what is sebum and how could it have affected the handwashing experimental outcome?
Sebum is an oily substance produced by the sebaceous glands in the skin. It helps keep the skin moisturized and protects it from external factors.
In an experimental outcome focused on handwashing, sebum on the hands could potentially affect the results. If participants have a significant amount of sebum on their hands before washing, it may make it more difficult for the soap to effectively remove dirt and germs from the skin. This could result in a lower reduction of bacteria on the hands after washing compared to if the hands were clean before washing.
Additionally, the presence of sebum on the hands could also affect the feel and texture of the hands after washing. The oily residue may make the hands feel greasy or less clean, even if they are technically free of dirt and bacteria.
Overall, the presence of sebum on the hands could potentially impact the accuracy and effectiveness of the handwashing experiment results. It is important for researchers to take into consideration the baseline level of sebum on participants' hands before conducting experiments related to hand hygiene.
