    摘要: PROBLEM TO BE SOLVED: To obtain a safe and persistent external agent exhibiting excellent antiphotooxidation action by combining a specific antioxidation agent including chlorogenic acid with an electron donor. SOLUTION: This agent is produced by using an antioxidation agent having photoregenerating action and free from activity to reduce oxygen in the photoregeneration reaction in combination with an electron donor necessary for the regeneration of the antioxidation agent. The antioxidation agent is preferably one or more components selected from o-hydroxyphenol compound, especially chlorogenic acid and coffeic acid. The electron donor is preferably sugars or EDTA. The amount of the antioxidation agent is preferably 0.001wt.%, especially 0.001-1.0wt.% based on the total external agent. The compounding molar ratio of the electron donor to the antioxidation agent is preferably >=5. The antiphotooxidation agent for external use is useful as cosmetics, drugs, quasi-drugs, etc., especially an antiultraviolet agent for external use, especially external agent for skin or hair.
