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

The present invention relates to a multilayer UV filter particle, comprising: an odd number of alternating layers of high and low refractive index materials, wherein each layer has a refractive index that differs from that of adjacent layers by at least 0.2, the total number of layers is at least 9, and the particle does not contain a substrate. The particle according to the present invention can have a good UV filtering effect.

An aqueous liquid cosmetic containing 1 to 20% by mass of (A) a flake aluminum powder coated with a layer containing a silicon compound; 0.5 to 10% by mass of (B) a polycarboxylic acid-based dispersant having a mass-average molecular weight of 10,000 or less; and 1 to 40% by mass of (C) a film-forming polymer emulsion in terms of a solid content is provide. Normally, the aqueous liquid cosmetic contains at least 40% by mass of water, and further may optionally contain (D) a color pigment as another ingredient. This aqueous liquid cosmetic is suitable for eye makeup applications such as eyeliners, eyebrows, eye colors, and the like.

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.

The disclosure provides a peptide microparticle structure that can easily penetrate into the bottom layer of the skin. The peptide microparticle structure is composed, from inside to outside, of a main core, a first lipid layer, an active ingredient layer, and a second lipid layer. The main core is disposed at the center of the peptide microparticle structure, and the outer part of the main core is completely covered by the first lipid layer. The outermost layer of the peptide microparticle structure is the second lipid layer, and between the first lipid layer and the second lipid layer is the active ingredient layer.

The present invention relates to metal effect pigments with a high covering power and a thin iron oxide coating, for creating a champagne tone.

The present invention relates to a pigment mixture based on spherical particles having a defined particle-size distribution, and to the use thereof in paints, coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, in cosmetic formulations, as tracer, as filler and for the preparation of pigment preparations and dry preparations.

The instant invention relates to a composition for cosmetic raw material containing microcapsule containing at least one encapsulated material comprising at least one core and at least one layered coating surrounding said core, and the encapsulated material being at least one reflective particle. The invention further relates to a process for preparing the composition for cosmetic raw material containing microcapsule containing at least one encapsulated material comprising at least one core and at least one layered coating surrounding said core, and the encapsulated material being at least one reflective particle.

The present invention relates to dust-free preparations dispersible in cold water. These preparations consist of particles comprising water-insoluble or only sparingly water-soluble active substance(s), said particles being coated with one or more layers, the outermost layer comprising as principal component one or more hydrophobic powdering agents on which at least one dispersant is absorbed. The invention also relates to a process for producing these particles and to the use thereof in food supplements, foodstuffs, animal feeds, personal-care products, and medicaments.

A cosmetic composition is provided for application to the hair or skin, comprising 30 to 85% ethanol, 15 to 37% water, a crosslinked copolymer composed of acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols as monomers, the crosslinked copolymer being present in a total amount of 0.1 to 1.0%, a alkalizing agent up to a pH of the cosmetic composition in the range of 5 to 8, measured at 20° C., a substance selected from oils and fragrances in a total amount of 0 to 10%, one or more surfactants in a total amount of 0 to 0.1%, and at least one pigment in a total amount of 0.1 to 10%, where all quantities are based on the weight of the cosmetic composition, whereby the application is preferably done by spraying, especially preferably by spraying with a pump sprayer.
