PURPOSE:To provide a pimple-preventive cosmetic composition having excellent antibacterial power to acneform bacteria and free from side-effect to cause dermatic allergy in contrast to conventional sterilizing agent. CONSTITUTION:The objective pimple-preventive cosmetic composition contains 0.001-5.0wt.% (preferably 0.01-2.5wt.%) of a water-extract and/or an organic solvent extract of a plant of the genus Caesalpinia as an active component. The plant of the genus Caesalpinia is e.g. Caesalpinia sappan, Caesalpinia crista, Caesalpinia magnifoliolata, Caesalpinia minax, Caesalpinia sepiaria and Caesalpinia sepiaria var. pubscens. Caesalpinia sappan is most preferable among the above plants because an extract having especially excellent antibacterial power to acneform bacteria is obtained from the plant. The extraction solvent is e.g. benzene, ethyl ether, chloroform, ethyl acetate, acetone, methanol, ethanol or butyl alcohol. |
