Antimicrobial Evaluation of Sport Roll-on Deodorant via Clinical Trials and Axilla Bacterial Identification of Indonesian Males with The Age Ranging from 26-40 Years Old
Body odor is an unpleasant smell that is caused by the interaction of sweat and bacteria on the
skin. According to some studies there are three bacteria that can cause body odor, which are
Corynebacterium, Staphylococcus, and Micrococcus. To counteract this interaction a cosmetic product
that has antimicrobial properties can be used. One example of this cosmetic product is deodorant.
Deodorant is a substance that is applied to the body to reduce axillary odor and prevent the growth of
bacteria by degrading the apocrine gland of the axillary area. Deodorants have three main mechanisms
to inhibit the body odor formation, which are inhibiting the sweat production, inhibit the axillary
microbial growth, and cover up the body odor with fragrance. Hence, this study was conducted to
observe and determine the antimicrobial activity of sport roll-on deodorant towards elderly male
subjects for three days through microbial enumeration at three different sampling times along with
bacteria identification using gram staining procedure. The sport-roll on deodorant was able to
significantly reduce the bacterial growth that occurs in the axillary area during the three day of the
clinical study (p < 0.05). However, the sport deodorant was not able to inhibit both Corynebacterium and
Staphylococcus, which are specific bacteria that can cause body odor.
