An oil-in-water cosmetic composed of an aqueous phase and an oil phase and comprising hydrophobized inorganic powder, a fatty acid soap, a nonionic surfactant and a hydrophilic polymer, including an oil that contains a non-silicone oil and including hydrophobized iron oxide powder and hydrophobized pigment-grade titanium oxide powder in the oil phase and the aqueous phase, wherein the contents of the hydrophobized pigment-grade titanium oxide powder in the oil phase and in the aqueous phase are, respectively, greater than 0.5 mass % and less than 5 mass %, and greater than 2.5 mass % and less than 20 mass %, the nonionic surfactant has an overall HLB value of 6 to 15, an aminoalkylsulfonic acid polymer is contained as a hydrophilic polymer, and the total non-silicone oil content is greater than 5 mass % and less than 30 mass %.

Disclosed are a sunscreen composition containing surface-defected cerium oxide particles and a method for preparing the sunscreen composition. The sunscreen composition containing surface-defected cerium oxide particles has excellent ability to kill bacteria, may have a high sun protection factor (SPF) and a high PA index, and may exhibit excellent dispersion stability since the layer separation thereof does not occur even after a long period of time elapses.

In a zinc oxide powder of the present invention, a content of a water-soluble substance is 0.30% by mass or less, and a mass ratio between an alkali metal and an alkaline earth metal which are included in the water-soluble substance is in a range of 1:2 to 10:1.

The present invention relates to a method for increasing sun protection factor (SPF) of a sunscreen composition, use of porous metal oxide spheres (e.g., microspheres) for increasing SPF of a sunscreen composition and preparation of sunscreen compositions comprising the porous spheres.

To provide a novel cosmetic, comprising a UV wavelength conversion substance and a water-soluble thickener.

The invention provides a particle comprising a lipid core and surface-decorated (nano)particles of at least one stabilizing material, for delivery of active agents.

Multi-coated nanoparticles including multiple coating layers of chitosan and polyglutamic acid, composition for skin care including the same, and method of manufacturing the same are provided. The nanoparticles have a liposome core layer and coating layers. The core layer includes a bioactive particle and a core hydrogel. Not only is it easy to mass-produce, but also has the effect of steadily releasing bioactive particles for a long period of time due to its high sealing rate and high stability.

The embodiments relate to titanate crystal particle dispersions, methods of making the dispersions, and compositions and uses thereof. The dispersions and compositions containing the dispersions provide a high coverage to the skin and high near infrared/infrared (NIR/IR) reflectance. The dispersions include optionally surface treated titanate crystals used as cosmetic powders, and a cosmetically acceptable dispersing medium. The dispersions may be useful in cosmetic compositions as a foundation and/or as a composition to correct skin discoloration, and may be used protect the skin from sun exposure.

The embodiments relate to cosmetic powder materials and compositions containing them that provide a high coverage to the skin and high near infrared/nitrated (NIR/IR) reflectance. The compositions include optionally surface treated titanate crystals used as cosmetic powders, and a cosmetically acceptable carrier. The compositions may be useful as a foundation and/or as a composition to correct skin discoloration, and may be used protect the skin from sun exposure.

A dispersible powder including an organopolysiloxane elastomer powder treated with a surface treatment agent. The surface treatment agent is an organopolysiloxane having a polyoxyalkylene group, a weight-average molecular weight of 300 to 300,000, and an HLB of 8 to 18. Thus, an organopolysiloxane elastomer powder has excellent dispersibility and high over-time dispersion stability in an aqueous medium; and a cosmetic can be blended with the powder.
