Another object is to provide a skin cleanser excellent especially in usability and a cosmetic removing effect. That is, the external skin preparation of the present invention is characterized by comprising a block-type alkylene oxide derivative represented by the below-described formula (I).
[formula 1] Y-[O(EO) a -(AO) b -(EO) o -R] k (I)
(In the formula, Y is the residue given by removing hydroxyl groups from a polyhydric alcohol having 3 to 6 hydroxyl groups, and k is the number of hydroxyl groups of the polyhydric alcohol. EO is an oxyethylene group, AO is an oxyalkylene group having 3 to 6 carbon atoms, and they are attached in a block-type, respectively. The products, a×k, b×k, and c×k, are the average addition mole numbers of the oxyethylene group, the oxyalkylene group having 3 to 6 carbon atoms, and the oxyethylene group, respectively, and 0 ≦a×k≦ 100, 1≦b×k≦ 100, and 0≦c×k≦ 100, however, (a+c)×k>1. The percentage of all oxyethylene groups in formula (I) with respect to the sum of all oxyethylene groups and oxyalkylene groups having 3 to 6 carbon atoms in formula (I) is 10 to 80 mass %. Rs may be either identical to or different from each other, and they are hydrocarbon groups with 1 to 4 carbon atoms.) The skin cleanser of present invention is characterized by comprising 0.01 to 70 mass % of a block-type alkylene oxide derivative represented by the above-described formula (I) and 0.1 to 20 mass % of a moisturizer.

The present invention is to provide a new surfactant that can be used as an emulsifier excellent in emulsion stability and texture in use and as a cleanser excellent in cleansing power and texture in use and having low skin irritation. A surfactant consisting of a compound represented by the below-described general formula (1).
Y-O-(EO) l -(AO) m -(EO) n -X (1)
(In the formula, AO represents an oxyalkylene group having 3 to 4 carbon atoms; m is the average addition mole number of the oxyalkylene group and satisfies 5≦m≦100. EO represents an oxyethylene group; 1 and n are the average addition mole numbers of the oxyethylene groups and satisfy 0≦1≦4 and 0≦n≦4. Either X or Y or both are a functional group represented by -SO 3 M, -COOM, -HPO 3 M, -(CH 2 ) q -SO 3 M, or -(CH 2 ) q -COO, wherein M is a hydrogen ion or a monovalent inorganic or organic cation, and q is the number of carbon atoms of the linked alkylene group and satisfies 1≦q≦4. When either X or Y is the above-described functional group, the other one can be a hydrogen atom, a methyl group, or an ethyl group.)

The present invention is a sunscreen cosmetic comprising hexyl diethylaminohydroxybenzoylbenzoate and a benzotriazole derivative represented by the following general formula (I).
(In this formula, R' = a straight chain alkyl group of C1-C6 and R" = a straight chain alkyl group of C1-C3.) The object of the present invention is to provide a sunscreen cosmetic that prevents staining due to secondary adhesion to clothing.
摘要:
It is intended to develop a film agent made of a novel amphoteric urethane resin and apply to cosmetics, in particular, hair cosmetics and external preparations for the skin. Namely, cosmetics characterized by containing an amphoteric urethane resin carrying a polysiloxane compound. Thus excellent cosmetics which can fully exert the film properties of the novel polysiloxane−carrying amphoteric urethane resin can be obtained. In case of hair cosmetics, for example, a favorable elasticity of the hair and excellent brushing properties without causing flaking can be established. In case of skin cosmetics, a moist and smooth feel and an appropriate elasticity can be imparted to the skin.

In a first aspect thereof, the present invention provides a method for treatment and/or prevention of a disease selected from the group consisting of psoriasis and squamous cell carcinoma by inhibiting the expression of squamous cell carcinoma antigen (SCCA) by cells. In another aspect thereof, the present invention provides a method for screening for substances that inhibit epidermal parakeratosis, wherein the activity of a candidate substance that inhibits cysteine protease inhibitory activity possessed by squamous cell carcinoma antigen 1 (SCCA-1) is used as an indicator.
摘要:
An oil based composition for external use on skin for enhancing percutaneous absorption of a water-soluble agent contains 50% by mass to 95% by mass of an oil constituent, which contains 10% by mass to 100% by mass of a solid or semisolid oil constituent, and 5% by mass to 50% by mass of particles. The composition has occlusivity of at least 50% and is adapted for use such that, after a preparation for external use on skin, which preparation contains a water-soluble agent, has been applied onto skin, the composition may be applied onto the preparation for external use on skin, which preparation has been applied onto the skin. A method of enhancing percutaneous absorption of a water-soluble agent utilizes the composition.

摘要:
The present invention provides a method for enhancing resistance to the onset of skin damage caused by irradiation of the skin with ultraviolet light by inhibiting ultraviolet irradiation-induced apoptosis of epidermal cells as a result of increasing expression of SCCA-1 and/or SCCA-2 in epidermal cells. Moreover, the present invention provides a skin testing method for evaluating resistance of the skin to skin damage caused by ultraviolet irradiation by measuring the expression of SCCA-1 and/or SCCA-2 in epidermal cells, and judging UV resistance of the epidermis to be weak in the case expression is decreased as compared with expression in epidermal cells. Moreover, the present invention provides a method for screening drugs which enhance resistance of the skin to skin damage by ultraviolet irradiation by selecting a drug that increases expression of SCCA-1 and/or SCCA-2 as a UV resistance enhancer.
