Study of the water hyacinth extract concentration to the characteristics of gel hand sanitizer

Abstract

Hand hygiene is one of the most important things in the spread of bacteria and virus. The spread of this organism can be stopped by cleaning hands either by washing or sanitizing. Water hyacinth extract contain high flavonoid and tannin which can be used as an active agent in hand sanitizer. Three different extract concentration were examined which are 8, 10 and 12%. Organoleptic test were conducted to examine the shape, colour and scent of the hand sanitizer. Biological test were performed to find the effectiveness of the hand sanitizer against the bacteria. The results showed that hand sanitizer product with 8% water hyacinth extract have better potential in killing the bacteria compared to the other concentration.
