摘要:
A method for producing a composition containing a wax as its primary component, characterized in that it comprises admixing said wax and a material to be mixed with said wax through applying an external force at a temperature at which the melting of said wax is not completed.
摘要:
An amine derivative of following general formula (I) or (II) (wherein R1 represents a heteroatom-containing C¿1?-C40 hydrocarbon group which may have a ring structure, etc.; R?2 to R6¿ each represent a C¿1?-C10 hydrocarbon group, hydrogen, etc.; A?1¿ represents (i) or R?15-Z-R16(CH¿2)n-; B1 represents hydrogen, a C¿1?-C10 hydrocarbon group, nitrogen, etc.; and C?1¿ represents hydrogen, a C¿1?-C10 hydrocarbon group, nitrogen, alcohol residue, phosphoric acid residue, etc.); a dermatologic preparation containing the same; and a process for producing the amine derivative. The amine derivative has excellent effects of smoothing wrinkles and improving keratodermia.
摘要:
A fluorine-modified polysiloxane derivative having an organopolysiloxane chain partially replaced by a siloxane chain represented by general formula (1), (2), (3), a process for the production thereof, an intermediate to be used for the production thereof, and a cosmetic containing the same, wherein Rf and Rf' represent each C1-C20 perfluoroalkyl or omega -H-perfluoroalkyl of the formula H(CF2)t- wherein t represents an integer of 1 to 20; a number of R groups may be the same or different from each other and each represents C1-C20 linear or branched aliphatic hydrocarbyl or C5-C10 cycloaliphatic or aromatic hydrocarbyl; R represents hydrogen, C1-C20 linear or branched aliphatic hydrocarbyl, C5-C10 cycloaliphatic or aromatic hydrocarbyl, C1-C20 perfluoroalkyl or omega -H-perfluoroalkyl of the formula H(CF2)u- wherein u represents an integer of 1 to 20; R represents a C2-C10 divalent hydrocarbon group; X and Y represent each a single bond, -CO- or a C1-C6 divalent hydrocarbon group; l represents a number of 2 to 16; m and n represent each a number of 1 to 6; and r represents a number of 0 to 50. A cosmetic containing this compound has excellent water and oil repellency, can be held on the skin for long, and is comfortable to use.
摘要:
A hairdye composition which comprises a mixture of a first ingredient comprising an alkali agent and a second ingredient comprising an oxidizing agent, the first and second ingredients being mixed at time of use. The mixture comprises (a) a triazacyclononane compound (1) or a salt thereof, (b) an oxidizing agent in an amount of 0.1 to 12 wt.% in terms of hydrogen peroxide, and (c) 0.05 to 10 wt.% alkali agent, and has a pH of 7.5 to 12. (1) (2) [R to R each is hydrogen or C1-6 alkyl optionally substituted by OH, and R to R each is hydrogen, (substituted) C1-6 alkyl, (substituted) aralkyl, (substituted) heteroarylalkyl, (substituted) aryl, (substituted) heteroaryl, (substituted) C1-6 acyl, or a group represented by (2) (R to R each is hydrogen, C1-6 alkyl, aralkyl, or aryl and n is a number of 2 to 30).] The hairdye composition has an excellent decoloring ability and can dye the hair in a bright satisfactory tone. It is less apt to damage the hair or irritate the head skin.
摘要:
A dermatologic preparation containing a furan derivative represented by general formula (1) as the active ingredient, wherein X represents optionally substituted furan, benzofuran or isobenzofuran residue; and R and R represent each C1-C8 linear, branched or cyclic alkyl which may be substituted by X-CH2-N(R )- (wherein R represents C1-C6 linear or branched alkyl; and X is as defined above), or R and R together with the adjacent nitrogen atom may form a heterocycle which may be substituted by X-CH2- (wherein X is as defined above). The preparation is excellent in the effect of inhibiting wrinkling due to exposure to ultraviolet radiations, especially UV-B, and hence useful for the inhibition of wrinkling.
