Delivery of compositions for treatment of skin tissue with photoactive plasmonic nanoparticles and light, with embodiments relating to delivery devices. Treatments are useful for cosmetic, diagnostic and therapeutic applications.

This invention provides particles encapsulating colorant that do not produce functional effects or remove functional effects until they are triggered by contacting with at least one exogenous source. The particles in this invention minimize toxic effects the body of the colorant and the material that interacts with an exogenous source as well as minimize body chemicals from degrading both the colorant and the material that interacts with an exogenous source inside the particle.

To improve a fresh sense of use, an excellent feeling of use of hydrophobic powder, color development, transparency, ultraviolet shielding ability, and the like. In production of a cosmetic containing, respectively, 1 wt % or more of water and hydrophobic powder, (A) hydrophilic nonionic surfactant as monoether compound of branched higher alcohol having 12 to 20 carbons and polyoxyethylene group and (B) water are mixed, and then mixed with (C) hydrophobic powder.

A personal care composition comprises a personal care adjunct ingredient, an anti-dandruff agent, and cationic co-polymer disposed on an outer surface of the anti-dandruff agent. The cationic co-polymer has a viscosity of at least 0.09 poise and comprises monomers selected from the group consisting of acrylamide (“AAM”), dimethyl acrylamide (“DMAA”), acrylamidopropyl trimethylamonium chloride (“APTAC”), methacrylamidopropyl trimethylammonium chloride (“MAPTAC”), and combinations thereof.

Polyurea capsules that encapsulate active materials in polymeric walls resulting from the polymerization of an aromatic or aliphatic polyisocyanate and a cross-linking agent are provided as are consumer products containing said polyurea capsules and for methods for producing such capsules.

Provided are coated particles and methods of their use for providing healthcare benefits. More specifically, the present invention provides amino acid and/or polymer-coated particles, or particles coated with other materials, for binding to, or otherwise associating with, surfaces of the oral cavity.

A transparent composition having UV protection effect is provided, wherein the UV protection effect is improved after the composition is contacted with moisture, such as water or sweat, more than that immediately after the composition is applied, while maintaining high transparency. The transparent composition contains (a) a UV absorbent, (b) an oil component having a refractive index in the range from 1.5 to 1.7, (c) an oil component having a refractive index of not less than 1.3 and less than 1.5, and (d) a powder having a refractive index in the range from 1.45 to 1.55, wherein a mixed oil component obtained by mixing the (b) oil component having a refractive index in the range from 1.5 to 1.7 and the (C) oil component having a refractive index of not less than 1.3 and less than 1.5 has a refractive index in the range from 1.44 to 1.56.

Provided are: a hydrophilized inorganic powder having favorable properties while reducing the blending amount of a surfactant; and a cosmetic including the hydrophilized inorganic powder. A hydrophilized inorganic powder including an inorganic powder as a base material, a hydrophobic coat that covers the surface of the inorganic powder, and a hydrophilic coat that covers the hydrophobic coat, wherein the composition of the hydrophilic coat is a nonionic surfactant(s) having a hydrophilic moiety and a carbon chain moiety, and has a branched structure sufficient for imparting self-dispersibility in the carbon chain moiety is provided.

Disclosed are a method for preparing exosomes from bovine placenta, lyophilized powder of the exosomes, as well as a composition containing exosomes from animal placenta and a preparation method and use thereof in anti-wrinkle on skin.

Provided are coated particles and methods of their use for providing healthcare benefits. More specifically, the present invention provides amino acid and/or polymer-coated particles, or particles coated with other materials, for binding to, or otherwise associating with, surfaces of the oral cavity.
