Abstract

We investigated the growth-inhibitory activities of cosmetics and their preservatives against pathogens and resident skin bacteria. Of the tested cosmetics, preservatives such as parabens, 1,2-hexanediol, phenoxyethanol-contained toner, emulsion, cream and baby cream exhibited potent antibacterial effects against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Parabens, 1,2-hexanediol and phenoxyethanol inhibited the growth of pathogens, as well as skin-resident bacteria such as Staphilococcus epidermidis, Shigella flexneri, Enterobacter aerogenes and so on. The application of a basic cream containing phenoxyethanol to human skin was shown to disturb the skin microbiota: at the phylum level, Proteobacteria increased and at species level, 4P004125_s increased and Propionibacterium humerusii decreased. Based on these findings, parabens, 1,2-hexanediol and phenoxyethanol have antimicrobial activity and cosmetics containing phenoxyethanol may disturb skin microbiota.

화장품 및 화장품 함유 방부제에 대한 병원미생물과 사람의 피부서식세균들의 증식에 미치는 효과를 조사하였다. 파라벤, 1,2-헥산디올, 페녹시 에탄올과 같은 방부제를 함유한 토너, 에멀젼, 크림, 유아용크림은 포도상구균, 대장균, 녹농균에 대해 강한 방부효과를 보였으며, 파라벤, 1,2-헥산디올, 페녹시 에탄올과 같은 방부제들은 포도상구균, 대장균, 녹농균과 같은 병원균 및 Staphilococcus epidermidis, Shigella flexneri, Enterobacter aerogenes 등과 같은 일부 피부서식세균에 대한 강한 항균효과를 보였다. 사람의 피부에 페녹시 에탄올 함유 크림을 도포하였을 때, 피부서식 미생물들의 구성이 바뀌었다. 문 수준에서는 Proteobacteria가 증가하였고, 종 수준에서는 4P004125_s가 증가하였고, Propionibacterium humerusii 감소하였다. 이 결과들로부터 파라벤, 1,2-헥산디올, 페녹시 에탄올과 같은 방부제는 병원균에 대한 항균효과를 가짐과 동시에 페녹시 에탄올을 함유한 화장품은 피부세균군집에 변화를 줄 수 있음을 시사하고 있다.
