Abstract:
PROBLEM TO BE SOLVED: To obtain a blood circulation-promoting agent which exhibits a blood circulation-promoting action, gives a persistent warm-sensitive effect to skin, scarcely gives an unpleasant skin-irritating touch to a human body, and is useful for medicines or cosmetics, by including a specific veratryl ether derivative. SOLUTION: This blood circulation-promoting agent contains a veratryl ether derivative of the formula [R1 is a 1 to 18C alkyl or a 7 to 24C aralkyl; (m) is 0 to 2] as an active ingredient. The content of the compound of the formula is preferably 0.001 to 10 wt.%. One or more compounds among the compounds of the formula may be used for the blood circulation-promoting agent. One or more other compounds giving warm-sensitive touches or one or more plant extracts having blood circulation-promoting effects, such as the powder of red pepper, may together be used to further improve the heat-sensitive effect without strengthening a skin-irritating touch. The compound of the formula can be obtained by reacting veratryl alcohol with an alcohol in the presence of a strong acid as a dehydrating agent.
Abstract:
