inorganic material is mica and said non-porous spherical particulate inorganic material is silicone dioxide, said method comprising the steps of: (iv) silanization of said plate-like inorganic material to get a silanized material having functional groups “A”; (v) silanization of said non-porous spherical particulate inorganic material to get a silanized material having functional groups “B”, where A≠B; and where said “A” and said “B” are capable of reacting with each other such that by way of their reaction, said non-porous spherical particulate inorganic material deposits on said plate-like inorganic material; and, (vi) reacting said silanized material having functional groups “A” with said silanized material having functional groups “B”.

The present invention relates to isopropylparabene free topical compositions comprising a specific polyester and at least one inorganic UV-filter. Furthermore, the present invention relates to the use of the combination of such polyesters and inorganic UV-filters to reduce the stickiness of compositions comprising either the polyester or the inorganic UV-filter.

Embodiments herein provide a cosmetic or dermatologic composition comprising a plurality of multiparticulated particles, wherein the multiparticulated particles comprise a plurality of coated active ingredient particles, each coated particle comprising at least one active ingredient having a core and a coating thereon. The multiparticulated particles further comprise a plurality of uncoated active ingredient particles, the uncoated particles comprising at least one active ingredient having a core. In further embodiments, the coated particles and the uncoated particles have the same or different active ingredient cores. The present invention further provides a method of protecting skin or hair by applying the cosmetic composition according to the invention.

Cosmetic agents for the temporary color change of keratinous surfaces, in particular human hair and human skin, contain an alcohol having 2 to 8 carbon atoms, a special anionic polymer, and a pigment. These cosmetic agents have an extremely good water resistance but can be removed without residue with a single application of surfactant-containing detergents. In addition, methods of temporary staining keratinous fibers and the skin using these agents are provided.

The present invention relates to a mesh-type moisture-release cushion cosmetic product and, more specifically, to a mesh-type moisture-release cushion cosmetic product having a cosmetic container, which has a mesh net mounted at the upper part thereof and is filled with a water-in-oil moisture-release cosmetic composition comprising: an oil phase part including wax, oil, and a mixture-emulsifying agent comprising a combination of a main emulsifying agent and an auxiliary emulsifying agent; a water phase part including water; and a powder part including hollow-structured gloss pigments.
