Abstract

Dandruff and underarm malodor are caused by microorganisms. Personal hygiene products containing various types of antimicrobial agents are used to relieve this condition, but the effect is not long-lasting. In this study, we tried to maintain the antimicrobial effect for a long time by covalently binding the antimicrobial component to the hair shaft. Antimicrobial activity against dandruff strains, underarm malodor associated bacteria, and skin microbial strains were evaluated using hair fixed with antimicrobial agents. The hair shaft covalently bonded of the QAC showed antibacterial activity against all tested bacteria. Although the antibacterial effect was slightly decreased after 5 washes, it was confirmed that the antibacterial effect still remained. The results of this study may be applied to personal hygiene products such as shampoos and deodorants that act as antimicrobial agents to prevent and alleviate dandruff and axillary odor.
