Abstract: A one-phase microemulsion composition, which can be easily prepared without the use of special equipment, has high safety, and stays stable for a long period in an ultrafine emulsion state when the composition is added to an aqueous formulation, is provided by appropriately adjusting the ratio of (A) a hydrophilic nonionic surfactant, (B) a lipophilic nonionic surfactant, (C) an oil component, (D) a water-miscible solvent that does not interdissolve with the oil component, and the critical micelle concentration (CMC) of the hydrophilic nonionic surfactant in the water-miscible solvent is higher than that of the hydrophilic nonionic surfactant in water, and (E) water.

Abstract: The cosmetic of the present invention is a cosmetic that alleviates skin irritation by blending in polypropylene glycol, a specific polar oil, or polybutylene glycol, as well as an ultraviolet absorbent. The present invention also relates to an agent and a method for alleviating irritation by lipophilic drugs. Since the present invention alleviates skin irritation due to ultraviolet absorbents and lipophilic drugs in cosmetics, any amount of ultraviolet absorbents and lipophilic drugs can be blended in cosmetics, and therefore cosmetics that can fully manifest their effects can be provided. Also, it is possible to prepare a safe sunblock cosmetic with superior ultraviolet protection effects because the ultraviolet absorbent is not absorbed through skin.

Abstract: This invention relates to cosmetic, in particular, relates to improvements of retaining performance and film-line feeling of makeup cosmetic for lips, eyelashes and skin, makeup cosmetic, and improvements of emulsion stability and dispersibility of powder in water-in-oil emulsion cosmetic. This invention is to provide cosmetic comprising a copolymer comprising specific acrylic acid monomer (A), specific polyoxyalkylene monomer (B) and specific organopolysiloxane monomer (C) as constituting monomers, wherein the content of monomer (A) is 20% by mass or more relative to the total amount of the constituting monomers.

Abstract: The present invention is a skin treatment composition that characteristically contains an alkyl benzoate represented by the following general formula (1). This provides a skin treatment composition that gives a refreshing sensation at the time of application and can contain drugs and ultraviolet absorbents in a stable manner. Also, the present invention is a sunblock water-in-oil type emulsified cosmetic characteristically comprising an ester bond product of polyhydroxystearic acid represented by the following general formulas (2) or (3), alkyl benzoate represented by the following general formula (1), and an ultraviolet absorbent. This provides a sunblock cosmetic consisting of a water-in-oil type emulsified composition that can contain an ultraviolet absorbent in a stable manner and exhibits a superior usability. (In this formula, R denotes a branched or straight chain alkyl group having 8-15 carbon atoms.

Abstract: A base for a skin external composition comprises, as a main ingredient, an alkylene oxide derivative represented by the following formula (I): R1O—[(AO)m(EO)n]—R2??(I) wherein AO is an oxyalkylene group having a carbon number of 3 to 4; EO is an oxyethylene group; and R1 and R2 may be the same or different, and are a hydrocarbon group having a carbon number of 1 to 4, or a hydrogen atom. The base is a water-soluble base that can exert both of the smooth feeling and the moist feeling.

Abstract: A skin treatment composition that characteristically contains alkylene polyglycol dineopentanoate having a specific structure.

Abstract: A skin treatment composition of the present invention is an external composition for skin comprising an alkylene oxide derivative expressed by Formula (I):

Abstract: An endermic liniment comprising a polyoxyethylene dicarboxylate represented by the following chemical formula (1). (In this formula, R1 and R2 are hydrogen or alkyl or branched alkyl groups having 1-4 carbon atoms, and m, n, X, and Y are integers 0-5 which are not all zero at the same time. R3 is a branched or linear chain alkylene group having 0-10 carbon atoms.) The endermic liniment of the present invention achieves superior tactile sensation during use, smoothness in particular, without a sticky sensation, while maintaining a lasting moisture retaining effect by means of blending in a humectant and a polyoxyethylene dicarboxylate.

Abstract: An endermic liniment comprising a polyoxyethylene dicarboxylate represented by the following chemical formula (1).

Abstract: Cleansing agents are provided which are highly effective for removing makeup with excellent lathering, while at the same time providing a refreshing after-shampoo feeling. These cleansing agents comprise surfactants and polyoxyalkylene carboxylic acid esters represented by the following formula (1): wherein R1 and R2 are hydrogen or straight or branched chain alkyl groups having 1 to 4 carbon atoms; m, n, X and Y are integers of from 0 to 5 but are not all concurrently 0; and R3 is a straight or branched chain alkylene group having from 0 to 10 carbon atoms.

Abstract: Cleansing agents are provided which are highly effective for removing makeup with excellent lathering, while at the same time providing a refreshing after-shampoo feeling.

Abstract: An emulsion compositions comprising (i) an alkyl-modified carboxyvinyl polymer, (ii) a C.sub.12 to C.sub.18 higher alcohol solid at room temperature (for example 15.degree. to 20.degree.
