Science Fair 2013 - Antibacterial Gel
Transcript of Science Fair 2013 - Antibacterial Gel
• 1/3 cups of glycerin or aloe vera
• a measuring cup
• essential oil: clove, eucalyptus, lavender, etc.
• a mixing bowl
• a container
• gloves (optional) 1. Pour the ethyl alcohol and glycerin or aloe vera into the mixing bowl.
2. Add 8 to 10 drops of essential oil.
3. Mix all the ingredients together with a spoon.
4. Pour the mixture into the container and preserve at room temperature. It can be used for maximum 6 months. The recent studies about antibacterial gels show that our hypothesis was correct. Antibacterial gels are only substitutes for hand washing and does not remove all the bacteria on the skin. Some researchers even say that the bacteria that they remove aren't even the ones that cause the diseases in our bodies. But they do remove some beneficial bacteria on the skin and may cause bacteria to mutate. The alcohol in the antibacterial gel may also cause harm, since it causes the skin to dry and crack, allowing viruses to gain entry to the body. Soap and water is the best option to reduce the bacteria and protect your body. Garcia Garza, Regina

Ramirez, Garza, Carlos Federico We think that even though they remove a certain amount of bacteria, many remain. Abstract Purpose Introduction Our antibacterial gel turned out to be more liquid than we had expected. It will still be effective because of the alcohol, but if you prefer a more gel-like feeling, you could reduce the amount of ethyl alcohol, or add other ingredients, such as carbopol, to get the gel-like feeling. It will still work, as long as the ethyl alcohol takes up more than 60 percent of the gel. Procedures Results Conclusion Team Members However, alcohol-based hand sanitizers can also be very effective in cleaning the hands if there are no soap and water available and the hands are not visibly dirty. But the product should contain at least 60% alcohol to be effective. For people with more sensitive skin, both alcohol and the fragrance can irritate your hands. In that case, there are some other natural ways to make your own antibacterial gel. Herbs such as eucalyptus, tea tree oil, and lemon can be used alone or combined with cosmetic products or cleaning solutions to provide antibacterial effects.
