Abstract:
An agent for preventing or ameliorating skin aging, which exhibits a more excellent effect on the suppression of formation, or the amelioration, of wrinkles on the skin or sagging skin. An agent for preventing or ameliorating skin aging, containing triterpenoid saponins represented by the following formula (1) as an active ingredient, wherein at least one of R1 and R2 is a tigloyl group and the other represents a tigloyl group or an angeloyl group; R3 represents a methyl group or a hydroxymethyl group; and R4 represents Glc, Xyl or Gal.
Abstract:
Wrinkling modifiers and anti-aging cosmetic preparations which contain guanidine derivatives of general formula (1) or salts thereof, wherein (a) is a group derived from a heterocyclic compound selected from among azetidine, pyrrolidine, piperidine, piperazine and morpholine; and R and R are each independently hydrogen, alkyl, hydroxyl, hydroxyalkyl, carboxyl, carboxyalkyl or amidino. The cosmetic preparations are excellent in the effect of suppressing wrinkling and the effect of making wrinkles disappear and exhibit an excellent feeling in use.
Abstract:
Skin pore minimizers containing as the active ingredient compounds of the following general formula: R1-OG or salts thereof [wherein R1 is C¿8-32? alkyl or alkenyl; and OG is a residue derived from a polyhydric alcohol, a monosaccharide, or an oligo- saccharide, at least one hydroxyl group of which is sulfated or phosphorylated, by removing a hydroxylic hydrogen atom]; and skin elasticity improvers containing as the active ingredient glyceryl ether derivatives of the following general formula: R?1O-CH¿2-CH(OX2)-CH2-OX1 or salts thereof [wherein R1 is as defined above; and X?1 and X2¿ are each hydrogen, -SO¿3?OH, or -PO(OH)2 with the proviso that the cases wherein both X?1 and X2¿ are hydrogen are excepted].
Abstract:
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.
