Provided are: a core-corona polymer particle excellent in emulsion stability and feeling of use, and a raw material for a cosmetic and an oil-in-water emulsion cosmetic comprising the particle. The present invention provides a core-corona polymer particle obtained by radical-polymerizing a polyethylene oxide macromonomer represented by the formula (1) and one or two or more of hydrophobic monomers represented by the formulas (2) and (3) under the following conditions (A) to (D).

Anti-aging cosmetic compositions prepared from conditioned medium of adipose-derived stem cells are provided. The cosmetic compositions are preferably ready-to-mix compositions, comprising two separate components: a protein component in a dried form that serves as the cosmetically active ingredient of the product, comprising a protein fraction purified from an adipose-derived stem cell conditioned medium; and a reconstitution component, for reconstituting the lyophilized protein component just before application to the skin.

A toothpaste composition includes a structurant and a thickener, wherein the toothpaste composition has a predetermined viscosity and phase angle by using the structurant instead of reducing the content of a thickener, and thereby has an improved release property during use while maintaining a shape retention property of the toothpaste, and has an improved feeling of refreshment, flavor releasing power, cleaning power, and stain removal power. Further, provided is a toothpaste composition including a chelating agent containing phosphate and silica, wherein the chelating agent is supersaturated to precipitate phosphate to provide strong cleaning power, a whitening effect, a stain removal effect, and a crunchy sensation. Further, provided is a toothpaste composition including a peroxide, a thickener, and a spreading agent, wherein the peroxide and the thickener are separated from each other, providing excellent sense of use, stability, and a whitening effect in an anhydrous state.

A cleansing composition comprising a detersive surfactant; an aqueous carrier; from about 0.5% to about 30% by weight of the cleansing composition of discrete particles comprising anhydrous particles and an aqueous phase, and wherein said anhydrous particles comprise: one or more fatty amphiphile selected from the group consisting of fatty alcohol, fatty ester, fatty acid, fatty amide and mixtures thereof; of one or more secondary surfactants selected from the group consisting of anionic, nonionic, zwitterionic, cationic or mixtures thereof. Wherein the discrete particle of the cleansing composition has a size from about 500 microns to about 7000 microns, and wherein the cleansing composition has a % transmittance of about 75% or higher.

Described is an initial liquid composition with at least antimicrobial, antibacterial, and/or anti-viral properties comprising chelated metal oxide particles suspended in a polyol, such that metal oxide particles are homogeneously dispersed in a primarily liquid based polyol carrier so that chelated metal oxide particles form a stable complex suspension that is optionally an alkaline based aqueous silver oxide dispersion. The liquid composition can be subsequently added to any polymer or polymer compound/system where the polymer degrades or melts at a temperature lower than the polyol carrier degradation or boiling temperature. The metal oxide complex may also impart beneficial semi-conductive or conductive as well as permeability and flammability property changes to the polymer (host) system.

A tooth whitening and/or tooth sensitivity strip or film comprising: about 1-20 wt. % hydroxyapatite (HAP). A process for the manufacture of a tooth whitening strip or film, the process comprising at least the steps of: —mixing at least one or a combination of polyvinylpyrrolidone (PVP) polymers wherein the amount of the polyvinylpyrrolidone (PVP) polymers is greater than 75 wt. % of the film or strip; and —an amount at least about 1-20 wt. % hydroxyapatite (HAP); and —at least one or a combination of polycarbophils; —with water to provide an aqueous tooth whitening liquid; —applying the aqueous tooth whitening liquid to a substrate to provide a substrate carrying the aqueous tooth whitening liquid; —drying the aqueous tooth whitening liquid to provide a tooth whitening film on the substrate, said film having a thickness from about 50 pm to about 500 pm.

A skin treatment composition is described comprising a cryopreserved blend of natural materials including at least two components selected from the group consisting of wheat grass juice, wheat grass pulp, shea butter, cocoa powder, rice flour, coffee, jojoba oil, hemp oil, castor oil, and sugarcane juice. The skincare treatment composition is applied with a specialty applicator that is frozen into the compound during processing. Methods of making, packaging and using the compositions also are disclosed.

A cosmetic composition containing rose stem cell-derived exosomes as an active ingredient is provided for skin regeneration, skin elasticity improvement or skin wrinkle reduction. The cosmetic composition has excellent effects on skin regeneration, skin elasticity improvement and/or skin wrinkle reduction.

A medical device or solution for treating dental discomfort by at least partially occluding dental tubules is disclosed. The medical device or solution contains a polysaccharide or other biocompatible polymer with an antimicrobial metal, antimicrobial metal compound, or antimicrobial metal ion bound to a biopolymer. The medical device or solution further comprises at least one soluble antimicrobial. The soluble antimicrobial may be a water soluble metal iodide, water soluble metal fluoride, or a water soluble metal chloride encompassed with the nanogel. The medical device may be a solution of a chitosan with a nanoparticle of silver fluoride on the chitosan and at least one of a sodium fluoride or silver fluoride. The solution may be water based solution. Methods of applying the medical device or solution are also disclosed.

Particulate aerogel material kit for grip enhancement, and related systems and methods, are generally described. Certain embodiments are related to interfaces comprising human skin, a layer of particulate aerogel material, and a solid surface. Methods of creating such interfaces, packaging the particulate aerogel material, and applications thereof (including kits for grip enhancement) are also described.
