Abstract

Body odor is promoted by perspiration as sebum and other secretory substances in sweat are decomposed into odorous substances by residence bacteria such as Staphylococcus aureus on the skin surface. Staphylococcus aureus grows when the skin pH increases above 5.5 and stimulates skin, resulting the generation of strong body odor and causing skin itching and/or reddening. In order to suppress the growth of Staphylococcus aureus on the skin, weak-acid polyester was prepared by introducing acid groups onto polyester fabric and evaluated its antibacterial /deodorant effect on human subjects. The results confirmed that the growth of Staphylococcus aureus on the skin was suppressed and in consequence less body odor was generated after perspiration.
