The purpose of the present invention is to provide a stick cosmetic that has a stick shape and a novel function that allows said stick cosmetic to be used to replenish moisture throughout the day. The present invention relates to a stick cosmetic for moisture replenishment, said stick cosmetic comprising: (A) 0.01-50 mass% of a fluid volatile oil component; (B) 10 mass% or more of water; (C) a wax that is capable of gelating the fluid volatile oil component; (D) a silicone elastomer; and (E) a silicone-based surfactant. The cosmetic of the present invention preferably further comprises (F) a moisturizing agent. The cosmetic of the present invention is suitable for use in touching up makeup and has a stick shape that exhibits excellent portability.


The present invention addresses the problem of providing a novel method for the pretreatment of a biological sample containing lenalidomide enantiomer and thereby establishing a simple and accurate method for the quantitative analysis of lenalidomide enantiomer. In the present invention, the racemization and decomposition of lenalidomide enantiomer in a biological sample can be prevented by the deproteinization under acidic conditions of the biological sample containing lenalidomide enantiomer, and the lenalidomide enantiomer can be simply and accurately quantitatively analyzed by subjecting to HPLC the biological sample that has been pretreated in such a way.

The present application provides an oil-in-water type emulsified cosmetic which has the effect of beautifying the appearance of skin and also excels in emulsion stability. The oil-in-water type emulsified cosmetic according to the present invention is characterized by comprising (A) 1 to 20 mass% of a hydrophobized titanium oxide having an average particle size of at least 0.1 m; (B) a sugar ester having a carboxyl group within the structure; (C) a liquid higher fatty acid; (D) a higher alcohol; (E) a non-ionic surfactant; (F) water; and (G) an oil component.


Sunscreen products that do not require the use of organic, ultraviolet-absorbing agents are provided. Effective protection of the skin from ultraviolet light is attained by increasing the amounts of titanium dioxide and zinc oxide. To mask the excessive whiteness that would otherwise result from the oxides, the sunscreen products contain multilayer-type encapsulations containing pigments. Before use, the pigments are enveloped in capsules that muffle the pigments color. When the sunscreen product is applied to the skin, the capsules break and the pigments are released to counter the excessive whiteness due to titanium dioxide and zinc oxide. Sunscreen product precursors, from which these sunscreen products can be generated by stirring, are also provided. A sunscreen product package contains the sunscreen product precursor and a stirring ball. A method of ultraviolet protection is provided by shaking the sunscreen product package and applying the sunscreen product thus generated to the skin.

The present invention relates to a water-based cosmetic wherein a hydrophobic powder is directly dispersed in the water phase of the water-based cosmetic, the water-based cosmetic having the excellent smoothness, water resistance and cosmetic durability characteristic of hydrophobic powders, while maintaining the refreshing sensation of use that is inherent in water-based cosmetics. The invented water-based cosmetic is characterized by comprising: (A) 0.1 to 5 mass% of a polyether-modified silicone having an HLB (Si) of 5 to 14; (B) one or more hydrophilic thickeners; (C) a polyol and/or an ethyl alcohol; and (D) one or more hydrophobic powders chosen from among metal oxides hydrophobically treated without using a metal soap, hydrophobic organic powders and silicone powders; wherein the (D) hydrophobic powder is dispersed in the water phase.

The purpose of the present invention is to provide an oil-in-water emulsion composition exhibiting high UV-protective capabilities with which it is possible to uniformly and stably disperse a hydrophobized metal oxide into an inner phase (oil phase) without detracting from the inherent fresh sensation on use of an oil-in-water emulsion composition even when a high amount of the hydrophobized metal oxide is compounded therewith. In summary, the present invention is an oil-in-water emulsion composition characterized by including (A) 0.1-5 mass% of polyether-modified silicone having an HLB(Si) of 5-14, (B) one or more hydrophilic thickeners, (C) a metal oxide hydrophobized by an agent other than metal soap, and (D) nonvolatile oil other than silicone oil, the (C) hydrophobized metal oxide being present in the inner phase.


The present invention provides an intermediate composition enabling to prepare easily and steadily an -gel-containing O/W emulsion cosmetic that has a very small viscosity change over time and is excellent in emulsion stability, without using a cooling device that has a heavy burden on cost and the environment, and a production method thereof. An -gel intermediate composition consisting of (A) 20 to 80 mass% of a mixture containing one or more higher alcohols having 16 or more carbon atoms and a nonionic surfactant with an HLB value of 7 to 17 in the mole ratio of 3:2 to 5:1, and (B) 20 to 80 mass% of a mixture containing one or more water-soluble solvents having the IOB value of 1.5 to 3.5 and water in the mass ratio of 4:6 to 8:2, andwherein the composition is a liquid consisting of a bicontinuous microemulsion phase or a lamellar liquid crystal-dispersed bicontinuous microemulsion phase at 50 to 80 C and a solid at room temperature.
