PROBLEM TO BE SOLVED: To solve the problem that: currently, in the cosmetics industry, consumers concern about the safety of products has been growing in association therewith, as to raw materials to be compounded in products, those derived from natural matter tend to be favored as for antiseptics in particular to be compounded in products, their safety, irritancy to the skin, etc., are under concern however, as three-year quality guarantee period is required, in principle, for products under the Pharmaceutical Affairs Law, use of antiseptics is inevitable in the present situation therefore, in the cosmetics industry, in order to respond to consumers demand for safety, efforts for developing natural matter-derived antiseptics are underway despite the fact, satisfactory antiseptic materials in terms of safety, functionality and handleability have been unable to be developed yet.SOLUTION: It has been found that: by compounding a cosmetic with 2-7%, preferably 5-7%, of a component obtained by extraction from Artemisia absinthium, a kind of plant belonging to the genus Artemisia, Compositae family, the resultant cosmetic sufficiently exhibits its function as antiseptic. Extract from Artemisia absinthium has been originally used in beverages from old times, being used currently as a bittern ingredient as a food additive, a number of safety tests have been conducted in association therewith, thereby being deemed as a highly safe material. In addition, the extract is available in a water-soluble liquid, being a material very easy to handle with high solubility in producing cosmetics.COPYRIGHT: (C)2013,JPO&INPIT【課題】 現在化粧品業界では消費者の製品に対する安全性への関心が高まっている。それに伴い、製品に配合される原料についても天然物由来のものが好まれる傾向にある。特に製品中に配合される防腐剤は安全性や肌への刺激などが懸念されているが、薬事法上製品には原則として3年間の品質保証期間を義務づけているため防腐剤の使用が避けられないという現状がある。そこで、化粧品業界では消費者の安全性への要望に応えるため天然物由来の防腐剤を開発しようと努力が行われているが、未だに安全性、機能性、扱いやすさにおいて満足のいく天然物由来の防腐原料を開発出来ずにいる。【解決手段】 本発明は、キク科ヨモギ属の一種であるニガヨモギから抽出して得られた成分を化粧品に2~7%、さらに好ましくは5~7%配合することで防腐剤としての機能を十分に発揮することを発見した。ま
