Provided is a water-in-oil emulsified sunscreen cosmetic having easiness to spread while applying and is unlikely to decrease SPF value when the applied site is wet with water while containing a high content of the hydrophobized ultraviolet scattering agent.

A water-in-oil emulsified sunscreen cosmetic containing the following components (A), (B), (C), and (D): (A) 10 mass % or more and 50 mass % or less of a hydrophobized ultraviolet scattering agent, (B) a dipolyhydroxystearic acid ester of a polyhydric alcohol, (C) 35 mass % or more and 85 mass % or less of a liquid oil agent, and (D) water; wherein a mass ratio of the component (B) to the component (A), [(B)/(A)], is 0.01 or more and 0.2 or less.

To provide an oil-in-water type emulsified cosmetic comprising a pigment grade hydrophobically treated particle and a hydrophobically treated microparticle, which is capable of uniformly applying particles subjected to hydrophobization treatment on the surface of the skin and exhibiting a good tone-up effect and the like.

The oil-in-water type emulsified cosmetic of the present disclosure comprises a dispersion medium comprising water, and an oil droplet dispersed in the dispersion medium, wherein the dispersion medium comprises a nonionic surfactant, a polyhydric alcohol, and a pigment grade hydrophobically treated particle having an average particle diameter of 300 nm or more, wherein the oil droplet comprises an oil content , a nonionic surfactant, and a hydrophobically treated microparticle having an average particle diameter of 200 nm or less, and wherein the oil content comprises a volatile oil.

The present invention provides a solid personal care product comprising: a core layer containing a cleansing or conditioning component; and a skin layer containing a water-soluble or water-dispersible polymer. A solid personal care product produced according to the present invention solves the disadvantage that existing conventional solid cleansing agents or conditioning agents in powder, soap, or other flake form have of the powder scattering, as well as the problem of the cleansing power, conditioning efficacy, and fragrance-preserving property of such agents degrading. Moreover, the contents of the cleansing or conditioning component does not rub off onto the hands of a user even when the user holds the contents in the user's hands, and the shape of the product according to the present invention does not change even in places of high humidity. In addition, this solid personal care product is easy to use, store, and package, while retaining the same functions as those of conventional liquid cleansing and conditioning personal care products.

A shaving aid for razor cartridges comprising water soluble filaments having nano-sized diameters and exhibiting lubricating properties and with improved visual and tactile aesthetics, wherein said nano-filament has a core and a sheath.

This disclosure provides an encapsulated cleansing composition that is free of talc and that includes a core particle including (1) tapioca starch, (2) potato starch, (3) at least one anionic surfactant, and (4) at least one amphoteric surfactant. The encapsulated cleaning composition also includes a coating disposed about at least a portion of the core particle and includes a polysaccharide.

A temporary hair dye composition contains a soap base and a pigment. A method for temporarily coloring hair comprises mixing the temporary hair dye composition including the soap base and the pigment with water to generate a foam, and then applying the foam to the hair.

The present invention provides a nitric-oxide containing composite in the form of microparticles, wherein said microparticles comprise: (i) a core which comprises silica; (ii) a layer on said core which comprises a metal-organic framework; and (iii) nitric oxide;
