FORMULASI FOOT SPRAY ANTI BAU KAKI BERBASIS NANO CHITOSAN DARI LIMBAH INDUSTRI UDANG

Abstract

One of the solutions to the problem of anti-odorous feet is the use of anti-odor products. One of the natural ingredients that have the potential as an anti-odor agent is chitosan. Chitosan in the form of nanoparticles is more reactive and has higher antibacterial activity. Until now, shrimp industrial waste has not been explored much, so that the utilization of shrimp industrial waste into nano chitosan can increase the added value of shrimp waste. This study aims to find the most effective foot spray formulation in inhibiting bacteria that cause foot odor. The stages of this research were the manufacture of chitosan, nano chitosan, foot spray formulation, physical properties test, antibacterial activity test, physical stability test, and irritation test. The manufacture of nanochitosan was done using the ionic gelation method. Chitosan was dissolved with distilled water, 0.1% TPP, and Tween 80 and disizing at a speed of 23,000 rpm to form stable nanoparticles. The nano chitosan concentration of 3,000 ppm gave the highest inhibitory power of 5.20 mm against S. epidermidis and 3.15 against Micrococcus sp. The degree of acidity, particle size, and sensory value of foot spray nano chitosan was stable during 8 weeks of storage, but the viscosity decreased significantly.
