Efficiency of soap and alcohol gel in inhibiting bacteria

Abstract

washing hands with soap or alcohol gel It is the easiest process to prevent germs from entering the body. To see the importance of proper hand washing The purpose of this research was to study the efficiency of washing hands with soap. or alcohol gel to inhibit the growth of bacteria on the palms of volunteers. By collecting samples before washing hands. and after washing hands properly, including washing hands with soap and washing hands with alcohol gel. Experiment 1 examined the presence of coliform bacteria on the palm of the hand using the primary coliform bacteria test kit (SI-2), and Experiment 2 examined all bacteria on the palm of the hand using the kit. Test all bacteria on food contact containers and hands (Compact Dry TC). Samples were collected from the hands of 29 volunteers who were willing to participate in the project. The volunteers were building employees in the area. Thung Phaya Thai Subdistrict, Ratchathewi District, Bangkok It is a convenient way to collect samples. From the test, it was found that washing hands with soap or alcohol gel can inhibit the growth of coliform bacteria on the hands of applicants by 100 percent. In testing to determine the total amount of bacteria, it was found that before washing hands with soap on the average bacteria on the palms was 47 ±  30.41. Colony/25 square centimeters and decreased to an average of 21 ±  29.70 colonies/25 square centimeters after washing hands. As for washing hands with alcohol gel, the average number of colonies was reduced from 63 ±  26.92 colonies/25 square centimeters to 12 ±  11.18 colonies/25 square centimeters. From the test, it can be concluded that hand washing is done correctly, including washing hands with soap. Or, alcohol gel can inhibit the growth of bacteria, with the efficiency of inhibiting bacteria of both types of hand washing not being different.
