Seaweed polysaccharides-based gel to contest foot odour

This study demonstrated a one-pot process for the preparation of seaweed-based antibacterial foot care gel for the removal of odor. Foot gel comprised 97.5% water, 1.2% seaweed polymer, 0.2% bioactive molecule, and 1.1% preservative. The antibacterial efficiency of foot gel was tested against 14 bacterial strains, isolated from foot swab samples from five different healthy volunteers having foul foot odor. The 16S rRNA partial gene sequencing identification revealed all 14 bacterial strains were different Bacillus species. Foot gel was characterized using FTIR, Rheology, TGA, and gelling properties. The volunteer's feet were treated with just two drops (around 200 L) of foot care gel before wearing socks, which showed restriction in the growth of bacterial strains causing a foul odor within a few hours, therefore resulting in restrained the foul foot odor. Furthermore, the volunteer’s remarks about feeling freshness, coolness, dryness, and smooth feet after applying the foot gel were very encouraging. The shelf life of foot gel was monitored for up to six months and during that time, no significant change in rheological characteristics and antibacterial efficiency was observed. Foot gel was compared with commercially available foot care products and foul odor removal efficiency was found identical in both. Results of this study showed that the odor-removing efficacy of developed foot gel was found better than other commercial products.
