Shell-structured particles for sunscreen applications are provided herein. A composition includes one or more zinc oxide particles constituting a core material in a sunscreen composition, one or more particles coating the one or more zinc oxide particles, wherein each of the one or more particles comprises a band gap within a predetermined range, and wherein said one or more particles are selected based on a desired absorption spectrum of the sunscreen composition, and an anti-reflective coating applied to the surface of the one or more particles coating the one or more zinc oxide particles.

The present invention provides a color-changing microcapsule composed of a core comprising an inner color layer having a color, a pressure-breakable wall layer surrounding the core, an optional outer color layer and an optional outermost layer, characterized in that said core comprises a core-seed and at least one inner color layer comprising a colorant and a binder, and said pressure-breakable wall layer comprises titanium dioxide particles and a binder.

Said color-changing microcapsule has a high durability during storage and handling and a high masking ability of inner color, can be easily ruptured by pressing, rubbing, wiping and/or scrubbing with hand or an implement such as cloths, sponge or paper to reveal or develop the color on the inner color layer as well as can maintain the stability for a long time when incorporated into a carrier of cosmetic formulations.

A microcapsule composition is provided, which contains a polyurea or polyurethane microcapsule, an alkylnaphthalenesulfonate formaldehyde condensate, and polyvinylpyrrolidone. Also disclosed is a process of preparing the microcapsule composition and a consumer product having such a microcapsule composition.

The disclosure relates in general to macroscopic dispersions having high cationic polymer and pigment content, as well as to uses thereof in the cosmetic domain, and in particular to the uses thereof as a makeup composition, especially as foundation.

A plant oil preparation includes a plurality of particles, each of which including a core layer and at least one protective layer, the core layer including the plant oil, the protective layer encapsulating the core layer and including a phospholipid material and a surfactant; and a carrier, the plurality of particles being dispersed within the carrier. A preparation method for the plant oil preparation includes steps of: (1) mixing the phospholipid material in an aqueous phase to form a dispersion solution; (2) mixing the plant oil in the dispersion solution to encapsulate the plant oil by the phospholipid material and form a plurality of intermediate particles; (3) adding the surfactant, allowing the surfactant to attach to the plurality of intermediate particles and form the plurality of particles; and (4) adding the carrier and dispersing the plurality of particles within the carrier.

A method of forming microcapsules having improved physical properties and release control as well as the microcapsules formed by the process wherein the capsule wall is formed by the concurrent polymerization of monomers, oligomer and/or prepolymers on the inside of the capsule wall and different monomers, oligomers and/or prepolymers on the exterior of the capsule wall as it forms.
