The present invention relates to hydrogel particles coated with lipid, which are made from dispersing hydrogel particles in an organic solvent in which lipids are dissolved, and to a method for manufacturing same. Unlike the existing method for manufacturing hydrogel core vesicles, the present invention can effectively manufacture same by using an emulsification method, without involving the steps of chemical treatment of the surface of hydrogels or dilution, thereby facilitating mass production and preventing the decrease of drug encapsulation efficiency. The present method could be widely used for research on delivery carriers of oil/water-soluble active material or cell structure reproduction and more particularly, a keratinocyte mimetic of the present invention containing natural moisturizing factors can contain a large quantity of bound water for a long time, thereby exhibiting superior capability to retain moisture and moisturize, and providing a composition for an ingredient in cosmetics for moisturizing.

Provided is a treated platy substrate, a method of making it, and methods of using it. The substrate can be synthetic mica, optionally comprising metal-oxide layers. The treated platy substrate is useful in cosmetic compositions.

Ultraviolet radiation sun protective compositions are reported which feature micronized metal oxide inorganic particles selected from zinc oxide, titanium dioxide and mixtures thereof, the inorganic particles being coated with an adduct of a hydroxy cinnamate and a silanol, amounts of the adduct to the inorganic particles being in a relative weight ratio of 1:200 to 1:4.

A high-hydrophobic, low-bleeding color lake powder, a method for preparing the sane and a use thereof are provided. A color lake powder is dispersed into water, and a pH value of a system is adjusted to a range of 4 to 5.5. Then surface treating agents such as a silane coupling agent, a titanate coupling agent, a hydrogenated lecithin and an aliphatic acid are used to modify the color lake powder. Then pulverizing and drying the resultant to obtain the modified color lake powder.

Zinc oxide particles are prepared as a dry powder through a vapor phase formed by a plasma process, or by introducing defects into stoichiometric zinc oxide particles in a liquid carrier through mechanical stress. The zinc oxide has an O:Zn ratio of at least 0.99, an average particle size of 10 to 300 nm, and a sufficient concentration of oxygen vacancies and zinc vacancies to give a dispersion of the particles in C12-C15 alkyl benzoate an orange to tan color corresponding to a ΔE value of at least 15 in a Dispersion Color Test. The particles contain no aggregates and have no detectable particles 500 nm or larger, on a number-weighted basis.

A water-in-oil emulsified sunscreen cosmetic including the following components (A1), (A2), (B), and (C), with a content of (D) a non-volatile silicone oil being 0.1 mass % or more and 4 mass % or less, (A1) 5 mass % or more of a hydrophobized titanium dioxide fine particle, (A2) 10 mass % or more of a hydrophobized zinc oxide fine particle, (B) a divalent polyol, and (C) 2 mass % or more and 14 mass % or less of a non-volatile hydrocarbon oil, wherein each mass % is with respect to 100 mass % of the water-in-oil emulsified sunscreen cosmetic.

A non-pyrogenic preparation containing nanoparticles synthesized by magnetotactic bacteria for medical or cosmetic applications. 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.
