＜抗菌・防腐剤の調製＞
下記表１の組成に基づき、抗菌・防腐剤Ａ〜Ｆを調製した。
Based on the composition shown in Table 1 below, antibacterial / preservatives A to F were prepared.
＜実施例、比較例＞
上記抗菌・防腐剤Ａ〜Ｆを用い、下記表２の組成に基づき、実施例および比較例に係る組成物を得た。これらの実施例、比較例の組成物を検体として、ハロー試験を実施した。ハロー試験は、５０μＬの検体を浸み込ませて室温で乾燥させた８ｍｍの円形のろ紙を、菌濃度を１０６個／ｍＬ〜１０７個／ｍＬに調製した試験菌液と十分混釈し凝固させた寒天培地上に置き、３５℃〜３７℃で３６時間培養後に、ハローを測定した。菌としては、黄色ブドウ球菌（ＳＣＤ寒天培地）、カンジダ アルビカンス（ＧＰ寒天培地）のそれぞれで行った。
その結果を測定方法は表２に示す。<Examples and comparative examples>
Using the antibacterial / preservatives A to F, compositions according to Examples and Comparative Examples were obtained based on the compositions shown in Table 2 below. A halo test was conducted using the compositions of these Examples and Comparative Examples as specimens. In the halo test, an 8 mm circular filter paper soaked with 50 μL of sample and dried at room temperature was sufficiently mixed with the test bacterial solution prepared at a bacterial concentration of 10 6 cells / mL to 10 7 cells / mL. After placing on a coagulated agar medium and culturing at 35 ° C. to 37 ° C. for 36 hours, halo was measured. As the bacteria, S. aureus (SCD agar medium) and Candida albicans (GP agar medium) were used.
The measurement method is shown in Table 2.
驚くべきことに、ヒバ油と銅化合物との混合系においてのみ、上記低濃度にて、カンジダ アルビカンスに対してもハローが観察された。つまり、このヒバ油と銅化合物との混合系では、低濃度で抗菌・防腐力が高いことが明らかとなった。 Surprisingly, halo was also observed against Candida albicans at the low concentration only in the mixed system of Hiba oil and copper compound. In other words, it became clear that the mixed system of Hiba oil and copper compound has high antibacterial and antiseptic power at low concentrations.
本発明の抗菌・防腐剤および外用組成物は、ヒバ油と銅化合物との混合物を含んでおり、少量にて抗菌・防腐効果を有するため、汎用性に富む。したがって、化粧品、医薬品等の種々の製品に適用することができる。 The antibacterial / preservative and the composition for external use of the present invention contain a mixture of Hiba oil and a copper compound and have an antibacterial / preservative effect in a small amount. Therefore, it can be applied to various products such as cosmetics and pharmaceuticals.
